In one embodiment, a method includes a content provider (e.g., a social-media network) receiving an event notification from a network-operator system (e.g., a cellular-service provider) with which a user has a data account. The event notification may include status information associated with the user's data account. The content provider may receive a content request from a client device of the user. Based on the status information associated with the user's data account, the content provider may determine content to transmit to the client device in response to the content requests. The content provider may then transmit the content to the client device through a network associated with the network-operator system.
