I have T-Mobile which is great in Birmingham, Alabama but started having spotty coverage as we travelled North. No problems in NJ (08759) bit I started losing coverage and calls began dropping once we reached I-87 (13030) and became steadilly worse once we got into the New York State Thruway (12136) and disappeared once I turned onto NY-22 (01266). I had no coverage in Williamstown, Ma (01267) nor at the Walmart in Bennington, VT (01247). I am having my son poll the students at Williams to see which plan they have so I can switch. Most of them have an Iphone which means AT&T, which I HATE, but I have to have coverage. The reception on the calls from Birmingham to Williamstown is also not great.
