i get these messages as well, and i think they signify when somebody sends you a picture message, but you don't have a plan that allows you to receive them as a picture.

it's wierd text because someone tried to sent u ã picture or mms. the phone number is ã general number from ã rogers network .

I just received 2 unintelligable SMS messages from this number which I will charged for since I don't have a plan.

I get the same messages. I have no idea why. Are you with Virgin Mobile? Because it might be one of their messages, but it has no meaning so I don't understand why they would send it.

i got it too how can i stop it

What does this mean on my itemised calls?  the number called is 2121, SMSReceiveReply0Branded, 1 event (cost=0).
