Many cellular networks sell iPhone 6s with some discount offers on using their network. This is a promotional strategy to grab customers and restrict them for using their network for at least a couple of years. Usually the cellular companies put a lock on which is put to restrict the user from using any other cellular network. This becomes a problem when a user travels across the border because no network would work on the iPhone 6s. A few years back phone unlocking was easier which could be done by user through unlocking software. But now iPhone manufacturer Apple has put restrictions as the server of unlocked phones is controlled strictly by the company itself. MyCelCare luckily has expertise of unlocking your iPhone 6s by registering it on the unlocked phones server. We will only need the IMEI unique code of your phone and do the rest.
