If you have the stick-on Ticker box, yes. This is a condition of your insurance:
You need to keep mobile data and location services on when you drive
Your phone must paired with the stick-on Ticker box and in the vehicle when you drive (switched on!)
Your Bluetooth must be switched on when you drive
These conditions apply to all drivers on the policy.
If you have the plug-in Ticker device, you don't need to worry - the device has its own network that it uses to send us data.
