How to save money by texting between mobile phone number and electrical signal?

There is really no way to save money, just a normal monthly text message. If two people send more text messages, it is recommended to use QQ or WeChat. In fact, I think the team that Penguin developed WeChat must also be because texting is too expensive, and then it developed WeChat, a faster instant messaging tool, which has the functions of zero tariff, cross-platform communication, real-time input status display and so on. Compared with the traditional short message communication, it is more flexible, intelligent and cost-saving.
