I've been using T-Mobile since I got here in 2016 and coverage has expanded way more than it was back then, I used to basically have zero coverage outside of Burlington, some of St Albans, and Montpelier, and a few other small areas, but I can get a consistent signal through most highways and small towns now. I still get plenty of deadzones, but my gf has Verizon and she used to get coverage way more than I did, and now it's literally the opposite.
