Some solutions when Telegram fails to send SMS

If you do not receive the confirmation code during the Telegram login process, you can follow the instructions below to fix it.

Check your network connection and login phone number

First, you need to check if your phone has an internet connection or not. If you use wifi, you need to check if the wifi is stable and strong. If you use 4G, check to see if your network subscription package still has data! Because Telegram needs a network connection to operate. If you don't have it, you definitely won't be able to log in and receive the verification code.

Next, you should check whether the phone number you logged in/registered with is correct or not? Does the SIM have signal and is it working? Sometimes the cause is not because of Telegram but because your SIM is faulty or one-way blocked, for example.
