How to Unlock Your Motorola L6 for Free

1. Purchase a SIM card from a GSM cellular service provider. SIM cards are normally sold at the service provider's retail stores and customer service centers. Most GSM cellular service providers offer both pre- and post-paid SIM cards.
2. Call your current cellular service provider and ask for the unlock code for your Motorola L6. Service providers in the United States generally will give you the unlock code free of charge, if you have an active account that is in good standing.
3. Remove the existing SIM card from your Motorola L6 and replace it with the new SIM card you purchased in step 1. The SIM card is located under the phone's battery. You can access the SIM card by removing the back cover and battery from your phone.
4. Replace the battery and back cover, and power on the Motorola L6.
5. Enter the unlock code using the key pad on your Motorola L6. Your phone is now unlocked and will work with the new SIM card.
