Im getting it all second hand, but I think he bought the phone sim free on amazon, then got a sim deal from 3 that gave him an allowance of calls, texts and data. However when he tried to go online it wouldnt work, and he got directed to a page which got him to agree to the £5 charge. Then when he looked at his account tye £5 had been taken off his £15 credit. What I cant work out is, if he bought a £15 plan, why did he have £15 credit balance, on my plan I pay a tenner a month for my plan, but my credit is zero ( android on giffgaff)
