Why does WhatsApp say Failed to send SMS to the specified number? What should I do on Android - in detail?
When you encounter the message "Failed to send SMS to the specified number" in WhatsApp on your Android device, it indicates that there was an issue with sending a verification code via SMS. This is crucial for completing certain actions such as verifying your phone number or logging into a new device. Below are several steps you can take to troubleshoot and resolve this issue:
-
Check Your Internet Connection: Ensure that your Android device has a stable internet connection, either through Wi-Fi or mobile data. A poor or unstable connection can prevent the SMS from being sent successfully.
-
Verify Your Phone Number: Double-check that you have entered the correct phone number in the international format (e.g., +1 123 456 7890). Any mistakes in the number can lead to delivery failures.
-
Restart Your Device: Sometimes, a simple restart can resolve temporary glitches. Turn off your Android device and then turn it back on. After restarting, try sending the SMS again.
-
Check for System Updates: Outdated software can sometimes cause compatibility issues. Go to Settings > System > System Update and check if there are any pending updates. Install them if available.
-
Clear App Cache and Data: Clearing the cache and data of WhatsApp can help resolve minor bugs. Go to Settings > Apps > WhatsApp > Storage & cache, then tap on "Clear Cache" and "Clear Data". Note that clearing data will log you out of your account, so make sure you have backed up any important information.
-
Use a Different SIM Card: If possible, try using a different SIM card in your Android device. Sometimes, issues with the SIM card itself can prevent SMS from being sent or received.
-
Enable Permissions: Ensure that WhatsApp has the necessary permissions to send and receive SMS. Go to Settings > Apps > WhatsApp > Permissions, and make sure that "SMS" is enabled.
-
Contact Your Mobile Carrier: There might be issues with your mobile carrier's network that are preventing the SMS from being delivered. Contact your service provider for assistance and to ensure there are no restrictions on sending or receiving SMS messages.
-
Try Alternative Verification Methods: If WhatsApp supports alternative verification methods, such as a phone call or email, try using those options instead of SMS.
-
Reinstall WhatsApp: As a last resort, you can uninstall and then reinstall WhatsApp from the Google Play Store. This can help resolve any underlying issues with the app itself.
By following these steps, you should be able to identify and resolve the issue preventing WhatsApp from sending an SMS verification code to your specified number on your Android device.
