If you have the stick-on device, it will connect to the phone it recognises first - but only a phone it's already been paired with.
We look at how the vehicle is being driven, regardless of who is driving, so it doesn't matter which driver's phone is connected.
When we're working out your renewal price, we take your driving over the year into consideration. All drivers should drive safely to make sure your policy is unaffected.
If you have the plug-in device, it will send us data on how the car is being driven, regardless of who is driving.
