Can I check the related card with one card?

I can't inquire because the IOT card is equivalent to a bearer card.

The National Mobile Phone Card "One Certificate General Search" is a public service jointly launched by the Anti-Fraud Center of the Ministry of Industry and Information Technology (China Xintongyuan), China Telecom, China Mobile, China Unicom and mobile communication resale enterprises, which can provide users with the numbers of all mobile phone cards that are online through their resident ID cards.

These include China Mobile, China Unicom and China Telecom, which we are familiar with. There are also 39 plus virtual operator, such as Alibaoka rice noodle cards, which are not familiar to the public at ordinary times.

The national mobile phone card "one certificate for general investigation" is mainly aimed at domestic mobile phone users. Users can enter their names, ID numbers and mobile phone numbers through online business halls, webpages, applets and official WeChat accounts.

After the input verification code passes the authentication, the service platform inquires the number of mobile phone cards under the user name from the basic telecom enterprise and the mobile communication resale enterprise respectively, and the service platform replies the user's inquiry result through the unified short message port 10699000 within 48 hours.

The query results only include the number of mobile phone cards in network status, excluding fixed telephones and cancelled mobile phone cards.
