The invention provides a hot spot sharing authorization method, a terminal device and a server. The hot spot sharing authorization method includes the following steps that: a hot spot sharing enabling instruction triggered by a user is received through the terminal device; a hot spot sharing authorization request is sent to the server, wherein the authorization request contains the user identification code of a terminal user; an authorization result sent by the server is received; if the authorization result indicates that authorization is successful, the hot spot sharing enabling instruction is executed; and if the authorization result indicates that the authorization fails, the hot spot sharing enabling instruction is ignored, wherein the authorization result is sent by the server according to judgment on whether hot spot sharing is allowed to be enabled according to user data access plan information after the server obtains the user data access plan information corresponding to the user identification code according to user identification code query. With the hot spot sharing authorization method adopted, whether the hot spot sharing function of the terminal device is authorized is judged according to the user data access plan information at the server side, and the hot spot sharing function of the terminal device can be monitored, and the paralysis of a communication network can be avoided.
