What's the difference between sending short messages by gateway and sending them by card?

1, the price is different: the cost of gateway SMS is higher than that of card SMS.

2. Different sending speed: Generally speaking, the sending speed of gateway is faster than that of mobile phone, which is the product of short message group sending. Gateway can open a large number of ports to work at the same time, and the sending speed is naturally faster, but the sending speed of mobile phone depends on the equipment investment (that is, economic strength) and technical strength of SMS group sending platform.

3. Different sending methods: SMS sent by the mobile phone is the information sent by the mobile phone card purchased in the market (the source of the SMS received by the other party is the mobile phone number from a random source), and zd Gateway SMS is a short message product launched by the communication department.

4. There are different restrictions on short message group sending: at present, most gateways restrict sending commercial advertising information, while mobile phone sending is relatively flexible in this respect. Powerful group sending companies can basically send commercial short messages except illegal short messages.
