    • I have an iPhone and am receiving charges for SMS sent to a UK mobile number 447786205094. Why?

      This is a known issue with Apple's Facetime and iMessage applications on Apple iPhone  devices. We recommend disabling Facetime and iMessage so it will not be able to automatically send SMS to this 447786205094 number. Any SMS sent to this number automatically by your phone can not be refunded by OneSimCard. Additional questions regarding iPhone applications and how they communicate should be directed to Apple Support.
