Why can t Apple 7 use telecom, how to solve the problem that Apple 7 can t use telecom card

Bank of China: The iPhone 7 model is A1660, and the iPhone 7 Plus model is A1661, both of which are full Netcom.

Hong Kong line: iPhone7 model is A1660, iPhone7 Plus model is A1661, although the model is the same as the Bank of China, but the official website does not indicate that it supports CDMA, currently supports Mobile Unicom 2 3 4G, Telecom only supports 4G. Whether it supports telecom 2G and 3G needs to be confirmed by actual testing.

US version: iPhone7 Plus in addition to A1660 1661 version, also has A1778 A1784 version, A1660 1661 version supports full Netcom, A1778 A1784 version does not support telecom 2G 3G, supports telecom 4G.

Japanese version: iPhone 7 model A1779, iPhone 7 plus model A1785, both support full Netcom (note: both phone models are exclusive to Japan, may use Sony Felica payment plan instead of Apple Apple Pay).

Summary. 1. Apple 7 can't support telecom cards mainly because the purchased mobile phone network mode does not support telecommunications, mainly because of hardware problems, which cannot be solved; 2. You can buy the Apple 7 of the National Bank or the American version of the full Netcom, which can not only support telecommunications, but also support mobile and Unicom.

You can buy the Apple 7 of the whole Netcom or the American version of the Tuna National Bank, which can not only support electric messaging messages, but also support mobile and Unicom elimination.

Not supporting it is unsolvable.

Hello, may I ask the American version of Apple 7puls can not use the telecom card, how to solve it.

I'll check it out. Good.

A: Check for apps such as firewalls, which may have turned off software self-start or running in the background.

There's no firewall.

The common problem of 7P is the baseband problem, many of which have no signal directly, and the upgrade system should be able to solve it.

Was there before?

Haven't used telecommunications before.

Both China Mobile and China Unicom can be used, but telecom cannot be used.

That may just be not supported in the first place.

Or there is no local signal.

In both cases.

Oh thanks. It's okay.

Method steps.

What should I do if there is no service in the display of Apple 7P Triple Play Telecom Plug In, first take out the mobile phone card, check whether there is a problem with the mobile phone card, or insert another telecom card to detect whether the mobile phone card cannot be used, resulting in no service on the mobile phone.

The Hong Kong version of iPhone7 wants to support the telecom card to use the card sticker,iPhone mobile phone each country has a little restrictions,My personal iphone after the card sticker signal is always up and down,You can call**But there is no network。 Later, after opening Telecom Volte and changing a card again, it can be perfectly solved, but you can't switch on and off the phone, and it is not good to turn on the phone after charging without power, and it is not good to give up in the later stage, it is recommended to use a mobile Unicom card, which is perfect.

In this case, it is very likely that the iPhone may not be a national bank, but a version of the Hong Kong version or other countries. Some versions of the Hong Kong version or other countries do not support full Netcom.

You can try the method: in the voice roaming options in the settings, dial *228 on the call interface to see if "China Telecom" will appear

If it still doesn't work, the user can find a mobile card to plug in the mobile phone, if the call voice function is normal, then it can be basically determined that the mobile phone is not full Netcom, and can not support the mobile communication service of the telecom card.

It's because your mobile phone was brought in from abroad, not the full Netcom version of Apple, and the specific solutions are:

1. First of all, we need to open the Apple phone, find the "Settings" function, and click to enter;

2. After the settings are counted, then click on Cellular Network;

3. Click on the Data Roaming option.

4. At this time, you can see the "Voice Roaming" function, and choose to turn it on in the blue box at the back;

5. At this time, dial *228 on the call interface to see if there will be "China Telecom", if it is supported, it proves that Telecom is fine.

6. If this doesn't work, you can borrow a mobile card to try it, whether it doesn't support the telecom version. Then I had to go out first and then buy a full Netcom version (American version, Japanese version, mainland licensed, Macau version) and set it up.

Hello, look at what version of the mobile phone is, if it is the Hong Kong version, you can't use a telecom card.

According to the official website, the unlocked version of the Hong Kong version of the iPhone 7 for public sale can support the 2G 3G 4G network of China Unicom, China Mobile and Telecom, which is commonly known as full Netcom. However, since there is no CDMA operator in Hong Kong, the telecom network cannot be used by default.

The reason why Apple Seven can't use telecom cards:

The mobile phone card is not plugged in properly, and the contact is poor.

The mobile phone card, card slot or mobile phone terminal is damaged;

Here are some things you can try:

Turn it on and off and restart it to test it.

Reseat the mobile phone card and check whether the card slot is loose or deformed.

Test whether the SIM card or terminal is faulty.

Verify that the status of the SIM card is normal.

The ** cards sold by the current operators are basically full Netcom, and they can be used in any mobile phone. It's just that some mobile phones are custom-made, and which operator uses which operator's custom.

The Apple 7 phone you said should be able to use a telecom card, unless your Apple 7 is a custom machine.

The poor mobile phone signal is because the signal will be affected by various factors such as terrain, landform, and high-rise buildings during the propagation process, and if you are in a relatively closed place, the signal will be affected. You can restart your phone, or change the SIM card to a family friend's phone to try again, and see if the signal of other connected users around you is working. If you still can't solve your signal problem, please contact the local customer service for consultation.

Based on the information you provide, the common causes and solutions for your phone not receiving calls** are as follows:

Check whether the mobile phone is in arrears and shut down, and it is recommended to pay and recharge;

Check whether the phone is set to call forwarding, turn on airplane mode, call restrictions, etc., and it is recommended to cancel and try again;

Check whether the function or signal of the mobile phone is normal, it is recommended to change the mobile phone or location and try again;

If you cannot use it when roaming to other places, it is recommended to check whether the local network signal is normal and whether the number has been activated for roaming permissions.

Try restarting or changing your phone to see if you can make calls**;

Bring your mobile phone card to the local Yunchun business wax ruler hall for testing or replacement of your mobile phone card.
