These are normally four or five digit numbers. Often they begin with 5, 6, or 8 followed by a key word. For example: 81111 VOTE. Before you sign up to an SMS/TEXT service, check that your handset is able to receive the service (for example not all handsets can receive or view videos).
Check whether you're signing up to a single (one off) text service with one single payment or to a subscription service where you will be billed on a regular basis (some ring tones operate this way, for example).
Companies offering subscription services must make it clear to you that you're signing up for a subscription service, and let you know:
• how much each text you receive will cost,
• how many texts you'll receive and
• how you can stop the subscription
