How do i block a number on prepaid?

I've been getting retarded sms's from this random person, followed by a call from a private number where nobody is answering back at me.

Most smartphones have the ability to block all comms from a certain number. Google your phone model and bocking a number.

If I remember correctly, quite easy on an android or WP. Not sure about an iTerrible though.

Unfortunately we can't block calls or sms's on our side. Like agentrfr said, blocking unwanted numbers from your smartphone is the best option. *DM*
