Download Article Show Download Article This wikiHow teaches you how to figure out if a phone is unlocked when you don't have a SIM card. If you bought a new phone second-hand or from a third-party dealer, you want to make sure it's unlocked so you can use it with your carrier. Otherwise, it can only be used with the carrier it is locked to. The easiest way to check if your phone is unlocked is to use another SIM card. If you do not have a SIM card, you can check if your phone is unlocked using the Settings, but this may not be 100% accurate. You can also contact your carrier, but they may not be able to give you the information you need.
