It could be a problem with your phone, or it could be a problem with the place you're in.

Mobile phones carry only one or two bars of signal, and the possible reasons are as follows: telecommunication networks are susceptible to weather and electromagnetic interference, as well as signal shielding, so sometimes the signal is not good. The quality of the telecommunications network is not good enough, the coverage is not large, and there are still some areas and provinces that do not have 3G and 4G networks.

The location signal is weak or the signal is blocked.

Introduction: Telecommunication refers to the use of electronic technology to transmit information between different locations. Telecommunications encompass different kinds of long-distance communication methods, such as:

Scale: In terms of overcoming distance barriers, telecommunications have become irreplaceable and most widely used modern communication tools, such as wired and wireless, fax, radio broadcasting, television, Internet; In terms of overcoming the time barrier, telecommunication has also reached the point where it competes with books, newspapers, and periodicals.

Expansion: The history of humans using electricity to transmit information began with the telegraph. The telegraph is a way of transmitting information in symbols, the so-called digital method, but after the invention of the telegraph in 1876, in the field of telecommunications, the analog method has an absolute advantage.

In the 50s of the 20th century, the emergence of PCM technology made the digital communication mode see a ray of light. But its real growth and development, and even its domination of the world, mainly relied on the power of electronic computers.

Hello dear, I'm glad I can answer for you. Regarding the original reason for the telecom card signal to be full and there is no network, and the solution is as follows: If you find that the mobile phone is turned on and the mobile data is still unable to access the Internet, you must first check the status of the mobile phone, and if it is in arrears, you only need to pay the fee as soon as possible. 2. The base station of telecommunications is overloaded, and the base station is not omnipotent, and it also has its own carrying limit.

When a large number of devices are connected in a short period of time, there is a possibility that the competition will be crowded, resulting in the inability to access the Internet normally, which often occurs at large-scale events such as concerts. 3. 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 turn off the network data button several times, if there is still no network, it is recommended to call the customer service of major operators to ask and solve the problem. 4. If the mobile phone network parameters are wrong, the mobile phone cannot access the Internet normally, and it is also possible that the mobile phone network parameters are wrong.

You can try to turn on the airplane mode to search for the network signal again, if it still can't be solved, it is recommended to send it to the after-sales service store or find a professional to reconfigure the network parameters. 5. Traffic monitoring is limitedMany people will use some software to monitor the use of mobile phone traffic, once the upper limit of traffic usage is exceeded, the mobile phone will prompt automatic disconnection of the network, in order to achieve the purpose of saving mobile phone traffic. If you need to surf the Internet, you can change the data package value or disable the automatic network disconnection function.

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, if the mobile phone signal is unstable, it is recommended to change the phone and card test; In addition, you can check whether the data function switch is set normally and whether the network selection is in the 4G network. If none of the above is resolved, it is recommended to contact the local telecom customer service directly for feedback and verification. Anhui Telecom*** is at your service.

Normally, 4G uses a 1800 or 2100M signal, and the signal strength is not as strong as 800M 2G.
