Japanese version iphone4s unlock and American version iphone4 card which to buy

It's best not to buy it.

Analysis of the reasons:1Whether it is the Japanese version or the American version, as long as it is unlocked and with a card sticker, it cannot be warranted in China, and can only be returned to the country of origin for warranty (the Japanese version of the return to Japan Apple after-sales warranty, and the American version of the back to the United States Apple after-sales warranty).

2.The Japanese version is usually unlocked, and the jailbroken device will not be officially protected by Apple, and it will be repaired at your own expense if something goes wrong.

3.It is very inconvenient to unlock the American version of the card, because every time you upgrade, the card will be scrapped, and you need to replace the card to re-unlock it.

4.Neither supports the 4G network, unless you buy an apple peel that supports the 4G network.

Let's just put it this way, both have advantages and disadvantages, and the Japanese version of the 4s upgrade may be locked again. And 4 buy a lot of refurbished machines now, after all, the official website has been out of production for a long time, so I still hope you spend more money to buy a Hong Kong version or a national bank, with comfort.

It seems to be a telecommunications machine.,Unicom Mobile can't use it.,I've used 4 with a card.,Basically doesn't affect normal use,Occasionally, the signal will drop,Apple's sales routine is,Constantly upgrade the iOS system,And the normal program can't be downgraded,Rise higher and higher,But the configuration requirements are getting bigger and bigger,Until you can't get stuck in the card,Change to a new machine。 I'm now feeling very stuck in Hong Kong 4, and the plug-in is a little more.

Buy the number,I have a 16G Japanese version of 4S,The Japanese version has begun to rise in price,Gevey's official website plaintext card sticker will come out immediately,As soon as the card sticker comes out,It's just right to start now.,The tutorial for writing a card is very mature.。 Communicate q 852507154 yourself**, lest you say advertising. Oh.

1) It cannot be unlocked without the card at this time.

2) The biggest disadvantage is that you have to go through the cumbersome activation steps every time you shut down, restart, or plug and unplug the SIM card. Of course, if you are familiar with it, it is not very cumbersome. But now the real original card on the market is rarely more than 200, and there is a kind of high imitation of dozens of dollars, but it is easy to have no signal, no service and burn card.

3) Both 3G and mobile cards can use the Internet function.

4) The current highest version is , which can also be jailbroken perfectly.

1.The soft solution is not yet. No way to pull. The hard solution is there. Rewrite the card. Very technical. Some js may not work as well. So let's stick it up. For IP4 is not expensive.

2.The genuine signal is still very stable. It's just that every time you put the card in (reboot), you need to do some operations. It doesn't matter if you don't pull the card. Only 1 operation is required.

3.Of course. The card is to allow the card currently in the card slot to be used in this locked iohone4. (It's a bit of a mouthful.) But you should be able to understand).

4.Jailbreaking and sticking cards are two different things. Prison Break Off Prison Break. Sticker level sticker. It's best not to put a SIM card when jailbreaking.

1. No, you can't use the card, and the newly sold version can't be unlocked.

2. It is recommended that you still don't buy it, the card operation is too complicated, and if there is no signal, it will lead to re-operation, you can't enter the elevator, you can't go to the place where the signal is not good, you think about it yourself.

All 3 can be used. 4. Jailbreak is OK under any circumstances.

1. Unlock: You can use any SIM card only for the American version that needs to be unlocked, and you can't use a domestic SIM card if you don't unlock it.

2. Activation: You can use your iPhone normally (i.e., activate all functions of your iPhone), but you can't use any SIM card.

3. Jailbreak: You can install or use third-party cracked software (if you are not jailbroken, you must pay to buy the software from the official).

4. The difference between the American version and the Hong Kong version: The Hong Kong version is not locked, but the American version is locked.

5. The Hong Kong version should also be activated and jailbroken. But it doesn't need to be unlocked (it doesn't lock itself).

6. Imperfect jailbreak: When the iPhone is turned on again, it needs to be connected to the computer to turn it on. It cannot be turned on normally alone.

The official unlock is about 400 yuan, you can get it, you can calculate it yourself.

Now except for the 01 baseband, it can only be unlocked with a card! There is currently no way to unlock other unlocks! The disadvantage of the card is that it has to be re-unlocked when it is restarted and there is no signal.

