When will the signal difference be solved, and what is the cause of the signal difference?

If you have an unstable or bad signal on your phone, it is recommended that you:

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 persists after the above operations, it is recommended that you bring the purchase invoice, three-guarantee voucher and mobile phone to the local Samsung service center for testing by the engineer.

If the signal of the mobile phone is unstable or the signal is not good, it is generally recommended to perform the following steps to troubleshoot and deal with it:

1.It may be that the signal coverage of your location is not good, it is recommended to restart your phone or try it in a different location.

2.Connect your phone to a wireless network to update your device to the latest version.

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 signal will be affected by various factors such as topography, landform, tall buildings, etc., and if you are in a relatively closed place, the signal will be affected. Here's how to deal with it:

1. Turn the phone on and off again;

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

3. Check whether other Unicom users around you can use it normally.

If you are using a Huawei phone and the number of signal bars in the status bar of your phone is high or low, we recommend that you take the following steps to solve the problem:

1.Avoid using magnetic metal cases, magnetic stands, or magnetic chucks.

Metals and magnetic materials can easily interfere with the signal, resulting in poor mobile phone signals.

2.Please try to change to another SIM card.

It is recommended that you install other mobile phone cards into your mobile phone to view, if the signal display of other mobile phone cards is normal, it may be that there is a problem with your mobile phone card, it is recommended that you go to the operator's business office to replace a new mobile phone card.

3.Please try moving to 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. You can get outside to see if your phone signal is back to normal.

2) The degree of network coverage of operators varies according to different regions, and urban areas basically meet the coverage, but some remote areas may have insufficient coverage capacity, which will lead to poor mobile phone signal.

You can determine whether the poor mobile phone signal is caused by the current regional network coverage by whether the mobile phone signal is poor when you are only in the same area, or whether the mobile phone with the same carrier** card in the vicinity also has poor signal.

4.Check that the APN settings are correct.

Incorrect APN settings will affect the normal use of the network.

Method 1: aClick Settings;

c.Click on the APN name (APN) to go to the APN page.

d.Turn on the three dots button in the upper right corner;

e.Click Reset to default.

Method 2: If your phone is EMUI and above or Magic UI and above, or HarmonyOS and above, you can also follow the steps below:

a.Click Settings;

b.Tap Mobile network, then tap Mobile data;

c.Click on the APN name (APN) on the Mobile Data page to go to the APN page.

d.Turn on the three dots button in the upper right corner;

e.Click Reset to default.

Settings > Wireless & Networks > Mobile Networks > Access Point Name (APN) > turn on the three dot buttons in the upper right corner > reset to default.

5.Please try to reset the network settings.

If the above troubleshooting does not resolve your issue, we recommend that you contact Huawei Consumer Service** (950800) for further assistance, or back up your data in advance (WeChat QQ and other apps need to be backed up separately), and bring your purchase voucher to a Huawei customer service center near you.

First of all, people's concept of poor mobile phone signal means that when the signal grid of their mobile phone is usually only one or two, their subjective consciousness will judge it as a poor mobile phone signal or poor signal. However, this statement is unreasonable, because the number of mobile phone signal grids does not represent the mobile phone signal as a whole, let alone the standard for judging the quality of the mobile phone signal. The number of cell numbers for each user's mobile phone is not calculated by the signal strength of the uniform radio waves, but by the manufacturer of your own mobile phone.

Because it's calculated by the algorithm they use themselves. Therefore, the number of signal bars displayed by different brands of mobile phones in the same environment will be different. Therefore, the strong or poor mobile phone signal cannot be looked at the number of signal grids of the mobile phone alone.

The reasons for the poor mobile phone signal are also more varied, the first one is that the environment in which the mobile phone is located is not good, and the mobile phone signal cannot be received. The strength of the mobile phone signal is related to the environment in which the mobile phone is located, as we all know, in some places with strong shading, it is difficult to receive the mobile phone signal, such as the basement or the elevator, and the mobile phone will be automatically cut off because there is no signal. In addition to shading issues, the density of buildings can also affect the strength of mobile phone signals, and the more complex the layout of the building, the more difficult it is to receive the signal.

In addition to environmental problems, the hardware of the mobile phone itself can also cause poor mobile phone signal. The SIM card inside the mobile phone is an important carrier of our mobile phone signal reception, and if the card is often pulled and replaced after a long period of use, it will definitely cause wear and tear, and it may make the SIM card unable to be recognized and read, resulting in poor signal. In addition, there is also the problem of poor signal transmission caused by the mobile phone's own receiving base station.

As we all know, the signal of the mobile phone is received by the base station, and if there is a problem with the base station or something, the signal transmitted is not strong, and the mobile phone signal will become very poor. Moreover, the strength of the base station signal depends on which operator built it, and the mobile signal will be relatively stronger than the Unicom signal, because the mobile signal covers a wide range and the signal receiving base station construction is more, so the mobile phone signal can receive a strong mobile phone signal within the corresponding base station range.

