Every carrier is moving away from SVDO and SVLTE. So if you want that where are you going to go? If you realize that only VoLTE has a future then the same question exists. Where are you going to go? No carrier has that built out yet.
You're not really listening, you're trying to win an argument.
Sprint has been and continues to provide SVDO capability, you simply need a phone that supports it.
But you can't buy one any more.
Sprint does not have LTE coverage everywhere that they have 3G.
Your whole either / or deal is really missing the point of an essential reality.
You seem to think that SVDO is an alternative build out.
It's not.
It's a missing phone feature - about this >< much additional microcode in a programmable modem - that would be nice to have until they get it together on VoLTE.
My last Sprint phone supported SVDO and VoLTE *in hardware*.
Had I kept it, I could have easily transitioned to VoLTE when it arrives.
But I didn't and I can't.
And they didn't warn us.
It's really, really, really simple.
