Adding 12520 before sending a text message is equivalent to flying letter. No charge?

The correct solution is coming: Fetion is free to use a computer to log in to the pc Fetion terminal, or a mobile phone to log in to the Fetion terminal, and send a short message through software without charging a short message fee. If only 12520 is added, it will still be sent through the G network (GSM network). There is nothing wrong with sending a text message at ordinary times, and you need to collect money. If you don't understand anything, you can continue to ask questions. I hope the above will help.
