Security Code?SIM Card

[skandalous]

i have a nokia 8390 phone my original sim card i have in it says "Enter PUK" and i dont know it so i put in another sim card from another phone. Now it says enter "security code" and i cant seem to get past that point. I have tried the 12345 thing i read in other posts but it does not work so now what do i do?
