Common Causes for Android Text Message Sending Failures

Dealing with an Android phone that refuses to send text messages can be incredibly frustrating. Whether you’re trying to coordinate a simple meeting or sending a vital update, the inability to communicate is a significant problem. Several factors, from the mundane to the complex, can be the root of the issue. Understanding these common culprits is the first step in regaining your texting functionality and ensuring your messages get delivered.

Full Storage on the Device

One of the most frequent, and often overlooked, reasons for text message sending failures is a full storage capacity on your Android device. When your phone’s internal storage is maxed out, it doesn’t have the space to save new data, including outgoing text messages. This is similar to trying to squeeze one more item into a packed suitcase; there’s simply no room.Think of it this way: your phone stores text messages, photos, videos, apps, and other files.

If the storage is at its limit, the system might not be able to create the temporary files necessary to send a text.Here’s a breakdown of how this happens:

• The phone attempts to send the message.
• The operating system tries to create temporary files to process the message.
• If there’s no available storage space, the file creation fails.
• The message is not sent, and you might receive an error message.

Clearing up space is often the solution. Consider deleting unnecessary files, uninstalling unused apps, or moving photos and videos to cloud storage or an external SD card.

Incorrect Network Settings, Including APN Configurations

Another common issue stems from incorrect network settings, particularly your Access Point Name (APN) configuration. Your APN settings are crucial; they tell your phone how to connect to your mobile carrier’s network to access the internet and send multimedia messages (MMS). If these settings are wrong, your phone might be unable to send texts, especially those containing images or videos.Imagine the APN as a detailed map that guides your phone to your carrier’s messaging servers.

If the map is inaccurate, the message will never reach its destination.
Here’s a deeper dive into how this impacts message sending:

• Your phone uses the APN settings to establish a data connection.
• This data connection is required for sending and receiving MMS messages and, in some cases, standard text messages.
• If the APN settings are incorrect, your phone can’t establish the connection.
• Consequently, the message fails to send.

To resolve this, you typically need to:

1. Check your APN settings with your mobile carrier.
2. Enter the correct settings in your phone’s settings menu.
3. Restart your phone to apply the changes.

Incorrect APN settings are a frequent problem, especially after software updates or when switching SIM cards. This underscores the importance of regularly verifying and updating these settings to ensure smooth text messaging.

The Messaging App Itself

The messaging app you use can also be the source of your text message sending woes. Like any software, messaging apps are prone to bugs, glitches, and compatibility issues. These problems can range from minor inconveniences to complete sending failures.Consider the app as a complex machine. Even the most well-designed machine can have a faulty component or a programming error that disrupts its operation.Here’s how app-related issues can cause sending failures:

• Software bugs within the app can prevent messages from being sent.
• Outdated app versions might not be compatible with your phone’s operating system.
• Corrupted app data can interfere with sending messages.

Troubleshooting often involves:

1. Updating the messaging app to the latest version.
2. Clearing the app’s cache and data.
3. Uninstalling and reinstalling the app.

Furthermore, different messaging apps have varying levels of reliability. Some apps are known for their robust performance, while others may be more prone to issues. Choosing a reliable app and keeping it updated is a key factor in ensuring smooth text message sending.
If the problem persists, it might be necessary to switch to a different messaging app to see if the issue is resolved.

Common Error Messages and Potential Solutions

When your Android phone fails to send a text message, it often provides an error message. These messages can offer valuable clues about the problem’s cause and potential solutions. Understanding these error messages can save you time and frustration.Here’s a table that breaks down some common error messages and their corresponding solutions:

Error Message	Potential Cause	Solution	Additional Notes
“Message not sent. Tap to retry.”	Network connectivity issues, APN problems, or temporary server outage.	Check your network connection, verify APN settings, and try sending the message again later.	This is a very common error. Check your signal strength first.
“Message sending failed.”	Full storage, app bugs, or recipient’s number blocked.	Clear storage space, update or reinstall the messaging app, and check if you’ve blocked the recipient.	This can also indicate issues with the message format or content.
“Unable to send message. Please try again later.”	Server-side issues with your carrier, temporary phone problems.	Wait a while and try sending the message again. Contact your carrier if the problem persists. Restart your phone.	This might be related to your account or carrier’s infrastructure.
“MMS not sent. Check your mobile data connection.”	Incorrect APN settings, disabled mobile data, or insufficient data balance.	Verify your APN settings, ensure mobile data is enabled, and check your data plan balance.	MMS messages require a data connection.

