Follow these steps to recover your Telegram account:
- This process should be done on a desktop, it is going to be easier and more practical.
- Open Telegram in your web browser and try to log into your account regularly, using your phone number, like you always do.
- Now, you will see a new message appear on your computer’s screen telling you that they have sent a confirmation code to your phone and asking you to enter that code in the selected field. Since you have your new SIM card that will not be a problem for you, just enter the code and click on the login button.
