I can't receive the telegram message on my mobile phone.

Your mobile phone can't receive SMS verification message from Telegram. You can try the following steps to solve the problem:

1. Make sure the mobile phone number is correct: check whether the mobile phone number you entered when you registered the Telegram is correct, including the country code and the mobile phone number itself.

2. Check the network connection: make sure that the mobile phone is in a good network connection state. You can try switching to other networks, such as Wi-Fi or data networks, and see if there is any difference.

3. Check SMS inbox or spam: Check whether there is a verification telegram in your SMS inbox or spam folder. Sometimes short messages may be wrongly classified as spam.

4. Wait a while: Sometimes, due to communication delay or operator problems, short messages may take longer to arrive. It is recommended to wait patiently for a while to see if you will receive a text message.

5. Select voice phone verification: On the verification page of telegram and short message, you can select voice phone to receive verification code. Telegram is a cross-platform instant messaging application that allows users to send messages, make voice calls and share media files.
