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.

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.
