Guangdong government's mobile phone number is invalid.

1, new mobile phone number segment/number: due to the rapid growth of mobile phone users, in order to meet the number of users, major operators have opened new number segments, such as 147, 180, 175, 149,/kloc-. This number has just been listed, and most merchant platform databases have not added this information, so it will be invalid when it is issued.

2. Virtual number: Some users will use one card with two numbers (that is, a real number and a virtual number) to achieve anti-harassment, job classification, number hiding and other services. At this time, if the virtual number is used as the number to receive the short message, it will not be recognized by the system.

3. virtual operator: virtual operator is like an agent. They contracted the right to use some communication networks from three basic operators: China Mobile, China Unicom and China Telecom, and then sold communication services to consumers through their own billing system, customer service number, marketing and management system, thus having a specific number segment of 170. Because this number segment is similar to a "rental" service, some numbers are unrecognizable.
