Since about 3 days ago neither me or my wife are able to make or receive voice calls on our mobiles. Data works fine as does SMS. She is on iPhone, I am on android. I've power cycled phones, gone through network stuff. When I try to make a call it's just silent then times out after a minute.
Thanks David. Yes we knew 3g was being shut down but didn't realize that the nature of voice calls would change. I've enabled voLte on the iPhone and it's working now. Unfortunately my OnePlus 5 is doomed (unless I do the fandnangling that some folks suggest might enable it).
