| T-Mobile | 124 Garden Grove Rd | Just switched from Verizon to T-Mobile. We had good coverage at home prior to the switch. We now have only 1 bar at home with delay in voice when the call does go through. Also, kept losing T-Mobile coverage on I-91 between Hartford and Springfield; calls kept cutting in and out. | 2019 |
