When Sofia call his boyfriend Hakim from the abandoned hotel, the phone show no card sim but she dial and connect a regular phone number anyway.
In the opening 4x4 driving scene, Sofia has her thumbs wrapped around the Defender's steering wheel. Assuming her father was an experienced off-roader, he would have taught her to keep her thumbs on the outside of the wheel. If the vehicle snags it might wrench the wheel around and break her thumbs in the process.
