See if you can get a loaner phone for a few days and test Tmoble coverage. I had att for years switched to tmoble and it didn't work at the farm so we had to bail out and it cost us to get out of the service. Have att again but now a hired man got tmoble cause verison was costing him too much he said. Well now he has no service once he leaves the fargo nd moorhead mn area and goes to my farm 25 miles from town. He can make a call once and a while but can only hear every other word
