Send a text message and it won't be sealed for a few minutes.

At present, the three major domestic operators will limit the number of messages sent by users every day: no more than 200 messages per hour on illegal holidays and no more than 1 message per day; During legal holidays, the number of articles per hour shall not exceed 500, and the total amount of articles per day shall not exceed 2.

If it is a mobile phone that sends short messages in batches, under the current rules, the number that can be sent is very limited, which is not limited by the function of the mobile phone. From the function alone, it is no problem to send text messages to hundreds of people in batches at a time. The problem lies in the operator's control over the mass short messages sent by mobile phone cards. In order to prevent harassment and fraud, mobile phone cards have gone to the real-name registration system, personal mobile phone numbers can no longer be used for telephone and SMS marketing, and mobile phone card group texting may be stopped at any time.
