Anonymous users2024-02-07If 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.
You can check whether the above conditions are met, and you can only use the 4G network after you meet them, if you still can't use the 4G network after eliminating them, it is recommended to consult the local Unicom customer service to check whether the base station facilities are faulty.

How to modify. It's suddenly 2g.
Maybe the signal in your area is not very good.
This will cause the phone to suddenly become 2G.
Not for this reason.
Everyone else's is normal.
You can also try changing to airplane mode while looking at the Internet.
After switching back.
Tried it. Did it suddenly become normal before, right?
First, the main reason is that you look at the network settings to see if you accidentally modify the network, and second, you try to shut down and restart.
Try it. If none of the above is available, you can only restore the network settings in the settings.

Anonymous users2024-02-03A1First 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.
Ask a good question, thank you.
Give a thumbs up. Have a great day.

Anonymous users2024-02-01If 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 remove the SIM card.
If your mobile phone card is a manually cut card, it may affect the reading of the signal due to non-standard shape and poor contact, so it is recommended that you bring your personal ID card to the operator's business office to apply for a standard mobile phone card.
Dirty or oxidized SIM cards will also affect the reading of the signal, so it is recommended that you keep the SIM card clean.
3.Please make sure the 4G switch is enabled.

4.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.
5.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.
6.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.
7.Please reset your network settings.
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.
