How do telecom operators stipulate the upper limit of mobile phone number dialing?

If there is no upper limit for mobile phone dialing, you can only send text messages. The length of short messages is limited to 70 Chinese characters. If this limit is exceeded, it will be sent in several parts. Check whether all parts have been sent successfully in the SMS center. If some of them are lost, it may be due to some reasons (such as the complicated routing of international SMS signaling). It is suggested that the SMS should be controlled within 70 Chinese characters as far as possible.

If the user sends a long short message, the long short message logo takes up 6 characters, but the actual content of a short message is only 134 characters. In other words, a long short message can only calculate 67 Chinese characters from the second one.

Peer-to-peer SMS is listed as a limit number of 200 messages per hour, and 1000 messages per day (including Kuanle communication) is listed as a limit number. The holiday traffic is twice as much as usual.
