My SIM card is stuck inside the slot of my laptop and I can't get it out without causing further damage to my laptop.

Every time I log in gnome-shell prompts me for the PIN. Whether I am about to use it or not.

On my phone I know I can disable the PIN altogether so that it doesn't get requested again (even if place the SIM card on another device). How can I do the same in Ubuntu?

I don't have a piece of hardware like this on my computer to test with. Do you know the name of the daemon that is prompting for your password? Try sudo pstree while it is present and looking for something that might look like it. From there we might be able to alter it's config, uninstall it, or disable the hardware –  Huckle May 28 '12 at 5:09

This is bug #704123 marked as `fix released'. As a bug report this is off topic here. –  Takkat May 28 '12 at 6:44
    
@Takkat, how is this a bug-report? I am asking for a workaround. I am on 11.10 –  d_inevitable May 28 '12 at 15:41
    
@Huckle I suppose that would be NetworkManager. –  d_inevitable May 28 '12 at 15:48

You can disable PIN checking using the built in GSM modem as described here.

That looks promising, but how do I determine the path of the modem? After all it is inbuilt and I cannot unplug it. –  d_inevitable Jan 20 '13 at 3:20
    
I was able to find the device with hwinfo. –  d_inevitable May 26 '13 at 1:25

Usually one would take the sim card put it in a phone and change the pin code to 0000. which effectively disabled the pin. I don't know of any way you can change the pin of a sim card through the 3g modem in your laptop somehow. But if you can that would be the way

You can store the PIN in the configuration, then network-manager won't ask for it again.

Graphical Way

Open Network-Connections, go to tab 'Mobile Broadband'

Screenshot, Network-Connections

Click 'Edit' and go again to the tab 'Mobile Broadband'

Screenshot, Mobile Broadband

Enter your PIN here, then it shouldn't ask for it again.

Command-line

This is an alternative to the way described above. No need to do both ways!

cd /etc/NetworkManager/system-connections/

There open the configuration-file of your broadband with your favorite editor. In my case: sudo gedit ./beeline There should be a [gsm]-section, here you can add your PIN code pin=1234. If the gsm-section does not exist add the following to the end of the file:

[gsm]
pin=1234

In 11.10 due to a bug it did ask for a pin if you had carried out the steps you have described. It was a known bug. Not sure how it is now, as I've disabled the PIN on the SIM card. –  d_inevitable Nov 3 '13 at 15:09
    
Sorry, I didn't read the comments under your questions carefully enough. Anyway: Thanks for the hint. –  Rough Dude Nov 3 '13 at 15:15
    
In Debian Stable I got this to work with NetworkManager version 0.9.4.0-10. I assume the bug is fixed now, and the fix is in Ubuntu a long time now. –  queueoverflow Sep 19 at 9:42
