I’ve been having an issue with your network for a while where I’m on a call and after a while the other person suddenly can’t hear me . Working out whether this is an issue with my phone , the network, or the person on the other end is what I’ve been trying to do for a while.
I have recently had a new phone and it still does it and it has happened on several calls to other people. I have full 4G signal at my house and this has been happening for a while so it’s not due to work going on. Unfortunately I am going to change network to see if that solves it . I have had WIFI calling enabled and disabled which has made no difference and due to the signal being strong it wouldn’t have been using it anyway .
The other issue is my son can't ring my Husbands phone (Sony XA2) who is also on ID Mobile from SMARTY mobile which also run on the Three network. My Husbands phone doesn't have voLTE . When my son rings it the call drops after a few seconds of ringing. If my son switches his phone to 3G only then the call will connect.
Maybe this is what the issue is with the network something to do with switching a call from 4G to 3G I don’t know.