Troubleshooting Network Connectivity Problems

It’s a frustrating moment when you try to send a text and nothing happens. Before you tear your hair out, let’s explore the often-overlooked culprit: your network connection. A stable and active network is the lifeblood of your texts. We’ll delve into some practical steps to diagnose and fix network-related issues that might be preventing your messages from reaching their destination.

Verifying Cellular Network Connectivity

First things first: Is your phone even connected to a cellular network? Seems obvious, but it’s a critical starting point.Here’s how to check:* Look at the status bar at the top of your screen. You should see an indicator that looks like a series of bars or a network name (e.g., “Verizon,” “AT&T”). If there are no bars or a “No Service” message, your phone isn’t connected to the network.

• Alternatively, open your phone’s settings app. Navigate to “Connections” or “Network & Internet” (the exact wording varies depending on your Android version).
• Check the “Mobile networks” or “Cellular network” section. It should show your network provider and indicate whether you are connected. You might see details about signal strength here. If you see “Disconnected” or similar, there’s your problem.
• Try making a phone call. If the call fails, it reinforces the network connectivity issue. If it works, the problem may be specific to text messaging.

Restarting the Phone to Resolve Text Message Sending Problems

Sometimes, a simple restart is the digital equivalent of a good night’s sleep for your phone. It can clear out temporary glitches and refresh your system.Here’s how to do it:

• Press and hold the power button until a menu appears.
• Select “Restart” or “Reboot.”
• Wait for your phone to completely shut down and then turn back on.

This process closes all running apps and processes, potentially resolving minor software conflicts that might be hindering your text messages. It’s a quick and often effective first step.

Toggling Airplane Mode to Refresh the Network Connection

Airplane mode acts like a digital circuit breaker, disconnecting your phone from all wireless networks (cellular, Wi-Fi, and Bluetooth). Toggling it on and off can often force your phone to re-establish a connection with the cellular network, which might fix the text message issue.Here’s how:

• Swipe down from the top of your screen to access the quick settings panel.
• Tap the airplane icon (usually looks like an airplane). This turns Airplane mode on.
• Wait for about 15-30 seconds.
• Tap the airplane icon again to turn Airplane mode off.

Your phone will then attempt to reconnect to the cellular network. Check your signal bars and try sending a text message.

Troubleshooting Wi-Fi Calling Issues Impacting Text Messaging

Wi-Fi calling allows you to make and receive calls (and sometimes texts) over a Wi-Fi network instead of a cellular connection. While convenient, it can introduce its own set of problems. If you’re experiencing text message issues and Wi-Fi calling is enabled, consider these points:* Check Wi-Fi Connection: Ensure your phone is connected to a stable Wi-Fi network. Weak or intermittent Wi-Fi can disrupt text messaging.

Go to your phone’s settings and verify your Wi-Fi status.

Wi-Fi Calling Settings

Navigate to your phone’s settings and look for the “Wi-Fi Calling” option (it may be under “Connections” or “Network & Internet”). Make sure Wi-Fi calling is enabled. If it is, try disabling it temporarily to see if your text messages start sending over the cellular network.

Network Congestion

Like any network, Wi-Fi can get congested. If many devices are using the same Wi-Fi network simultaneously, it can slow down data transfer, potentially impacting text messages.

Router Issues

Sometimes, the problem lies with your Wi-Fi router. Try restarting your router (unplug it from the power outlet for about 30 seconds and plug it back in) to refresh its connection.

Provider Support

Contact your mobile carrier to confirm that Wi-Fi calling is properly configured on your account and that there are no known issues in your area.Wi-Fi calling problems often manifest as delays in sending or receiving texts, or even complete message failures. By methodically checking these areas, you can pinpoint whether Wi-Fi calling is the culprit.

Resetting Network Settings on an Android Phone

If the above steps don’t work, resetting your network settings is a more drastic but often effective measure. This resets your Wi-Fi, mobile data, and Bluetooth settings to their default values, which can resolve configuration conflicts.Before you proceed, be aware that you’ll need to re-enter your Wi-Fi passwords and re-pair Bluetooth devices after this process.Here’s how to do it:* Open the Settings app on your Android device.

