Well if you set up Anti-Theft successfully, you had to enter the numeric password. Just enter it here as well. If it’s not working, you can always try 0000 (default password), but I’m afraid it won’t help.

I tried it but not able to access , i am totally confused . any another option if you it will be a great help .

Well, did you try inserting the old SIM back?

Filip

yes , right now old sim is in my phone .

Filip i am waiting for your response , please tell me now

I suppose siren is off right now and you can access your phone. Does the password work now? Are you able to access the Anti-Theft interface?

Sorry but my own sirens are ringing and this user has most likely found an S3 or stolen one with the App its good to know its working! Hahahaha
