What are the forms of short message group sending?

Generally, there are two forms, one is a virtual gateway, which is a card, and the other is a regular gateway.

The quality of short messages sent by card cannot be guaranteed, and the price is relatively low, generally 0.8 to 3 points, all of which are low. After sending a text message, a mobile phone number is displayed, and the sending quality cannot be guaranteed. Compared with the regular gateway, the card issuing rate and success rate are greatly reduced.

Regular gateways are generally suitable for sending notification messages, and the cost is high.
