asking for PIN number every time

[#1]

So I changed a sim card, and now every time I restart the phone, I am asked for PIN number. How should I make my phone remember that pin number? (I have X10 mini pro)

It sounds like the default SIM PIN number has been changed, so you could change it back to its default and see if it stops asking you for the PIN at restart.

Thanks, do you know where in settings can I do that? (I couldn't find it)

Thanks, there in the menu I found that "Lock SIM card" was on, I turned it off, and now it works.
