Can I send short messages to my mobile phone with my computer?

Yes, the computer sends a message to the telecom gateway through the Internet, and the gateway will send the message to the mobile phone.

For example, many advertisements you receive are very long, and they are basically sent online. But this service is to apply for telecommunications, which is very expensive for individual users. There used to be a chat software called Netease Popo. You can change as many coins as you like online, and you can also send short messages with these coins for free.
