Every Android device i have can send text and MMS, and video messages via wifi. Even non Android phones can do that such as BlackBerry and Windows. However, it seems with the 4.3 update that has now changed. I can only send texts and sometimes that comes back as UNSENT and i have 2 click resend. Very horrible. I hate Android and their lazy OS updates. I also have a GSM phone and T-Mobile gives all their phones FREE wifi calling, so not sure if u can't do what everyone else does because u have a CDMA phone with Verizon and they're just good at ripping people off.
I think this is another ploy 2 make people use data who don't have unlimited data. Since I'm guessing MMS would fall under data by how many KIDS the video file or pic one is sending. Ughhh!
