Sky mobile will not allow you to remove parental controls, and thus access your full SIM functionality (which you have paid for), unless you have a credit card, or have a credit agreement with them. I have neither and offered a passport / mortgage documents to prove i am an adult. This back and forth via approx a dozen emails and calls resulted in sky saying its their policy and nothing can be done. I asked for it to be raised as a formal complaint to their policy / management team. This took several more emails and calls and they eventually said the complaint would be raised and then immediately marked as resolved, as nothing could be done. This is a frustrating outcome and its a silly policy that allows no way to prove your adulthood apart from essentially getting into debt via a credit card, or getting a credit agreement. Customer service was polite, but kept going in circles in an effort to simply wear you down. Pretty poor show sky!
