SIM card isn't detected / re-initialized when removed and re-inserted.

[damellis]

When you remove the SIM card and then re-insert it, it's not automatically detected by the GSM module, leading to lots of problems (can't make calls, access the phone book, etc). You need to reboot (e.g. reset the microcontroller which will reset the GSM module) to re-detect the SIM card and use the phone again.

It seems that for the GSM module to automatically detect the SIM card, we need to use an eight-pin SIM socket rather than the 6-pin one on the current phones.

Another option would be to have a menu item that tells the microcontroller to restart the GSM module, which should allow it to re-detect the SIM.

Is rebooting the GSM module expensive in time or power? Maybe upon a failed
call or what, it can offer to reboot the GMS module.
