In gsm 04.08 9.1.22.3 it says "The Mobile Identity 1 and 2 IEs shall
not
refer to IMEI.". So a standard compliant network should never do that.
Have you actually seen that on any live network?
So in short, unless youre lucky enough to have the network page you
with your IMSI, it is unlikely you will see it.
Sometimes when some network components like the auth server/vlr are
overloaded with entrys or requests, then there are many imsis on the
air. And often at not-so-busy times, too. I've observed that regulary
but have not heard any fully explainatory conclusion to that yet.
