I first heard from a T-Mobile employee. I confirmed it online. 2G is already off in some areas, 3G is slated to be turned off, probably by the end of this year or next--I forget exactly. I just know that at some point I wall have to buy a phone that will not last as long as my current one has.
Crazy. I remember when they sunsetted tdma and amps. Those were different systems though. GSM is the baseline for hsdpa and lte. They shouldn't need to do anything to maintain backwards compatibility. I could see a CDMA company that transitioned to lte sunsetting CDMA and CDMA rv.1 but I don't know why they would need to shut down older GSM tech. I havent done that kind of work in a while though so maybe I'm missing something.
I guess I should post for all: https://www.digi.com/blog/post/2g-3g-4g-lte-network-shutdown-updates
Ah to shuffle bandwidth NOW it makes sense. Thanks for the link I couldn't for the life of me figure out why they would need to (in previous sunsets it was because old systems ran on completely different hardware). Now I understand.
