The other party is not a Fetion user. Can I send him a flying letter by computer?

You can send a flying letter to the other party, but you should charge the SMS fee normally.

Fetion sends messages and the fees for messages are as follows:

For mobile Fetion customers: If you choose to send messages in the chat window, it is free. If you choose to send a text message, it is free to send it to your friends in a flying letter. Friends or non-friends sent to China Unicom and Telecom Fetion are charged.

For Fetion customers of China Unicom and China Telecom: If you choose the chat window to send messages, it is free and unlimited, but the other party needs to log in to Fetion software to receive them. If the other party is not online, you will receive it the next time you log in. If you choose to send short messages, you can send 50 free short messages to your Fetion friends every month for free. Unable to send Fetion SMS to Unicom, Telecom and mobile users who have not been added successfully. If you exceed the number of free text messages, you can exchange points for short message packages.
