Seek the master! How does the system prompt that the number of short messages sent by Fetion reaches the upper limit?

Hello, you can send messages to Fetion friends through Fetion PC client. The number of messages is limited (only sent by the other party's mobile phone). Each number can send up to 600 messages for free every day and up to 10000 messages for free every month. If the number exceeds the limit, messages cannot be sent through the PC client in the current month. There is no limit to the number of short messages sent to friends through the mobile phone client, and there is no graphic verification mechanism. If you send ordinary short messages to non-Fetion friends through Fetion PC client, the upper limit is 50 messages per hour; Limit 50 articles per day; Monthly limit 1000, which will be capped if any item is reached.
