Samsung Note 20 5G, says 4GLTE 1 bar currently
At work I can usually make calls and 50% time send or receive texts. I cannot send or rcv any pic texts or connect to any internet with mobile data. Office has no wifi. Please help. I pay for this service and cannot use it 40+ hours per week. AT&T works for my coworkers so I may have to switch.
Edit: not prepay service, zip is 70754
