If you left your phone on during your flight or cruise then you should fully power down and restart your phone. Once your phone powers back on it should automatically select an available roaming network.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.When does a Personal Extra Number (PEN) subscription start?
