Somebody please help me.
I've just got my curve 8320 unlocked from t-mo. When i put my ATT sim card (the one with 3g logo), i got new message automatically in my BB inbox.
"453 error invalid number. please resend using a valid 10 digit mobile number or valid short code."
What should I do to fix this. I'm sorry if i repost this problem, because i've tried to search and i can't find one. Thanks for the help.
