Thanks to our code servers we can get the unlocking code for the Galaxy J2 Core from AT&T USA or other network providers on the world.
The unlock code is sending to your email, you introduce it and the Samsung will be unlocked forever, without losing any information such as photos, contacts, notes, videos etc ...
Another advantage of the unlocking by IMEI is that it is from your own home, you do not have to leave the phone in the hands of other unknown people.
The version sold by AT&T United States is the SM-J260A model and the versions that are sold in Latin America are the SM-J260G