• Go to “System” or “General management” (the exact wording varies depending on your phone’s manufacturer).
• Tap on “Reset options.”
• Select “Reset Wi-Fi, mobile & Bluetooth.”
• Confirm your choice. You may need to enter your PIN or password.
• Your phone will reset the network settings and restart.

After the restart, reconnect to your Wi-Fi networks and re-pair your Bluetooth devices. Test sending a text message. This process clears out potentially problematic network configurations that might be hindering your messages.

Examining Messaging App Settings

Let’s delve into the often-overlooked realm of your Android’s messaging app. It’s the silent workhorse, handling the crucial task of delivering your digital missives. Sometimes, a tweak here or a check there is all it takes to get things back on track. Understanding the app’s inner workings is key to solving sending issues.

Identifying and Changing the Default Messaging App

The default messaging app on your Android is the one your device uses automatically to send and receive texts. It’s usually pre-installed by the manufacturer or your carrier. However, you have the freedom to switch it up!To find out which app is currently in charge, simply try sending a text. The app that opens is your default. Changing it is a straightforward process:

• Navigate to your device’s Settings app.
• Search for “Default apps” or “Apps & notifications” and then “Default apps.” The wording might vary slightly depending on your Android version and phone manufacturer.
• Tap on “SMS app” or “Messaging app.”
• You’ll see a list of installed messaging apps. Select the one you want to use as your default. The next time you send a text, it will use the app you’ve chosen.

Diving into the messaging app’s settings is like taking a peek under the hood of a car. It reveals crucial configuration options. These settings control how your messages are sent, received, and handled.To access these settings:

• Open your messaging app.
• Tap on the menu icon (usually three vertical dots or three horizontal lines) or search for “Settings”.
• Look for options like “SMS/MMS settings” or similar. The exact wording will depend on the app.

Inside these settings, you’ll find various parameters to examine. Here are some of the most important:* SMS settings: This section typically deals with text messages. You can usually find options to enable/disable SMS delivery reports (notifications that tell you if your message was successfully sent), set the character limit for a single SMS (usually 160 characters), and possibly configure other SMS-related features.

MMS settings

These are for multimedia messages (pictures, videos, etc.). You’ll find settings related to group messaging, auto-download of MMS messages, and sometimes the ability to limit the size of MMS messages you can send or receive.

Notifications

Check these to ensure that you have notifications enabled for new messages, and that they’re configured the way you like them.

Clearing the Cache and Data of the Messaging App

Sometimes, a bit of digital spring cleaning is all that’s needed. Over time, the messaging app accumulates temporary files (cache) and data. These files can occasionally become corrupted, leading to various issues, including sending failures. Clearing the cache and data can often resolve these problems.Here’s how to clear the cache and data:

• Go to your device’s Settings app.
• Tap on “Apps” or “Apps & notifications” and then “See all apps” or “App info”.
• Find your messaging app in the list and tap on it.
• Tap on “Storage & cache.”
• Tap “Clear cache.” If the problem persists, tap “Clear storage” or “Clear data.” This will erase the app’s settings, so you might need to reconfigure them. Your messages will generally not be deleted, but it’s always wise to back them up if you’re concerned.

• Tap on “Updates available” to see a list of apps that have updates.
• Find your messaging app and tap “Update.” If the app doesn’t appear in the list, it’s already up to date.

SMSC Number Verification, Why is my android not sending text messages

The SMS Service Center (SMSC) number is a crucial setting. It’s the phone number of the server that handles sending and receiving SMS messages. An incorrect SMSC number can prevent your messages from being sent. While it is rare for this setting to be incorrect, it is essential to check if you suspect a problem.

An example of an incorrect SMSC number might be one that is formatted incorrectly or one that is outdated for your region. For instance, a number that’s missing the country code or includes extra digits. A correct SMSC number will vary depending on your mobile carrier and region. You can typically find the correct number by searching online for your carrier’s SMSC number or by contacting your carrier’s customer support.

SIM Card and Account Issues: Why Is My Android Not Sending Text Messages

Sometimes, the reason your Android phone refuses to send text messages isn’t a software glitch or a network hiccup, but rather something far more fundamental: your SIM card or your mobile account. These components are the unsung heroes of your texting adventures, and when they falter, your ability to communicate can be seriously hampered. Let’s delve into the nitty-gritty of SIM cards, account statuses, and how they impact your ability to send those crucial messages.

