Why has the cell phone signal deteriorated since the beginning of this year?

Because 5G networks are being built now, the signal of other networks will be relatively poor.

This is because the mobile phone is about to be updated to 5G, and the signal will be bad when it is updated.

Now it has been upgraded to 5G, so the mobile phone signal has deteriorated since this year.

Because they are now upgraded to 5G, the original mobile phone 2G3G signal will become weaker.

Because the 5G network is constantly covering, and 4G mobile phones have been slowly eliminated.

The reason why the mobile phone signal has deteriorated this year is because of the new 5G network this year.

The reason for the deterioration of mobile phone signals this year is the imminent spread of 5G.

Now the data is also being updated, and the mobile phone card is also needed to improve the network at any time.

The sudden poor cell phone signal could be due to these reasonsElectromagnetic interference, regional disconnection, weather conditions, **large, base station switching.

1. Electromagnetic interference

Mobile phone signals are through electromagnetic waves.

When the interference of certain electromagnetic waves exceeds a certain level, the mobile phone will have no signal or drop call.

2. The area is disconnected

When the partners cross one service cell to another during the call, the voice channel will be switched, and if the handover fails, the call may be interrupted.

3. Weather conditions

Weather such as strong winds and thunderstorms will also affect the transmission of mobile phone signals.

4. Large, base station switching

The saturation of call volume on the carrier's network can also cause a poor cell phone signal. Due to the capacity constraints of each base station, network speeds can sometimes occur in densely populated places.

1.Please check the SIM card.

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

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

2.Please avoid interference from metal or magnetic materials.

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 rule out network causes.

1) Make sure you are in a good environment.

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

Carriers' network coverage varies depending on the region, 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 if a nearby friend's mobile phone using the same carrier** card also has a poor signal, it may be caused by the poor network quality in your location, and you can return to normal after changing to another place.

2) Please restart your phone or switch on 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.

3) 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 Dots or Four Dots in the upper right corner, and select Reset to Default Settings to try.

4) Please reset the network settings.

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

If your phone still has poor signal, contact Huawei Consumer Service** (950800) for further assistance, or back up your data in advance (third-party apps such as QQ and WeChat need to be backed up separately), bring your proof of purchase, and go to a Huawei Customer Service Center near you.
