The meaning of lock is actually network lock, which is a method to restrict users from choosing operators. The locked version of the iPhone has a network lock added, which means it is bound to a carrier. If you want to use a locked iPhone with another card, you need to jailbreak it first and then unlock it. Only through this two-step process can a locked iPhone use another carrier's card.
There are locked versions of iPhone, such as the US version of AT&T and the UK's O2. Such phones can only be used by inserting the SIM card of the corresponding operator, but cannot be used by inserting other cards. People usually call this kind of machine noob.
Normally, to purchase this type of iPhone is to sign a 1-2 year network access agreement with a certain operator, bind a credit account and commit to a certain amount of monthly consumption, and buy it at a discount or for free. Drop off. In fact, in this way, the cost of purchasing an iPhone has been converted into the phone bill of the corresponding operator.
2. Unlocked version:
The unlocked version is also called the official unlocked version, such as the unlocked version from Hong Kong Bank or the United Arab Emirates (Hong Kong also has Hutchison's "3" customized iPhone ).
The price of this kind of mobile phone is generally relatively high, but the advantage is that the SIM card of any operator can successfully activate the iPhone and can be used normally. The unlocked version allows you to upgrade the firmware at will without having to worry about signal cracking. For them, they only need to be jailbroken, not unlocked.
