The iPhone bought in China is used abroad

Yes, Unicom iPhone is not locked on the Internet, and it can be used in the UK3G parallel goods can also be used, but like the American version needs to be cracked, and the Hong Kong version is not needed.

1. First of all, the bare iPhone (unlocked) bought in China can be used when brought back to the United States. However, China has a locked version and an unlocked version. The unlocked version can be used directly, and the lock needs to be unlocked, and the current method is to unlock it with a card, which is relatively stable.

2. After flashing the mobile phone, the function is the same as the original mobile phone, and the jailbroken mobile phone can even install the mobile phone software released by other unofficial channels to expand the software function. For example, MMS, SMS**, copy and paste, mobile phone firewall and other functions, these functions need to be developed with the underlying support of mobile phones, while Apple has not opened the relevant interfaces, and prohibits similar software from being sold in the App Store, so it can only be used on jailbroken mobile phones.

There is no card lock abroad, but it is not very expensive, and it is very cheap.

If you buy at Unicom, there will be a very expensive phone bill, and you also need to sign a monthly minimum consumption agreement.

iPhone 3GS Zhongguancun bare metal** is not high, in short, there is no need to buy it in China.

No problem, the hardware of Apple's products is all the same.

As long as it's not a locked or contract machine, you can use it.

1. If it is the American version of the unlocked iPhone, it can be used directly in China;

2. However, generally in the United States, the purchase is a contract machine, which has a network lock and needs to be unlocked with a card. You can buy the card online and follow the unlocking tutorial to unlock it, and you can use the domestic mobile phone card.

OK.

Chinese mainland Bank of China's iPhone 11 Pro 11 Pro Max SE (2020 model) The version sold in Chinese mainland and the United States has exactly the same network frequency band. The 4G 3G band network support is exactly the same as that of models sold in the United States. However, the US version of the Bank of China will have a bit of a problem with the lack of support for B28, and the experience of using operators in Europe, Australia, Japan and other countries and regions will decline slightly.

Introduction

As for 4G, 3G is of course no problem. China's National Bank iPhone is unlocked, unrestricted, and the carrier support is the same as that of the American version in the United States.

There is basically no difference between iCloud, App Store and iTunes in terms of software features. The same devices in the Bank of China can log in to the US ID to use the APP services in the United States, and there is no obvious difference between them and the local US devices in the United States, just like Chinese users can use the China APP when they buy the US version of the mobile phone.

If it's a contract machine, it can't be used, but if it's Apple's bare metal, it can be used in China.

There are two kinds of foreign Apple mobile phones, one is the contract phone, AT&T and other operators sold from $199 mobile phones. This one comes with an operator lock and must be used with the carrier's card. If you bring this kind of Apple phone back to China, you can unlock it with a card, but when you upgrade the system, you need to upgrade the baseband, and iMessage and FaceTime cannot be activated.

The other is Apple's bare metal, which can be purchased in foreign Apple stores, and the bare metal is unlimited. Moreover, iPhone6 supports the whole network version, so you can use the card of China Mobile Unicom Telecom. Since the previous version of the Apple mobile phone generally uses China Unicom and Mobile, but the telecom needs another version.

If you bring it back from abroad, you first have to see if there is a lock version, if there is, it is recommended not to buy it, it is very troublesome, and you have to use the card sticker.

If it is an unlocked version, it can be used, but only the domestic warranty is provided to the Bank of China, Unicom contract machines and some Hong Kong banks with good RP.

Think twice, now there are only about 4,003 in Hong Kong, so it's better to buy in Hong Kong.

Yes, but the machines customized by foreign operators need to be unlocked before they can be used.

It works !!

Apples abroad are cheap!!
