Every cell phone that Sagem offers contains a specific code that unlocks the cellular device. This allows you to switch to another network provider. Since cell phone carriers place software on the phones they issue, you do not have the ability to change carriers unless you unlock your phone. However, if you understand where to find the data you need, you can unlock your Sagem phone for free.
Type *#06# to bring up the IMEI number of your phone. Jot this number down on a piece of paper, and keep it handy.
Call your cell phone carrier. Ask the employee with whom you speak for the unlock code for your Sagem mobile phone after you tell him/her the IMEI code you wrote down earlier.
Power off your cell phone and take out its battery. Gently ease your SIM card out and put back the SIM card of another network provider in its place. Put your battery back in and then turn on your cell phone.
Type in your unlock code when your cell phone displays a SIM card error. This enables you to unlock your cell phone automatically.
