Many telecom problems are not solved by one keyword. A safe troubleshooting flow usually checks the official entry, billing/contract evidence, device settings, SIM/eSIM state, roaming rules, APN, WiFi/router bottlenecks, and fallback contact channels. The references below point to deeper Chinese guides rather than repeating thin summaries.
