How to Unlock a Cingular Motorola Phone for Free

Instructions
1. Call Cingular and request the unlock code. You can reach Cingular by dialing '611' from your cell phone. Once customer service comes on the line, explain that you wish to use your phone with another service provider and that you need an unlock code for your Motorola handset. He or she will then file an unlock request with Motorola and e-mail the code to you within one to two days. The code is provided free of charge.
2. Place a non-Cingular SIM card into the phone and turn it on. You must use a SIM card from another carrier to prompt the phone to ask for the unlock code. If you are unlocking your phone before switching service providers (and thus do not have a new SIM card yet), ask a friend to briefly borrow his. Once the phone recognizes that a SIM card from another carrier is inside, a prompt will appear on the screen asking you to enter the SIM Subsidy Unlock Code.
3. Enter the unlock code. Take great care to enter the code exactly as provided. A message will appear onscreen confirming that the phone has successfully been unlocked.
