    Is anyone else getting voice and data simultaneously on their sprint models? I've been noticing it for a few days now. Of course when I go to areas with a bad signal it doesn't work but in strong areas it comes through while I'm on calls.

    It's hard to find any concrete information about this. Sprint finally soft-launched VoLTE last fall (https://s4gru.com/entry/432-sprint-t...-in-september/), but their main information page still says it's available in "selected areas," without being more specific (www.sprint.com/en/shop/services/volte.html). Calling Sprint's customer service might give you more current information, but then again, the agents might not have a clue either.

    Wow, I didn't realize Sprint was that far behind. I've been doing VOLTE for over a year on Verizon, so I guess I just assumed the other big carriers also supported it. Anyway, glad to hear they are rolling it out. Sure is a great feature to have.

    This is, in part, due to the wireless infrastructure that is used between the major carriers... Verizon and Sprint, both use CDMA technology, whereas AT&T and Tmobile utilize GSM.

    Originally, only GSM carriers allowed the use of mobile voice and data, to be used simultaneously (became seamless at/around 2003-2006). where as verizon and sprint, lagged a little, verizon gaining their support when they fully launched VoLTE... sprint still in a somewhat soft launch only allows it in select areas that have a good LTE signal.

    I used to do signal testing for all carriers with a majority of sprint, and used to remember exactly how all the architecture works, but it's been over a decade...
