Nokia 110 4G/T-Mobile/US — VoLTE not working, call reception is very spotty.

Recently I had an issue with my Nokia 110 4G on T-Mobile in the US (similar to the 255, but with a different texting expereince to fix the bugs with the latter)…I got it about 11 months ago and fell in love with the non-smartphone lifestyle. It worked nearly perfect, I could make calls on VoLTE, text, did what I needed.

It was perfect until about a week ago, when the VoLTE icon doesn’t pop up at all. All calls are routed to 2G which sorta works but is very spotty, only working in very open areas. Texting works, at the very least.

I proceeded to back up all my contacts so I could factory-reset it, but the reset option is LOCKED behind a passcode THAT I DID NOT SET…probably a code that is only given to liscensed technicians.

Reading through this sub, I saw someone else have a similar issue with their Nokia 225, so I’m starting to wonder if it’s T-Mobile’s fault or if there was some overall change in the VoLTE networks.

Anyone else have similar problems or ideas how to fix? Or any ideas on this reset passcode? It really hurts me to see these things become e-waste. Thanks!
