my steam authenticator is on my old phone, and it is seriously broken now and I cannot turn on wifi on my old phone, and even when I contact steam support to try to get some help by using my new phone with the old phone number that I used to log in along with steam, but there was no message to my SMS, what should I do now?

Help! I sold or lost my phone and I can't log in anymore! What do I do?

If possible, you should contact your wireless service provider and get a replacement phone with the same phone number. Steam will be able to send SMS messages to your replacement phone, and you will be able to recover your account as described below.

If you no longer have access to your phone and don't have your recovery code, you'll need the assistance of Steam Support. Use the "Help me with my issue" button at the top right of this page to get help removing your authenticator. If you don’t have access to the email address that is currently associated with your Steam Account please provide proof of account ownership within your ticket.
