How can I send a text message directly to someone else's mobile phone?

If he sends it to you by airmail and you don't, you can reply directly and show it in his airmail. If you have, so much the better. If you send it directly to him, he will show it online in his fetion. If he is offline, send it to him as an ordinary message. This is the advantage of Fetion. No matter he is not online, he will restore your information!
