As soon as I enter the house, there is no signal on the mobile phone? Who has a solution

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.

If your phone doesn't have a signal or an emergency call prompt appears on the screen, your Samsung phone recommends the following steps:

2.If it is a dual-SIM phone, please check whether the SIM card is activated: Settings - SIM Manager - SIM1 SIM2 - Click the SIM card icon - slide to turn on (the operation mode may be slightly different for different models of mobile phones).

3.If there is still no signal, it is recommended to turn off the SIM card and remove it, wipe the SIM card chip with an eraser, and then reinstall it.

4.If it doesn't work, try to change to another location to rule out whether it is caused by poor signal coverage in your location.

5.Try to change the network mode to 3G or 2G (do not select the auto-connect mode). Note: Some machines do not support changing the network mode.

6.Try to change another SIM card.

7.Update your phone's system version: Settings - About Phone (About Device) - Manual Update Automatic Update (Software Update System Update - Update). Note: Please back up the data (contacts, messages, **, etc.) in your device before upgrading.

If there is still no signal or emergency call is displayed after the above operations, please bring the purchase invoice, warranty card and machine to the nearest service center for inspection.

As soon as the phone enters the room, there is no signal, see if other people's phones are like this, if not, it is the reason for the phone.

The stability of the mobile phone signal is affected by a variety of factors, such as terrain, communication base station, atmospheric conditions and other factors may affect the signal of the mobile phone, and then affect the communication effect of the mobile phone. Everyone's geographical location is not disturbed, and the atmospheric conditions may also be different, and the degree of impact on mobile phone signals will also be different.

When we use mobile phones in our homes, dirt walls, concrete walls, and other obstacles are just some of the factors that can absorb, reflect, or interfere with the mobile phone signal, thus affecting the quality of the mobile phone signal. In addition, when we use the phone in a large indoor space, the signal quality is comparatively better, but if we use the phone in a cramped room, the signal quality may be affected more.

If you get a better cell phone signal after going out, it is usually because the surrounding environment has changed, such as being in a wide field, a high valley or other more open place, or when there are no high-rise buildings and other obstacles around.

If we were using a phone that only supports 2G networks, we could have encountered a similar situation. The signal of Qi Lisong who uses a 2G mobile phone at home may be unstable, but after going out, the signal of the 2G mobile phone will be better maintained because of the different settings of the surrounding base stations, because the transmission distance of the 2G network is relatively short.

In short, mobile phone signals are affected by a variety of factors, including geographical location, terrain, weather, obstacles, base station settings, etc., which may affect the propagation quality of the signal. Therefore, in order to maintain better signal quality, we need to choose the right phone, the right mobile phone carrier, and use the phone in the right place. <>

It may be that there are tall buildings near your home that cause signal attenuation, or it may be the reason for the reduction of the coverage of the base station near your home, and then there is an organic problem, but you can see if other mobile phones have such a situation, and you can complain about China Mobile, Unicom, and Telecom.

This condition can be due to several reasons:

1.Indoor coverage issues: Sometimes the structure of the house, isolation, metal, or other distracting factors can block the signal from entering the room, resulting in a mobile phone without a signal at home.

2.Network operator coverage issues: Different network operators have different signal coverage in different areas, and the base station near your home may have a weak signal.

3.Mobile phone problems: The phone's antenna or the part that receives the signal may be faulty, resulting in no signal at home but signal elsewhere.

If you want to improve your indoor coverage, here are some things to try:

Try using Wi-Fi to communicate, make voice calls and send messages over Wi-Fi.

Consider using a signal booster (signal amplifier) to boost the mobile signal in the room.

Place your phone near a window or in a location with a good signal in your house to get a better reception.

If the problem persists, it is advisable to contact the operator of the Shifting Movement network you are using, who can provide more specific help and solutions. <>

1. See if your current location is due to the signal blind spot, which includes outside the network coverage area, such as workshops, factories, suburbs, rural areas and other places where network communication facilities have not yet been built, as well as places where urban signal mobile phones are shielded and blocked by signals cannot be covered, such as office buildings, bar rooms, elevators, underground places, buildings and other places.

Solution: Step out of a field where there may be no signal and dial ** in a wide area.

Second, if there is no problem with the location, it may be caused by interference facilities, the mobile phone receives signals through the propagation of electromagnetic waves, so the base station establishes a connection between the transmission of radio waves and the mobile phone, so as to achieve the purpose of voice call. Interference from electromagnetic waves can affect mobile phone signals, which usually occurs in the test room.

Solution: Find the surrounding signal interference equipment, turn it off or remove it.

The mobile phone has no signal at home, and there is a signal when it goes out.

Hope it helps.

First of all, you need to know that the quality of the wireless communication signal is two-way, the quality of the mobile phone signal and the strength of the mobile base station signal will be affected, and the building is still very big on the mobile phone signal.

Two possibilities: 1: The communication base station of mobile communication does not have good coverage. --It is impossible to ask the operator to improve immediately, and it needs to be summed up and proposed.

2: Do other people's mobile phones behave like this? --If not, it means that there is something wrong with your phone, the acceptance sensitivity is not enough, or the antenna effect is very poor.

If the signal is not good, call the mobile ** and ask them to install a signal tower in your house.
