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.

The mobile phone must support 3G or 4G network standard, and the mobile phone SIM card must be enabled to enable the relevant 3G or 4G service, and then be correctly set up to use it under the coverage of the relevant network signal, which is the premise of obtaining the corresponding service.

Mobile phone Check whether your phone supports 4G, secondly, whether the phone has enabled the priority use of 4G network, and check whether the mobile phone card is inserted in card slot 1.

Dear, glad your question, according to your description. 1 There is only a mobile 2G network nearby, no 4G and 3G networks; 2 The mobile phone only supports mobile 2G network, and does not support mobile 3G network and 4G network; 3. The signal reception function of the mobile phone is damaged, resulting in the mobile 2G network can only be used; 4. The display function of the mobile phone is abnormal, resulting in the mobile 2G network being displayed even though the mobile 4G network is used.

If you cannot use the 4G network of China Unicom, we recommend that you use the following conditions to troubleshoot the 4G network:

Use China Unicom 4G** or have opened 4G network function;

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.

A1First of all, the first step is to find another mobile phone to exchange cards for testing, if you change the normal mobile phone, there is still no 4G, then the problem is in the card. If the card of the normal mobile phone also shows 2G on your mobile phone, then the problem is on the mobile phone.

2.If the surrounding mobile phones also show a 2G network, then the 4G base station covering the area is interrupted and needs to be handled by the operator.

3.If it is a card problem, you need to go to the operator's business hall to replace the mobile phone card, and at the same time, the operator needs to check whether the 4G service is normally activated.

4.If it is a mobile phone failure, then you need to go out to repair the mobile phone to investigate, whether the functional device is faulty, or the mobile phone 4G function is not turned on.

Hope it helps.

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 to see if there is a signal from other Unicom users around.

The mobile phone card shows 2G reason:

1. The problem of mobile phone settings: because the mobile phone is set to 2G mode, the signal of the mobile phone becomes a 2G network; It is possible to change the network settings to 4G.

2. The 4G network signal problem where the mobile phone is located: The local 4G network signal is not good and the coverage is not comprehensive, resulting in the mobile phone's signal becoming a 2G network. Leave the area to see if the phone's 4G signal is restored.

3. Mobile phone SIM card failure: In this case, you need to go to the business hall in time for SIM detection, if it is a SIM card problem that needs to be replaced, to avoid affecting your own use.

4. The system of the mobile phone crashes: you can change the mobile phone or set the airplane mode, and then turn off the airplane mode after 5 seconds, and the signal can be restored.

5. Mobile phone case interference signal: whether to use metal protective shell, magnetic protective shell, magnetic bracket and other accessories, metal and magnetic materials are easy to interfere with J&'s signal reception, it is recommended to remove the accessories to view.

6. Dirt or oxidation on the metal surface of the SIM card: it will cause unstable signal reception, which can be viewed after cleaning.

Reasons for poor mobile phone signal;

1. Check the mobile phone signal;

If your phone uses a metal, magnetic case or bracket that has an impact on your phone's signal, we recommend that you remove it and try it.

If you are in an underground parking lot, elevator hall and other environments, the coverage of the mobile phone signal is susceptible to these environmental impacts, the signal will be relatively weak, and the data network will also be affected, so it is recommended to go to an open area, such as an outdoor open environment for testing.

2. Switch on and off the flight mode;

You can try to try by toggling the airplane mode and re-registering the network after trying.

3. Check whether Do Not Disturb mode is enabled. <>

Hello, there are several possible reasons for this problem:

2. Find out whether it is a problem with the mobile phone, whether the mobile phone only supports mobile 2G network, and does not support mobile 3G network and 4G network;

3. It is also possible that the receiving signal function of the mobile phone is damaged, resulting in the only mobile 2G network being used;

4. The display function of the mobile phone is abnormal, resulting in the mobile 2G network being displayed although the mobile 4G network is used.

5. The operating system of the mobile phone is unstable, which may lead to the situation that it cannot connect to the Internet or only connect to the 2G network.
