You can fully flash a phone for use on other network providers.
Cell phone owners who desire to use their device with another network provider must flash their phone before it works with their new phone company. A number of cell phones come with pre-installed programs that stop anyone who wants to switch carriers, unless they unlock their cellular device first. However, once you learn fully flash your phone, you can use it on another network without any problems.
Instructions
1. Charge your phone completely. Then, take out the battery.
2. Gently ease your SIM card from its location. This tiny white card lies in a silver compartment close to your phone battery.
3. Find your IMEI number and jot it down. You can find these 15 digits on the rear portion of your cell phone close to your scan bar on a sticker that contains silver. Replace your SIM card and battery.
4. Contact your cell phone company. Ask the employee with whom you speak to provide you with a code to unlock your cell phone. Note, that the worker needs your IMEI code to provide you with the unlock code.
5. Power on your cellular device. Type "+1#"and hit "Send." Enter your unlock code. Wait for the phone to read "SIM Restriction Off" to use your phone.
