Text/Video Messaging 
- Don't reply to text messaging (also known as SMS or EMS) or video messaging (also know as MMS) that is abusive or obscene. Your mobile service provider. e.g. Organge, T-mobile, Vodaphone etc. should have a number that you can ring to report abusive messaging. Try their web sites for detalis.
- Be careful who you give phone numbers to and don't leave your mobile lying around when you are not there
