<div dir="ltr">Hello Aleksander, I was lucky, after a reboot it just worked. Yes the EM7455 is integrated in the laptop. Thanks for making this stuff work! I executed the commands you said, with the effect that the connection stopped working and I had to restart the ModemManager. I'll just insert the output here: ------------------------------------------- # qmicli -d /dev/cdc-wdm0 --device-open-mbim --dms-uim-get-pin-status error: operation failed: MBIM error: Transaction timed out error: couldn't release client: MBIM error: Transaction timed out** Qmi:ERROR:qmi-device.c:3239:finalize: assertion failed: (g_hash_table_size (self->priv->transactions) == 0) Canceled # systemctl stop ModemManager Feb 04 07:07:51 host ModemManager[757]: [/dev/cdc-wdm0] unexpected port hangup!

I wonder why you get the SIM not detected, which is what the modem is reporting: ModemManager[2508]: <debug> [1485208245.529656] [mm-iface-modem.c:266] load_unlock_required_ready(): Couldn't check if unlock required: 'SIM not inserted' ModemManager[2508]: <warn> [1485208245.529956] [mm-broadband-modem.c:9541] iface_modem_initialize_ready(): Modem couldn't be initialized: Couldn't check unlock status: SIM not inserted ModemManager[2508]: <info> [1485208245.530024] [mm-iface-modem.c:1431] __iface_modem_update_state_internal(): Modem: state changed (unknown -> failed) What's the output of: $ sudo qmicli -d /dev/cdc-wdm0 --device-open-mbim --dms-uim-get-pin-status $ sudo qmicli -d /dev/cdc-wdm0 --device-open-mbim --uim-get-card-status -- Aleksander <a href="https://aleksander.es" rel="noreferrer" target="_blank">https://aleksander.es</a> </blockquote></div> </div>
