Remove the battery cover and the battery. The SIM card should be located near the bottom of the phone under the metal hinge. Insert or secure the SIM card with the contacts facing down, reinsert the battery and batter cover, and turn your phone on again.

If the message reads "PHONE LOCK," the SGH U600's automatic locking function is enabled. Enter the phone's password to unlock the phone.

When using the phone for the first time, you will be prompted to enter a PIN. The PIN is given with the SIM card for your phone. Enter the PIN number exactly as given. You may also have the "PIN Check" feature enabled on your phone, which will require you to enter the PIN every time the phone is powered on. You can turn off "PIN Check" in the "Settings" menu.

A message asking you to enter a PUK means you attempted to enter the PIN number three times and failed. You must contact your service provider to get a PUK.
