I went to Knoxville, TN for Thanksgiving today and brought my 4s with me and it’s getting 2 bars average. Is it supposed to still get service? Before when I made calls it would fail, but now it calls American Roaming. It’s a Verizon phone with an old SIM card, but it still gets a few bars when I take the SIM card out. Anyone know why? Verizon’s 3g networks shut down a while ago.
It looks like US Cellular covers Knoxville. They still have CDMA 3G operating, and will be shutting it down January 2024. Very likely your phone is connecting to them because it’s the only network it can find.
I just checked the coverage map and I’m going back home today and where I live only 4g is supported
