The information you give yourself is enough :

Operator: Verizon

Model: MD277LL A

The above two can prove that the machine is the United States V version with a lock machine.

Model: MD277LL A

Modulator firmware.

The above two items can prove that the machine has been manually upgraded, and the baseband has been upgraded to the version. This means that existing stickers will not be valid. Support cards can only be purchased from X-Treasure. However, I have not heard of this version of the card that supports telecommunications.

If possible, it is advisable to apply for an official unlock.

The locks are added by the operator, and the locking machine you said can only use the card of a certain operator, if you change to a Chinese card, it can be used and can be switched on and off normally, but there is no lock.

How to distinguish whether the iphone4s has a lock? Qi translates to Shengji.

Dear, your machine is the American V version, and it is a locked machine.

query locked and unlocked methods; Insert the mobile phone card of China Mobile or China Unicom into the mobile phone, and then go to "Settings - General - About This Machine - Carrier" in the mobile phone.

1. Unlocked machine: The operator is displayed as the operator + version number of the mobile phone card, and the version number will rise with the system upgrade or operator configuration upgrade. If the mobile phone is unlocked, the operator will display "China Mobile" + version number (<=) after inserting the mobile card, and the operator will display "China Unicom" + version number (<=) after inserting the China Unicom card

2. There is a locked machine: if there is no card assistance, the signal will not be sent out after inserting the card. But many locked phones do not see the card, there will be a signal after inserting the card, which will make people think that it is unlockless, in fact, it is because the card has been welded in the mobile phone, but it can be seen through the operator, if the operator does not display the mobile card or Unicom card after the unlock, it is usually locked, if the display KDDI, AT&T and other operators, it is a locked mobile phone.

3. The above is the situation that the card patch is not installed after the jailbreak, if the card patch is installed or the card is installed after jailbreaking, it will display China Mobile China Unicom, etc., the problem is that there is no such high operator version so far, and the operator will not change after changing the card, for example, the mobile card is China Mobile, and the Unicom card is replaced or China Mobile, so whether the card is inserted or not, as long as the operator displays China Mobile China Mobile and China Unicom, it is a locked phone.

iPhone is not a network lock, for iPhone there is a difference between locked and unlocked.

1. There is a lock version.

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.

1) 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.

2. Unlocked version.

The unlocked version is also called the official unlocked version, such as the unlocked version of Hong Kong or the UAE (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.

3. For the judgment method of whether there is a lock or not. If you don't have a SIM card at hand, you can use the method of querying the model to identify it.

Open the iPhone's "Settings-General-About Machine-View Model", the information here represents some important information related to the origin, take "MD276LL" as an example, where "LL" stands for "American version", and then Google.

It must be the V version and the S version, and after the jailbreak, it can be used in three networks, and there is no jailbreak money, so you can only use mobile and Unicom.
