Why is it that sometimes the 4G signal of the mobile phone is obviously full, but it is a card?

Think about the situations you often encounter when using your phone. It's clear that the 4G signal is full, but the network speed is slower than that of a snail, especially when there are many people. In fact, the main reason for this is network congestion or network failures.

First of all, the first point is that although we can see that the 4G signal is sometimes full of cellular, we can unexpectedly face the WiFi. Therefore, the network we are actually using at this point is a broadband networkSo when there is a problem with the broadband network or router, there will be a phenomenon of slow network speed, which is often mistaken for a slow 4G network, however, there are a few cases during this period.

Second, the current 4G signal is provided by the 4G base stations of major operators. Once these 4G base stations or communication transmission networks fail, there may be a problem that the 4G signal is full but cannot access the Internet or the Internet access speed is slow. However, in general, the failure of this base station can also occur suddenly.

For example, if the network can be used normally before it is connected to the Internet, but one day it suddenly becomes unavailable, which means that there may be some problems with the base station. In this case, we can feed the situation back directly to the relevant operator. After receiving feedback, operators often send relevant technicians to repair the base station and solve the problem.

Thirdly, this is why 4G networks create traffic congestion. This is because although 4G base stations can provide relevant network services for accessory users, we need to know that each base station has capacity limitations, so once the same base station has too many users to access the network, it will cause network congestionThe introduction of users will start to slow down the network and even lose access to the Internet. This usually happens in some densely populated places, as well as in the middle of the day or at night.

Of course, this problem needs to be improved by operators through technical means.

Why is the wifi still stuck when it is full sometimes? After reading it, I finally understood!

The mobile phone is online, the mobile phone network is slow, and the Huawei mobile phone signal is full, but the 4G network is very stuck, and you can restore the network speed by learning three tricks.

The reasons for this may have a lot to do with specific signals on the ground.

Maybe it's a small problem with the network connection.,And the Android phone is already stuck.。

Me too, it was fine a few days ago, a wave of mobile phone updates, and now the signal shows 4G, or a card.

It may be because the network coverage in that place is not very good.

Because it is possible that your signal is limited and blocked to a certain extent.

If you are using a Huawei phone and the mobile phone is slow to use mobile data, please take the following steps to troubleshoot:

1.Make sure you are using a VPN to access the Internet.

If your phone status bar has an icon in the shape of a key. It may be that you are unable to access the Internet or slow to access the Internet due to the fact that you have used a VPN to surf the Internet. We recommend that you open Settings, enter VPN in the search bar at the top, click to jump to the settings page, and choose to disconnect the VPN network or turn off the VPN software according to the actual situation, and try again.

2.Please confirm whether you are using an IoT card The data card is slow to surf the Internet.

Due to the difference in contract information, some IoT card traffic cards will have slow Internet access, please replace the ordinary card and try again.

3.Check whether the supplementary card is in arrears or invalid.

When the supplementary card is an arrears card or an invalid card, the supplementary card will frequently preempt the resources of the main card, resulting in slow Internet access of the main card, you can pull out the supplementary card or close the supplementary card: open the mobile phone settings, enter SIM card management or dual SIM management in the search bar at the top, click to enter the settings interface, and directly close the supplementary card.

4.Individual apps or individual** slow internet access.

If the third-party server is abnormal, it is recommended that you change the same type of application or try, or give feedback to the third-party customer service.

5.Confirm that you are using a magnetic case, metal case, magnetic stand, or magnetic chuck.

Metal and magnetic materials can easily interfere with the signal, causing the mobile phone signal to deteriorate and affect the Internet speed. It is recommended that you try it after removing it.

6.Please try changing your current location.

It is recommended that you compare the mobile phones that use the same operator's SIM card nearby, if this phenomenon occurs, it may be that the network quality in your location is poor and the Internet access is slow, and it can be restored to normal after changing to other places.

7.Make sure that the data exceeds the carrier card** limit.

