Which company is the SMS operator sp of China Mobile?

There are many SMS operators, all under the mobile name. It means that I use mobile resources (servers and users) and then share the profits.

These operators have records on the move, and their phone numbers and contact information can be found.

For example, you can see some sp codes in your dream list. Call 10086 to find the contact number of these codes and what company they are.

Common ones are Tencent and linkage advantages. (unprofessional, I didn't remember a few. )
