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.
