If I top up by premium rate SMS, will I be charged again in the future?

No, CardBoardFish does not run ANY premium rate subscription services. When you send a 'CREDIT' text message to our shortcode, you will be billed exactly once and no more. Also, your mobile number and other personal data will never be shared with any 3rd party, and will never be used for any marketing purposes. Premium rate SMS topup is only available for UK customers at this time.
