Apple 6s can't make phone calls, but can send text messages and surf the Internet. What happened?

First, the problem of signal or telephone operator.

1. Sometimes in some places where the signal is not good, we will encounter such a problem, and we need to redial if the call fails. This situation is generally caused by the current bad signal. Just redial in another place.

Second, turn it off.

1. If it's not a signal problem, you can try to turn it off before turning it on. You can press and hold the power button of iPhone, and when the power off option appears, you can turn it off by sliding.

Third, insert and dial the calling card.

1. If turning off the phone doesn't solve the problem, you can try dialing the calling card again. You can pick up the card by using the card pick-up pin or other similar items that came with the iPhone.

2. Then, there is a small hole on the right side of the iPhone dedicated to card retrieval, and the calling card can be popped up with the card retrieval pin. After you take it out, clean the phone card, put it back, and finally try again to see if you can make a phone call.

Fourth, restore network settings.

1. If the above methods still can't solve the problem, you can try to restore the network settings of iPhone. Click the General column in the settings list.

2. At the bottom of the general list, find the "Restore" column, and then click Enter.

3. Then click the "Restore Network Settings" option in the restore list.

4. Then click the "Restore Network Settings" button that pops up at the bottom to confirm the restoration. After the system is successfully restored, let's see if we can talk normally.

Verb (abbreviation for verb) hardware failure

1. All the above methods have been tried. If it still doesn't work, you can try another calling card. If it is ok to change the calling card, it means that it is a problem with the calling card. You can ask the telephone operator to reissue the card.

2. Of course, if changing the calling card still doesn't solve the problem, it is likely that there is something wrong with the hardware of the iPhone. It is recommended to go to the local Apple for authorized after-sales inspection.
