IMEI2 becomes the default IMEI with an eSIM.
Hello,
On our Ivanti Neurons MDM, we use this API to retrieve IMEIs:
getImei() in TelephonyManager is equivalent to:
getImei(getDefaultSim());
So when the only sim is inserted in the second slot:
getImei() is the same as getImei(1) causing duplication in the report.

The API used to retrieve IMEIs seems to target getImei(getDefaultSim()), which causes problems with eSIMs that use IMEI2.
It therefore retrieves IMEI2 as the default IMEI, which can cause problems with registration consoles such as ZTE, where only IMEI1 is entered.
Is there a way to correct this to avoid IMEI swapping?
Regards.

Maybe this is default behavior by Android (and in my opinion an issue) as we see the same when the device has an IMEI, it's not recognized as an eSIM by the MDM but as a normal SIM with the IMEI2.
For me it looks like an Android internal issue.
Need to correct my first paragraph:

I believe you are correct. From a device perspective, eSIM is considered second sim when you have physical sim tray as well.
Hello, do you have any updates on this?
We have been experiencing such problems with IMEI1/IMEI2 for several years with WorkspaceOne. Unfortunately, only the default SIM (and IMEI) is beeing reported there. A SIM is set as the default if it is the only card in the device or if it is the default card for calls.
With multi-SIM devices (regardless of SIM+SIM, SIM+eSIM, eSIM+eSIM), each radio interface has its own IMEI. Before eSIMs, this was already a problem when someone inserted the SIM into SIM2.With WorkspaceOne UEM 26.02, reporting for multiple SIM slots is finally coming. Unfortunately, I don't know what APIs they use in the background.
In theory, the UEM should report all IMEIs, regardless of whether the radio interfaces are used or not. If there is an enrollment restriction, the UEM should check whether the IMEI appears in any radio interface of the device.