I'm also waiting for an answer ... Ask for it

To put it simply, the card is an unlocking tool used by the mobile phone when it cannot be unlocked with software.

Make your phone capable of making and receiving calls with a card other than the SIM card specified by your carrier**.

For example, the current iPhone version and some Japanese mobile phones such as Sharp Panasonic cannot be unlocked, so they cannot be used back to China Mobile or Unicom cards, so we have to use card stickers to help us, so that we can use these mobile phones that cannot be unlocked.

There is a small chip on the card, which records all kinds of information, the size of the card and the size of the SIM card are the same, very thin, overlap him with the SIM card you want to use, put it in the mobile phone, and you can use it.

How the card works: For example, we want to use Japan's SH906i in China, put the Chinese card and card sticker into the SH906i, boot up, the phone will be certified when it is turned on, you put it is not a docomo card, you will read the content of the card chip first, because the chip has a record of various docomo information, so the mobile phone will mistakenly think that you are using a docomo card, so just release it, your Chinese card can be used.

In fact, it is the same as many game consoles that can't be cracked at the beginning and need to use a boot disk. The card is also known as a duplicate card, or a programmable IC card with 16F877+256 inside.

Originally, it was mainly used for the xx of satellite smart cards, and later it was used on the SIM card of the mobile phone.

Hello landlord! There is a locked version of the iphone4s will need to use the card, without the card can not be used, and when you unlock it, you don't need it, you can directly put the mobile phone card in and use it.

1.After unlocking, as long as you don't click on iTunes, the upgrade will no longer lock 2If you click the upgrade after unlocking and lock it, you can only use the card to continue to activate the unlock 3

Disadvantages of the card: you need to dial 112 to play **, and you need to dial 112 to roam, and you must turn on data roaming if you want to use a SIM card to surf the Internet.

4.If you want to upgrade, you can flash the self-made firmware, you don't need to unlock it again·· Upgrading with official iTunes requires unlocking again.

5.The card sticker is always not as convenient as inserting the card directly.

6.No matter how many times you lock it, you can unlock it with a card, and there is no such thing as a touch.

The unlocked Apple mobile phone does not need to use a card, the lock refers to the operator's version of the mobile phone, which is a contract machine, so the operator will add a network lock, if you want to use it in China, you need to use the card, the unlocked mobile phone is without a network lock, as long as the network supported by the Apple mobile phone can be used, no need to use a card.

What is an iPhone card?

The so-called American version of the unlocked, the last 99% of them were proven to be impersonated unlocked by the built-in card unlock.

The American version seems to be needed.,It's recommended to buy the Hong Kong version or the national bank.,It's also convenient to break from prison and repair something.。

If it's really unlocked, there's no need for a sticker.

Here's how:

1. After cutting the card, place the card sticker on the card slot, note that there is a black circuit block facing up, and then put the cut SIM card on it. Now we can't rush to put it in our phones. Turn off your phone first, and then turn your phone back on.

6. Finally, there will be a SIM card failure prompt, continue to ignore it, and wait patiently for dozens of seconds, and the signal will appear. The brick machine was saved!

After using the card, whether it is a mobile or China Unicom card, it can be used normally, the network function is normal, the 3G function is normal, and the call function is normal. In short, all functions can be used normally.

7. If there is a prompt of "operation failed", or if there is no situation mentioned above, please turn off the phone immediately, take out the card sticker, and start again.

If it keeps failing, please check whether the card sticker is in contact with the metal part of the SIM card chip, if there is unfortunate contact, you need to replace the SIM card and start again=. =@有时候即使是没有接触, it will also fail all the time, there is about a 1% chance that there will be a problem with your SIM card itself, you can try to change the SIM card.

It depends on your baseband version.

1. The card unlocking machine can only use 2G network, and the national machine can use 3G;

2. The card unlocking machine is prone to the problem of unstable signal;

3. The card unlocker cannot upgrade the system, and the card will be invalid after the upgrade.

The iPhone signal is not good, and if you unlock it with a card, it will be a little worse than the unlocked iPhone signal, and sometimes there will be no signal.

The national joint warranty of the National Bank, the locked ones do not enjoy the warranty in Chinese mainland, and the locked ** is cheaper than the National Bank.
