Zero Touch Enrollment Network Specifications

Hello!

I'm looking for information regarding the network specifications for the Zero Touch Enrollment as well as any phone-home network requests. Are there any logs we can pull from ZTE or the Android device during enrollment?

The reason I'm asking:

We have thousands of devices that have been enrolled in SOTI MobiControl over the last few years, and about 1000 of these were enrolled via ZTE. We've had no issues with this until early March. I can't find a rhyme or reason for this, but certain devices that were successfully enrolled, configured by an MDM, QC'd, boxed up, shipped to the end user, and then powered on will get the message below before the eSIM is activated.

These are Honeywell CT47 devices with dual SIM cards (1 physical Nano SIM and 1 eSIM). The device above was added to ZTE using the IMEI number over a month ago and was successfully enrolled, but when powered on later and connected to Wi-Fi, it reset itself before the eSIM could be activated.

This issue is only happening to devices that are factory reset while on-site and connected to the Wi-Fi only. My best guess is that the Wi-Fi network is blocking something during the enrollment process, as this reset issue is not happening on devices that have been enrolled and working for months.

Thanks for your time!
