Handling two IMEI for a single device

[testingniras]

So we have a requirement to manage hardware mobile devices in Service Now. For a single mobile, we will have multiple IMEI and each of these IMEI will have separate cellular carrier and their plan. 

We would like to have some suggestions to handle multiple IMEI for a single hardware record ?

I feel the easiest way to do this would be to create a new table and be able to link the IMEI to an Asset record. You can then either create a M2M table to reference in the related lists and/or create a list to then reference the custom table. 

Things to keep in mind, you will more than likely want to create functionality so that one IMEI cannot be tied to another device, much like a serial number. So disallowing insert/update of an asset where the IMEI is already referenced by another asset. This can easily be done if you load the table with all of your IMEIs and just hit on if the asset field is empty to allow and disallow if not empty. reference qualifiers will help with this too.
