you do not need an IMSI for ConnMan. You just need a proper unique
identifier that is consistent. Using the hardware serial number in case
of CDMA should be a good enough interim solution.

We are using the IMSI for GSM since we wanna bind stored settings
towards the SIM card. So that hardware swapping has no effect on the
user experience. With CDMA we could neglect this actually. So far all
CDMA account are still bound to the hardware itself.
