    I'm having a problem with my Oneplus 6T where the sim card kept on disconnecting when I'm at home. This also affect my mobile data and calls at the same time where it will just break off.

    I even did a warrently on the phone for a replacement and still having the same problem.

    This seems to be an ongoing issue in certain areas with T-Mobile. It's very isolated right now, but am fearful it'll get worse. Speculation is that it has to do with their 5G rollout, which must be doing something that causes the radios in the 6T to crash/reset, which is causing them to disconnect:


    If it's easily reproducible for you, I'd submit a bug report here and get some debug logs into OnePlus's hands ASAP.

    It could be anything (slightly incompatible software stacks between vendors, etc.) -- especially given that so much is changing on the back end systems (new bands, new protocols, etc.)

    Ranting in a forum isn't going to fix the problem. File a bug report -- that'll help! I'd recommend that you do the same with T-Mobile, but they are far less accessible than OnePlus with respect to reporting problems. Report the bug and let OnePlus and T-Mobile figure it out.
