Our take
4G networks transformed our internet experience with faster speeds and better connectivity, and 5G is now taking this further with even quicker speeds. Although 5G is becoming more common, it remains relatively new and not universally available. Networks offering 5G can be costly and might not always match the features of 4G networks.
US Mobile provides 5G mobile data connectivity in the US, claiming to reach speeds of up to 3GB p/s through eSIMs that can be activated remotely. The company offers a range of plans from cheap "talk and text" to unlimited data packages, the latter of which comes with a variety of perks such as free streaming service subscriptions and free international calls.
Whilst the company will face competition from the growing number of 5G network providers, US Mobile stands out by focusing on providing access to all, from unlimited family 3GB p/s packages to individual basic text and call SIMs. The company also guarantees full US coverage, in addition to providing various group pool packages for families and businesses - features which should see it remain a strong option in the market.
