My nokia 5800 wont send text messages they go straight to outbox saying it will resend in a few minutes?

Everytime i send a message it goes straight into the outbox and never sends it always keeps adding a minute on every time i try it, the centre message number is correct, ive tried formatting memory card, updating firmware nothing has worked please help|||Formatting memory card won't do anything. Are you on tmobile or other company? If on tmobile the centre number should be this +2063130004. Make sure you have full signal and most important, a message plan.


I've only had this problem once, and it was because the centre number was blank for whatever reason. Doing a hard reset and then updating the phone might work better than just updating the phone. hard reset is *#7370# i believe. It will delete all your data so back up your phone if you want to save your stuff.
