I have 3 phones...
They were
FirstNet/AT&T
Verizon
Cricket Wireless
Now they're
FirstNet ATT
VTe-Mobile
Cricket wireless
Verizon was worthless. I didn't get coverage until almost into Winchester so it ran off of the Hotspot of my ATT phones.
Then the Verizon phone was swapped with a T-mobile. I figured it would be equally as bad
I'm actually surprised at the coverage of T-Mobile.
I'll test it down Lost River valley.. or up towards Paw Paw. that's usually 2 hours of driving with no coverage
