Tablet Lock Code

Hi

I have Anti-Theft enabled on my tablet, I tried to switch the sim card and now I have the “this phone has been lost or stolen” siren going with the unlock code to be entered, I cannot remember the code!!, tried to unlock the tablet with the sms command but obviously the code is wrong, then I logged on the web access and the tablet is not listed as one of my devices.

How can I unlock the tablet?

Did you set a recovery number into Anti Theft ?

also please remember the PIN is max 6 digits so try only first 6 digits of PIN
