How to Check if My iPhone Is Unlocked is straightforward once you use the current iPhone controls. The exact wording can vary slightly by iOS version, carrier, and iPhone model.
- Open Settings > General > About.
- Find Carrier Lock.
- If it says No SIM restrictions, the iPhone is carrier-unlocked. Other wording can indicate that it remains restricted.
A carrier unlock is different from the screen passcode, Activation Lock, or an Apple Account lock.
Before making the change, make sure the iPhone is running a current iOS release and that you know any passcode, Apple Account, carrier, or app credentials the feature may require. If the labels on your screen do not exactly match these steps, use Settings search to find the named feature rather than choosing a similarly named control. Apple occasionally moves settings between iOS releases.
