Mic stops working during cellular calls after few minutes.

For the past few weeks, when I am on a call, the other person stops hearing me after about 2 to 3 mins into the call. This does not happen during Whatsapp calls, only happens on cellular calls. I have a Samsung S8 plus with H2O WIRELESS service. Please help as I am going crazy!

Welcome to Android Central! Does this happen with every call, or only occasionally? Have you asked H2O about it?

Also, see if the problem persists in Safe Mode, in case there's a 3rd party app that's causing the interference: https://support.t-mobile.com/docs/DOC-34283

I have precisely the same problem with my Galaxy J5 (2017 - SM-J530F) running stock Android 9.
It is consistent throughout all inbound mobile calls, whether from a landline or mobile.
Within 2-3 minutes the other party cannot hear me at all.
Use of the speakerphone does not affect the problem at all.
Yet use of wifi to make/receive calls via Whatsapp/Messenger/whatever is perfect.

Any suggestions will be very welcome - before I throw this phone through the window !!

Thank you.
