My car insurance is now requiring a smartphone to use their tracking device. Can you have a smart phone run on a prepaid card like Tracfone?

I've never had one before so don't understand too much about it. Would that mean the phone would have to be on all the time you are driving? That would take the minutes down fast.

Tracfone is now selling some smartphones at a reasonable price.
Insurance app requires a phone compatible with Android 7 or higher and iOS 12 or higher.

Any suggestions on this would help me understand it better. Thanks.
