Why can't I use data during calls on my S6?

Why can't I use data during a phone call anymore? It goes to 1x . Is this the way it is on the S6  or can I change something. even my S3  and S4  could do both

You need to turn on Advanced Calling (HD Voice) in your Verizon account  and make sure VoLTE is turned on in phone settings.  You also need to be in an LTE area.  Then you will have simultaneous voice and data.

OK thank you I'll try that. And yes I'm in 4gLTE  right now

That was the problem. Thanks a bunch. I was fixing to trade it back in and get the S5.  Your my hero of the day thanks again

I have turned on advanced calling and switched from global to LTE/CDMA and still can't use data when making a call. What the hell is the point of upgrading to a new phone that doesn't do simple things my old clunky DNA did? When ever I get a call or make a call the darn thing kicks over to 1x and turns off data. This is a huge issue.

You must turn on VoLTE or LTE calling also. That is going to be in a different area of your android phone. I am iPhone only, so you'll have to wait for an android person to show up if you can't find it. But that is what you need to do.

2 parameters

Advanced Calling turned on in your account online

and

LTE calling or VoLTE turned on the phone.

I have been into every dang menu on this phone I have not seen volte or let calling. I have HD calling turned on. The network is set to LTE/CDMA. This is the dumbest thing ever. What is the point in buying a brand new phone if they are going to make you use old out dated technology?

For some reason when I tested it last night it wasn't working. For some reason without changing anything it started working today.

mmaybe Verizon didn't turn your line on in the backend.  Enjoy modern form of voice and data!
