The mobile phone signal is very good but there is no network, and the mobile phone signal is full, b

The mobile phone signal is very good, it can call normally, there is no network signal, you can check whether the mobile data on the mobile phone has been turned off.

The mobile phone signal is good, but there is no network, and your network is not good.

If the mobile phone signal of the Unicom card used is full but the network is not good, check it in the following way:

1.First, check the customer service of the mobile phone terminal commitment manufacturer, and inquire whether the mobile phone supports China Unicom 4G or 5G network signal (you can call the customer service operator of the mobile phone manufacturer for inquiry).

2.Check to see if other Unicom users around you are in the same situation3Change the machine and change the card.

4.Call the local customer service to inquire if there is a network signal problem in the local area5Call the customer service of the place where the number belongs to inquire about the status of the network signal function of the number.

The mobile phone signal is full, but I can't connect to the Internet, what's going on? Let's come in and take a look.

The signal will be affected by various factors such as topography, landform, tall buildings, etc., and if you are in a relatively closed place, the signal will be affected. Here's how to deal with it:

1. Turn the phone on and off again;

2. Swap the SIM card to a family member's or friend's phone and try again;

3. Check whether other Unicom users around you can use it normally.

If you are using a Huawei phone and the " " symbol appears on the signal bar of the phone's status bar, we recommend that you take the following methods to try to solve the problem:

1.Avoid using magnetic metal cases, magnetic stands, or magnetic chucks.

If your phone uses a metal case, magnetic case, magnetic bracket or magnetic chuck, it is recommended that you remove it and try it, as metal and magnetic materials can easily interfere with the signal and cause no signal on your phone.

2.Please rule out network causes.

1. Try changing your current location.

In some more enclosed indoor environments, such as houses with dense spacing between buildings, the cell phone signal may be blocked, resulting in no signal.

The degree of network coverage of carriers varies according to different regions, and some areas may have insufficient coverage capacity, resulting in no mobile phone signal.

If your mobile phone has no signal in a specific area, or if a nearby friend's mobile phone with the same carrier** card also has no signal, it may be caused by poor network quality in your location, and it can be restored to normal after changing to another place.

2) Please try resetting the APN

Incorrect APN settings will affect the normal use of the network.

Method 1: aClick Settings;

c.Click on the APN name (APN) to go to the APN page.

d.Turn on the three-dot button or four-dot button in the upper right corner;

e.Click Reset to default.

Method 2: If your phone is EMUI and above, or HarmonyOS and above, you can also follow these steps:

a.Click Settings;

b.Tap Mobile network, then tap Mobile data;

c.Click on the APN name (APN) on the Mobile Data page to go to the APN page.

d.Turn on the three-dot button or four-dot button in the upper right corner;

e.Click Reset to default.

Settings > Wireless & Networks > Mobile Networks > Access Point Name (APN) > turn on the three dot buttons in the upper right corner > reset to default.

3) Please try to reset the network settings.

On the Reset Network Settings page, click Reset Network Settings (for dual-SIM phones, select the ** card you want to restore), and enter the lock screen password according to the on-screen prompts.

Click Reset Network Settings, and a message will be displayed at the bottom of the screen that the network settings have been restored.

3.Please troubleshoot the SIM card.

It is recommended that you install the SIM card of the same operator into your mobile phone to check, if the signal display is normal, it may be that there is a problem with your mobile phone card, it is recommended that you go to the operator's business office to replace the new mobile phone card.

4.Please try after updating your phone system to the latest version.

If the above troubleshooting does not resolve your issue, we recommend that you contact Huawei Consumer Service** (950800) for further assistance, or back up your data in advance (WeChat QQ and other apps need to be backed up separately), and bring your purchase voucher to a Huawei customer service center near you.

It's your phone card that has been dismissed. This problem will occur, and it is recommended to go to the business hall to make up for one.

The network connection does not pass, and the network fails.

You can turn off the phone and restart it, which will generally solve this problem well.

If your mobile phone cannot access the Internet normally, please check the following conditions:

1. If you don't restart your phone after upgrading to 4G**, you won't be able to use the Internet function normally;

2. Confirm whether there is a network, it is recommended that you can use it in a place with a strong signal;

3. Check whether there is still a phone bill in the account, if the balance is insufficient, you need to recharge before you can use it;

4. After 3-5 minutes of power off, restart the phone and try again;

5. Check whether the USIM card is inserted, if it has been inserted but still cannot be used, it is recommended that you go to the business hall to check whether the USIM card is faulty, or replace the card for testing;

6. If the traffic usage reaches the maximum value in the current month, the network will be automatically closed, it is recommended that you pay attention to our SMS reminder or inquire about the **product description.

I just encountered this problem for several reasons, you try them one by one:

One is that you are down, and you check the phone bill.

The second is that the network you are in now is unstable, look at the people around you.

The third is that your card is in poor contact, you need to take it down and wipe it back in if it still doesn't work, hi me.

Your card is not in good contact, you need to take it down and wipe it back in, or the network is unstable, to see if the mobile phones of the people around you can surf the Internet normally.

If you are using a Huawei phone and the mobile phone is slow to use mobile data, please take the following steps to troubleshoot:

1.Make sure you are using a VPN to access the Internet.

