Abstract: The application provides example communication methods and systems, and example terminal devices without network service, in which more information content is allowed to be input in a short message. In one example method, in response to a first operation instruction on a first interface, the first terminal device displays a second interface including multiple text labels. In response to a selection operation for at least one text label in the multiple text labels, the first terminal device displays a third interface including message preview information obtained based on the at least one text label. In response to a second operation instruction on the third interface, the first terminal device sends information to a recipient based on the message preview information, and displays a fourth interface indicating an information interaction interface between the first terminal device and the recipient, where the information interaction interface is displayed after the information is sent.

Abstract: A first interface comprising a call screen is displayed on an electronic device. First prompt information is displayed on the first interface following receiving information about a first red packet, the first prompt information provides a prompt to open the first red packet. Opening detail information of the first red packet is displayed on the first interface following an input for the first prompt information.
