Hey guys

I have a Sony xperia Z1 honami. I bought this phone in December and i love it! But still to this day i cant seem to make the MMS work! I cant get pictures.

I am running on tmobile in USA

I got a z1s with t-mobile and I have not been happy with there MMS or group messaging since. To me its a service issue because it worked fine when I was on AT&T unless its a phone issue but I have no way to rule that out because I don't have any other phones to try...

that's odd, how about if you try handcent for group messaging
