Does it cost anything to become a member?
There is no fee to join Extra; however, you will be charged your usual network rate when sending a text message. If you send the text message whilst onboard our ships at sea, please note that the cost will be approximately 50p. This is because the text will be sent via our onboard network, MCP. You will not be charged for the text you receive with your membership number included. You will only be charged for the text you send.
