is there a way to block him!

i dont want to change my sim card...

please help me!!!!!Is there an existing software that blocks a certain number from sending sms on cellphones?
Unfortunately, there is not. You can try talking to your service provider, but if you have a Nokia 5300 my guess is that you have T-Mobile who are useless on issues like this (they'll just tell you to change your number if they can't block him). Call their customer care (611 on your phone).



Best of luck!
