Does the country stipulate that mobile phone users will automatically block 50 consecutive text messages?

When the number of telecom short messages exceeds 50 per hour or 300 per day, the system will automatically block the short message function of this number and automatically resume the next day; If Unicom customers send more than 300 SMS messages per hour and more than 1000 SMS messages per day, the SMS function of this number will be restricted immediately, and no more SMS messages can be sent until the customer applies for recovery.

Mainly to ensure information security and crack down on spam messages, pornographic messages and black messages.
