When using the US Cell Phone Plan, it’s important to note that T-Mobile’s coverage is generally strong in urban and highly populated areas. The carrier’s 4G and 3G networks claim to cover 99% of Americans, focusing on cities and medium to large population centers.

However, coverage can be weaker in rural regions, particularly in parts of the Midwest and West Coast.
