A lot of people are asking about being charged for payforit texts when they didn't subscribe to them in the first place. And how to stop further charges and get your money back. One way would be to require that the initial text is not charged for but is replaced with a text asking you to authorise the subscription. If you want to receive them, then you just follow the instructions in the text to authorise it. It could be follow a link or reply by text. After authorisation, you receive the original text and are charged. If you don't authorise it, you just ignore and no charges are applied.
