How to cooperate with SMS interfaces of three major operators

To connect the SMS interface of the operator, the following conditions must be met first:

First, I need a certificate with the code number 10690 issued by the Ministry of Industry and Information Technology, including the certificates of the whole network and the provincial network.

Second, enterprises need SP certificate (value-added business license).

Third, the docking mobile interface needs local companies (China Unicom and telecommunications are not needed for the time being).

Meet the above conditions and then find three major operators to cooperate (sign a contract) and then call the SMS interface of the operators.

If you just call the operator's customer service number, they will tell you that there is no such service. In fact, this business is not an ordinary business, so many people don't know it.

If your delivery volume fails to meet certain requirements, the operator will not cooperate with you. You can find the SP certificates and interfaces of the three major operators on this website. I hope it helps you.
