How do I switch phones from AT&T to Spectrum Mobile?
Answer
This is a number port, not a phone repair. Confirm the AT&T account can release the numbers, gather the port-out details Spectrum asks for, then start the transfer with Spectrum while the phones are ready to activate.
Before you start: stop right away if…
- Do not share AT&T or Spectrum passwords, PINs, or one-time codes with anyone who contacts you unexpectedly.
Follow these steps
Check AT&T account status
Sign in to the official AT&T account for the lines and confirm whether each number can still be ported out. Note any past-due balance or final bill requirements that could block a transfer.
You should see: You know whether AT&T is ready to release the numbers.
Collect Spectrum port-out details
Gather the account holder name, billing address, AT&T account number, and port-out PIN or passcode exactly as Spectrum’s activation flow requests.
You should see: You have the port details ready before starting Spectrum activation.
Confirm phone compatibility
On each phone, open the About phone or device info screen and confirm the model is unlocked or listed as compatible with Spectrum Mobile before you begin the transfer.
You should see: You know which phones can move as-is and which may need a different device or SIM/eSIM plan.
Start the Spectrum transfer
Begin activation or number transfer in the official Spectrum Mobile process, enter the AT&T port-out details carefully, and keep the phones nearby to finish SIM or eSIM setup.
You should see: Spectrum accepts the port request and the phones move toward active service on Spectrum.

Extra tips
What to look for: AT&T account status for each line, the account number and port-out PIN Spectrum requests, and whether each phone is unlocked or Spectrum-compatible.
Before you change anything: Write down each phone number you want to keep. Confirm you can sign in to the AT&T account that owns the lines. Check whether each phone is unlocked and compatible with Spectrum Mobile. Never share account passwords or one-time codes with unexpected callers.
