Bulk Registration of Electron with sim ect

I need a bit of help on how is the best way to register an Electron ID, Sim ID and our product ID on mass. We are trying to deploy 100 units at a time and need a bit of advice.

What is your setup like? What OS are you using?

Are you using Product SIMs or non-Product SIMs?

A bash script could be made to automate the registration process.