Some carriers' unlimited data** has a traffic limit, and after the data usage exceeds the upper limit, the Internet speed will be reduced, you can contact the operator's customer service to confirm whether the mobile phone card** exceeds the traffic limit.

8.Turn off Power Saver (or Low Power Mode).

It is recommended that you turn off the power saving mode (or low power mode) (set > battery > power saving mode Super power saving low power mode) and keep the battery full (more than 20%).

Power saving mode (or low power mode) and low battery conditions reduce the phone's performance to save power.

9.Please reset the APN attempt.

It is recommended that you open the settings, enter APN in the search bar at the top, click the access point name (APN) to jump to the mobile data settings interface, click the access point name (APN) again, and then click the three dots in the upper right corner, and select Reset to default settings to try.

10.Please try to reset the network settings.

If the problem persists, back up your data (third-party apps such as QQ and WeChat must be backed up separately) and bring your purchase voucher to a nearby Huawei Customer Service Center for testing.

The mobile phone signal is full, but the reason for the card is that it is very stuck when you go online, or it is also stuck when you are not on the Internet for other APP operations. If it is the first case, then the reason may be a slow network speed, such as logging in at the same time and the same wifi hotspot. Too much equipment is divided.

The network bandwidth will make the network speed slow and stuck. If it is the second case, then it is often because the mobile phone is too old, and the hardware of the device can no longer meet the functional needs of the current APP, and it seems very stupid.

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:

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

2) Swap phone and card test, that is, change the mobile phone card to the mobile phone of a family member or friend and try again.

3. There are general problems with the mobile phone signal of other users, and there may be problems with the base station near the location, and feedback can be given.

Problems with G base stations.

It may be caused by problems with the 4G network base station, or the geographical location, far away from the location of the 4G base station of the mobile phone network, and poor signal reception.

G network congestion.

Sometimes in densely populated places, there will also be a full mobile phone signal, but the network speed is very slow, because at this time, the base station access to more users, disperse the 4G signal, which will lead to the decline of the mobile phone network speed.

3. Problems with the baseband of mobile phones.

If the mobile phone network is set up normally, but the network speed is still very slow, then it may also be a problem with the hardware of the mobile phone itself, and the mobile phone baseband will also affect the signal of the mobile phone, because the signal difference between the iphone and the Android mobile phone is the most obvious proof.

It may be caused by the large number of users using 4G in the current range, which can be solved by the following methods:

1.It is recommended that you restart your phone under the test.

The network model is also affected by the surrounding environment, so it is recommended that you change to a more open place for testing.

If you have a signal coverage problem, you can report this problem to the operator staff.

The mobile phone card is a 4G network, the mobile phone signal is full to show that 2G is not a mobile phone or the old brand before, and there may be a signal problem, my mobile phone has also appeared 4G card, there is a two-G signal, and then it will be good after it is turned off again, and the 4G network system is under maintenance.

Summary. Hello dear! If the 2G network is displayed, it means that the current area where you are is not covered by the 4G signal or the mobile phone will automatically turn off the 4G function due to arrears or insufficient traffic, so it will be like this, first confirm whether the 4G switch is turned on, you can turn it on in Settings - Mobile Network - Mobile Data; If you just come out of a parking lot or elevator with no signal coverage, and your phone shows 2G, then you only need to turn on the airplane mode, wait for more than ten seconds, and then turn off the airplane mode; Or turn Settings - Mobile Data off.

Turn it off for about 1 minute, then turn it back on, and the phone can search for the 4G network normally; If the previous display is 4G, now suddenly display2G means that there may be a problem with the operator base station near you, you can call customer service** for complaint feedback, if the above methods can not be solved, you can insert the mobile phone card into someone else's mobile phone to try, if someone else's also shows 2G, it means that there is a problem with the mobile phone card, you can bring your ID card to the business hall to change the card, otherwise, there is a problem with the mobile phone, I hope it can help you!

