Wow, that's suboptimal. It used to be, you only needed a phone that could receive an SMS to verify your phone number. I guess those days are over.
I tried that several times at first, but it never worked. I also contacted support, but they never responded. On the bright side, the process isn't too bad:
Insert your SIM card into any Android or iOS phone that has the Telegram app installed
If someone else is already logged in on the phone, log them out
Create and verify your account on the phone
While still logged in on the phone, initiate login process on any Telegram desktop app
Use logged in account on phone to verify login attempt from desktop app (QR code, verification code via Telegram message)
Log out on the phone, remove your SIM card, put other person's SIM card back in, etc.
Done. As long as you always have at least one active, valid session on any device, you can use it to verify other devices and never need the phone again.
