Telgram cannot receive SMS verification code.

According to the inquiry of Telegram official website, Telegram cannot receive the SMS verification code, which may be caused by the following reasons:

1. Your network is not open properly or the server can't connect, which makes it impossible to access the telegraph server. You can visit the official website address of the Telegram in the browser to see if it is opened normally.

2. Your mobile phone operator blocked the telegraph SMS verification service, which made it impossible to receive the verification code. You can ask whether the telecom operator has opened the international short message service or registered with other mobile phone numbers. You can also consider buying an overseas virtual mobile phone number, such as Google Voice, and registering a telegraph account.

3. The IP address you used was recognized as high risk by Telegram, which made it impossible to trigger SMS verification. You can switch IP addresses or nodes and try to re-register. This situation generally only affects the reception of verification code, and has no more influence on daily use.
