Is it a good enough solution for IMEI tracking to use an alternative device to provide a hotspot connection?
This approach appears to protect any new device that hasn’t inserted a SIM card from being identified.
But I’m not sure how much information is carried to the second device by using hotspot.
Is this a good solution so far? Should I try to spoof IMEI?
They certainly can be spoofed or cloned.
But thats as illegal as it gets and faces serious proscecution.
Spoofing IMEI isn’t helping if OP pays for the service with bank account / credit card, or walks in a store to pay but with face exposed, or turns on the cell-hotspot device on at home (because they’ll be able to associate the SIM/Service-Plan with your address via cellular triangulation, and thus your identity)
