The instructions you will receive are to unlock the phone with a different carrier's SIM card. If you would like to go ahead and unlock the phone without a SIM CARD (For use with a different carrier in the future for example) follow the below instructions:
Note: If you have ATT but still want to unlock (and not use one of you 5 free unlocks per account - therefore you selected non-AT&T Mobility Customer in the unlock request) DO NOT use an ATT sim card in the phone until AFTER you receive the unlock code (usually 4 hours) or else they will send you a "denied - the device seem to be active on a customers account..."

These units do not keep time without a SIM card installed. You may not have to maintain service, but you do need to have a sim card installed. Incorrect time causes issues with SSL connectivity, which means it would only be useful to take pictures/video and listen to music.
