| Ranking | Topic keywords | Number of discussions (10,000) | Main platform |
|---|---|---|---|
| 1 | China Unicom network lags | 12.8 | Weibo, Tieba |
| 2 | 5G signal is unstable | 9.3 | Douyin, Zhihu |
| 3 | High latency in mobile games | 7.5 | Station B, Hupu |
| 4 | Video loads slowly | 6.2 | little red book |
2. Types of high-frequency problems reported by users

| Download speed fluctuations | 5% | "Speed dropped from 10MB/s to 200KB/s" |
3. Possible cause analysis
1.Base station load surge:The summer traffic peak is superimposed on popular mobile games/events (such as "Genshin Impact" 4.0 version update, LPL playoffs), and base stations in some areas are overloaded.
2.Impact of network upgrade:China Unicom recently carried out 5G SA network cutover in 23 provinces and cities, and some users reported signal fluctuations during the cutover.
3.Terminal compatibility issues:Users of some older models (such as Huawei P30 series) reported network adaptation abnormalities after upgrading the system.
4.Interference from external factors:Extreme weather (the passage of Typhoon Dusuri) caused damage to optical cables in many places, affecting transmission quality during the maintenance period.
4. Operators’ response measures
| measures | Implementation scope | Effective time |
|---|---|---|
| Expanding base station bandwidth | 15 cities including Beijing, Shanghai, Guangzhou and Shenzhen | From August 15th |
| Optimize DNS resolution | Nationwide | Completed |
| Launch of "Extreme Speed Protection Package" | Game high latency users | Launched on August 20th |
5. User self-service solutions
1.Network diagnostics:Dial 10010 and press key 5 to trigger automatic optimization, or use the "China Unicom APP"-"Network Detection" function to troubleshoot the problem.
2.Parameter settings:Manually configuring the DNS to 223.5.5.5 (Alibaba Cloud public DNS) can improve the web page opening speed.
3.Time period selection:Avoid downloading large files during the peak hours of 20:00-22:00.
4.Equipment maintenance:Clean the cache on your phone regularly (once a week is recommended) and turn off the background automatic update function.
6. Industry comparison data
| Operator | Average latency (ms) | Download rate (Mbps) | Complaint growth rate |
|---|---|---|---|
| China Unicom | 68 | 48.2 | +17% |
| move | 59 | 52.1 | +9% |
| telecommunications | 63 | 50.7 | +12% |
Note: The statistical period of the above data is from August 10th to August 20th, sourced from Speedtest Global Index.
Conclusion:Network lag is often the result of the superposition of multiple factors. It is recommended that users try targeted optimization based on their own usage scenarios. If the problem persists, you can provide feedback through the Ministry of Industry and Information Technology’s complaint channel (official website or 12300 hotline). China Unicom officially stated that it expects to complete the network optimization work in major cities across the country in early September, and the experience will be significantly improved by then.
