How to send a letter by mobile phone .. Help me answer some questions.

1, first look at the version of your mobile client. If the version is too low, you can't send a message to the other party without fetion.

If the version is not low, you can send him a message even if he doesn't have a flying letter.

2. If the other party's Fetion is online, he will receive it directly at the Fetion client.

If his Fetion is in the state of leaving, and the mobile phone and the client are set to receive Fetion information at the same time when leaving, then he can receive it on both the flight client and the mobile phone.

If he didn't open the Fetion client, he received it on his mobile phone in the form of a short message.

The sending number of ordinary SMS is your mobile phone number, but if you send it by fetion, he will receive 12520 and add your mobile phone number.

4, 5, if he calls back your mobile phone number, you will receive a text message.

If he returns your flight number (12520 followed by your mobile phone number), he will receive it by airmail. If your Fetion is not opened, he will receive the message on his mobile phone.

6. That depends on how many words you send. A word has two bytes, 1kb= 1024 bytes.

Call customer service and ask how much a KB (bit) costs.

If you don't send text messages at the client.

That's the money for texting

So the seventh question is the money for text messages.