Malfunctioning SIM Card Impact

A faulty SIM card can act as a silent saboteur, quietly preventing your phone from sending texts. Think of the SIM card as the gatekeeper to your mobile network; it’s the tiny chip that authenticates your phone and grants it access to the cellular world. If this gatekeeper is damaged, corrupted, or simply not making a good connection, your text messages won’t even leave your phone, and the sender might not even know it.

You’ll likely encounter error messages, or the messages might just sit there, perpetually “sending.”

Checking SIM Card Status

Fortunately, Android offers a way to peek behind the curtain and check your SIM card’s status. It’s like a quick diagnostic test to see if everything’s running smoothly.To do this:

1. Open your phone’s Settings app. This is usually represented by a gear icon.
2. Tap on “Connections” or “Network & Internet.” The wording might vary slightly depending on your Android version.
3. Look for an option labeled “SIM card manager,” “SIM cards,” or something similar.
4. Within this menu, you should see information about your SIM card, including its status. It should say “Active” or “Connected.” If it says “Inactive,” “No SIM card detected,” or something similar, you’ve likely found the culprit.

Removing and Reinserting the SIM Card

Sometimes, the fix is as simple as a good old-fashioned reset. Just like restarting your computer can solve many problems, removing and reinserting your SIM card can often clear up any minor glitches. This process can help re-establish a solid connection between the SIM card and your phone.Here’s how to do it safely:

1. Turn off your phone completely. This is crucial to prevent any potential damage.
2. Locate the SIM card tray. This is usually a small slot on the side or top of your phone. You’ll need a SIM ejector tool (a small pin-like device that usually comes with your phone) or a paperclip to open it.
3. Insert the SIM ejector tool into the small hole on the SIM card tray and gently push until the tray pops out.
4. Carefully remove the SIM card from the tray. Inspect it for any visible damage, such as scratches or bends.
5. Clean the SIM card gently with a soft, dry cloth.
6. Reinsert the SIM card into the tray, ensuring it’s properly aligned.
7. Slide the tray back into your phone until it clicks into place.
8. Turn your phone back on and check if you can send text messages.

Contacting the Mobile Carrier

If, after troubleshooting, you’re still unable to send text messages, it’s time to reach out to your mobile carrier. They can access your account information and pinpoint any issues on their end. Your carrier can verify your account status, confirm that text messaging is enabled on your plan, and investigate any network-related problems that might be preventing you from sending messages.

They can also check for any temporary outages or service interruptions in your area.To contact your mobile carrier, you can typically:

• Call their customer service number. This number is usually available on their website or on your monthly bill.
• Visit their local store.
• Use their online chat support.
• Check their website for troubleshooting guides or FAQs.

Be prepared to provide your account information and describe the problem you’re experiencing. They may ask you to perform some troubleshooting steps or provide a temporary solution.

SIM Card Problem and Resolution Table

Here’s a table summarizing potential SIM card problems and their possible solutions. This is a handy reference guide to keep in mind if you’re experiencing text messaging troubles.

Dealing with Blocking and Filtering

Sometimes, your texts simply vanish into the digital ether, never reaching their intended destination. One potential culprit? The dreaded block. Or, perhaps, a less malicious but equally frustrating filter. Understanding how blocking and filtering work on Android is key to getting your messages delivered.

Let’s delve into this often-overlooked area of text messaging woes.

Checking for Blocked Numbers on Your Device

Before you start blaming the recipient, check if you’ve accidentally blocked their number. This is a common oversight. Most Android devices make it relatively straightforward to review your blocked contacts list.To verify if a number is blocked on your Android device, navigate to your phone’s settings. The exact path may vary slightly depending on your device manufacturer and Android version, but generally, you’ll find it within the “Phone” or “Call” settings.

Look for an option like “Blocked numbers,” “Block list,” or “Blocked contacts.” Within this section, you should see a list of all the phone numbers you’ve blocked. If the recipient’s number appears on this list, that’s the reason your messages aren’t going through. Unblocking the number should resolve the issue.

Verifying if Your Number is Blocked on the Recipient’s Device (If You Have Access)

If you have access to the recipient’s phone (perhaps they’ve asked you to troubleshoot with them), you can directly check if your number is blocked.The process is essentially the same as checking for blocked numbers on your own device. The recipient needs to go into their phone’s settings, find the “Blocked numbers” or similar section, and review the list. If your number is present, it’s blocked.

