If you’re thinking of purchasing a used iPhone and you want to be sure that it’s unlocked or if it will work on your carrier (AT&T uses GSM and Verizon uses CDMA), you’ll be pleased to know that there’s a quick and easy way to find out in iOS 14.
There’s no need to call any carriers or swap out any SIM cards. Just take a quick dive into the Settings app and you’ll find all the information you need. We’ll show you how.
If you’re buying a used iPhone that’s running iOS 13 or earlier, the easiest way to check that it’s going to be compatible with your carrier is by putting your SIM card inside it and ensuring it connects.
Of course, that’s fiddly and time-consuming, and some stores and private sellers may not be happy with you doing that until you’ve actually paid for the device. Fortunately, it’s easier in iOS 14.
Apple now provides this information in the Settings app on both iPhone and iPad (those with cellular connections, at least). Follow these steps to find it:
“No SIM restrictions” means that the iPhone or iPad you’re using is completely unlocked, and will accept any SIM card. If you see anything else in this box, it likely means the device is locked to a certain carrier.
