On iOS 12.3 iPhone Lock cannot change the ICCID code directly on the phone and this is a fix

Apple increasingly strong hands with the network lock iPhone (iPhone Lock). More than 1 month ago, Apple has changed the activation mechanism, so that iPhone Lock can operate to have a SIM paired in the machine, not simply replace SIM like before.

In some cases, iPhone Lock must update to the latest version of iOS 12 to activate so some older devices such as iPhone 5 or 5c cannot be used because it cannot be upgraded to iOS 12.

On May 14, Apple officially released iOS 12.3 update with some new features and software bug fixes. However, this latest update does not allow iPhone Lock to change the ICCID code directly on the device to activate it on the main screen.

The ICCID is a 20-digit sequence of numbers entered into the machine to 'trick' the system that is using the SIM pairing of the right operator, from which the iPhone Lock can be activated.

In order to overcome the situation of not changing ICCID code directly on the activation screen, users in Vietnam can insert SIM cards to international machines and exchange SIM applications directly in the settings, then reinstall them to Lock machine to activate.

Currently, when using iPhone Lock is getting more difficult than before (complicated use process, now requires both international iPhone to activate), the price of this device has dropped sharply in Vietnam market. iPhone XS Max Lock is only about 17 million, before it cost more than 20 million.
