US Mobile operates over all three of the major US networksβAT&T, Verizon, and T-Mobile. US Mobile uses a branded word or phrase to refer to each service:
US Mobile subscribers choose any one network for their service to run over. While subscribers can't access multiple networks simultaneously, US Mobile allows subscribers to switch networks relatively easily.
US Mobile typically tracks users onto its Dark Star service. However, some subscribers argue the Warp service is more mature and feature rich.
While AT&T (Dark Star) and Verizon (Warp) have larger networks than T-Mobile (Light Speed), coverage quality is highly dependent on location. Explore the coverage map to get a feel for how the different US Mobile services may perform in your area.
