I have a nokia n9. Often restarts. What could be due to the frequentrestarts? The phone is new. Since the operator Orange Poland.

First suspect with restarts is the sim card. Try another sim or get a replacement sim and see if it helps.

Check a different sim card. I wonder if there is a bug in the software. As you know pretty much Orange interfere with standard soft. Could this be the cause?

[cjlim]

Network intervention is usually bad news. That's why I avoid them like a plague. My vanilla version is very stable and no problems so far. Touch wood. 

However, restarts are commonly associated with faulty sims so worth a try.

On a different SIM card is the same. Is the Nokia Care can downloada clean soft? Or is it a defective copy? The phone is under warranty,so I have to use it. Thanks for your interest.

You should perhaps consider resetting your phone first. Backup your data, then goto Settings>Reset>Clear device. This will wipe the phone and return it to the out of the box state so remember to backup essential data first.
