I've got an Android LG G6 and switched to T-Mobile about 6 months ago. Frankly, I get horrible reception and I'm in a major suburb of Denver, CO. halfway between downtown and the mountains. My typical signal strength is one bar, sometimes none, sometimes two but that's it. If I drive a mile away I can get 5. There's nobody to actually talk to at T-Mobile and of course they tout "complete coverage". When I've complained online the response is you must be using your phone inside (well, duh!) or it's time for an upgrade (well, duh again!). But why the poor reception which I didn't have when I switched from AT&T? I want to upgrade, probably to a Samsung A52, but I'm concerned that reception won't improve and could get worse (impossible!!). I keep reading about T-Mobile and their push to all 4G/5G but also complaints with poor signal strength. Any thoughts? Any way to contact human tech support within TM? Do I switch to another carrier?
