How to view carrier lock status to verify if iPhone is unlocked

Learn how to view carrier information on your iPhone to confirm whether the device you’re buying or selling is locked or unlocked.

You can prove to a potential buyer that your iPhone is unlocked by pulling out your SIM card and inserting theirs.

An even easier approach (especially for those with eSIM-only models) is to view carrier lock information in the Settings app to quickly verify if the device is locked to a specific carrier or unlocked for use on any compatible wireless network.

1. Open the Settings app on your iPhone.
2. Tap General.
3. Select About.
4. If you see “No SIM restrictions” next to Carrier Lock, the device is unlocked and not tied to a particular carrier like AT&T, T-Mobile, or Verizon.

Conversely, a different Carrier Lock message could mean your phone is locked, so it cannot be used on other carriers’ networks. An unlocked iPhone can be used on all major US carriers.
