网间短信指的是不同网络之间的短信互通，也就是不同运营商之间的短信业务。在过去，不同运营商之间的短信互通需要经过繁琐的网关转换，而现在，随着技术的不断发展，不同运营商之间的短信互通已经变得更加便捷。

网间短信的出现，使得不同网络之间的用户可以更加方便地互相发送短信，进一步扩大了短信业务的覆盖范围。同时，由于不同网络之间的用户可以更加方便地交流，也促进了不同运营商之间的合作与融合。

目前，中国的网间短信已经实现了全面的互通。用户可以在不同的运营商之间自由地发送和接收短信，无需任何额外的手续费用。这种互通模式的实现，不仅方便了用户之间的交流，也进一步推动了中国的信息化进程。

Inter-network SMS refers to the mutual communication of short messages between different networks, also known as the short message service between different operators. In the past, the mutual communication of short messages between different operators required cumbersome gateway conversion. Nowadays, with the continuous development of technology, the mutual communication of short messages between different operators has become more convenient.

The emergence of inter-network SMS allows users from different networks to send short messages to each other more easily, further expanding the coverage of the short message service. At the same time, as users from different networks can communicate more conveniently, it also promotes cooperation and integration between different operators.

Currently, inter-network SMS in China has achieved full interconnection. Users can send and receive short messages freely between different operators without any extra service charges. The implementation of this interconnection model not only facilitates communication between users, but also further promotes China's informatization process.
