    Why can't I talk on the phone and surf the net at the same time. I know I can using WiFi but I can't using only the Verizon network.

    Why can't I talk on the phone and surf the net at the same time. I know I can using WiFi but I can't using only the Verizon network.
    The reason below is why.


    GSM Carriers (AT&T / T-Mobile) – Both can use voice and data at the same. Either on HSPA or on LTE (using VoLTE).

    CDMA Carriers (Sprint / Verizon) – These carriers can only handle voice or data. Not both at the same time… Unless using VoLTE. Verizon currently has VoLTE whereas Sprint doesn’t. You may be asking – why is this? My old phone did this... which I am sure it did. A longer explanation is below.


    [INFO]The older phones had two CDMA radios put in them (such as the S3 on Sprint). One dedicated to voice -- another dedicated to data. Therefore you could do voice and data. GSM has always been one radio because that one radio can do both tasks at the same time. They got around it on CDMA by simply adding another radio in there and dedicating each one to one task.

    Now they're getting rid of that second CDMA radio. So therefore you can only use talk, or data -- not both at the same time. Now if you're using VoLTE for your calls it will allow voice and data since the call will be going through LTE (as data) so it is technically then all data which would bypass this restriction.[/INFO]
