Whatever you may want the restrictions off for it is quick and free all you need to do is log into your giffgaff account and in the menu there is a section in My giffgaff that will say "Phone settings" and just turn the restriction off, it is that simple. Other networks charge for the removal of the restriction but with giffgaff it is free and simple and will take upto 24hrs to clear.
A Machine Readable Passport from some 120 countries and Full Driving License Full /Provisional are the only documents you can use to lift the adult bar. Even an agent cannot lift it for. The bar is in place to stop minors accessing gambling and adult sites. When I was Vodafone they made no charge to lift their version of the adult bar.
@lukevann123 HI, To remove the Adult Bar you will need to enter the number ofa Valid UK Driving Licence Full or Provisional or a Machine Readable Passport from some 120 Countries. An Agent is not authorised to carry out this operation as proof of age I needed. AL networksI need Age Verification on the recommendation of OFCOM.
