SOURCE: my samsung beat t 539 say phone locked return for service

Try this, I unlocked mine after forgetting my password; it should work, since it's samsung universal!!!

Just take in mind it will RESET the whole phone, all your contacts, txt's and photos or music will be deleted!! but if you want to unlock it here you go!!

*TAKE the sim card OUT
*Turn the phone on
*Enter : *2767*3855# = Full Reset (Caution every stored data will be deleted.)

I forgot my n72 lock code

Have you tried bringing your phone to Nokia Service Center? Cause every unit has a default lock code matched to your IMEI in case you forgot yours. Try asking them for the code.

If it hasn't been changed, the default passcode is 00000000. It also may be SIM locked, in which case you'll have to contact one of the companies that unlocks these. I recently had a phone unlocked by It's not a free service, but they have very good support. And most the time you don't have to mail your phone out. There is no universal code to unlock a SIM locked phone - as it's tied to the original service provider. If you don't know who provided service to the phone, you probably will have to ship your phone to them to get it unlocked.

Phone is locked and asking for a PUK Code. Says

HI If you are asking for pin contact your service provider , he will give you a default pin . If you try pin more than few predefined no of times your phone will ask PUK code which can also be given only by your service provider which is specific for each and every mobile number . Donot try PUK code many times or else your sim will be blocked and you will need a new sim.
Contact your sim customer care department over phone. Its free of cost to get the pin or puk no.

Go to the nearest service outlet of your service provider they can also help you.

There is no other go than the above procedure only your service provider can give it nobody else in this world nor any software.
