SMS competition & trivia scams

What is an SMS competition & trivia scam?


Common SMS scam message


An SMS competition or SMS trivia scam usually arrives as a text message and may encourage you to enter a competition for a great prize (like an mp3 player). The message (or sometimes, an advertisement) could also invite you to take part in a trivia competition, with a great prize on offer if you answer a certain number of questions correctly.

The scammers make money by charging extremely high rates for the messages you send, and any further messages they send to you.

With trivia scams, the first lot of questions will be very easy. This is meant to encourage you to keep playing. However, the last one or two questions that you need to answer to claim your ‘prize’ could be very difficult or impossible to answer correctly (and may even require you to guess a random number).

Warning signs

  • You receive a text message offering you the chance to win a great prize by sending a return text to enter a competition.
  • A text message tells you that you could win a great prize by participating in a trivia competition over SMS. The first message may even contain a very easy question to tempt you.
  • The text message (or other advertisement) does not give you details about how to stop receiving more messages.
  • The first text message, or the advertisement for the competition does not contain all the terms and conditions.

Protect yourself from SMS competition & trivia scams

  • Use your common sense: the offer may be a scam.
  • Read all the terms and conditions of any offer very carefully: claims of free or very cheap offers often have hidden costs.
  • Make sure you know how to stop any subscription service you want to sign up to.
  • It is best not to respond to text messages or missed calls that come from numbers you don’t recognise.
  • Be careful of phone numbers beginning with 190. These are charged at a premium rate and can be very expensive.
  • Look out for SMS and MMS numbers that start with 19. These are charged at a premium rate (sometimes even for receiving a message) and can be very expensive.


Do your homework

Contact your mobile phone company to ask about the number—they will know if it comes from a premium rate service. You could end up with a huge phone bill if you engage in a text message conversation with a number that charges you for messages sent as well as received.

If you did not want to participate and you receive more messages, make sure you tell your phone company that the charges are not being made with your permission.


It’s best not to reply to any text messages you receive if you don’t recognise the number—it only shows that you are interested and you could then receive many more similar messages.

If you are interested, make sure you understand how much it will cost you and how you can stop receiving messages. If you want to be extra safe, ask your telephone company to put a bar on premium rate services (190 numbers) from and to your phone.
