The 4G signal is only one bar, and it often becomes an E network?

The reason why there is no signal on the mobile phone is because the signal will be affected by various factors such as terrain, landform, and tall buildings during the propagation process, 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 there is a signal from other Unicom users around;

It should be that the 4G signal is not good and the mobile phone signal falls back to the edge, the landlord can change the location to try, if there is still a problem, it is estimated that there may be 4G network failures in the entire area, you can call the operator's customer service** to reflect the situation.

If you are at home, you can install a mobile phone signal amplifier.

Antong antenna, making 300m-6G frequency antenna.

If you are using a Huawei mobile phone, there are many reasons why the mobile phone does not have a 4G signal and only a 2G signal, please follow the following methods to troubleshoot:

1.If you have no 4G signal on the primary SIM card when you are using dual SIM, make sure that the supplementary SIM card is receiving MMS.

If you encounter a problem when the supplementary card receives SMS and MMS messages, the main card will display 2G:

1) You can enter the information interface, click on three dots or four dots, enter More > Settings > Advanced or Settings > Advanced, and then set Auto MMS to Off.

2) If your mobile phone supports dual VoLTE dual pass, it is recommended that you enable the Dual SIM VoLTE function: in the VoLTE network coverage area, when the dual HD icon is displayed in the status bar of the mobile phone, two cards can work at the same time.

2.Please make sure the 4G switch is enabled.

1) When installing a single SIM: Please swipe down from the top of the phone screen, open the shortcut menu, press and hold the mobile data icon, enter the settings interface, turn on Enable 4G or select 4G 3G 2G in network mode to automatically select.

3.Please move your current location.

You can consult the network coverage of the local operator, or observe the mobile phone network conditions using the same operator's SIM card nearby, if there is no 4G network in the same situation, it is generally caused by the poor and unstable 4G network coverage of the local operator, it is recommended that you try after moving to other places.

4.Please restart your phone or switch on and off airplane mode.

The special configuration of some networks may cause your phone to be unable to return to the 4G network for a short period of time, but it can be restored after restarting the phone or turning on the airplane mode.

5.Please reset the APN

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

It is recommended that you open Settings, enter APN in the search bar at the top, click Access Point Name (APN) to jump to the mobile data settings interface, click the Access Point Name (APN) again, then click the three dots in the upper right corner, and select Reset to Default Settings.

6.Please reset your network settings.

7.Please remove the SIM card.

1) If your mobile phone card is manually cut card, it may affect the signal reading due to non-standard shape and poor contact, it is recommended that you bring your personal ID card to the operator's business office to apply for a standard mobile phone card.

2) Dirty or oxidized SIM cards will also affect the reading of signals, so it is recommended that you keep the SIM card clean.

8.It is recommended to update to the latest system version in a timely manner.

If your phone still only has a 2G signal, contact Huawei Consumer Service** (950800), back up your data in advance (third-party apps such as QQ and WeChat need to be backed up separately), and bring your purchase voucher to a nearby Huawei Customer Service Center.

According to the information you provide, if you cannot use the China Unicom 4G network, we recommend that you use the following conditions to troubleshoot the 4G network:

**4G network function has been activated;

The mobile terminal supports China Unicom 4G network;

The location has a 4G network covering China Unicom;

The number card is a USIM card.

Therefore, you can check whether you meet the above conditions, and you can use the China Unicom 4G network only after you meet them. If you are still unable to use the 4G network after troubleshooting, we recommend that you replace the card and consult your local Unicom customer service to check whether the base station facilities are faulty.

What happened to the mobile network 4G becoming e.

Our current network is mainly 4G, and everyone also believes that in this era, 4G network gives us more convenience. But many times, we always encounter network signal congestion. When there is a signal problem on our network, there will be an E on the phone.

To this"e"We all know that this means that there is a problem with the network signal, but we don't know what it means.

In fact, E is the abbreviation of Edge, and in the past, we used 2G signals. The 2G signal gives us the feeling that it is much slower than the 4G, and this E signal is actually a signal between 2G and 3G, specifically in the numbers. Although the E signal is faster than the 2G signal, this speed still cannot meet the needs of people now.

If we use it, the mobile phone signal suddenly becomes e, then this is the biggest headache for us, because the network speed is much worse. So why e-signals?

There are several reasons why an e-signal appears on mobile phones. The first one is because of a problem with the configuration of the phone. When the mobile phone is produced, its configuration is fixed, and its performance is determined by the configuration.

Some mobile phones are receiving 4G signals and are prone to problems because its performance is not strong enough. If it's because of this, the best solution is to change to a better phone.

The second reason for network coverage. Most of the people who usually use 4G LAN, this network is characterized by strong signal and fast natural speed. However, its coverage area is not large, and only some areas can receive strong signals, so out of this coverage, then the signals we receive will be very weak.

The best solution is to find a place with a strong signal to use, so that there will be no E signal.

The third network **. Although it is now the era of 4G, there are still people who use 3G network and 2G network, and we all know the speed of the latter two, which is naturally not so fast. So if you want to change the reality of the e-signal, the best thing is to change the network**.

The E signal can really feel troublesome, especially in this era of 4G networks, where the speed difference can be easily felt. If you want to really change reality, you can only let science and technology develop.

E network is 2G signal, 2G signal is almost impossible to access the Internet, this has nothing to do with the signal is not satisfied, 2G signal and 4G signal, 5 signal base station is different, if there is no 4G and 5 signal around the area, only 2G signal can be received, mobile phone damage or SIM card damage will also appear can only receive 2G signal.

