A traffic package providing method, wherein the method comprises: obtaining, by a terminal device, travelling schedule information, wherein the travelling schedule information comprises N travelling schedule nodes, N is a positive integer greater than 1, and the terminal device is a terminal device that supports an embedded universal integrated circuit card eUICC; sending the travelling schedule information to an access platform server; receiving information about multiple traffic packages that is sent by the access platform server, wherein each of the N travelling schedule nodes is corresponding to information about at least one traffic package in the information about the multiple traffic packages, and the information about the multiple traffic packages is provided by an operator; determining, from the multiple traffic packages, a target traffic package to be used by the terminal device in each of the N travelling schedule nodes; sending a traffic package subscription message to the access platform server, wherein the traffic package subscription message comprises an identity of the determined target traffic package and identity information of the terminal; characterized by obtaining N profiles, wherein the N profiles are corresponding to the N travelling schedule nodes in a one-to-one manner; and installing the N profiles on the eUICC, wherein the obtaining N profiles comprises: receiving a traffic package subscription response message sent by the access platform server, wherein the traffic package subscription response message comprises a token, and the token is used to indicate the N profiles; sending a download request message to the access platform server, wherein the download request message comprises the token; and receiving a download request response message sent by the access platform server, wherein the download request response message comprises the N profiles, wherein the travelling schedule information further comprises N travelling schedule times that are corresponding to the N travelling schedule nodes in a one-to-one manner, and the installing the N profiles comprises: sequentially installing the N profiles according to a quantity of profiles that can be installed on the eUICC of the terminal device and according to a sequence of a travelling schedule time corresponding to each of the N profiles, and deleting an invalid profile. obtaining, by a terminal device, travelling schedule information, wherein the travelling schedule information comprises N travelling schedule nodes, N is a positive integer greater than 1, and the terminal device is a terminal device that supports an embedded universal integrated circuit card eUICC;
