How does Fetion send short messages for free?

After successfully adding the other party as a friend through Fetion, you can use the Fetion PC client to send short messages to the other party's mobile phone for free;

You can also log in to the mobile client and send short messages to friends in the friends list, and there is no "short message fee", but GPRS traffic will be generated, and the traffic fee is included in the GPRS package. If you apply for a GPRS package, you can also save money by sending messages to your friends in this way.
