I'm on a Nexus 4 with t-mobile off contract ($70/month for unlimited voice, data, and text). Service has been pretty solid, but I haven't gotten far outside of a city yet to test it. The price/no-contract part of it makes any service issues worth it for me. Service (in Denver) has been superior to what I was getting with Verizon, particularly on the data speed front.
My wife is on Virgin mobile (Sprint MVNO) and she's pretty happy with it. Pays $30/month (I think) for unlimited voice, data, and text.
