At first, VoLTE will be used to deliver "Rich Communications Services" (which look like something similar to what Voice over IP/Video over IP outfits offer today) rather than completely replacing narrowband voice. It will be awhile before Verizon is willing to commit to that, due in part to LTE outages in late 2011.
On the flip side is MetroPC, which has pushed VoLTE as hard as it could.
Then there's Sprint, which will stick to voice over 1x for the foreseeable future, but routes Direct Connect over IP. Sprint's latest DC incarnation seems quite similar to one facet of RCS over LTE.
I recently got one of those Sprint pebbles that was sent even though i did not request. i finally set it up after nearly 1 hr of fighting with it. I was wondering:
1. How is this different that Sprint wifi calling ?
2. Can other sprint users outside of my house piggyback off this pebble ?
3. If I stop using the pebble after a few months, do I need to pay the $70 or is the $70 only apply if you never initially set it up ?
