unable to make or receive phone calls
I have an old Galaxy J7 phone. Recently (and very suddenly), it has twice lost the ability to make or receive calls. However, I can still send and receive text messages. The first occurrence lasted for a day. I left the phone sitting with the battery removed overnight, and it started working normally the next day. T-Mobile's on line support's solution was to replace my antiquated phone. That may very well be necessary, but I want to exhaust other possible causes first. Could a defective SIM card be causing this issue?
It's more than likely the device itself. The band support for that device doesn't include a lot of bands T-Mobile is using currently and as network upgrades make their way across the nation. You are going to see more and more of these older devices lose connectivity to the T-Mobile network.