If not, the issue likely lies elsewhere. Another, less direct method is to try sending a text message and see if it goes through. If it doesn’t, and you’ve ruled out other issues, blocking is a likely cause. This assumes the recipient has not silenced your messages in a different way, such as by silencing notifications.

Checking Messaging App Filtering and Spam Protection Settings

Messaging apps often include built-in features designed to filter out spam or unwanted messages. These features, while helpful in many cases, can sometimes inadvertently block legitimate messages.Most messaging apps, including Google Messages, Samsung Messages, and others, allow you to configure spam protection settings. Within the app’s settings, look for sections related to “Spam protection,” “Blocked messages,” or “Filtering.” Examine these settings carefully.

You might find that a particular contact has been flagged as spam, or that a general filtering level is set too aggressively. Review the settings and adjust them as needed. You can often choose to disable spam filtering altogether, or to customize the level of filtering. Remember that disabling these features may result in more unwanted messages.

Impact of Third-Party Apps on Message Sending

The world of Android is filled with third-party apps, and some of these apps can impact your ability to send text messages. Specifically, call-blocking apps and apps designed to manage contacts or communications can sometimes interfere with message delivery.Call-blocking apps, for example, often have the capability to block text messages from specific numbers. If you’re using such an app, check its settings to ensure it’s not inadvertently blocking the recipient’s number.

Some contact management apps also have features that can affect messaging, such as the ability to automatically categorize or filter messages. Review the settings of any third-party apps you’re using that relate to communication or contact management. It’s also worth temporarily disabling these apps to see if that resolves the issue.

Managing Blocked Numbers in Android Messaging Apps

Different Android messaging apps offer different ways to manage blocked numbers. Here’s a breakdown for some of the most popular apps:

• Google Messages: Open the app, tap the three dots (menu) in the top right corner, then select “Blocked contacts.” From there, you can view and manage your blocked numbers. You can also block a number directly from a conversation by tapping the three dots and selecting “Block.”
• Samsung Messages: Open the app, tap the three dots (menu) in the top right corner, then select “Settings.” Tap on “Block numbers and spam.” Here, you can manage your blocked numbers and spam settings. You can also block a number from a conversation by tapping the three dots and selecting “Block number.”
• WhatsApp: Open the chat with the contact, tap their name at the top, scroll down to the bottom, and you’ll see the “Block” option. To unblock, navigate to Settings > Privacy > Blocked contacts and select the contact.
• Signal: Open the app, tap the three dots (menu) in the top right corner, then select “Settings.” Tap on “Privacy,” then “Blocked.” You can manage your blocked numbers from there. To block a number, open the conversation, tap the contact’s name, and select “Block.”

Addressing Software and Hardware Issues

Sometimes, the reason your Android device isn’t sending text messages goes deeper than app settings or network hiccups. It could be a problem with the software running the show or even the physical components of your phone. Diagnosing these issues requires a systematic approach, but don’t worry, we’ll break it down step-by-step. Let’s dive into some troubleshooting techniques that might just get your texts flying again.

Identifying the Scope of the Problem

Determining whether the problem lies within your messaging app or extends to the broader system is the first critical step. This distinction helps you focus your troubleshooting efforts. Is it a localized issue, or is your phone generally struggling?

• Test with Other Apps: Try sending a text message using a different messaging app. If the message sends successfully, the problem likely lies within your primary messaging app. If the problem persists across multiple apps, the issue is more likely system-wide.
• Check System Functions: Verify if other functions that rely on network connectivity are working. Can you browse the internet? Can you make phone calls? If these functions are also failing, it points to a broader network or system issue.
• Observe Error Messages: Pay close attention to any error messages you receive. These messages can provide valuable clues about the source of the problem. For example, a “Message not sent” error might indicate a network issue, while an error specific to your messaging app might suggest a problem with the app itself.

Performing a Factory Reset

A factory reset returns your Android device to its original state, as if it were brand new. This can be a drastic measure, but it often resolves deep-seated software issues that other troubleshooting steps haven’t fixed. Before you begin, though, it’s crucial to back up your data.

Data Backup Considerations:

Before initiating a factory reset, back up all your important data to avoid permanent loss. You can back up your data using your Google account or by connecting your phone to a computer.

