Hi…
Take a look at Peplink MAX BR1 Mini HW3 eSIM Setup - #3 by Captain_Nik
This url it is a sample what you need to do, using IC2. (Incontrol).
Will help you to understand how to use eSim.
You can use eSim from other mobile operators… Just check with the company (sim card owner) about some regulamentations when using network devices.
