I was surprised to see how easy it is to unlock my cell phone with a mobile phone code. My phone is an AT&T Samsung SGH model, and here are the steps I followed to unlock my phone:
- Once I switched on my phone with my new SIM card I got the message “Invalid SIM Card Network Lock”
- Then I simply turned my phone off and removed the new SIM card
- You don’t have to close the phone, but simply turn the phone back on and then type in the unlock code hit the enter button and my phone is unlocked
This is normally the best way to even unlock a Nokia N76 cell phone. Another important point to remember is to type the unlock code exactly as it is given to you as there is no room for mistakes here. Rather take your time and do it slowly to make sure you get it right first time round. Not all cell phones operate the same way. So, it is best to first get the instructions for you particular model.
