Technical terms of short message service

This is also called virtual short message, which is relative to the gateway. In general, GSM short message equipment is used for card sending, or single port or multi-port. Large virtual mass distributors usually have hundreds of such devices. But even if there are more equipment, we should send them one by one.

The number received by the called party is the mobile phone number showing that the GSM card is inserted into the equipment of the mass sender.
