Why is the Internet speed of 4G mobile phones slow?

1. How to check the slow speed of the connected wifi Internet access:

1. Go to Settings - Application and Permissions More Settings - Application Management - ("More" in the upper right corner and select "Show System Processes") - Find WLAN - Click Storage, select Clear Data and Cache, and then reconnect to WiFi to try (some models enter Settings - More Settings - Applications - All - Find WLAN);

2. Check or reset the settings of the wireless router, try wired broadband or replace a new wireless router (at the same time, the network speed of wifi is related to the distance from the router, the bandwidth of the broadband and the number of people connected);

3. Go to Settings - System Upgrade, some iQOO (Monster) UI versions and FunTouch models need to go to Settings - My Device - iQOO (Monster) UI version FunTouch OS version to detect and update the system;

4. Enter the mobile phone settings - system management More settings - backup and reset Restore factory settings - restore all settings to see, the operation will cause the logged third-party software to need to log in again, but will not clear the **, ** and other files in the phone storage, please confirm that it does not affect the use of some third-party software before restoring all settings. To avoid data loss caused by abnormal operation, it is recommended to back up the important data of your phone first.

2. Slow Internet access using data networks

1. Change to a location with a better network environment or enter the mobile phone settings - mobile network dual SIM and mobile network - access point - change the access point to try (avoid being in a closed room, surrounded by tall buildings, poor network signal coverage and other environments);

2. Switch to 4G network use;

4. It is recommended to change the time period and use different software to use the data network for comparative observation.

1. Caused by the instability of the resources of a single software, such as: the software server is unstable, it is recommended that you try to change the time period;

2. Consult the operator's customer service whether it is caused by excessive SIM card traffic usage, or compare the network speed with the 5G card around you;

The G network is currently in the construction stage, and operators may have certain restrictions on the speed of mobile phones registered to 5G base stations at the same time.

4. Operators may optimize and adjust 5G base stations, which may affect network stability.

5. At present, the 5G network is under construction, although the 5G signal is displayed in some areas, the network itself is not very stable, it is recommended that you change the time or environment to use.

If the above methods are not improved, you can bring your mobile phone and valid purchase voucher to the service center for testing and processing, pay attention to WeChat *** "vivo" or "vivo customer service" to inquire about the address of the service center**, it is recommended to contact before going to ensure that there is a staff reception and then go over, so as to avoid delaying the precious time to run in vain.

The slow speed of 4G Internet access is related to a variety of factors, such as: whether it is correctly connected to the 4G network, terminal settings, whether it exceeds the user-customized traffic**, network coverage, the number of users, etc., first confirm whether it can connect to the 4G network normally, and then rule out whether it exceeds the user-customized traffic**, whether it is a terminal problem. In terms of network coverage:

There may be the following reasons:

Mobile network issues.

The mobile phone shows mobile 4G only means that the mobile phone can be connected to the mobile 4G network, and the actual network speed is affected by factors such as signal strength, network conditions in the environment, and the optimization of the network signal by the mobile phone itself. If it is only an occasional drop in network speed, it is generally a normal phenomenon, and you can turn on the airplane mode and wait for a few seconds before turning it off and restarting the network. The details are as follows:

There are too many users of the G base station, and the mobile phone cannot communicate with the base station in time, or the communication is congested. Similar to using a router at home, if the router's broadband operator server connection is not normal, network congestion and other phenomena, even if you can receive a full WIFI signal normally, it is not possible to solve the problem of too many users of the 4G base station. If the location is large and there are many devices connected at the same time, network congestion will be formed, and the base station will not be able to communicate with the network server in time for the signal transmitted by our mobile phone;

2. Fast moving, for example, on the high-speed rail will also affect the signal, because the speed of the high-speed rail is fast, the average speed is also higher than that of the vehicle driving on the high-speed, so the mobile phone needs to frequently receive the signal of the switching base platform, and there may be data loss in the middle, and the signal situation of different base stations is different, which will also affect the network signal of the mobile 4G;

3. The network speed of some mobile phones will be affected by the network optimization environment in different regions, if your mobile phone often has a slow network speed or cannot find a signal, you can find the network in the mobile phone settings, restore the network settings of the mobile phone, and the mobile phone will re-set the search network, which can alleviate the poor network to a certain extent;

4. The mobile phone shows that the mobile 4G only means that the mobile phone can be connected to the mobile 4G network, and the network speed also depends on the strength of the signal, the network conditions of the environment and the optimization of the network signal by the mobile phone itself.

This is mainly due to the insufficient coverage of 4G single base stations.

On the other hand, because of the high frequency band of the 4G signal, the attenuation is faster when crossing the barrier. At present, the frequency band used by TD-LTE is basically above 2000MHz, the penetration of this frequency band is not strong, the loss is large, and there is no problem with outdoor coverage through the base station, but in dense building areas, if there is no optimization of indoor coverage, the signal in the indoor will be affected.

In addition to external reasons that make the mobile phone have no signal, the unstable power supply of the mobile phone will also cause the mobile phone to have no signal. The power supply of the receiving circuit is insufficient, the voltage is fluctuating, and the reception of the signal cannot be stabilized, so the mobile phone will not be able to access the Internet, and even cannot dial **.

