Usually when a phone is purchased through a network carrier, the phone is by default locked by the specific carrier. It is usually done to bind the user to use only that specific network. But if a user has to travel across border, the phone would become non functional due to the lock that has been put by the carrier. Back in the time unlocking a phone was easier through unlocking software but now Apple has put certain restrictions on unlocking software and it is not possible to get the phone unlocked easily. However, MyCelCare specializes in getting your iPhone 6s plus unlocked and get it listed on Apple’s official record of unlocked phones. We only need to have your phone’s uniqie IMEI number in order to get it listed in the record and it would still be unlocked even if you upgrade iOS.
