If you've tried to enter the lock code more than three times, you'll need to enter the PUK code - if you've tried to enter that more than 10 times, the SIM card is unusable, and you'll need to contact your provider.

You will have to take it to a mobile shop to have it unlocked. If you have tried to many times you can not unlock it without taking it to one.

Ive tried entering the master code but it doesnt work. before this i wanted to reformat my phone using the *#7370#, it then asked for my lock code. i entered the default lock code but it does not work.....


turn off your phone.when you switch it on hold the *,green and 3 button simultaneously .remember *(star),green and 3 button. hold these three buttons and switch on your handset, it will be formatted without the lock code option.
good luck

Im just buy SE m600i second hand,now i want reset m600i phone lock,does anybody knows how to reset it?


The code is usually 0000 or 1234. If none of them working then reinstall firmware using SEUS. This will also wipe out everything from phone so do back up before update.

Master reset code for M600i


The security code can be changed and still be in effect with all locks off. Try 6 0's (000000). I didn't see that listed in the things you've attempted. If its been changed, the only way to determine that is to contact the previous owner and see if they remember it. If not, it will have to have all new software written to the phone. Basically like a format / reinstall.
