I had a Verizon sim card on Samsung Galaxy with Straight Talk service through Walmart. The GPS went out about 2 miles into the ride (MapMyRide app).... Anthony trail head riding north.
Greenbrier is the only rail trail I've had issues with GPS and service. There's parts of Creeper trail where cell service goes out...but GPS still works.
