What's the telephone number of China Telecom SMS Center?

The number of SMS centers varies from place to place. You can call 10000 for consultation. It's free to call 10000 with a telecom mobile phone or landline.

The number of the information center is the short message server. If it is not filled in correctly, the SMS cannot be sent successfully. Each region has its own information center number. Please consult your local network operator for the specific number.

Reflections on data verification of SMS central office;

According to the function division of the operator's short message center, the MO short message center in each province is usually equipped with the number segments of network users in the province (the provinces with large business volume are also divided into cities), so according to the situation of each province, each MO short message center is equipped with all the number segments in the province at most.

Therefore, as long as the number segment list corresponding to this data can be extracted from the standard bureau data of the headquarters and compared with the authentication number segment data information derived from the existing network, the difference between the two can be obtained.

The number segments normally allocated to the provincial level are all ten thousand segments, but due to the large amount of data, the allocation is completely irregular; The number segments allocated by provinces to cities are even more complicated, even subdivided into thousands of number segments.

Although it is only to check the number segment data of SMS centers, due to the different configuration data formats of SMS centers of various manufacturers, if it is necessary to check the number segment data of various manufacturers, it is necessary to extract important information such as number segment, number segment type and attribution city from the configuration of SMS centers in various provinces, and check with the number segment information of corresponding provinces in the standard number segment file issued by the headquarters to find out the discrepancy between them.
