Why does WhatsApp say Failed to send SMS to the specified number - briefly?
When attempting to send an SMS via WhatsApp, you might encounter the message "Failed to send SMS to the specified number." This typically occurs due to one of two reasons: either the recipient's phone number is incorrect or there are issues with your internet connection or mobile network.
Why does WhatsApp say Failed to send SMS to the specified number - in detail?
When you encounter the message "Failed to send SMS to the specified number" on WhatsApp, it typically indicates that the app was unable to complete the verification process via SMS. This issue can stem from several factors, each of which is crucial to understand for effective troubleshooting.
Firstly, ensure that your phone has a stable internet connection. WhatsApp relies heavily on an active data connection to send and receive messages. If your device is offline or experiencing connectivity issues, the SMS verification process may fail. To resolve this, check your Wi-Fi or mobile data settings and restart your router if necessary.
Secondly, verify that your phone number is correctly entered in WhatsApp. Even a minor typo can prevent the successful delivery of the verification code. Double-check the number for accuracy and consistency with the one linked to your SIM card.
Another common reason for this error is an outdated version of WhatsApp. Developers frequently release updates that include bug fixes and performance improvements. If you haven't updated your app recently, visit the App Store or Google Play Store to download the latest version. This step can often resolve compatibility issues that might be causing the SMS failure.
In some cases, the issue may lie with your mobile carrier. Certain carriers have specific settings or restrictions that can interfere with SMS delivery. Contacting your service provider for assistance can help identify and rectify any carrier-specific problems affecting WhatsApp's functionality.
Lastly, consider the possibility of network congestion. During peak hours or in areas with high traffic, networks can become overloaded, leading to delays or failures in SMS delivery. If this is suspected, wait for a few minutes and try again later when the network might be less congested.
By systematically addressing these potential causes, you can increase the likelihood of resolving the "Failed to send SMS" error on WhatsApp and successfully complete the verification process.
