Have you tried to send MMS with ting via wifi??? If so you will have found what I have, you can't!!! Nothing was said about this when I was looking into going with thing. This translates to outrageous data charges like before wifi!! I am hoping for a work around like gmail, and it would seem that gmail is the work around and can be sent via wifi if the recipient is not blocking incoming mail. All in all this really sucks and should be told loud and clear.. but it is not!!! Shame on you Ting
If it sounds too good to be true..guess what!
