Scams that come to you on your mobile can be difficult to recognise. They might come from somebody who talks as if they know you; they might come through a 'missed call' from an unknown number that you redial; or they might be upfront about what they are promoting, but have hidden charges.
You might be offered free or cheap ring tones, or the chance to win fantastic prizes.
When you reply to these messages or calls, you may find yourself disappointed in the product or signed up to a service you don't want or cannot stop. You could be left facing a huge phone bill.
If you receive a missed call or text message from an unknown number, the best thing to do is to delete the message or ignore the call.
Always do your homework before you agree to any offer you receive over your mobile and never agree to any offer that you are not completely sure about.
