This is so bad. Mtn calls to mtn is zero voice from both ends, ie the caller and the reciever won't hear themselves. While mtn to other network allows you to her the other network but they will not hear you. No massage from the service provider on this development.

Is anybody experiencing this, before I will accuse my phone of wrong doing?

Yes...experience same ds night

Experiencing same issue and I actually thought it was my phone....opened it,turned it off/on all same....until a friend told me it's happening to him too....if it's free data now they won't give me ...but rubbish like this...am the first
