No mobile phone signal? There is no signal for mobile phones with Internet for any reason

1.There is a signal but no network.

This situation is mainly caused by two reasons: external and internal. First of all, the external reason is that you are in an area that does not have strong network coverage, such as elevators, subways or parking lots. There is often no problem with the communication signal in these places, but the coverage of the network signal is much worse than the construction.

Therefore, this is an external reason that causes the signal to be missing the network.

The internal cause is mainly due to the antenna and baseband problems of the mobile phone. For example, we all know that the signal of Apple's mobile phone has always been bad, and the main factor is the use of Intel's baseband, and the baseband chip is mainly used to encode and decode the signal when receiving and sending signals. Therefore, the quality of the baseband and the number of antennas will affect the signal of the mobile phone.

2.There is internet but the internet is very slow or even none.

This situation is closely related to the operator, base station and mobile phone. First of all, operators provide fewer network base stations in some areas, and in many places there will be damage to the base stations themselves. Then there is the congestion of the base station during peak hours, because the number of base stations that can be connected is limited, and if the limit is exceeded, the network speed will naturally slow down.

Secondly, the comprehensive performance of the mobile phone will also decline when it is used for a long time. For example, after you use a mobile phone for a year or two, all functions will naturally slow down, and the performance will be greatly reduced. Whether the application starts or loads as smoothly as the new machine, many people will naturally think that it is a problem with the network.

If the mobile phone is in arrears, just go to the business hall to pay the phone bill.

Summary. Hello dear, happy to answer for you. There are only two situations when the phone has no signal:

1. Network problems or network inability to cover. When the network coverage is not good, it is generally located in mountainous areas, basements, elevators, and when there is shielding or signal interference, there will be no signal or very weak. In the process of debugging, optimization and maintenance, the network may also cause signal instability, and the general network will return to normal, and the mobile phone signal will return to normal.

2. Problems with the mobile phone itself. There may be a problem with the receiver and SIM card slot of the phone. You need to go to the repair point to have a look.

Of course, the factor of SIM card corruption cannot be ruled out.

Hello dear, happy to answer for you. There are only two situations when the mobile phone has no signal: 1. Network problems or network cannot be covered.

When the network coverage is not good, it is generally located in mountainous areas, basements, elevators, and when there is shielding or signal interference, there will be no signal or very weak. In the process of debugging, optimization and maintenance, the network may also cause signal instability, and the general network will return to normal, and the mobile phone signal will return to normal. 2. Problems with the mobile phone itself.

There may be a problem with the receiver and SIM card slot of the phone. You need to go to the repair point to have a look. Of course, the factor of SIM card corruption cannot be ruled out.

Judgment method 1, check whether the mobile phone card slot or SIM card is damaged: you can insert other mobile phone cards to try, and then put the SIM card of the mobile phone itself on other mobile phones to see if there is a signal, if the card slot is damaged, it is recommended to replace the card slot, if the SIM card is damaged, please go to the business hall to replace the SIM card. 2. There is no signal on the mobile phone caused by network delay

You can turn on your phone's airplane mode and turn it off after five seconds, or restart your phone. 3. If the signal in the place is not good, the signal cannot be found, so you can search in another place. 4. The receiver of the mobile phone is damaged

If there is still no signal despite the above reasons, and you suspect that the mobile phone receiver is broken, please go to the after-sales location of the mobile phone for testing and repair. When there is no signal when the mobile phone and SIM card are not damaged, it may be a problem with the mobile base station or the mobile phone system.

Hello dear, 1It may be that the network of the telecom operator is unstable, resulting in unstable signal, you can call ** to the operator's customer service to inquire about the current network situation; 2.The signal module of the mobile phone may be faulty, resulting in the inability to find the signal, you can try to restart the mobile phone; 3.

The antenna of the mobile phone may have been damaged, which may also cause the signal to be unable to be found, you can try to replace it with a new antenna; 4.If you are indoors, it may be a reflection from walls and other objects (TV, refrigerator, etc.), which causes the signal to be unstable, so you can try moving to a different position.

The reasons why the mobile phone has a signal and no network are as follows:

1. SIM card arrears.

If you find that your phone is still unable to access the Internet after turning on mobile data, you must first check the status of your phone, and if you are in arrears, you only need to pay the bill as soon as possible.

