Network Coverage Ultra Mobile USA

Ultra Mobile

Ultra Mobile also uses the T-Mobile network and has very good coverage along the coasts or urbanized areas. If you’re driving cross-country in an RV or hitting up the national parks, resort to a card that uses the AT&T network instead. Ultra Mobile and Simple Mobile do have the advantage, albeit not largest in coverage area, that they offer a ton of data and calling credit to international numbers. Ultra Mobile calls itself ‘the’ carrier for travelers and offers excellent data speeds, especially on the East and the West coast.
