1065940 1 What do you mean by sending me four blanks in the middle of the night?

Because telecom companies need to get some data such as the usage of mobile phone cards, the sales and usage of mobile phones of various manufacturers, such as whether the mobile phones sold under the paid rental policy are used according to the binding relationship and which machine sells well, this method is adopted.

When the mobile phone leaves the factory, let the mobile phone manufacturer add such terminal registration logic. 1065940 1 is the short message number of the telecom terminal from the registration server, and the registration server receives the registration data sent by terminal devices such as mobile phones in the form of short messages.

Interpretation of terminal registration logic;

In the automatic registration process, the data terminal judges whether the parameter pair of the ESN (or pseudo ESN or MEID) of the data terminal and the IMSI of the UIM card matches the parameter pair at the last shutdown.

If it matches, the data terminal does not do any processing, and continues to perform the subsequent boot process; If they do not match, the data terminal shall report the new ESN/IMSI parameter pair, the software version of the data terminal and the data terminal model to the system through SMS according to the processing flow specified in this section.
