Before I lower myself into the hell that is Telco tech-support, has anyone come across this before?
Was it something that you could self-solve or was it network related?
When I'm in the area, I get weak 5G and weak 4G (1 bar) - data works great whilst attached. 3G for the most part doesn't. I can make phone calls, send SMS etc... just no data.
Sadly there is no way on the iphone 12 to force 4G only.
Restarted my phone, reset network settings and appears to impact multiple devices...no change.
