Cell phones from nearly every manufacturer will work on our network as long as they are 4G VoLTE or 5G compatible and use a SIM card. If you already have a compatible phone, all you need to do is purchase an Ultra Mobile SIM kit.

If your 4G VoLTE or 5G compatible phone meets the following two criteria, your phone will work with Ultra Mobile:

1. Your phone requires a SIM card.
2. You have an unlocked phone.

If you begin your Ultra Mobile registration and your phone says, “Restricted” or “Contact Service Provider,” doesn’t allow you to make calls, or won’t grant access to your phone book, the phone is most likely locked. Contact your previous carrier to unlock your phone.
