Why cell phone signal is sometimes particularly poor

If the signal is unstable or bad on the phone, if it is a Samsung phone, it is recommended to perform the following steps to troubleshoot and deal with it:

1.It may be that the signal coverage of your location is poor, and it is recommended that you restart your phone or try it in a different location.

3.If it doesn't work, please turn it off, take out the SIM card, and try to reinsert it.

4.Replace it with a different SIM card.

If the problem still exists after the above operation, it is recommended that you bring the purchase invoice, three-guarantee voucher and mobile phone to the local service center for testing by the engineer.

The absence of a signal or a poor signal may be due to the presence of other objective conditions. Because the signal will be affected by various factors such as terrain, landform, and high-rise buildings in the process of propagation, if your location is a relatively closed place, the signal will be affected. Here's how to deal with it:

Turn the phone back on and off and try again;

Swap the SIM card to a family member's or friend's phone and try again;

See if the signals of other users around you are normal. If it still cannot be used normally after self-service troubleshooting, it is recommended that you contact the local operator's customer service for verification and handling. Use star cards to enjoy traffic multiplication; The more the traffic is used, the more you swipe the **, play the whole network, easier and more free, you can log in to the Guangxi Telecom online business hall to view.

1. There is no signal or the signal is relatively poor, mainly because the signal will be affected by various factors such as terrain, landform, and high-rise buildings in the process of propagation, such as the current location is in a relatively closed place, and the signal may be affected.

2. If the mobile phone signal of other China Unicom users is normal, the following methods can be used to troubleshoot:

Method 1] Turn on airplane mode, then turn off or restart your phone and try again.

Method 2] Test of changing the phone card to change the mobile phone card to the mobile phone of a family member or friend and try again.

Feedback, we will check and deal with it as soon as possible.

There are shelters and high building density.

Call quality is most closely related to the call environment in the first place. In complex buildings, corridors, basements, etc., these locations are often in areas where communication signals are heavily obstructed.

At the same time, the density of nearby buildings and floors will also affect the transmission of signals, and the closer the building layout, the worse the signal reception may be.

TV signal leaks.

Some experts say that sometimes, if the quality of mobile phone calls in the area where the user's small regret is located is very poor, it may be related to the leakage of cable TV signals.

If users often find that the mobile phone signal is not good, the call quality is not good, and the TV picture is often shaky, it may be caused by the leakage of the cable TV signal, and the situation should be reported to the relevant operator in time.

Privately installed wireless signal amplifier.

If you encounter a full mobile phone signal, but you can't dial **, then it is likely that there are residents around the installation of wireless signal amplifiers.

Once the number of users installing amplifiers increases, they will interfere with each other, resulting in a full signal but not playing**.

**Large and base station Bi Hall switching.

The saturation of call volume on the carrier's network can also cause a poor cell phone signal. Due to the capacity limitation of each base station, **dense places sometimes have poor network speed perception during swimming.

Some users in high-rise buildings encounter poor mobile phone signal, which may be because the location happens to receive signals from several nearby base stations at the same time, and the mobile phone will frequently switch signals between several base stations, resulting in intermittent phenomena.

Weather factors. In rainy, foggy, and snowy days, the density of water in the air will increase, and the penetration of the mobile phone signal will be weakened, and the propagation speed will naturally slow down, and the mobile phone signal will naturally become poorer.

In summer, the rain and humidity combined with the high temperature evaporation make the air more moisture, which affects the transmission of mobile phone signals. When the weather is bad, the Internet speed of the mobile phone slows down for the same reason.

The other party sets Do Not Disturb.

Finally, I would like to remind you that a setting in your phone may give the other party who calls you the "illusion" of poor call signal.

1. Poor mobile phone signal, first consider that it is caused by building blocking, move the mobile phone to a more open area, and the signal will become better.

2. If the signal does not change when moving the mobile phone, click to turn on the Flyer Pittan travel mode, and then turn off the airplane mode, and the signal will return to normal after reconnecting to the Internet.

3. If the signal is still very poor, click on the cellular mobile network in the settings.

4. Tap on the Cellular Data option.

5. Click to enable the 4G option.

6. In the Enable 4G window, select the Close option and find that the signal returns to normal.
