I want to share some information about Android Enterprise zero-touch in combination with dual-SIM devices with you guys and want to know if somebody of you experienced the same behaviour.
So to get into the topic, as you guys know dual-sim devices have two IMEI numbers. When it gets to zero-touch registration, we as a reseller only register IMEI1 to the zero-touch portal. So we thought for the latest time, that the device is completly secured and will always enroll to our EMM. But we find out, that it depends on were you put the SIM in, if the registration will take place or not. So if you put the SIM in slot 2 (SIM-slot 1 is empty), the device will not get the zero-touch registration and you can go completly over this. Even if you enroll the device with wifi, it wouldn’t get the registration as long the SIM is in slot 2.
Does anybody of you guys know some details about this. We thought, that an uplaod of the primary IMEI will register the whole device, but obviously it’s not.
I’m very interested in your feedback.
