Try using Fido's Extreme Text Messaging service (not available for prepaid accounts). On your phone, while not on wifi, browse to http://www.fido.ca/m/etm. From there you can enter numbers to block from receiving texts, but i don't know how well it support international numbers.

block incoming international sms is a feature that may or may not exist depending on the manufacturer.
have you done a search on google to see if there is an application for your mobile os that can block incoming interational sms???
