Modem Manager Crashes (Sierra 308)

Asked by Rei on 2014-07-06

Does modem manager in Ubuntu 14.04 support Sierra 308 device? Modem manager always crashes when I tried to connect to Internet or choose to enable Mobile Broadband. I thought it might be a bug so that I opened a bug report that is related to this issue (Bug #1337414). However, I was just thinking that the new modem manager might not support this modem.

There seems to be a problem with unblocking the SIM with the PIN.
What you should try:

1. Unblock the SIM manually:
sudo mmcli -i 0 --pin=<PIN>

2. Remove the PIN from the SIM by putting it into a mobile and follow the mobiles instruction on deactivating the SIM.
This has the obvious implication that the SIM is not protected by a PIN anymore.

What is the output of:

lsb_release -a; uname -a; lsusb

Thanks

When I checked the SIM in mobile phone, I found PIN security had already been turned off. I never use PIN when using this SIM card.

Here is the output of “lsb_release -a; uname -a; lsusb:”

No LSB modules are available.

I guess the modem was listed as Device 008. Is it possible to make this device work with modem manager? Will the result be different if I try using modem manager of other Linux distros (beside Ubuntu)?

yes, 0f3d:68a3 is the ID of the device. You can now use it to find guides.

Where should I find guides that are related to this issue? I have been searching solution for this problem (including googling the Modem ID) for almost one week without luck. Could you please tell me what I need to do to fix this issue?
