    I know GSM networks can do it 3G or LTE.

    And I thought Verizon can do it with LTE. So why won't it work?

    It works on all of the Verizon LTE phones while they are on LTE, with the exception of the iPhone 5. It's Apple's fault, not Verizon's. If I remember correctly, it's because the iPhone 5 only has two antennas and they can't be used simultaneously.

    As far as I can remember Verizon has never been able to do both & don't think sprint can either. With iPhone 5 on AT&T it switches off LTE for voice so simultaneous voice & data won't be with LTE.

    All of the Verizon LTE phones (with the exception of the iPhone 5) can do simultaneous voice and data on LTE. It's a antenna hardware limitation of the iPhone 5.

    Right. Any phone can do voice and data on WiFi. And you're right, the Sprint iPhone 5 can't do simultaneous voice and data on LTE, either. It's because it's the same hardware as the Verizon model and it's limited by the antennas. The only iPhones that can do simultaneous voice and data over cellular are the AT&T models and it works on all of them except the iPhone 2G.

    To be specific, no carrier can actually do voice over LTE at the moment, so the phone has to drop down to 3G. The reason other LTE phones can stay on LTE data while doing a phone call is that they have multiple radios, so that they can be on both 3G and LTE at the same time. There is no way to do simultaneous 3G + LTE in a single radio design.

    It is theoretically ready for Voice over LTE, though.

    Is it really dropping down to from LTE to 3G for the calls, though. I thought LTE was just for data (at least currently) and Verizon/Sprint phone calls use the 3G radio, regardless if you're using data at the time of the call or not.

    Well there is answer. It would be great to do once in a blue moon but something that I never really used much when I had AT&T so its not a big deal with me

    That capability is the only reason why I still have AT&T. My wife and I do however use it constantly and do not want to be without it.
    The downside is that we used to have very poor service where we work. But LTE just solved that problem and for the first time in years we have Great service and great connectivity.
