The three basic telecom enterprises (China Mobile, China Unicom and China Telecom) are required to go to the place where the number belongs with the valid certificate of the owner, but not to other places.
When the mobile phone card is cancelled, the basic telecommunications enterprise shall verify the user information such as user name, product package, contract plan, bill, pre-deposit, arrears, etc. Since the opening of mobile communication service, in order to ensure the security of user accounts, prevent risks, avoid the occurrence of malicious off-site cancellation by criminals and better safeguard the rights and interests of users who cancel their accounts, basic telecommunications enterprises have carried out information verification of user data at the place where numbers belong.
Due to system design and other reasons, the business support system of provincial companies of basic telecom enterprises can't support the comprehensive verification of user data in different places, and three basic telecom enterprises (China Mobile, China Unicom and China Telecom) can't provide mobile phone card cancellation service in different places.
