Roaming: iPhone send SMS when turned on
I was charged for roaming SMS when I turned off and then on again while I was overseas. Checking with my operator, they said it is iPhone which is doing that. Android does not have this behaviour. Does anyone else have the same issue? Does anyone know of any tip to disable this behaviour? Can I disable the SMS function altogether on the phone?
Thanks/Samson
