Charges for shortcode services are listed in the promotional material or adverts for the service. The standard charge is 15p per message.
For contract customers, charges will appear under the Premium Shortcodes – sent & received - or Texts to other networks section of your bill. And charges for voice shortcodes will appear in the Calls to premium rate and other services section.
For Pay As You Go, charges will be deducted from your balance, so you need to make sure you have enough available credit to cover the cost of texting or calling the shortcode.
Most shortcode services will send you 1 or more messages as part of the service and you may be charged for 1 or all of them.
If a message starts with or was sent from FreeMsg or similar, you won't be charged and it won't appear on your bill.
Some services you've used may appear in the Three Pay section of your bill. Find out more about Three Pay.
