Embodiments of the present invention provide a data sending method and device. When a first terminal and a second terminal communicate with each other by means of instant messaging through the Internet, if it is determined that communication can be performed through a first wireless communication network, the first terminal and the second terminal establish a wireless communication connection based on the first wireless communication network, and perform data interaction through the wireless connection. In this way, the influence of the network bandwidth of the Internet is eliminated, and the data transmission speed and efficiency are improved. |