How to fix the slow internet speed of your mobile phone:

1. Leave the crowded place and try again;

2. Check whether the network signal is good, poor network signal will affect the Internet speed;

3. Check what the current network is, if it is a 2G network, the Internet speed will be relatively slow;

4. Clear the browser cache or restart the phone, the browser cache clearing method: [Browser] - [Settings] - [Clear Browser Data];

5. If the Wi-Fi network you are connected to is not your own, it may be that the speed is limited, so it is recommended to change the network and try again.

It's all going to be 5G, and 4G, who's going to maintain it! You can try it now with a 3G to make you wonder if the network is disconnected.

It might be a problem with your cellular network settings.

Here are some things to try:

2) It is recommended to take out the SIM card, use an eraser to wipe the chip of the SIM, and then reinsert the SIM card into the phone.

3) It is recommended to change another SIM card to try.

5) It is recommended that you try a firmware upgrade.

Why is 4G internet speed getting slower? 5G has nothing to do with me!

Why is the mobile phone full of 4G signal, but the network speed is very slow? Do you know these 3 reasons?

4G slow Internet speed is related to a variety of factors, such as: whether it is correctly connected to the 4G network, mobile phone settings, whether the chain collapse width exceeds the traffic limit, network coverage, the number of people who are online at the same time, etc., Peng Liang first confirms whether it can be connected to the 4G network normally, and then checks whether it exceeds the traffic limit of **, whether it is a problem with the mobile phone. Pay attention to China Telecom Guizhou customer service*** You can handle phone bill inquiry and recharge with one click, traffic, points, bills, detailed lists, etc., which is convenient and fast.

If your phone cannot access the Internet with data data, it is recommended to perform the following steps:

1. Check whether the SIM card is enabled for GPRS Internet service or temporarily closed.

To use the mobile phone data Internet function, the ** card needs to activate the data data Internet service. You can contact the local network provider of **card to open the data traffic Internet service.

2. Check whether the "Mobile Data" switch is turned on.

Slide your finger down on the top curtain of the screen and turn the "Mobile Data" dot green.

3. Please try to replace it with another ** card.

4. You can also try again in a different time period or network environment.

5. Back up the mobile phone data (**book, SMS, **, etc.), restore the mobile phone to factory settings, if the fault persists, it is recommended to send the mobile phone to the nearest service center for testing and maintenance.

Please make sure your SIM card is enabled for 4G service.

Then, please search for whether there is a 4G signal base station nearby, and the coverage of 4G signal requires a base station. At present, 4G signals are not popular, but they have only started in the three major cities of Beijing, Shanghai and Guangzhou, and the signal is strong in the city center.

If both of the above conditions are met.

Then it's a problem with the phone itself.

Internet speed has little to do with mobile phones and computer hardware, so there are few mobile phones or computers that change because of network speed problems. The speed of Internet access is mainly related to the following factors: first, the transmission medium; The second is the transmission rate.

At present, the medium of the backbone network is optical fiber, which is the best medium at present, and most places have realized optical fiber to the home, so the medium of the backbone network is beyond question. The problem is that the quality of the indoor line is worth it**, although it has been fiber-to-the-home, but the network speed from the indoor to the terminal is 4m. In addition, the transmission rate is related to the service provider, but fortunately, the mobile network has entered the 4G era.

But you have to change the 4G card, the 4G phone. China ranks 98th in the world in terms of internet speed, why? I think most of the reasons are:

First, the line is aging, the quality is not high, the layout is unreasonable, and the key is that the "last mile" problem has not been solved; The second is that the maintenance service can not keep up, many service providers only know the charge, but less service quality improvement; Third, the coverage of cellular mobile networks is not very wide, and the signal in some areas is not strong, which affects the network speed;

For example, 4G mobile phone 4G card, but where the 4G network is not covered, only 3G can be used; Fourth, from an objective point of view, China has a large number of users, and there are relatively many problems of network congestion, especially at 8-12 a.m. and 3-6 p.m. during the peak hours of Internet access. It is recommended that you avoid rush hour surfing. Service providers repairing lines or maintaining systems can also cause slow internet speeds, so you can check with your service provider. Leaving your phone uncleaned for a long time will also affect your internet speed.

Here are three pieces of advice: Playing games, especially big games, can be a drain on your network. In addition, using third-party software to test speed is not accurate, don't trust the speed test results.

Also, don't believe the Internet speed of the service trademark, that's their best means.

Select "LTE" mode to improve the 4G network of your phone.

The specific steps are as follows:

Open your phone's settings, select Network & Connections, and tap Mobile networks.

Select the access point name (APN), and then select the button behind China Mobile to modify the access point.

Go down and click on "Carrier System", select "LTE" (be sure to uncheck the "Unspecified" option), and then click OK.

Hello landlord, mobile phone.

Speed. Slow has nothing to do with the mobile phone, if you are using a 2G network, the slow speed is yes, in areas with poor signal coverage, there will be no Internet access, so this is all normal, the network speed is slow.

Base station greetings. The coverage is related to Qingxiao, not a mobile phone problem, if the landlord wants to use a faster network, you can consider using it.

3G or 4G, as well as Wi-Fi networks.

Hello landlord, 4G mobile phone Internet access is slow, and it has nothing to do with mobile phones, the reason is mainly due to the coverage of the base station. Now only China Mobile's 4G network is popularized relatively well, but it is only limited to the vicinity of the urban areas of big cities, and the speed is not very good in places where there is a little bit of He. The construction of 4G network base stations of China Unicom and China Telecom is not fast, and it is very possible that there are blind spots in coverage.
