Callers can't hear me!!

Most of the calls, the callers can NOT hear me BUT, most of the time I can hear them.
Also, when I callback, again they can NOT hear me.

VOIP calls are perfect, with voice crystal on both sides!


The device is Lenovo K6 Power and the device is good, as it was working fine with earlier telecom service!

So, what is happening here?


Please help!

I’m having the same issue. I can hear people just fine but they can’t hear me. Sometimes I can have 5 minutes with a signal and all is good. Then loose the ability for others to hear me. Other times it’s like this all the time. 
 Samsung 9 upgraded to Samsung 21. Also have an iPhone 11 Pro. All have this issue. It started about 6 months ago seems to be related to the tower in my area. When I go out of town there is no issues.

Has there been any resolution on this issue?


Hey did this issue get fixed, I am having this same issue it is not the device as it is happening with all my family that is on the same t-mobile plan and we all have different types of phones, I also have two co-workers that have t-mobile and have the same issue some times rebooting the phones fixes it sometimes not.


I bought a new Xiaomi 10 pro, I am having the same problem!!!! I find for xiao mi 10 pro . input *#*#86583#*#*. you can see “Volte carrier check was disabled” then you can enable and disable volte. It should be helpful!~

I’m definitely having this same issue (among others).   I have a Moto G7 that was purchased in September 2019.   I already have issues where I can’t take a call in the basement because sound quality on both ends are terrible.   But in the last month I’ve run into situations where I can hear the caller loud and clear but when I attempt to respond they say they can’t hear me.   I try to move around to see if it helps and it’s hit or miss.

I notice too when I talk to my Dad (who also has a T-Mobile phone), both of us have issues with hearing each other.   I’ll notice on my end that the sound goes in and out.   

I did read in the thread about a SIM card replacement.   I may have to try that but am open to other suggestions.   

It took me a long time to figure this out - but the issue was the "VoLTE" setting in "Mobile Data".  Every call I would receive would basically act like two calls.  And because of that, callers couldnt hear me, and the number pad in calls wouldnt work.  There was also huge lag answering and hanging up on calls.  After clicking "Accept" in the banner when a call came in, i would then be presented with the swipe up or down option for accepting the same call - even though the call was already received.

In any case - turning off VoLTE fixed the problem.

Is your phone still under warranty?  If it has been less than a year since you purchased the phone, you should still be covered under Apple's manufacturer warranty and you can take your device to an Apple store and have them take a peek.  They will either repair or replace the device as long as there is no physical damage or moisture exposure.  If it is beyond a year, and you have insurance on the phone (which includes an extended warranty) you can look at getting a replacement through T-Mobile, but they will likely want you to perform some troubleshooting that may include a full backup and restore of the phone before an exchange can be performed.

I’m having this same issue! I went in and had my SIM card changed, nothing was fixed. I’m using an iPhone 8 Plus.

Calls work perfectly using FaceTime Audio. But when i call or someone calls me, they either can’t hear me or hear tech/static sounds.

Recently, no one can hear me at all.

What can we do about this?

Ok, will do that, thanks.

Oh okay! In that case, we would need to set up a buyers remorse exchange. You can go to the store and purchase another phone and send back your current one within the 20 day time frame or you can contact us and we can send you out the replacement.

I just got it 5 days ago. Online via

Well that is interesting. With the way it was behaving, I wouldn't think it to be a hard ware issue. How long ago did you get your phone? Did you get it a at T-Mobile store?

I am having the same problems outdoors as well and in different areas. I believe its my microphone on my phone. I will be taking the phone back for an exchange.

Hey @magenta4819046

I just replied to you here Re: I make a call but they can't hear me although i can hear them

I am having the same problem with my LG V30.  It's random and doesn't always have the problem. I just got my phone 3 days ago. I never had this problem with my other phone which was a samsung.  Not sure if the issue is with the phone or in the area.

Ah okay. I'm a little bummed you were having the trouble using our SIM but at least you don't have to deal with all the issues. So, I'm happy for you. Thanks for keeping us posted. 😊

I did test this with a H2O SIM card and 'voila' it fixed all my issues. No call drops, the other side can hear me loud and clear, and to top it all, now am on high speed data. It is just $30/- per month. Hope, it stays this way! 😀

Thanks all for your support! 😊

Hey again. Just curious if you've tested another SIM card. If so, we'd like to know if that did the trick and fixed the issue. Please let us know. Thanks!

Ah okay. Changing the SIM could help. I've seen it work before. If you do change it, please let us know if that fixes the issue.

At this time, I couldn't bring myself to buy a new phone. I might go for a new SIM.

Thanks for your time! 😊

Hey there and sorry to hear the reset didn't help out. I totally agree with Chris about using a T-Mobile branded device. Have you thought about that as an option? Please let us know what you decide to do.

Userlevel 4

Yikes, okay, I am thinking that it is going to be a compatibility issue at this point and it might be best to look into upgrading your device. We would hate to lose your business but I do believe getting a T-Mobile branded phone is going to be our best option here.

Nah! No luck as of now. Did a full reset, BUT still the same issues! 😢

Hey there! Any luck with the cache wipe or master reset?

Okay. I was just trying to think of other things that could be the cause. I mean, you could try wiping the cache, but ultimately the reset would be the last option.

AFAIK, NO moisture or heavy drops!

I don't know what else to do.. might try a hard reset and that's it.
