problem with iphone7 plus dropping calls

Be sure you don't have something interfering with the iPhone's antennae (like a case).

Once you've done that, if you still have an issue, contact your cellular carrier.

Iphone 7 here dropping calls after 30sec, when calling Facetime calls you can´t hear anything but hissing but they can hear your voice.

I'm having issue with the call on iPhone7 (ios 10.0.2). After few minutes being on the call, the call goes silent. I have end the call and ring again..!!

Me too!

I can hear them, but they can't hear me. Sometimes it already happens after 30 seconds :-/

The problem started with iOS 10.0.2. (I think)

Yes the exact same problem.... I'm not impressed by the iPhone7.
