How to unlock a phone Sagem

Model: All
1 - Switch on your phone with an unauthorized SIM card,

2 - The phone will display "SIM LOCKED"
3 - You can now enter the unlock code.

Warning
if your mobile displays "CODE POSTE" it means you have
a Security Code, can be 0000 or 1234
but we cannot calculate this code with your IMEI
because it's not the phone code
but the Telephone User's code!
