I could sure use some help. Intermittently, when I make calls with my OnePlus 9 Pro, the callers can't hear me, but I can here them. I'm frustrated because I spent 90 minutes on the phone with tmob...

I had one interaction with customer service about the problem. They determined that the solution was to send an update to our SIM cards. The agent was to call back on a particular day to check on the status of the solution. They never called.
So, now I am back to trying to find a solution. If I had any confidence in C.S. I'd call them again, but was hoping this community had some information I could be armed with first.
Gracias.
I have seen a similar complaint about WiFi Calling but I haven't had any issues with WiFi Calling. What most people don't realize with WiFi Calling is, the upstream is just as important as the downstream. 20Mbit up at a minimum up is a good place to start and turning QoS off.
If it's on cellular, a new SIM might help. Are you using the SIM that came with the device? Have you tried ejecting the SIM, giving it a little bit of a clean with some Isopropyl, drying it, and putting it back in?
