I am considering bounce w/ LTE plan for my kids. I live in rural Alaska where Tmobile (GCI) and Verizon networks work really well, but AT&T is very poor coverage (although their map indicates good coverage). I reached out to Garmin to ask what network they use, but they refused to answer my question citing that it was "proprietary information." They've advised me to go ahead and buy the watch, buy the monthly LTE service plan, and if it doesn't work return it for a refund. If it does work well, I would then be locked into the monthly plan with no chance to switch to the annual plan to enjoy the savings. They offer no trial period to verify coverage. This seems silly and a huge hassle when a simple "no it's not AT&T" would really help. So, do any users out there have any idea about this? I've read in other reviews that the bounce LTE coverage is underwhelming (especially indoors) and seems like there is a known LTE issue with *some bounce devices. Any insight would be hugely appreciated! Thank you.
