No GSM coverage but has LTE coverage?

I was on a trip to Yosemite, and along the highway, I realized there was no GSM network coverage.  I then realized there was LTE coverage, as once I enabled Cell Data usage, I was able to make an LTE call.

Why was GSM coverage not available but LTE available in some areas?  I thought GSM is always available as long as there's good signal?

Hey, @memn1​!

I'm glad you were able to connect to LTE. As for why you weren't able to get on our 2G/3G network can depend on a few things such as your phone type and compatibility with the frequencies provided or towers may have been undergoing maintenance. I looked over the area and see that a new tower that includes 2G is being added to the area but we also have our U1900 and LTE 2100 bands active in the area.
