By unlocking your Nokia 6125 mobile phone, you can connect it to any network you want instead of being locked to one network. You need an unlock code for this, which you can try to obtain by contacting your phone's provider. If that does not work, you can buy one from a third-party website. You need to know your phone's International Mobile Equipment Identity (IMEI) number for both cases.
Instructions
1. Find your 6125's IMEI number. Do this by typing "*#06#" on the keypad, which causes the IMEI number to appear on the screen.
2. Call your phone's provider, give your phone's IMEI number and ask for an unlock code. If the representative refuses to give you a code, go to a website that sells unlock codes (see Resources), give your IMEI number and purchase a code.
3. Remove the battery pack from the back of the phone, then remove the phone's subscriber identity module (SIM) card. The phone must be off while you do this.
4. Turn the phone on and enter "#pw+CODE+1#" on the keypad, where "CODE" is the unlock code provided to you by the customer service representative. Press the "*" button three times quickly to make "p" appear on the display and press "*" four times quickly to make "w" appear on the display. Press "*" two times quickly to make "+" appear.
5. Look for the message "SIM Restriction Off" to appear on the display. The phone is unlocked.
