How many versions of locks does Apple have?

The most common iPhone locks are American version and Japanese version!

The American version of iPhone has a lock: it is divided into S version, V version, A version, T version, xf version, att version and so on. For example, the iPhone X (S version for short) of American sprint operator can only use its own authorized sim card. If you use another operator's card, you will switch to the activation interface, and finally the activation will fail. This is the so-called network lock!

Among them, the S version is the most stable machine of sprint operators, and the model is A 1586, which is full netcom.

V version is the machine of Verizon operator, which supports Unicom's 4G and mobile 2G.

Version A is the att operator's machine, which supports Unicom 2g, 3G, 4g, mobile 2g, 4G.

The Japanese version of iPhone has a lock: it is divided into three versions: au, s b and du. The first two versions can realize triple play with cards, and the du version can reach the 4G network without cards, but it has a disadvantage that it will deduct the cost of international SMS itself! The solution is to cooperate with the card to unlock, and the network is also Mobile Unicom 4G.

There are also some reprinted unlocked iPhone, and some support triple play 4G, such as the S version of the US version and the triple play unlocked version of the Japanese version; Some support two networks of China Unicom's 4g, such as Korean version, American version and Australian version. There is not much difference between these versions, but the versions are different and they are sold to different countries.

The above is the classification of iPhone with lock. Is everyone clear?
