What is the difference between an iphone without a lock and a lock

The meaning of lock is actually network lock, which is a way to restrict users from choosing a carrier. The iPhone with a lock version is a network lock, that is, it is bound to the operator. If you want to use a locked iPhone, you need to jailbreak it first and then unlock it.

Only through this two-step process can a locked version of the iPhone be able to use another carrier's card.

There is a locked version of the iPhone, such as the American version of AT&T, the British O2, such a mobile phone can only be used by inserting the SIM card of the corresponding operator, and it cannot be used by inserting other cards. Normally, the purchase of this type of iPhone is through signing a 1 2-year network access agreement with an operator, binding a credit account to promise how much to spend a month, and buying the phone at a discount or giving it away for free. In fact, in this way, the cost of buying an iPhone has been converted into the phone bill of the corresponding operator.

Unlocked version: The unlocked version is also called the official unlocked version, such as the unlocked version of Hong Kong or the United Arab Emirates (Hong Kong also has Hutchison's "3" customized version of the iPhone).

This kind of mobile phone will generally be relatively high**, but the advantage is that the SIM card of any operator can help the iPhone activate smoothly and be able to use normally. The unlocked version allows you to upgrade the firmware at will, and you don't have to worry about signal cracking. For them, they only need to be jailbroken, they do not need to be unlocked.

Note: If there is a locked iPhone, whether it is unlocked or not, the baseband will be upgraded when upgrading the firmware (the online baseband upgrade method is only suitable for specific devices and specific systems). As soon as the baseband is upgraded, the phone returns to an unlocked state and needs to be unlocked in a new way.

Therefore, when buying an iPhone through unofficial channels, you need to figure out whether it is locked or unlocked. If you buy a machine with a locked version, you should also carefully upgrade its firmware.

I often see people discussing Apple's locked version and unlocked version, what is the difference between them?

If you choose no lock, that is, you get the phone and press the middle button, there will be a slide to unlock, this does not require a password, if you choose a lock, you need to press the password or use your fingerprint to open.

The difference between iPhone with lock and no lock is: the definition of the two is different, the two are very different, the carriers they support are different, and so on.

1. The definition is different: an iPhone with a locked phone is a machine with a network lock, which is also called a contract machine. iPhone unlocked machine is also called the official unlocked version of the mobile phone, such as the common national bank, Hong Kong version, and American version of unlocked, unlocked machine is a machine that is not bound to an operator, and can be upgraded at will.

2: ** Difference: iPhone has a lock machine is an old foreign foreign operator contracted machine, and even foreign countries play the slogan of buy one get one free.

In China, the unlocked machine even has to spend about 5000-7000 yuan. Therefore, there is a machine like a locked machine, once the contract is terminated, ** is very cheap, the larger the memory, and the greater the price difference without lock.

3. The supported operators are different: the iPhone is a machine with a network lock, which is also known as a contract machine, and it is a machine that has signed a contract with a foreign communication operator. Its appearance and hardware are no different from the national version of the machine, the biggest difference is which telecommunications operator he signed a contract with.

There are no restrictions on iPhone without locking.

1. Differences.

The iPhone has a locked version**, which is equivalent to the contract signed with the carrier. Generally, it is converted into a monthly phone bill, and if the monthly consumption is reached, the phone bill can be used according to your needs every month after the contract expires. However, it is still only possible to use the SIM card of the bound carrier.

The unlocked version of the iPhone ** is more expensive, in Chinese mainland is basically a locked version of the iPhone, the unlocked version of the iPhone in China only in Hong Kong.

2. Differences in use.

The iPhone phone has a locked version and cannot be upgraded with the official latest system in time, even if it is upgraded, it needs to be unlocked again. With each upgrade, a file in the phone called the "baseband" is also upgraded, making it impossible for the phone to recognize previous unlocking and jailbreaking procedures, and it is impossible to downgrade.

After jailbreaking the unlocked version of the iPhone, there is no need to spend money to buy software and games. The unlocked version can be said to be a novice that won't turn brick no matter how you play it.

There are two types of iPhones, locked and unlocked. The locked version is to add a network lock, that is, to bind the operator, such as the American version of AT&T, the British O2.

There is a difference between locked and unlocked iPhones.

Locked and unlocked are for each country, because the foreign network system is different from the domestic one, so foreign Apple in China some ** cards can not be used, unlocked.

1. The scope of application is different: the scope of application of the locked version is small. The spineless lock version has a wide range of applications.

2. The signal is stable and qualitatively different: the locked version has strong signal stability. The lock-free version has weak signal stability.

3. The performance of the system is different: some of the locked versions cannot be judged to upgrade the system. The unlocked version can upgrade the system.

The differences between locked and unlocked Macs are: different operating card usage rights, different **, and different operator contracts.

1. The use authority of the operation card is different.

The unlocked version of the Apple phone can use any card of the company, and the locked Apple hand punch machine cannot update the system firmware at will.

2. **Different.

There is a big difference between the locked machine and the unlocked machine, and the locked machine is relatively cheaper.

3. The contract of the operator is different.

A locked machine is a machine with a network lock, also known as a contract machine, which is a machine that has signed a contract with a foreign communication operator. The unlocked machine does not have a network lock and does not have a contract with the operator.

The concept of Apple lock

The meaning of lock on Apple mobile phone is network lock, which is a way to restrict users from choosing a carrier. The locked version of the Apple mobile phone is to add a network lock, that is, to bind the operator. Most of the locked mobile phones in China are contract phones of operators from abroad, so they have a very strong network lock and cannot use the mobile phone card of the domestic operator normally.

If you want to use a card from a non-designated operator, you must jailbreak it first, and then unlock it, or use a card to assist in use. Then the iPhone with a locked version can use the card of another carrier. An Apple phone with a lock cannot be dismantled and emptied of the new system firmware at will.

There are also restrictions on use in other countries. But an Apple phone with a lock is cheaper than an unlocked one.
