I have written this post to explain how to unlock Samsung mobile phone without any box and cable. Sometime we get Samsung mobile with phone lock. If you are an end user or a mobile repair professional, it will help you. This trick will work specially on the touch screen phone like Samsung Champ, Champ duos, Chat etc.
- Switch off your phone.
- Now switch it on again.
- On the phone lock screen, click on SOS call.
- Once clicked on SOS call, confirm SOS calling by clicking on Yes.
- While SOS call is going on unlock and use the on screen keyboard (If touch screen phone).
- Now dial *2767*3855#.
- The call will be disconnected automatically and phone will be restarted automatically.
- All done!! Your phone is unlocked now. Enjoy!!
