Analysis of problems in port number transfer network;

The delay and loss of short messages after port number transfer is actually related to the current forwarding mechanism. At present, the three major communication operators have a common portability database. After accessing the database through the third-party interface, Internet providers can determine which number is portable and take targeted measures when sending short messages. It is reported that head Internet companies such as Tencent and Ali have access to this portable database.

In addition, there is an underlying forwarding channel for SMS services. In other words, even if your number is transferred out, when a verification code is generally needed, the service provider will send it back to the original operator, and the original operator will forward it to the final number through the bottom layer. Therefore, in this process, the forwarding service quality of the original operator will also affect the personal experience.
