The fastest way to check is our online compatibility checker. Enter your phone's IMEI number and we'll tell you if it works. iPhone 14 and later models sold in the U.S. use eSIM only.
Check your phone
1. Go to the Optimum Mobile compatibility checker.
2. Enter your phone's IMEI number.
3. Follow the results on screen.
If something goes wrong
- Your phone supports eSIM? We'll set it up with eSIM. We recommend eSIM where your phone supports it. Need a physical SIM? Choose it when you buy, even online. Or get one later from Care or an Optimum store.
- Older models that support eSIM include iPhone XR, XS, 11, 12, 13, and SE (2nd and 3rd generation). They also include Samsung Galaxy S20, S21, S22, Note 20, Z Flip3, Z Flip4, Z Fold3, and Z Fold4. This list isn't complete, so always use the checker.
