That's because you need an unlock code in order to unlock your phone. When you will receive the code and the unlocking instructions you will be able to unlock it yourself. Here is how you can use your phone not only in Brazil but everywhere in the world!

    The benefits of getting an unlock code for your Samsung tablets and Samsung phones include; benefits such as freedom to move about the country and world more freely, flexibility for the user, as more phones get unlocked. The current wireless carriers would have to compete more efficiently with their competition by offering more services and have wireless plans that are more reasonably priced for their customers, also unlocked mobile device have an increased resell valuehttp://www.getmymobileunlocked.com have great customer service and great prices.

All SIM unlock codes are tied to the particular device IMEI and are carrier specific. The request for that code would need to be made from the carrier that the phone was originally manufactured for.
But there are websites which you can trust to get the codes.
The phone has got limited number of attempts where in you can enter the MEP code. Hard lock will come into play when there are no attempts left in the cell phone. This should help you, http://unlockgenie.com/
