Turn off the iPhone. Locate the SIM card cover; it's on the edge of the phone between the "Sleep" button and the headphone jack.
Many cellular phones are sold "locked" in the United States. A locked cellphone will only work for the cellular account (that is, telephone number) of the user who originally bought the phone. In particular, AT&T Wireless locks iPhones sold with a two-year contract because the discounted price is subsidized. Although some people believe that unlocking a cellphone is illegal, the U.S. Library of Congress has found that unlocking your own iPhone for personal use does not violate any law. It takes only a minute or two for you to verify that your iPhone has been unlocked.
Things You'll Need
- Another SIM card for an active AT&T or T-Mobile account
- Paper clip
Straighten a paper clip and insert it into the hole on the edge of the iPhone, next to the SIM card cover. The tray containing the SIM card will pop out. Pull the SIM card out of the tray.
Insert the new SIM card into the tray. Push the SIM tray back into the iPhone.
Turn on the iPhone. Wait for two minutes, allowing the phone to recognize the new card and associate it with the corresponding cellular network. Try to place or receive a call. If you are able to do so, the iPhone is unlocked.
