The piece on Best T-Mobile MVNOs is outdated and inaccurate with regards to US Mobile. The essay suggests US Mobile only offers T-Mobile and Verizon. Not so. They also offer AT&T service. The 3 networks are named Warp (VZN), Light Speed (T-MO) and Dark Star (AT&T). The naming of AT&T’s service as Dark Star seems appropriate, given the troubles they’ve been having lately. They need a new CEO. But, Clark’s team needs to update they essay on US Mobile and the services it offers.
