Yes, the HTC One supports SVLTE.

Thanks again!  I guess I'll just need to make sure to keep the One and not get a tri-band, at least for now

Sprint's Triband LTE devices do not support simultaneous voice and data. It is physically impossible with current technology to do so with a single transmission path. Sprint is counting on that people would prefer to have a competitively priced smartphone with better battery life and LTE performance than simulatenous voice and data.

 

Otherwise, Sprint would need to work with OEM's to create a dual path device that supports TDD-LTE. It is possible. But the resulting device would be more expensive than their carrier counterparts and miss the battery savings and better LTE performance with weaker signals.

 

Sprint is betting the farm that SVLTE is not a big deal for its customers. We will see how this pans out. And as people use voice less and less, it may become a non issue. I personally rarely use voice anymore except to talk to old people, like my parents. I don't even talk to my boss on the phone hardly ever.

 

Simultaneous voice and data will likely return to Sprint smartphones with VoLTE. Which is probably at least 18 months out.

Thank you for the information.  Not really the answer I was hoping for.

I currently have the HTC One.  Am I correct in assuming that once LTE is live in my area, I should be able to do SVLTE with it?

So, help me understand...  

Will the tri-band, single radio phones ever be able to do simultaneous voice and data? If so, are we talking several years out?  Using the phone as a hotspot is an important capability for me and I need it to not kill the data connection if a call or text comes in.