• Google Account Backup: Most Android devices automatically back up data like contacts, calendar events, and app data to your Google account. Go to your phone’s Settings, then “Accounts,” and ensure your Google account is set up for automatic syncing.
• Local Backup: You can also create a local backup of your device using the built-in backup features or a third-party app. This backup can include photos, videos, documents, and other files.
• Backup to Computer: Connect your phone to a computer and manually copy important files like photos, videos, and documents.

Performing the Factory Reset:

Once you’ve backed up your data, you can proceed with the factory reset. The exact steps may vary slightly depending on your Android device’s manufacturer and version.

1. Open Settings: Go to your phone’s Settings app.
2. Find Backup & Reset: Search for “Backup & reset” or “Factory reset.” The location may vary depending on your device.
3. Select Factory Reset: Choose the “Factory data reset” or “Reset phone” option.
4. Confirm: You may be prompted to enter your PIN or password. Then, confirm that you want to erase all data.
5. Wait for the Reset: The device will reboot and erase all data, then restore to its factory settings. This process can take several minutes.

Checking and Installing System Updates

Keeping your Android system updated is essential for several reasons, including bug fixes, security patches, and improved performance. Updates often address software glitches that could be interfering with your messaging app.

• Accessing the Update Feature: The method for checking for updates varies by manufacturer. Typically, you can find this option in your device’s Settings menu. Look for options like “System,” “About phone,” or “Software update.”
• Checking for Updates: Once you find the update section, tap on “Check for updates.” The device will search for available updates.
• Downloading and Installing: If an update is available, you’ll be prompted to download and install it. Make sure you’re connected to Wi-Fi to avoid using your data plan. Follow the on-screen instructions to complete the installation.

Assessing for Hardware Issues

Sometimes, the problem isn’t software-related; it’s a hardware issue. A faulty antenna, for example, can severely impact your phone’s ability to send and receive text messages. Assessing for hardware problems requires a keen eye and a bit of detective work.

• Signal Strength: The most obvious indicator of a hardware issue is poor signal strength. Check the signal bars at the top of your screen. If you consistently have weak or no signal, it could indicate a problem with your antenna.
• Physical Inspection: Examine your phone for any physical damage, such as cracks or dents. These can sometimes affect the antenna’s performance.
• Troubleshooting Steps: If you suspect a hardware issue, consider the following:
  • Restart your phone: A simple restart can sometimes resolve minor hardware glitches.
  • Try a different SIM card: If possible, test your SIM card in another phone to rule out a SIM card issue.
  • Contact your carrier or a repair shop: If the problem persists, you may need to contact your carrier or a professional repair shop to diagnose and repair the hardware issue.

Illustration: Android Phone Signal Bars and Message Sending

Imagine a visual representation of your phone’s signal strength, presented as a series of bars at the top of your screen. Let’s explore how these bars correlate with your ability to send text messages.

Scenario 1: Full Signal (Four Bars Displayed)

The signal bars are completely filled, indicating a strong and stable connection. You’re in an area with excellent network coverage. Text messages should send and receive instantly without issues. Think of it like a clear, sunny day – communication is effortless.

Scenario 2: Good Signal (Three Bars Displayed)

Three bars are visible, showing a good signal strength. You should be able to send and receive messages without major problems, although there might be occasional delays. This is akin to a partly cloudy day; the connection is still reliable, but minor interruptions are possible.

Scenario 3: Fair Signal (Two Bars Displayed)

Two bars are visible, indicating a fair signal strength. Sending messages may take longer, and you might experience some delays or failed send attempts. Think of this like a day with light rain; communication is possible, but you may need to find a better spot.

Scenario 4: Weak Signal (One Bar Displayed)

Only one bar is visible, signaling a weak connection. Sending messages becomes increasingly difficult. You might experience frequent failed attempts or significant delays. It’s like a stormy day; communication is a struggle, and you may need to move to a location with better coverage.

Scenario 5: No Signal (No Bars Displayed)

There are no signal bars, indicating no network connection. You are either out of range of your carrier’s network or experiencing a severe hardware or software issue. You won’t be able to send or receive any text messages. It’s like being in a complete blackout; all communication is cut off.

Important Note: Signal strength can vary depending on your location, the network infrastructure, and your phone’s hardware. Even with full signal, occasional issues can occur due to temporary network congestion or other factors. However, consistent problems, especially with weak or no signal, suggest potential hardware or network issues that require further investigation.
