Hello, yes, Huawei Maimang 4 has a telecom version and a full Netcom version, both of which can use telecom cards and mobile cards.

Check whether the SIM card you are using is a 4G card. If not, replace it. In addition, when there is a problem with the 4G signal or the 4G network has no coverage, the phone will automatically switch to the 3G 2G signal.

1.You need to go to the business hall to change the special mobile phone card. If it is a replacement**, it will generally not take effect until the next month. On other 4G mobile phones, if you can't use 4G, you can basically confirm that it is a card problem.

2.Make sure to turn on the 4G switch on your phone. In the settings, the network mode is set to 4G 3G 2G mode.

3.Check if there is 4G signal coverage in your local area. It is recommended to try the card on another phone. If there is a problem, it is recommended to call the operator's customer service for feedback.

4.Pay attention to the case that the purchased phone supports 4G. Generally speaking, the customized version of the mobile phone only supports the 4G service of the operator, for example, the customized version of Telecom only supports the 4G network of Telecom, and the customized version of the mobile only supports the mobile 4G network.

The supplementary card of the dual-SIM mobile phone can only be used for 2G services.

5.In some areas (Shenzhen), if the 4G** traffic runs out, the 4G network will not be registered. It is recommended to turn off 4G temporarily.

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.

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.

Specific steps: 1. Settings.

4. Turn off 4G

Pull down the menu bar, turn on the 4G button, and adjust the position to the good signal**.

Conditions for the mobile phone to use the 4G network correctly:

1) Change your phone to a phone that supports 4G.

2) Replace the mobile phone card with a 4G card.

3) Mobile phone card registration 4G business.

4) Turn on 4G on your phone.

5) Turn on mobile data in your phone's settings.

6) There is relatively good 4G signal coverage.

7) The 4G standard of the mobile phone is required to be the same as the 4G network standard of the operator of the mobile phone card.

8) The 4G tariff is sufficient.

Let's rule them out one by one, first of all, whether you are using a 4G card, secondly, whether you have opened 4G traffic service with the operator, and whether the SIM card is put well, or whether the signal is good (you can change to a 4G mobile phone to try if you can access the 4G network), restart the mobile phone to try. Click "Settings > More" to see if the "Enable 4G" switch is turned on on your phone. If it still doesn't work, bring the warranty card to the after-sales service center for maintenance.

Back up your phone's data before servicing.

First see if the SIM card is a self-cut card, the cut SIM card sometimes has signal problems that lead to the inability to use 4G, it is recommended to go to the business hall to replace the standard SIM card.

There is no 4G signal or the 4G signal is very poor in some areas. When there is a problem with the 4G signal or the 4G network is not covered, the phone will automatically switch to the 3G or 2G signal.

The 4G frequency bands supported by each operator are different, China Unicom mobile phones cannot use the 4G network of China Mobile, and China Mobile cannot use the 4G network of China Unicom.

If that doesn't work, go to the nearest Huawei customer service center to back up your data. Hope that helps.

Hello, please confirm if the card is a cut card? Sometimes there will be signal problems with the SIM card cut, it is recommended to go to the business hall to replace the regular Nano card;

2. Please confirm whether the SIM card supports 4G and has opened 4G**, if not, please turn off 4G and restart the phone, because the 4G signal will affect the signal of 2 3G.

3. If you are using 4G, the 4G network is now in the early stage of network deployment, and the signal will be unstable. Please check if the signal is normal after turning off 4G and restarting your phone, 4G can be turned on when needed.
