Hello everyone, I've been having a frustrating problem on my phone for some time now, and T-Mobile doesn't seem to know what's going on or is unwilling to help. I have an OnePlus 6T (bought from OnePlus) running on the Tmobile network, and it has been receiving delayed texts (sometimes up to 12 hours!) as well as missing important incoming calls. The problem started on my previous phone (OnePlus 3T), and I thought getting a new one would fix the problem, but so far the problem still persists. I've tried....
-Getting a new SIM card
-Clearing my phone cache
-Refreshing network settings
-Having T-Mobile refresh the network from their end
-Updated APN settings
The issue occurs daily, and only occurs with incoming texts and calls, no problem with outgoing. I've been tracking timestamps for my texts and it can delayed anywhere from 5 minutes to 12 hours, sometimes even more. I text my own number occasionally and sometimes that also gets delayed as well. When I restart my phone, everything works fine and dandy, but a few hours later the same thing keeps happening. And thats the most frustrating part because whenever I talk to T-Mobile and they refresh my device and the network, they'll say that it's working now and the device is working again, but the problem keeps happening a few hours later.
I'm on a family plan, and my number is the only one having this issue. My mother and sister have the same phone and don't have any issues. I've also tried using a branded T-mobile phone and I'm still having the same problem!