Maybe it's because the 2G signal is very strong, and the other 3G4G5G signals are very poor, but it's more likely that your phone's receiving system is out of order, and you just need to restart your phone.

If there is an E network, it may be a problem of the region, and there may be a possibility that the user is operating the mobile phone, there is a spring and some mistakes, if this is the case, you can try, change the mobile phone card to a card slot, start it and try it, so if it still doesn't work, it is a problem of the region.

4G becomes E means that the network is switched from 4G to EDGE network, this network is quite popular in the past, its network speed is similar to the past 2G and 3G, generally in the middle of the two halls, almost can be counted, and the network speed is about 40KB S. At this time, it means that the user's mobile phone signal is no longer unblocked, which can be understood as reduced to 2G.

The network signal is unstable, so try it in a different place.

1. Because the 4G mobile phone can search for the 4G signal, if the mobile phone used is not a 4G mobile phone, the state of the display of the use of traffic is when the signal in the network environment is not good, there is no 4G signal, and when the E is displayed, it means that only the 2G signal is searched. 3. At present, the 4G signal in some areas has not been fully covered, and the 4G signal may not be searched when it is used, and the displayed usage traffic will also be E. If you still can't use the 4G network after exclusion, it is recommended to consult the local 10086 customer service for feedback.

If you are using a Huawei phone, you can do it by doing it here:

1.Please make sure that the SIM card is not in arrears and is stopped.

Please make sure that the mobile phone card is not in arrears and is shut down, and you can confirm it by dialing **. If your phone is in arrears, please top up your phone bill and try to connect to the Internet.

2.Please make sure that the ** card for Internet access is set correctly.

1) Swipe down from the top of your phone screen to bring up the shortcut menu and check if the mobile data icon is lit.

3.Please try it after restarting your phone.

Sometimes, temporary network failures may cause you to be unable to access the Internet through data services, turn off airplane mode, or restart your phone to see if it can be restored.

4.You can't get online while using a VPN.

If you see a key icon in your phone's status bar, you may be using a VPN. You can search for VPN in the settings, find and enter the VPN settings interface, and it is recommended to disconnect the VPN or turn off the VPN software according to the actual situation.

5.Try to change your current location.

It is recommended to compare the surrounding mobile phones with the same operator's SIM card, if this phenomenon is present, it may be that the network quality in the location is poor and the Internet cannot be accessed, and it can be restored to normal after changing to other places.

6.Some apps can't use mobile data to surf the web.

2) The wrong date may cause some applications to fail to resolve the server and use the network, it is recommended that you set the date to automatic: please open the search box at the top of the mobile phone settings and enter "date", click the date and time to enter the settings interface, and turn on the automatic setting switch.

7.5G phones can't access the Internet after turning on the 5G switch.

The 5G network is still in the early stage of construction, and there are problems with the compatibility of the 5G network in some areas, resulting in the inability to access the Internet after the mobile phone is turned on 5G, it is recommended that you temporarily turn off the 5G switch: swipe down from the top of the mobile phone screen, call out the shortcut menu bar, press and hold the mobile data icon to enter the settings interface, and turn off the 5G switch.

8.Internet access is not possible with an IoT card data card.

Due to the difference in contract information, some IoT traffic cards require a specific APN to access the Internet.

9.Internet access is not available when roaming internationally.

1) If your ** card cannot access the Internet when roaming internationally, please swipe down from the top of the mobile phone screen to call out the shortcut menu, find and hold the mobile data to enter the settings interface, and make sure the data roaming switch is turned on.

2) Please consult the customer service of the **card operator: whether the network of the operator you roam in your local area has opened the data roaming service, and whether your ** supports the use of international roaming mobile data.

10.Try resetting the APN and resetting the network settings.

If this is not the case, take the following steps to try:

1) It is recommended to 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 button in the upper right corner, and select Reset to default settings to try.

If the above troubleshooting does not resolve your issue, we recommend that you back up your data in advance (WeChat QQ and other apps need to be backed up separately) and bring the relevant purchase voucher to a nearby Huawei Customer Service Center for maintenance.

on the phoneSettingsoptionWireless and networking", ".Mobile NetworksNot enabled under SettingsMobile data”。Choosing to turn off is a way to limit the data charges charged by the operator, and the mobile phone can only use wifi to access the Internet. After turning it on, you can use the mobile phone card to access the Internet from the mobile network, but the operator will charge the data fee as agreed.

1. Check the mobile phone network signal, Android phone: open [Settings] - [About Phone]; 2. Then click [Status Information] - [SIM Card Status] - [Signal Strength], and the iOS system is: dial pad [*3001 *], click Call, the Field Test startup page will pop up, and the signal value will be displayed in the upper left corner; 3. Try airplane mode or restart, more and more caches on the phone, which will cause the phone to run slowly, and may even affect the network speed. 4. Mobile phone setting problems, Android phones:

Settings - Carrier Network - Mobile Network, iPhone: Settings - Cellular Network - Turn on Mobile Network Data, if you want to connect to 4G, you need to tap the Cellular Data option - Enable 4G;

There is a 4G signal, but, in some specific places, it can only be said that it can be opened**, but it can't meet the needs of Internet access!

Many people are puzzled by the fact that the mobile phone signal is full but always disconnected, but the reason is very simple.
