A friend of mine bought an IPhone 7 Plus here in Brazil and is blocked.
The IMEI is: 355374080948136
How can we unlock to use?

Depending on how the original owner bought the phone they will need to have it unlocked. You would have to be a T-Mobile customer in the US to unlock it. Again you need the original seller to handle the unlocking process. If this phone was purchased on a third-party reseller site you may need to request a refund.
