We also use US Mobile, works really well and we are paying $34/month for 3 lines total...My wife and I were on T-Mobile and the cost compared to a good MVNO is just too much. US Mobile offers both Verizon and T-Mobile plans and it's half the price we were paying for the three lines (one "free" line) we had with them at around $145/month. IMO, the cost savings of switching is well worth it if you're not upgrading year over year.
