<warn> [1415360816.142083] [mm-base-sim.c:1428]
load_sim_identifier_ready(): couldn't load SIM identifier: 'QMI
operation failed: Cannot send message: QMI service 'dms' version '1.3'
required, got version '1.1''

Basically, the "UIM Get ICCID" message in libqmi is configured to be
available if DMS service >= 1.3, and you're using 1.1. But, it is
clearly wrong as you can run that message with qmicli... I just
updated that in libqmi so that it requests at least DMS 1.1:

http://cgit.freedesktop.org/libqmi/commit/?id=ce723135cabb20e79f23f93a885410762c73d3ef

Also pushed to the qmi-1-10 branch, the current stable.
