OK, so I haven't been able to determine anyplace else. I'm not on Revolution #3, soon to be #4 if I can't convince Big Red to change me out. I'm hoping! IS the Bionic Voice over LTE? I'd love to jump over, but that's an important tidbit to me.
I'm pretty sure no phone is VOLTE. I know they've tested it, but I don't think they've released a VOLTE device yet. Hopefully next year! Gotta spread that 4G around a lot more first tho.
Actually, the Revolution Rebooter IS VOLTE. But, see the second part of it's name for the reason it's junk. *sigh* Ended up getting them to swap me to the Bionic because after 3 phones in ONE month I'm fed up. VOLTE or not I'm good after that. I'm hoping this phone is though since it's been SO long in the making.
