Ultra Mobile provides budget-friendly prepaid plans powered by T-Mobile's 4G LTE and 5G wireless coverage.

As a Mobile Virtual Network Operator (MVNO), this low-cost carrier can save you up to $600 per year on your cell phone plan.

Follow these simple steps to get started:

1: Check Ultra Mobile coverage

Ensuring network coverage in your area is crucial before signing up for an Ultra Mobile plan. Enter your ZIP code into our Ultra Mobile coverage map to confirm availability. This step is essential if you haven't used T-Mobile's network before.


2: Bring your own phone to Ultra Mobile

Once you confirm network coverage where you live, you can decide whether to bring your own phone to Ultra Mobile or buy a new device.

By bringing your unlocked compatible phone, you can enjoy more savings. Or, if you prefer, a diverse range of Ultra Mobile phones are available for purchase, with phone financing available.
