Blocking SMS?

I think ,it is possible only if you are using symbian mobiles..Airtel not having that facility..But if you are using sis compatible mobile then using a software you can block..BUt if you are using java phones then surely you can't block... Happy mylotting..

It depends on your mobile phone, not the service provider. Samsung have that option, nokia doesn't. I think motorolla doesn't too. On other brands, I don't know because I don't have one. I'm just curious. Why don't you just delete it when you receive a message from that number? =) If you block him/her I think he/she wouldn't even know you blocked her.

It is not possible to block the message from someone, however there is an application that will block such messages and any contact from the number. I think it's called black list. I hope your mobile is compatible to the application. Check your cell.
