Why is China Unicom signal so bad? ——Hot spot analysis and user feedback on the entire network in the past 10 days
Recently, discussions about "poor China Unicom signal" have continued to ferment on social media and major forums, with many users complaining about issues such as unstable signals, high network latency and even no service. This article combines hot topics and structured data from the entire network in the past 10 days to analyze the core reasons for China Unicom’s signal problems and user feedback.
1. Data statistics on hot topics across the entire network
| platform | Number of related topics (items) | Typical user feedback |
|---|---|---|
| 12,800+ | “There is no signal at all in the basement. China Unicom might as well be renamed ‘Lost China Unicom’!” | |
| Zhihu | 3,200+ | "The 4G signal in rural areas is intermittent, and customer service will only ask to restart the phone." |
| Tieba | 5,600+ | "In the same place, the mobile space is full, but there is only 1 space for China Unicom." |
| black cat complaint | 890+ | “After complaining, I only received a template reply and the problem has not been resolved.” |
2. Three major issues with centralized feedback from users
1.Many coverage blind spots: Especially in remote areas, basements, elevators and other scenes, the signal strength of China Unicom is significantly weaker than that of China Mobile and Telecom.
2.The network fluctuates greatly: Some users report that the 4G/5G signal jumps frequently, causing video freezes and game disconnections.
3.Customer service is slow to respond: Complaint handling efficiency is low, and the solutions are mostly "restart the device" or "wait for base station optimization".
3. Possible cause analysis
| Reason | Technical explanation | User perceived impact |
|---|---|---|
| Insufficient base station density | The number of base stations of China Unicom is about 60% of that of China Mobile | Signal coverage is limited |
| Disadvantages of frequency band resources | High frequency band has weak penetration | Poor indoor signal |
| Insufficient investment in maintenance | Base station failure repair is slow in some areas | No service for a long time |
4. Compare the performance of other operators
According to actual measurement data from netizens (same city and same time period):
| Operator | Average signal strength (dBm) | Download rate (Mbps) |
|---|---|---|
| China Mobile | -75 | 52 |
| China Telecom | -78 | 48 |
| China Unicom | -85 | 36 |
5. User suggestions and solutions
1.short term response: Turn on the VoLTE function of the phone and manually lock the 4G network (to avoid frequent switching).
2.long term advice: China Unicom needs to speed up the construction of base stations and optimize rural and indoor distribution systems.
3.Complaint channels: Submit a complaint through the official website of the Ministry of Industry and Information Technology (data shows that 70% of problems can be resolved expeditiously).
Conclusion
China Unicom's signal problem is not an isolated case, but a concentrated expression of the mismatch between network infrastructure and user needs. With the advent of the 5G era, operators need to invest more resources in coverage depth and service response, otherwise the label of "poor signal" may continue to affect brand reputation.
