Currently I have a Mikrotik LHG LTE antenna/router. That device is supposed to be installed later on the rooftop. It has a major downside... you have to climb up there to change the SIM card...
I could design a PCB M.2 adapter with an eSim on it. BUT I have absolutely no idea how to provision the eSim with connection profiles from the service provider. Let's start with some questions:
Q1: Currently if you want to use an eSim of a smartphone, you only need to scan a QR code that you could buy from your LTE provider. What does the phone do with the QR code??? Is it an url? Does the smartphone send the eICCID of the eSim to a server somewhere, which then in return starts the provisioning of the eSim? (link/url valid only once apparently)
Q2: How does it work on smartwatches with integrated eSim but without camera to scan the QR code?
Q3: Could we simply provide the eCCID to the service provider so that he could trigger the provisioning manually?
Q4: Could we use any eSIM chip out there or does the LTE service provider only accepts predefined models?
Q5: Apparently for Snapdragon based modems you only need to activate the BIP (Bearer Independent Protocol) mode and PDP context:
(It is on by default I think)AT+QCFG=”bip/auth”,1
AT+QIACT=1
What should we do next???
Q6: Apparently you could provision the eSim with several connection profiles from different service providers. That's great. But how???
Yeah, that's a lot of tough questions
