Hey! I want to tweet too, you know? :P

What's wrong with my phone?!?!? OK so the problem is that i love to tweet and i never get to the chance to tweet on twitter through a text message! :(
Does anyone know why? I have a Samsung Behold and every time i want to verify it by texting 'Go' to the number 40404, in less than 5 seconds i get a text message saying from that same number " Free Msg: Reciever 40404 unable to receive message- Message Blocking is active"
Why does it say that? I have unlimited textings so I don't understand why it doesn't work :(

I get so jealous of my friends tweeting via text message and i always have to go online and tweet. It's kind of a hassle especially when something good happens while I'm not near a computer. Ugh. This sucks! Please...does anyone know why?

Help needed :D Por Favor.

Thanks, mibbians :)
