What is the reason for the traffic jam?

There are several reasons for traffic jams:

1. Unstable signal strength: If the local signal strength is unstable or the network is congested, the usage traffic will be very stuck.

2. Network speed limit: If the "capacity limited" package is used, after the traffic of the main package is used up, the traffic that continues to be used will be limited by the operator and the network will be stuck.

3. Equipment problems: If the equipment using traffic is too old, unqualified, faulty or damaged, or the software has problems, it will also lead to online delays, jams and other scenarios.

4. Base station problem: Although the operator's base station will be maintained frequently, it will inevitably need to be maintained occasionally due to sudden failures, which usually makes the traffic of nearby equipment very stuck.

5. Merchant's problem: Some users buy some mobile cards online, under the slogan of low tariff and high roaming package, attracting a large number of users in into the pit. Such mobile cards often have various problems, such as speed limit, imaginary quantity, running away later, etc.

6. Mobile phone problem: If the devices that use traffic are too old, unqualified, faulty or damaged, or there is something wrong with the software, it will also lead to online delay, congestion and other scenarios.

7. Whether to use magnetic protective shell, metal protective shell, etc. Metal and magnetic materials easily interfere with signals, resulting in poor cell phone signals and affecting Internet access speed.

The above are the reasons for the traffic jam, which need to be investigated and solved according to the specific situation.
