They use a directory to convert between the stable identifier used, and 
the temporary one that can be changed, so that the stable identifier is 
fairly easily handled by humans. If only we would have that...

Oh, wait... we do. DNS.

You don't dial your IMSI identifier number nor your IMEI. You dial your 
phone number which when your IMSI or IMEI changes, the phone number is 
changed to reflect the new reality. Also you can't have session continuity 
as you change IMSI or IMEI.
