We were camping this past weekend at Silver Lake State Park in Michigan. The address is 9679 W State Park Rd, Mears, MI 49436. Coverage didn't exist, and we were unable to roam on AT&T. We continually received "device not registered on network" when trying to connect to AT&T. I really didn't care about data coverage, it would be a nice to have while camping, but calls did not even work. This became a problem when a family member tried to call us and had to call the ranger station to relay a message. Anyway, we have 1 galaxy s9, a galaxy s8 international, and galaxy s8 plus, and all phones received the same message when trying to roam on AT&T. Previous to our trip I checked the tmobile coverage map and it showed fair coverage at the campground, which turned out to not be true. I am not here to grumble about tmobile, rather point this problem out as other customers may encounter this as well. Maybe I need to be patient and wait for Band 71 to get turned up in this part of Michigan, which would have only helped on my S9 anyway. Ironically, when in the Upper Peninsula this July camping we were able to roam on AT&T and complete phone calls. I even got a taste of Band 71 in the Western UP at times and it worked well.
Aside from that, I called 611 yesterday on our way home. I talked with some very nice support folks and they opened a ticket. I received a text message last night that the problem was resolved, but I don't think it is.
My question is, can anything further be done to help with this situation, or others who experience it?
