Anyone still using a Pixel 5 on T-Mobile? I picked one up from eBay a few months ago, and everything seemed fine at first just testing it with a prepaid SIM, but started seeing an issue using it on my postpaid line. Whenever I picked my daughter up from work, I noticed data was not working. Sometimes no data showing, and sometimes showing data but with an exclamation point next to the signal bars. That is the place I get all of the crazy fast speeds on my S21. Carrying it for a while, I started seeing it in other places too, so I doubt it had anything to do with the tower. Toggling data or airplane mode generally fixes the issue. Eventually I tried factory reset just to see if that stopped it, but it didn't. When I swapped to a TracFone AT&T sim, initially it wouldn't pick up 5G, but eventually it did, and I've never noticed a data issue with that sim in the phone, so I'm having trouble believing it's just a defective phone.
