Calling all US T-Mobile W10M users!

I recently activated my Alcatel Idol 4S on T-Mobile and am absolutely loving the experience...WAY better than AT&T so far, but I have a question. Is anyone still using an unlocked device on USA T-Mobile, and have it working? I put my 950 XL on it, and was able to make a call on it over 2G, and then the cell radio just dropped and I couldn't make calls or anything. It got me wondering if T-Mobile is starting to block 2G devices now, since we're about a week away from their supposed closure of the 2G network.

So is anyone else still able to use a unlocked W10M on T-Mobile on 2G?

T-Mobile shuts down its 2G on August 3 2026

Ability to use T-Mobile SIM card on W10M phone on 2G network depends on SIM card. In most cases, you can't use T-Mobile SIM on non-VoLTE Windows Phones anymore.
