With this advanced calling you are forced to keep it on in order to surf the Web during a phone call. I previouslyrics had an S4 which I was able to make phone calls during a phone call.
Now, I recently had my advanced calling on but forgot to turn on my mobile data while on a phone call you are locked out trying to turn your mobile data on. This is the sad part about advanced calling HD. This made me regret selling my S4. I wonder if I should purchased international phone instead.
I believe advance calling or VOLTE should be an optional setting and that surfing and talking on the phone should be done without having the VoLTE on. I really hope verizon can release an update on there network allow surfing the Web during a call without the advanced calling features.