If your phone status bar has an icon in the shape of a key. It may be that you are unable to access the Internet or slow to access the Internet due to the fact that you have used a VPN to surf the Internet. We recommend that you open Settings, enter VPN in the search bar at the top, click to jump to the settings page, and choose to disconnect the VPN network or turn off the VPN software according to the actual situation, and try again.

2.Please confirm whether you are using an IoT card The data card is slow to surf the Internet.

Due to the difference in contract information, some IoT card traffic cards will have slow Internet access, please replace the ordinary card and try again.

3.Check whether the supplementary card is in arrears or invalid.

When the supplementary card is an arrears card or an invalid card, the supplementary card will frequently preempt the resources of the main card, resulting in slow Internet access of the main card, you can pull out the supplementary card or close the supplementary card: open the mobile phone settings, enter SIM card management or dual SIM management in the search bar at the top, click to enter the settings interface, and directly close the supplementary card.

4.Individual apps or individual** slow internet access.

If the third-party server is abnormal, it is recommended that you change the same type of application or try, or give feedback to the third-party customer service.

5.Confirm that you are using a magnetic case, metal case, magnetic stand, or magnetic chuck.

Metal and magnetic materials can easily interfere with the signal, causing the mobile phone signal to deteriorate and affect the Internet speed. It is recommended that you try it after removing it.

6.Please try changing your current location.

It is recommended that you compare the mobile phones that use the same operator's SIM card nearby, if this phenomenon occurs, it may be that the network quality in your location is poor and the Internet access is slow, and it can be restored to normal after changing to other places.

7.Make sure that the data exceeds the carrier card** limit.

Some carriers' unlimited data** has a traffic limit, and after the data usage exceeds the upper limit, the Internet speed will be reduced, you can contact the operator's customer service to confirm whether the mobile phone card** exceeds the traffic limit.

8.Turn off Power Saver (or Low Power Mode).

It is recommended that you turn off the power saving mode (or low power mode) (set > battery > power saving mode Super power saving low power mode) and keep the battery full (more than 20%).

Power saving mode (or low power mode) and low battery conditions reduce the phone's performance to save power.

9.Please reset the APN attempt.

It is recommended that you open the settings, enter APN in the search bar at the top, click the access point name (APN) to jump to the mobile data settings interface, click the access point name (APN) again, and then click the three dots in the upper right corner, and select Reset to default settings to try.

10.Please try to reset the network settings.

If the problem persists, back up your data (third-party apps such as QQ and WeChat must be backed up separately) and bring your purchase voucher to a nearby Huawei Customer Service Center for testing.

Repair spare parts** inquiry.

Boarding service. Make an appointment for service.

1. Mobile phone chip performance.

The mobile phone has a good quality of receiving signals in order to achieve the effect of good network speed and sufficient signal, and the reception of the signal depends on a special chip in the mobile phone, that is, the modem (modem). The baseband chip of the mobile phone is used to encode and decode the signal when receiving and sending the signal, in layman's terms, the baseband chip is a translation, and the speed of our mobile phone receiving and sending information also depends on the efficiency of this "translation". So if your phone's modem is poor, it will naturally affect your phone's signal.

2. The performance of the mobile phone itself deteriorates.

Many people may feel that the Internet speed has slowed down after using their mobile phones for a long time, which is actually the comprehensive performance of the mobile phone itself has deteriorated, so that the user experience is poor, which affects the Internet speed.

For example, some mobile phones will have the situation of self-starting, which takes up a lot of memory, which also affects the running speed of the mobile phone. There are also apps that we thought were closed, but they are still running in the background.

3. Operator issues.

In our daily life, there may be some places where the mobile phone signal is good, but in another place, there will be a problem that the mobile phone signal is sometimes absent or completely absent, which is not necessarily the problem with the mobile phone. The structure of the building is so complex that many corners and the like are areas where the signal is severely blocked. If the operator does not carry out special signal coverage indoors, then these problems will definitely occur in mobile phone signals, and of course, there will also be signal problems in some mountainous areas, that is, the signal coverage is not comprehensive.

4. Base station congestion.

We can definitely see that there are many places with base stations, and in different places, each operator has built its own base station, and our mobile phones get network signals by connecting to the base station. However, there is a capacity limit for base stations, and if a place is densely populated, it is normal for the network speed perception to be poor.

At present, the network signal is weak, the mobile phone memory is insufficient, resulting in the operation of Caton, the background is running multiple applications at the same time, the mobile phone is originally two or three years of the ** period, after the general is more cardy, and then overused, there will be garbled characters, weak signal, slow operation.

Sometimes although we have a signal on our mobile phone, the network will be very poor when we are talking, which may have a certain relationship with the strength of his signal. Because of the mobile communication base station we use, sometimes it has signal dead ends.

I came to this question, the phone has a signal, the network is very poor, what's going on? I think the mobile phone has a signal, the network is very poor, sometimes there is no signal in the place, or China Unicom or China Mobile Telecom, their signal is not the same.

It says it's connected to wifi, but it doesn't work, what's going on?

When the network coverage is not good, it is generally located in mountainous areas, basements, elevators, and when there is shielding or signal interference, there will be no signal or very weak. In the process of debugging, optimization and maintenance of the sedan mountain, the network may also cause the instability of the signal key sail file and the messy manuscript.

Problems with the phone itself. There may be problems with the mobile phone receiving the differential beam and SIM card slot. You need to go to the maintenance point to see it. Of course, Qingzao cannot rule out the factor of SIM card damage.
