How many short messages can ec send at a time?

Generally, the number of mobile phone cards can't exceed 200 per day, and the specific restrictions are subject to the reply of telecom operators.

When the number of short messages sent by users on the same day is too large, the card will be locked, resulting in the inability to send short messages on the same day.

Reason: In order to prevent the intrusion of spam messages on mobile phone users, the three major telecom operators in China will limit the number of messages users send every day.
