How many text messages can a mobile phone number send a day at most? I heard that it is beyond the function of being blocked by SMS, right?

A mobile phone number can be sent at most 1000 in a normal day. If it exceeds, it will be blacklisted and the SMS function cannot be used.

In fact, in order to reduce the intrusion of spam messages on every mobile phone user, the three major telecom operators in China will limit the number of SMS messages sent by users every day.

No more than 200 articles per hour on non-holidays, and the total amount per day does not exceed 1000 articles;

During holidays, the number of articles per hour shall not exceed 500, and the total number of articles per day shall not exceed 2000.

Ps: Customers exceeding the above-mentioned quantity limit 10% are put on the monitoring list, and the information function will be suspended if they exceed 10%.
