2nd data only sim linked to main sim

I am about to purchase a car which has the ability to add a data SIM card to access some additional functionality and apps.

I have a mobile SIM currently which I only use a fraction of the data each month.

Is it possible to get a 2nd SIM that is linked to my first SIM, that I can fit to the car and share the data usage?

No, this isn’t possible. You would need to purchase a second plan but be warned that there is no guarantee the SIM will work in your car.
