I have had Republic for about a year now and love it. The Defy XT leaves a lot to be desired, but it is perfect for my wife, who makes most of her calls from home over wifi. I plan to switch to the MotoX when my work phone gets turned off in a few months. For now, my Defy is sort of a back up phone. Anyhow, I have had no problem with RW. Customer service was super responsive the one time I needed them and managing my account online is way more straight forward than any other provider I have ever had. I even got my tech illiterate parents to switch. When they heard "wifi calling" I just about lost them, but it is so simple to set up, they decided to make the switch. I probably sound like a fanboy here, but it really is the best wireless provider I have used. I used to be genuinely pissed off every time I looked at my account online when I had Verizon, then AT&T and finally Sprint. Not the case with RW. There are no bizarre fees I have to decode with RW. Same bill every month. That simple.
