Is it free to send messages to each other in a flying letter? Is it free no matter how much? There are restrictions?

Hello, Fetion is a chat tool, which can guarantee to receive messages in real time. If you don't log in to the Fetion client, a friend will send you a message and you will receive it. When the Fetion service is launched, the monthly function fee is free, which is charged in three cases: 1. You log in to the Fetion client through the computer to send Fetion messages to Fetion friends. There is no charge on the mobile phone, but if you send Fetion messages to non-Fetion friends, you will be charged the normal SMS fee; 2. You log in to the Fetion client through your mobile phone and send messages to Fetion friends, and charge the mobile Internet traffic fee. However, if you send a Fetion message to a non-Fetion friend, in addition to the mobile Internet traffic fee, you will also charge a normal SMS fee. 3. If you use Fetion service by SMS, you will be charged according to the normal SMS service.

If you chat in Fetion, both parties will charge a fee, and they will charge a fee when they are busy. If you are a Beijing mobile number, you are in Beijing: 0.25 yuan/minute during busy hours (8: 00-18: 00); Leisure time (18: 00- 8: 00 the next day) 0.15 yuan/minute. When roaming in China, the flat rate is 0.5 yuan/minute, regardless of busy or idle hours. Thank you for your support to China Mobile, and wish you a happy life!
