May be a stupid question, but I will ask anyway...
I assume that the phone will ask for a code if it is locked and you put in another carrier's SIM card but is there any way to figure out if your SIM is unlocked if you don't have a SIM card to try with? I plan to travel abroad and buy a local SIM card and don't know if my SIM is unlocked or not. I don't have another SIM with me to try out. I don't want to spend money buying a SIM unlocking code just to find out it is already unlocked! The person who I bought the phone from was not aware if the SIM was unlocked or not.
