How to withdraw the sent information?

There is no way to withdraw the sent SMS. Short message is a telecommunication service in digital mobile communication system. It is a non-real-time, non-voice data communication service that transmits text or digital short messages through the signaling channel and signaling network of mobile communication system.

Disadvantages of SMS:

1, with small information capacity

Short message platform is relatively boring because it can only edit text and lacks corresponding picture materials, and short message advertisements are rampant, so the reading rate is not necessarily too high. The sending cost of MMS is too high.

2. It is difficult to collect terminal data.

SMS platform needs corresponding numbers to send, and how to collect these numbers and how to send them to those customers after collection has become a very important issue, so the customer coverage of SMS platform is not necessarily comprehensive.

3. Transmission is limited

Generally, the number of SMS platforms is limited, thousands or even tens of thousands. It is basically impossible to send messages after 8 pm, and its flexibility and management are not as good as that of SMS power grid.
