Could not get 4G connection in Grand Lake CO- my phone kept trying to connect to a t-mobile signal. Had to find wireless internet at a coffeeshop to check in. I understand lack of of signal in the mountains, but not in town. Thoughts?
The whole area around is shown as Partner Coverage, so it doesn't look like AT&T has any towers out there. Unfortunately not all services may be available when your phone is roaming on another carrier's networks. In some cases, voice and text are fine but data might be on frequency that your phone might not support, especially with 4G and LTE devices.
