Other party cannot always hear me

I definitely understand wanting to get this working, there's no reason to stay if you can't make any calls. Did you check out our Solucionar problemas de audio en las llamadas | Asistencia de T-Mobile​? If it's still not working, you'll probably want to contáctanos over Facebook or Twitter, to make sure our Experts can fix any account issues and escalate a ticket if necessary.

This didn't solve the problem, although the problem is listed as solved.  The problem isn't that you can't hear because of volume.  The problem is that the caller here's you one moment, then you may break up, then they can't hear you at all; the call switches between these 3 intermittently. It doesn't matter if you're using the handset or the speakerphone.

I have been experiencing the same issue. Caller cannot hear me off and on throughout the call. I used earbuds, speaker on and without and the same issue.  This started happening beginning of this year and I am using an S10+. I did not have any issues prior.  I am at a loss and basically can only text people without getting frustrated when attempting to talk to them. Sad.

My husband and I are having this same problem. Both using Samsung S21. Whether we are home (wifi calling) or away (TMO network). Inconsistent timing/ location, but consistently bad. This morning we had to reconnect our call to each other 8 times in 13 minutes. It makes using voice unreliable which is unacceptable. I'm posting here hoping to read solutions. 

I have an s21 and I'm having the exact same problem. Has anyone fixed this issue? And how?  Please help! 

This has happened to both myself and my wife (S. King County WA, iPhone XI and XII).

It's becoming VERY hard to field calls. And we're supposedly in a strong signal zone.

Has this been answered I have the same issue. It's just my line. I have 3 total the other ones work fine. I'm on the verge of switching carriers

I also have a Galaxy S21. This issue started a couple of months ago and I thought it was just my wifi connection, but it happens on 4G, 5G, Wifi, you name it. I think it must be some kind of issue between Samsung devices and the TMobile network, because if I call the same person I'm having trouble speaking with via an app (like Facebook Messenger) the call goes through just fine and they can hear me just fine. So it's definitely related to the TMobile service. I also got a new SIM card a few months ago to help me connect to a nearby tower. I didn't have these issues BEFORE that SIM card upgrade. Before, I had just plain old signal issues...this is specifically JUST the microphone audio my TMobile network calls are sending. My signal is great beside that...it's like the microphone just turns off.

Count me in this club.  Galaxy s21 ultra in perfect condition.  Just started out of the blue. Maddening. Tech support has been useless.
