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.The battery in my phone does not last long? It got fully drained during the flight to Europe. Why?
There can be a number of reasons why a battery does not hold a charge. Excluding the possibility of it being a faulty battery, there is another important factor to consider. If your phone is not registered on a roaming network, the battery will drain very quickly as the phone is constantly searching for a network to register on. So, if you get on a 6 hour flight and do not turn the phone off, or put it into airplane mode, by the time you land at the airport your battery will be drained and you will not be able to call back home.
The same thing will happen in those areas with spotty or weak signal network coverage - the battery will drain very fast. It is always a good idea to have an extra battery with you when you travel abroad.
