Signal Issues and Call Dropping since IOS 13 update.

I recently updated my Iphone 8 to IOS 13 and subsequently to IOS 13.1.2.


When I make or receive calls, the calls get dropped/cut off constantly.  Some clients noted that when they try to call me my phone just beeps as if it is off even though that is not the case.


Something seems to be very wrong with the signal since updating. I am on Vodacom's network in South Africa. Can anyone please confirm whether this is a known current issue?

Dear all


I have managed to get a solution to this matter, or so it seems.


Go to settings - Cellular - Cellular Data Options - Voice and Data. The selected option should be changed to "4G, VoLTE off".


Hope this helps.
