2016 Friends & Family Free Tablet Line + SyncUp Drive Compatibility?

I have 2 free tablet lines from the 2016 friends & family promotion which have mostly been going unused. I'm interested in trying out SyncUp Drive. From what I've read the newer models are esims only. I had a few questions if anyone can answer them.

  1. Anyone successfully using the free tablet sim (or paid tablet sim) in a SyncUp Drive?
  2. If I have to buy a esim only SyncUp Drive, can I apply the free tablet line to it as a esim?
  3. Any issues or reviews on SyncUp Drive?
  4. Do I need a specific model?

I'm mainly interested in GPS tracking only. Does it work even with the vehicle off or does the device shut down with the car?
