try it for a day or two WITHOUT sim card and WITHOUT sd card
yes, it is very annoying, but i suggest you try it.

Perhaps it can be related to your SIM and/or SD-card. If you are using an SD-card, could you try to use it without the SD-card for some days to see if same thing occurs? Regarding the SIM-card, you can try another SIM-card or order a new SIM from your network provider.

if the sim has problems, shouldn't the system notify of the failure and also fail gracefully, instead of randomly rebooting?

if the phone fails to communicate with the sim card, it generally loses signal and says something along the lines of "emergency calls only"
the phone rebooting or hanging means something is very wrong.
i suspect something has to do with a watchdog timer, but still, it shouldn't be rebooting the phone without any kind of warning or
if it is rooted you can do a dmesg, or leave a script running (locally or via adb) to collect dmesg and/or other log data and maybe see if something pops up in there.

If the SIM-card is removed or loses its connection, the phone should display the message "SIM card removed, restarting" and then the phone will restart. So a faulty SIM-card, can cause this behaviour.

That behavior is kinda unwanted.
I can't imagine my pc **bleep** its pants and rebooting without any warning or option to delay it, just because i removed a wifi dongle, or just because the ethernet cable came loose...
