How do I restore AT&T phone service after an account was closed while another line still works?
Answer
Only the account holder or authorized user can usually reopen or move lines after an AT&T account is closed. Gather the account details and the working line’s number, then use official AT&T support or a store to restore or reactivate the out-of-service line.
Before you start: stop right away if…
- Avoid third-party sites that promise to restore carrier service for an upfront fee outside AT&T.
Follow these steps
Confirm which lines are active
Sign in to the official AT&T account page or app with the account used for billing and list which numbers show as active, suspended, or canceled.
You should see: You can see the status of the working line and the line that needs service.
Verify account ownership details
Have the account holder name, billing address, last bill amount or payment method, and account PIN ready before contacting support so AT&T can verify you.
You should see: You pass AT&T’s identity checks as the owner or authorized user.
Ask to restore or reopen the disconnected line
Through AT&T support or a store, request reactivation of the out-of-service number on the active account, or ask what is required if the number was released or ported.
You should see: AT&T either restores the number, assigns a replacement line, or explains why the old number cannot return.
Test the phone after reactivation
Insert or re-enable the SIM/eSIM for the restored line, restart the phone, and place a test call and data session.
You should see: The restored line can call, text, and use mobile data again.

Extra tips
What to look for: Whether AT&T says the line was closed, suspended, or ported away, and whether your name is listed as the account owner or authorized user.
Before you change anything: Collect the account holder name, billing address, the working phone number, and the number that lost service. Note the approximate date service stopped. Use AT&T’s official app, website, phone support, or retail store—not third-party “restore service” links. Do not share full account PINs or one-time codes with unexpected callers.