2. The base station is overloaded.

The base station is not omnipotent, and it also has its own carrying limits. When a large number of devices are connected in a short period of time, there may be congestion, resulting in the inability to access the Internet normally. This is often the case at large-scale events such as concerts.

3. The mobile network of the mobile phone is not enabled successfully.

Although the switch of mobile phone data traffic has been turned on, it is likely that the connection fails because of the busy network caused by frequent operation, you can try to switch the network data button several times, if there is still no network, it is recommended to call the customer service of major operators to inquire and solve the problem.

4. The network parameters are incorrect.

If the mobile phone cannot access the Internet normally, there may be an error in the mobile network parameters. It is recommended to send it to an after-sales service store or find a professional to reconfigure the network parameters.

5. Traffic monitoring restrictions.

Many users will use the mobile phone or some third-party software to monitor the mobile phone traffic usage, once the traffic usage limit is exceeded, the mobile phone will prompt automatic disconnection of the network, in order to achieve the purpose of saving mobile phone traffic.

6. The software networking permission is prohibited.

Dual SIM users may encounter such a situation. The ** type of the two mobile phone cards may be different, so the same application may be free of traffic when using one card, while the other card is not, and it is very easy to get confused in the process of use. <>

If your mobile phone cannot access the Internet normally, please check the following conditions:

1. After 3-5 minutes of power off, restart the phone and try again;

2. Confirm whether there is a network, it is recommended that you can use it in a place with a strong signal;

3. Check whether there is still a phone bill, if the balance is insufficient, you need to recharge before you can use it;

4. Check whether the USIM card is inserted, if it has been inserted but still cannot be used, it is recommended that you go to the business hall to check whether the USIM card is faulty, or replace the card for testing;

5. If the traffic usage reaches the maximum value in the current month, the network will be automatically closed, it is recommended that you pay attention to our SMS reminder or inquire about the **product description.

The reason may be that the phone has a sudden network failure, just follow the steps below to deal with it:

1.Enter the desktop of the mobile phone to find the entrance of the settings, and click on it to operate.

<>3.In the interface of the image below, find the airplane mode.

and click On.

4.Once turned on, after the following illustration is undertaken, turn off the option for airplane mode again.

5.At this point, the signal will be stronger than before, and the network will be faster.

6.If the above steps still don't work, then you can turn off or on or restart your phone.

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 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 you are using a Huawei phone and the number of signal bars in the status bar is sometimes high or low, or the " " symbol appears on the signal bar, we recommend that you take the following methods to try to solve the problem:

1. Whether a magnetic protective shell, metal protective shell, magnetic bracket or magnetic chuck is used.

If your phone uses a metal case, magnetic case, magnetic stand, or magnetic chuck, it is recommended that you remove it and try it, as metal and magnetic materials can easily interfere with the signal and cause the phone signal to deteriorate.

2. Change your current location.

1. In some closed indoor environments, such as houses with dense building spacing, the mobile phone signal may be blocked, resulting in poor signal. You can get outside to test 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 it is caused by network coverage problems by whether the mobile phone signal is poor when you are only in the same area or the mobile phone signal status of nearby friends using the same carrier** card.

3. Check whether the APN settings are correct.

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

2. Click the APN name to enter the APN setting interface.

3. Open the three dots in the upper right corner and click Reset to default settings.

Fourth, clean the SIM card and try to change the card cross-card.

1. Please take out the ** card to observe whether the metal surface is dirty or oxidized, and it is recommended to keep the ** card clean and try.

2. It is recommended that you change to another SIM card of the same operator, or change the SIM card to another mobile phone that supports this card. If the signal icons are all displayed as no signal, it is recommended that you go to the operator's office to check and replace the SIM card with a new one.

5. Reset network settings.

This operation will delete Wi-Fi and Bluetooth records.

If the problem persists after trying the above methods, we recommend that you back up your data in advance (WeChat and QQ must be backed up separately) and bring the relevant purchase voucher to a nearby Huawei Customer Service Center for testing.

There is no network on the mobile phone, and it is generally just that the signal does not cover that place, although the current signal coverage is quite comprehensive, there will still be some corners and corners, and there may not be a place to be covered.

Try it in a different place, maybe the signal is not good there.
