Can foreign 3G phones be used in China?

Yes! 1.Yes.

2.The answer is that it works, but some features are not available.

3.If the phone is suitable for China's 3G standard, you can use China's 3G network.

4.There is no exact time when China will be able to open 3G, but by the time of the 2008 Olympic Games, China's 3G will definitely be available.

3G is not yet widespread in the world, and fewer than 2 million people are using 3G mobile phones worldwide.

3G standards include: TD-SCDMA and HSDPA (over 3G) proposed by China

1.There is a plug-in card holder.

2.Some can be used, and some need to be decrypted, like Japan's Soai's v8003At present, it is uncertain, if the country is building our domestic TD-CDMA network, now foreign ones can not be used, mainly WCDMA in Europe and CDMA2000 in South Korea (the current national policy seems to be inclined to our domestic TD-CDMA, but it is not ruled out that the possibility of building WCDMA network will also be built).

4.There is news from the Ministry of Industry that it will be before the end of 06, and it is certain that it will be used before the Olympics. (Personally, I think the timing must have been 08 years ago, or 07 years at the latest, and the network needs to be operated to meet the Olympics).

After China opens 3G, there will be three standards running at the same time: WCDMA, TDSCDMA and CDMA2000

Among them, TDSCDMA is China's own standard and will be the first to run.

The other two are foreign standards, and if you buy a 3G mobile phone abroad, it should be WCDMA or CDMA2000 standard.

Wait until China has opened the WCDMA or CDMA2000 standard, and then you can use your mobile phone.

If you bring it directly from a foreign country, you can only use it if you unlock it.

Because ** is frequency-locked.

I have the same issue, thanks. But I heard that it can be used by changing the frequency, but I don't know if it's true.

Mobile phones can be used when they go abroad.

Domestic mobile phones go abroad, most of them can be used normally, whether you are Apple or Android, but it should be noted that there are some software that may not be able to be used after going abroad. Or some software you can use in China, but you can't use it after you go abroad.

In addition, it is recommended that you do not cancel the Chinese mobile phone card when you go out, and keep a minimum consumption**, because your WeChat Alipay or Chinese bank card needs to be bound to the mobile phone, and if you cancel it, it may cause inconvenience to yourself.

The methods for cleaning up the memory of the phone are:

After the file management, you can see that there may be a lot of folders in it, we don't know what it does, here you can search for the first folder is the buffer folder, cache but the cache contains some cache files, we can delete it directly, these caches can be deleted directly after selecting them at home.

The second folder is to share with you the deletion of the backup folder,backupWe enter backu to search, these files are some backup files of the system,Basically, it has no effect,For example, like some software or some data are some backup data,If we click on it, we can also delete it directly,Click on the right side after selecting all to delete it directly。 <>

The network is different!! China's 3G is different from abroad.

It depends on which network standard your 3G mobile phone is used and which operator's mobile phone card you are using.

For example, if your 3G mobile phone is WCDMA standard, it supports Unicom 3G, you can use Unicom 3G card, and after Heng Jian opens the branch infiltration international roaming function, it can be used normally in the United States, and the specific international roaming tariff can be here.

View. If it is a 3G manual hitch machine of another operator, you can contact the customer service of the corresponding operator for information. Understanding and preparing before you go abroad can save you a lot of trouble.

The unlocked mobile phone can be used, if it is unlocked, you can directly insert the card to use, if it is locked, you need a card to use, generally buy the unlocked version directly when purchasing.

For example, the American version, the Japanese version or the Hong Kong version of the Apple hand-buried hopper machine can be used in China if it is an unlocked machine, and the locked machine may need to be stuck before it can be used, such as CDMA is Telecom 3G, WCDMA is Unicom 3G or FDD-LTE4G standard.
