How can the US version of Apple 4 be used normally if it has a lock?

1. Be very careful when you start, and cut another piece from the already small SIM card. Nail clippers are the most convenient tools. If you have confidence in your hands-on ability, sharp scissors are also an alternative.

2. After cutting the card, put the card on the card slot, pay attention to the black circuit block facing up, and then put the cut SIM card on it. You can't put it in your mobile phone now.

3. Turn off the phone and turn it on again. When the screen lock appears again, quickly open the screen lock and push the installed card slot into the phone. Please remember to cancel the screen lock password, because it will be too late to unlock the screen and lead to failure. )

4. Wait patiently for a while, and a dialog box will pop up on the GEVEY sticker, telling you how to unlock the sticker. You can take a closer look. Click OK, and then wait 15 seconds to enter the next step.

5. If you miss the previous step, don't worry, you can enter the SIM card application menu for setting your mobile phone, wait a while, and a prompt will pop up. If not, you can turn it off and start again.

6. After15 seconds, switch to the dialing page, dial "1 12", and hang up immediately after the call (within 2 seconds). At this time, the screen will be stuck on the dialing page for a period of time. Then you will return to the normal dialing interface. (Hint: Don't dial 1 12 in a hurry, which may lead to early failure. Be more patient and wait a little longer, even if it is slightly longer than 15 seconds. )

7. At this time, turn on the phone settings, turn on the flight mode, wait for another minute or so, and a prompt will pop up that the SIM card is not installed. Ignore it and turn off the flight mode.

8. Finally, there will be a prompt that the SIM card has failed. Continue to ignore, wait patiently for dozens of seconds, and the signal appears. The brick machine was saved.

After using the card sticker, the cards of China Mobile and China Unicom can be used normally, with normal network function, normal 3G function and normal call function. In short, all functions can be used normally.

Precautions:

1. If the prompt of "Operation Failed" appears, or the situation not mentioned above, please shut down immediately, take out the card and start again.

2. If it fails all the time, please check whether there is contact between the card sticker and the metal part of the SIM card chip. If there is unfortunate contact, you need to change the SIM card and start over. Sometimes, even if there is no connection, it will always fail. There is a 1% probability that there is something wrong with your SIM card. You can try to replace the SIM card.

3. Because the card is unlocked, FaceTime will send an international SMS when registering. If you want to use this function, you have to open the international SMS function in the business hall, and the registration will be delayed because of the international SMS.
