Why does Huawei Mate suddenly have a weak signal

Naturally, I was not immune to the problem of signal loss. It seems that this problem is very common, after tossing for a while, there is no improvement after going to the business hall to change a card, the problem is still not solved, or even worse, and then I thought, will it be that the SIM is too thin? So a layer of transparent tape was glued on the back of the card, and then stuffed into the card sleeve, after testing, repeated plugging and unplugging more than ten times, there will be one or two times that the card can not be found, and there is no signal loss problem after more than ten hours of standby, and it seems that the problem has been solved.

Try it if you encounter this problem. Scotch glue should not be too thick, my one layer is fine, I have tried two layers of cards can not pop out by themselves, and it is difficult to pull out, it is best to leave some on the tape to facilitate the use of fingernails to pull out the card.

The reason for the signal loss, I speculate, is neither because of the baseband version nor because of the SIM card, but probably because of the insufficient accuracy of Huawei's card sleeve or the contacts in the card sleeve, resulting in poor contact at individual points.

I am 2014 10 19 buy Huawei Mate7, the call voice is shaky, that is, others can't call**, there is suddenly no signal when dialing, according to customer service requirements; System upgrades. Replace your card. In the end, there was still no effect, and finally the customer service could only ask me to go to the mobile phone testing center to do the test, we support domestic products, and the manufacturer should also consider our situation.

You can only use a standard micro SIM UIM card for your mobile phone, please go to the business office to replace the standard micro SIM UIM card.

The signal display of the mobile phone card is strongly related to the network environment, if you are using a Huawei mobile phone.

When the number of signal bars in the status bar of the mobile phone is large or low, it is recommended to take the following methods to try to solve the problem:

1.Make sure you are in a good network environment.

Try changing your current location.

1) In some closed indoor environments, such as houses with dense spacing between buildings, the mobile phone signal may be blocked, resulting in poor signal.

2) The network coverage of operators varies according to different regions, and some areas may have insufficient coverage capacity, resulting in poor mobile phone signals.

If your mobile phone has a poor signal in a specific area, or a nearby friend's mobile phone using the same operator** card also has a poor signal, it may be caused by the poor network quality in your location.

2.Please avoid exposure to metal or magnetic materials.

interference. If your mobile phone uses a special metal protective case, or you are in an elevator, car and other environments, it is recommended that you remove the mobile phone protective case or leave the elevator, car and other environments, metal and magnetic materials are easy to interfere with the signal, resulting in poor mobile phone signal.

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

Special configurations of some networks may cause your mobile phone signal to be poor, which can be restored after restarting your phone or turning on airplane mode.

4.Please reset the APN

Open Settings, enter APN in the search bar at the top, tap Access Point Name (APN) to jump to the mobile data settings interface, tap Access Point Name (APN) again, then tap three or four dots in the upper right corner, and select Reset to Default Settings to try.

5.Please reset your network settings.

6.Please remove the SIM card.

1) If your mobile phone card is a manually cut card, it may cause signal problems due to non-standard shape and poor contact, so it is recommended that you bring your personal ID card.

Go to the operator's business office to apply for a standard mobile phone card.

2) Dirty or oxidized mobile phone card will also lead to poor contact, it is recommended that you keep the mobile phone card clean.

7.Please update your phone system to the latest version.

If your phone still has a poor signal, please contact Huawei Consumer Service** (950800) for further assistance, or back up your data in advance (third-party apps such as QQ and Weiwu Shixin need to be backed up separately), bring your purchase voucher, and go to a Huawei customer service center near you for testing.

The solution to Huawei's poor mobile phone signal and poor network speed is as follows:

1. Reset the mobile network.

A sudden drop in cellular network may be a problem with the network connection, and you can try resetting the network. The method is also very simple, open the flight mold and wait for half a minute. Of course, if you find this method troublesome, you can also try it, and it is more troublesome to shut down and restart.

