How can I access my Telegram if my old phone number is deactivated?

Due to some tech issues, I wasn’t able to register the SIM and phone number linked to my Telegram account, and now both are deactivated. Before I could change the number on my Telegram account, my phone died. I have a new SIM and phone number (and a new phone), and I’m hoping to access my account. Is there any way to recover it?

Unfortunately, no—unless you have another device that’s still logged into the Telegram account you’re trying to access.

You can’t. To prevent this in the future, try adding another device like a laptop. As long as that session stays active, it can receive recovery codes.