If the amount is large, it is also one of the reasons for the poor mobile phone signal. ** When the signal emitted by the base station built by the same operator is rushed to receive by everyone, and the base station construction within the range is relatively small, it will cause the phenomenon of mobile phone signal congestion. Therefore, in places with a lot of people, such as high-speed rail stations and railway stations during the New Year's holidays, the mobile phone signal is relatively poor.

Therefore, there are many factors affecting the mobile phone signal, there are the reasons of the mobile phone itself, and there are also factors in the general environment.

As described, if it is the traffic used, it feels that the signal is not good, and it is only at night. That means that there are many people in the area, and the load of the base station is too high during the peak period of Internet access at night. For example, if there are thousands of devices within 50 meters around, this will happen.

Question: What is the reason why there is no signal on my home network around 6 p.m. every night?

Broadband or data?

Broadband, peak periods, depending on what carrier you have. It is advisable to find an operator. There is a high probability that the broadband is too poor.

Ask a question broadband. What needs to be done?

Finding the operator directly to report for repair is not your problem, and it has nothing to do with you, so you can't get it yourself. Just report for repair.

For example, telecom broadband call 10,000 for repair.

If you can't find the reason for the question, can you help?

It's impossible not to find the reason, it's nothing more than the line, the light cat. It's obviously a line light cat like this. It can only be said that the maintenance personnel don't want to engage in large-scale such on-site things, and I can't analyze it like this.

If you can't find it, you ask the operator to compensate you or refund the full amount. Change carriers. For the maintenance staff, it will help you take care of it.

Is there any other way to ask questions?

No, such an obvious odd question. The ideas are very clear, and only the operator has the authority to deal with it. Others, even if they know what the cause is, can't solve it. Because you can't touch the device.

Thank you for your question! If the maintainers can't help it, others can't do it. It's like if you have a problem with the computer, only you can touch the computer, and no matter how much others understand it, they can't touch it and can't solve it.

If I insist on the possibility, it is recommended that the light cat try it.

1. If there is no signal or the signal is relatively poor in your location, it may be due to other objective conditions. Because the signal will be affected by various factors such as topography, landform, and tall buildings during propagation, if you are in 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;

Check whether the signals of other Unicom users around you are normal.

2. If it still cannot be used normally after self-service troubleshooting, it is recommended that you contact the local manual customer service for verification and processing.

The first signal difference may be your area, which has a bad signal, so it will cause the signal to be a little worse. The second reason could be that there is something wrong with your device that will cause a bad signal.

The strength of the mobile phone signal is related to the environment in which the mobile phone is located, and as we all know, it is difficult to receive the mobile phone signal in some places with strong shading.

The reasons for the poor mobile phone signal are also more varied, the first one is that the mobile phone is in a bad environment, and the mobile phone signal cannot be received.

There are many reasons for poor mobile phone signal, such as being far away from the base station, or being subject to some interference, etc.

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.

If the signal is poor, sometimes it may be a problem with the base station, sometimes it may be a problem with the environment, and in some remote mountainous areas, the signal may be poor.

The signal difference is related to the choice of mobile phone operators and the distribution of base stations, and the base stations in too remote places are basically not controlled, which will cause the cause of signal poorness.

Unicom's signal is relatively poor, if you want a better signal, you can change the network to Telecom.

The signal depends on where you are, maybe the Unicom signal in that place is not as strong as others, or it may be that there are too many people in Unicom signal.

It may be the reason for the weak coverage of the base station, the signal coverage of each base station is limited, but the cost of building a new base station is too high.

Why is the mobile phone wifi signal poor, it may have been arranged from the factory, hurry up to test and take a look.

The 5G Unicom network is not good, and it is still unstable.

The sudden poor mobile phone signal may be due to these reasons, electromagnetic interference, regional disconnection, weather conditions, **large, base station switching.

1. Electromagnetic interference.

Mobile phone signals are transmitted through electromagnetic waves, and 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. Since each base station has capacity limitations, dense places sometimes have poor speed perception.

1. The base station is not dense, or there is no network communication facilities temporarily, resulting in weak or unreachable signals, call interruptions, etc., which generally occur in suburbs, mountainous areas and other places, which belong to signal blind spots. In this case, you can only talk when you get out of the area where the signal is weak or there is no signal.

2. When talking at the top level, I feel that the signal is very poor, in fact, the high-level is not no signal, but because the high-level can receive the signal from multiple nearby base stations, and the mobile phone will frequently switch between these base stations, and the signal is not good.

3. The signal is interfered with because some pseudo base stations, antennas, and battery waves will interfere with the signal of the mobile phone, resulting in a bad mobile phone signal.
