Please help me check if my iPhone5 is locked

If you put the mobile phone card directly, it can be used, and it is unlockless.

The locked version of iPhone5 must be activated before it can be used, otherwise it will not be possible to insert the mobile phone card of the domestic operator, and it will prompt that only the mobile phone card of the specified operator can complete the activation operation after insertion.

The steps to activate are as follows:

It is not immediately available after activation, and the phone is in a state of no signal. The phone then searches for a signal, and after about 30 seconds, the location of the mobile phone signal bar appears "roaming", indicating that the phone is roaming. Wait about four minutes: A "China Mobile" sign appears at the top of the screen.

After that, you can dial up, but there is no "e" sign that the network data is enabled, and the attempt to connect to the network fails. After turning on "Cellular Data" in "Settings" - General "- Cellular Data Network", it still doesn't work. There is a "roaming" function below, this function is only available on iPhones that support CDMA standard, after entering, turn on the "voice roaming" and "data roaming" functions, and after 5 seconds, the "e" network logo appears.

At this point, the network connection is successful.

At this point, the locked version of iPhone5 has been activated, and functions such as Internet access can be realized.

There is a lock means that some operators sell contract phones at low prices, such as a 2-year contract, which requires users to use a certain ** of this operator within 2 years, and at the same time lock the mobile phone can only use the SIM card of this operator.

Unlocking can be flashed or carded, etc., the impact is not particularly large, and it can be used.

The question is that you go to ** buy the so-called locked?

There is a locked version of the iPhone:

Yes, you can only use the SIM card specified by its ** carrier. If you want to use the SIM card of another ** company, you need to unlock the iPhone. (This means that this kind of iPhone has not been unlocked.) ）

So the "lock" of the iPhone has a locked version and an unlocked version means: not whether the iPhone can be unlocked (the iPhone can definitely be unlocked with the SIM card of any ** company), but whether the iPhone needs to be unlocked (if you want to use the SIM card of another ** company, unlock it.) ）。

Sometimes, the company says that it sells a locked version of the iPhone, which mainly means that you want to sign a 24-month or 18-month contract with him. And if you sign a contract to buy the iPhone and want to use the SIM of another ** company, you can also unlock it to achieve your goal.

iPhone5 has a locked version that can be unlocked with a card, but this is only temporary, and if you want to unlock it permanently, you have to make an official solution, but the cost is not low.

**, there are some merchants, they have special channels, they can be unlocked directly, and it is permanent.

My iPhone4 was unlocked in July last year by the AT&T operator in the United States, and I have been using it until now. When it was unlocked, yes, now it's used all the way.

It is recommended to use the operator's unlock, that is, the operator sends your IMEI to Apple's server, and then the Apple server talks about the data of your machine's corresponding IMEI in the database, and opens the permissions of other frequency bands.

In response to the above questions you raised, the following are answered one by one:

A1: Jailbreak is required to unlock the card with software. The card unlock part can be unlocked without jailbreaking. Jailbreaking can give you access to install the software and unlock the software and dependencies you need. This method is not recommended, and if you accidentally update it, it will be miserable.

A2: Software unlocking, card unlocking machine connection**, SMS may be slow.

A3: After the software is unlocked and the card is unlocked, the upgrade will die immediately.

A4: If you buy the locked version directly, it's hard to say what the boss will do.

If you buy a locked version of your iPhone, you can do this: people who use China Unicom and China Mobile can directly buy a locked phone from an AT&T operator, and then activate it with AT&T officially, so it's okay to upgrade it casually. Permanently available.

If you have a telecom number, you can buy Verizon's unlocked version directly.
