Hello, everyone. I'll answer your questions. Apple US version has lock and no lock is what it means, Apple US version has lock is what it means, many people still do not know, now let's take a look at it!

Answer:

1. Baseband encryption in mobile phones. When American operators sell contract mobile phones, they use the method of buying mobile phones to send calls, that is, adding network locks on mobile phones, that is, binding operators. These phones can only be used by inserting the SIM card of the corresponding carrier, and cannot be used by inserting other cards. The network signal can only use the mobile phone number of the contracted machine. Inserting another phone card won't show any services, so lock and encrypt the phone.

2. The difference between locking and unlocking Apple:

3. Compared with the locked version, the unlocked version can be upgraded at will without the restriction of the operator, and there is no need to consider the problem of signal cracking.

Compared with the unlocked version, the locked version is cheaper but the signal is unstable, and some locked phones cannot upgrade the system.

5. The US version of the lock can be regarded as a contract machine, and the operator uses the SIM card provided by other operators to prevent the customer from breaching the contract, thus setting the machine card binding for the mobile phone. No lock.

This is the end of this article, I hope it helps everyone.
