Make sure that you have the correct sms service center number; try +12063130004. You can get the "+" sign by holding down the zero key for about 2 seconds.

For some reason i can't send/receieve texts from my T-Mobile Shadow. I 'send' them, and they go straight to my outbox, and just hang out there. I can't find anything in connection settings that would stop this from happening...anyone know have this problem before. Also, what info should I provide so someone might be able to help me.

thanks!
