Ultra Mobile: Plans, Coverage & Deals

Ultra Mobile is a prepaid cell phone carrier known as a mobile virtual network operator, or MVNO.

An MVNO is simply any cell phone carrier that does not operate its own cellular network.

Instead of building their own networks, MVNOs make agreements with the four big carriers to use their cellular networks for coverage.

In Ultra Mobile’s case, it uses the T-Mobile network for coverage.

If you are curious to learn more about how the agreements work between the big carriers and the small carriers, check out my article on how some cell phone plans can cost so much less than others.
