Is there any cell service up there? I have VZW and TMO. Does anyone know if either of those will work? Need to know if I'll be able to get an Uber (so also need GPS).

No cell service but you can order Uber through WiFi. I do it regularly.

No service with AT&T either.

I did not get service with T-Mobile but the wifi worked fine.

My Verizon did not get service. They also have a courtesy land line.

I had no service there with t-mobile. They do have wifi though.

Wi-Fi will get you an Uber

I have Sprint, and had little reception. I would not rely on the cell service up the canyon!
