T-Mobile
As a T-Mobile user that has used Wi-Fi for calling and texting, it was great to hear T-Mobile assurance that all their future phones will have this future. I actually find it odd that it's not on every phone on every network in theory. But then you realize that the top cellular providers are making so more profit on data changes. How else will they make up for the lost profits from the easy money made from texting chargea?
As a T-Mobile user, the WiFi connection is really convenient but since the service isn't as widespread as it's competitors, it is increasingly more significant. I hope the ability to receive and send MMS will be worked out since it is not currently possible.
It's absolutely genius of T-Mobile to hand out routers to lend ($25 deposit) so their customers to use with some T-Mobile software in them. I'm seriously considering since it is a great router that handles the 802.11ac standard.
