It's an excellent idea !
Looking for read_imsi implementation, I found qmimodem-legacy which fit
prefectly to my modem.
After a few fix because first Sierra net interface is buggy (wwan0), I'm
now enable to use fully "Connman - ofono"  features

I will try to cleanup my work, find a way to force use of
qmimodem-legacy for this Sierra chip and submit all these modifications.

Thanks again Denis
