What is "on-hook SMS"?

On-hook SMS means that when someone calls a fixed phone with a mobile phone (telecom, mobile, Unicom) and hangs up, the system will send pre-set advertising content to the mobile phone calling the fixed phone according to the called state (such as connected, busy, no answer, etc.). ), this is a very good way of advertising. We also provide an operating platform, which can set short message content and send short messages in groups according to the needs of publicity. In addition, the platform can also be used to query and set up SMS, call records, package modification and missed message reminders.
