The Samsung J260T1 binary 3 unlocking was performed, in the registry it indicates that the work was done but the phone remains the same, for this reason the unlocking was performed again the next day, being fine, but the system charged twice the credits. You can verify and make the refund please, I send the records of the operation and the user my Z3X
