Support for a device on each cellular provider isn’t automatic. There is are certification and approval steps that cost them money upfront.
Charging fees is unlikely to recuperate their network engineer costs so from a consumer perspective it’ll look like blocking but that’s not the reality. It’s that the device wouldn’t be in their supported device list.


This is one of the reasons that causes me to pause whenever I’ve considered purchasing one. My state also has a yearly fee.
I work from home and don’t drive to justify these fees so I just keep my long ago paid off vehicle well maintained for a fraction of the cost of a car payment.
