Hi, I'm Aline. I live in Brazil. A few days ago I bought an iphone 7 rose gold that is blocked to use the operators in my country. In contact with apple, the same told me to send an email to request the unlocking of the device. Waiting for a response, follow the device information below: Imei: 35655908138441 Model Number: A1778 Sincerely, Aline
