I received three in a row of these messages on Bell Prepaied Sanyo phone.Whasss up??

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

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.

I just got some of these texts too.. I replied "STOP", and it replied back (but the number was 4123) and it said "Sorry your message to (416) 555-2121 could not be delivered. We tried to deliver the message 3X with no answer. Please try again later."The fact that the reply doesn't sound professional (at all) gives it away to be some sort of scam or something.

Received 4 garbled text messages from this number

I'm in the 780 area code and I've just received the same two messages. Both received at 16:15 on my BlackBerry and both from (416) 555-2121.

1st:

2nd:

I thought it might be a script of some sort to triger information send back. I have a firewall on my BlackBerry and if this continues I'm going to enable it and see if it will block these texts. Also, if enough people call their providers, a 'harrasement investigation' is conducted between your provider and your local police. I've done it before.
