How to reset/refill the security question
Dear all,
I have my own iCloud account with my personal email address (yahoo.co.uk; iCloud.com; me.com) and using it for 3 devices. Everything's OK for iCloud Key chance, iCloud email, iCloud driver... But unfortunately I forget the security question, so I can't purchase anything from AppStore. Now I want to upgrade my iCloud account to 20GB of storage, but it can not be done without security question.
So, can I reset/refill the security question? My mailbox is almost full... Please help!
Many thanks and Best regards.
