Samsung Galaxy A52 5G refuses to use mobile data

Took everything I was going to say and complain about. Phone does not connect to the network. Light blue Airplane mode. I called Samsung and Tmobile and they have no answers other than to reset settings. I also did the factory reset. The light blue mode went away but still no network settings. I also suspect this was a planned failure. Every Samsung phone I have ever owned failed after 2 years. EVERY SINGLE ONE. Expensive phones. Budget phones. Doesn’t matter. This is also Samsung’s last draw with me as far as phones go. I am playing with riskier fixes now such as custom OS downloads and the reboot menu to see if I can force it back on the network. The phone is useless anyways so I might as well try. The OnePlus N200 is out for $300 and I might try them. The only difference from the A52 is a loss of 2GB of ram which is significant but better than spending $700 on a phone from big tech, Google, Apple, Samsung. It’s a Chinese brand which I’m a little iffy about as is TCL but at this point what else can I do. All of the makers as far as I’m concerned all of them have sketchy reputations. I switched the SIM card into a 3 year old off brand phone no longer made, that still works as a temporary solution.  Good Luck
