What is the website where China Mobile can send short messages online?

You can send short messages for free by flying mail on your mobile phone.

You can download Fetion, which can be found in the application management of mobile phones, but the sending object must be your Fetion friend, which means that the other party should also enable Fetion function. You can also log in to the mobile 139 mailbox. You can send text messages to anyone you want, as long as you have the other person's number.
