When you want to keep a work or community account separate from your personal number, you can verify Telegram with a one-time virtual number. Follow the steps below and you are done in about five minutes.
An AllinSMS account (created with a single token) and enough balance for one number. Install the Telegram app or desktop client beforehand.
A one-time number cannot receive codes later. In Telegram, open Privacy and Security and set a two-step verification password and a recovery email. That keeps your account safe without the number.
If no code arrives in time, you get a full automatic refund. Pick another country and try again. Switching to a country with plenty of stock is usually faster than retrying the same one.
Paste your account token to sign in.
