Poor to none for over a year of workinging for better signal, though map shows 1-2. Drops and no starts / pickup + no data service... WiFi calling (last year), which added 2 year cntrct extension!) has been my solution for home use but the technology / phones supporting that type calling looks to be waning, only BB still has WiFi calling phones (with TMobile), and it had trouble switching cell to WiFi - Nokia has been great. My Magic Jack Internet phone (analogous to WiFi for cell phone) for home phone is treating me much better for ALOT less $$$ than TMobile cell phone service phones! (not that the MJ is perfect on call quality ;-) Plus it can travel with your laptop and use it anywhere internet connection exists. Won't eliminate the need for a cell phone but def reduce the price of a cell plan by cutting minutes. Looked into Sprint but with their surcharges of $25 on a $130 plan and the coverage map being fair and the reviews I see here I WON"T even try that. Was considering AT&T but the reviews for places near me and the map coverage not being excellent has me scared. I like Verizon's coverage but their plans are expensive and they like to tack on charges, be careful of the 30 day trial on both Sprint and Verizon they still want to charge something even though they say FREE for 30 days! been there done that X 2 (Verizon's Data card and a former Sprint Trio)
