The SIM switcher is controlled by a GPIO pin, and it does not give the modem a indication that the sim has been switched.
The modem is a Sierra MC7710 set to use ATmodem commands,its configured to disable the SIM card connection when entering low-power mode.
An example of how i switch the sim:mm_modem_set_power_state_sync(modem, MM_MODEM_POWER_STATE_LOW, NULL, &error);
sleep(3);
int fd = open("/sys/class/gpio/gpio9/value", O_WRONLY);
write(fd, card, 1);
close(fd);
sleep(3);
mm_modem_set_power_state_sync(modem, MM_MODEM_POWER_STATE_ON, NULL, &error);
(example is simplified)
So what i am missing is a some functionality to tell ModemManager that
the SIM has been switched,
and thereby reinitializing the the MMBaseSim object. Kind Regards, Troels Olesen Den 06-01-2016 kl. 16:53 skrev Dan Williams:

I can switch the SIM card when the modem is in low-power state. But when i return the modem to high-power state after the switch, the SIM data stored by ModemManager is not changed. Is there some way i can force an reinitialization of the SIM card data?Does the modem give any unsolicited indication of the SIM switch? Can you run MM with --debug and see what QMI notifications, if any, are emitted while in the low-power state when you switch the SIM? If we can get an indication of the switch, then we could trigger a re-init of the SIM information. It's also possible that we haven't enabled the right QMI notifications, so you might get nothing, but that doesn't meant the modem couldn't send something if we toggled the right message. DanI have looked at the ModemManager code, and found, that a modified version of the function "mm_iface_modem_initialize" in "mm-iface-modem.c", might be able to reset the SIM object data, and force a reinitialization. But figuring out how to do this has eluded me. Maybe from the function "modem_after_power_up_ready". I would appreciate your input, about what you would consider best practice. And if there already exists a way to force a reinitialization of the stored SIM data. And more important without rebooting the modem hardware. Thanks in advance for any help you can give me.