Not good yet? Hello dear! When the 4G mobile phone signal is good, the network display is 2G, then there is only one case.

That is, the 4G signal in your area is blocked. For example, when taking the elevator, although our mobile phone signal is slow, it is scattered and patted to show that it is a 2G network. Hope it helps!

But the potato is in the same place my mobile phone has a signal, and the Kai is not in the elevator, and the card in the mobile phone without the signal is taken off and replaced in my mobile phone to have a signal.

Hello dear! If the 2G network is displayed, it means that the current area where you are is not covered by the 4G signal or the mobile phone will automatically turn off the 4G function due to arrears or insufficient traffic, so it will be like this, first confirm whether the 4G switch is turned on, you can turn it on in Settings - Mobile Network - Mobile Data; If you just come out of a parking lot or elevator with no signal coverage, and your phone shows 2G, then you only need to turn on the airplane mode, wait for more than ten seconds, and then turn off the airplane mode; Or turn Settings - Mobile Data off. Turn it off for about 1 minute, and then turn it back on, and Henghuaiyan's mobile phone can search for the 4G network normally; If the previous display is 4G, now suddenly display2G means that there may be a problem with your nearby Yunming regret business base station, you can call customer service** for complaint feedback, if the above methods can not be solved, you can insert the mobile phone card into someone else's mobile phone to try, if someone else's also shows 2G, it means that there is a problem with the mobile phone card, you can bring your ID card to the business hall to change the card, otherwise, there is a problem with the mobile phone, I hope it can help you!

Presumably many friends have encountered this situation, the reconnection of the network card when playing games, but the mobile phone signal is obviously full. In fact, the mobile phone signal ratio does not represent the network speed, today I will give you an analysis of the reasons and solutions.

1.Base station issues.

There are two types of base station problems, the first is that too many people in your vicinity are using the mobile network, so the base station load is too high. Second, you have migrated from one base station to another, but your phone has not yet reacted, so you are stuck in the network. Solution: Turn on airplane mode or restart your phone.

2.The APN has been modified

Some of you may have listened to some ways to improve your internet speed and then modified the APN (Network Access Point) of your mobile phone. In fact, if you modify the APN of the mobile phone, the network speed may be improved at that time, but there are too many sequelae, such as the current situation is one of the sequelae. Workaround:

Reset the APN of the phone to the default settings (you can send me a private message if you don't set it).

3.Power saving mode is turned on.

Sometimes in order to save power, we will turn on the power saving mode that comes with the mobile phone. In fact, this mode is to turn off, some functions of the mobile phone system to achieve the effect of power saving, so it may affect the speed of the mobile phone. Solution: Exit your phone's battery saving mode.

4.Dual SIM 4G is enabled

Nowadays, many friends have two or more mobile phone cards because of work or other needs, and today's mobile phones generally support dual SIM dual standby. However, if you enable the dual SIM 4G function, it may affect the network speed of the mobile phone, because the main card and the supplementary card will interact with the network signal from time to time. Workaround:

Disable the dual SIM 4G function.

Situation 2] If the SIM card is damaged or there is a problem with the mobile phone, you can change the phone to test whether it is the SIM card or the mobile phone is faulty.

Situation 3] The current location is a signal blind zone or suddenly no signal, you can change places to test and pay attention to whether the mobile phone signal of other users around you is normal.

Situation 4] If the mobile phone card is in arrears or is shut down, you can pay off the arrears and turn it on.

Situation 5] The service is suspended due to abnormal use of the number, such as the number being used for illegal or illegal activities.

Situation 6] Roaming in Taiwan, Hong Kong, Macao or abroad can only be used after enabling Taiwan, Hong Kong and Macao roaming and international roaming.

Situation 7] If the total traffic generated by the Internet reaches the ** traffic cap value in the current month, the system will automatically turn off the Internet access function, or limit the speed of the network, and the network will be automatically restored in the next month, which shall be subject to your ** traffic cap rules.