2. Set the network mode.

When choosing a network, it is recommended that you give priority to "4G network first" and then "LTE bearer system", so that the network speed will be greatly improved. The opening method is also very simple: Settings - Mobile Network - Network Type - 4G Network Priority - Modify Access Point - Bearer System - LTE, and save and close after setting.

3. Access to APN.

The methods of the three major operators to access the APN are also different, and the mobile direct input is OK; China Unicom needs to create a new APN "WONET", change the macro to 460, change the MCC to 01, and then change the APN type to "default, supl, dun". Telko: Create an APN, enter CTLTTE, username ctnet@mycdma, password, MCC 460, MCC 03 or 11, and save it.

1. If your mobile phone is wearing a metal protective case, it is recommended that you try to remove it, because the metal material is easy to interfere with the signal and cause the mobile phone signal to deteriorate. 2. If there are problems with the mobile phones using the same operator's network around, it may be that the local network is abnormal, it is recommended to check in another place, or consult the operator. 3. Please take out the ** card to observe whether the metal surface is dirty or oxidized, which may affect the reading of the signal, it is recommended to keep the ** card clean and try.

4. Turn on Airplane mode, or try to reset network settings or even restart your phone. 5. If the above methods still can't solve the problem, it is recommended to back up the mobile phone data and bring the relevant credentials to the offline service store for testing.

Hello dear.

The reasons and solutions for poor signal on Huawei phones are as follows:

1. If your mobile phone is wearing a metal protective case, it is recommended that you try to remove it, because the metal material is easy to interfere with the signal and cause the mobile phone signal to deteriorate.

2. If there are problems with the mobile phones using the same operator's network around, it may be that the local network is abnormal, it is recommended to check in another place, or consult the operator.

3. Please take out the ** card to observe whether the metal surface is dirty or oxidized, which may affect the reading of the signal, it is recommended to keep the ** card clean and try.

4. Turn on Airplane mode, or try to reset network settings or even restart your phone.

5. If the above methods still can't solve the problem, it is recommended to back up the mobile phone data and bring the relevant credentials to the offline service store for testing.

There are many factors that affect positioning and navigation, please try the following methods to check and confirm:

1.Influencing factors such as magnetism, metal phone cases, magnetic brackets, etc.

Metal or magnetic materials will interfere with and shield GPS signals and affect the reception of signals. If you're using a metal case, magnetic case, magnetic stand, or magnetic chuck, we recommend that you remove it and reposition it. For example:

If the center console of the car is interfering, it is recommended that you change the position and move your mobile phone to the window and other places to check.

2.Position simulation software impact.

The location simulation software uses a virtual location, so when it is turned on, it will affect the real positioning results, and if you do not exit the location simulation normally, it will always show that the GPS signal is weak.

3.Reasons for geographical location.

1) Towering buildings, dense buildings, roofs, and walls will affect the reception of GPS signals and lead to inaccurate positioning. We recommend that you enable Wi-Fi or move to an open area.

2) The signal is usually poor in tunnels, viaducts, mountainous areas and other heavily obstructed places or high-speed driving scenarios, and the GPS signal can be recovered when you go out of the area. If the GPS signal has been poor, it is recommended that you try restarting your phone.

4.Whether the position switch and location permission are enabled.

Please check whether the navigation software has permission to read the location information. Steps: Open the phone settings, enter permission management in the search bar to enter the permission management interface, click the app that cannot locate the navigation, and turn on the location information permission.

5.Please check if your phone settings are correct.

1) Please make sure that the mobile network connection is normal and the location information is enabled in the drop-down notification bar.

2) Please confirm that the location service settings of your phone are correct. Steps: Pull down the notification bar, press and hold the location information icon to enter the location service interface, click to improve accuracy, and enable Wi-Fi scanning to improve the accuracy of network positioning.

If the above methods still do not solve your problem, we recommend that you back up your data in advance (third-party applications such as QQ and WeChat must be backed up separately) and bring your purchase voucher to a nearby Huawei Customer Service Center for testing.
