Be careful when registering TG with a Chinese mobile number.

At the 12th China International Police Equipment Expo, the Ministry of Public Security's Third Institute officially showcased a Telegram monitoring system that has been deployed in real combat. It is reported that the system has collected over 30 billion pieces of data, covering more than 70 million +86 registered accounts and 390,000 group channels.

This is not just "potential capability," but a truly operational national-level intelligence system. It captures public group chat content through APIs and bot crawlers, integrates social graphs, semantic models, and device fingerprint analysis to identify user behavior and real identities. Once tagged with an "attention" label by the system, long-term tracking is implemented.

Here's the key point:

All TG accounts registered with a +86 phone number are archived by the backend from the moment of registration;

Even if you change your phone or account, the system can re-tag you through device ID, language preferences, and usage habits;

The system can access carrier's real-name information, linking you with the name and family relationships associated with the phone number;

Cross-platform integrated analysis (such as WeChat, Weibo, Taobao, 12306) makes it impossible for your online activities to "detach."

Additionally, extreme measures such as SIM card hijacking, counterfeit client Trojan injection, social engineering phishing, and manual offline comparison are listed as reserve strategies.

What to do?

For ordinary users who do not want to be precisely identified, it is recommended to completely avoid using a +86 phone number to register for Telegram, only download the client from the official website, enable "secret chat" and two-factor authentication, avoid participating in any public groups involving sensitive topics, and regularly clear chat history.

The target of this system is not "what you said," but "which circles you are in." The real risk does not come from the speech itself, but from the fact that you have been precisely labeled and modeled by the system, becoming a "key predictable risk group."

Do not consider Telegram as a safe haven; it may not keep you safe.
