What should I do if I can't receive the port number transfer verification code? Has the port number transfer verification code been solved?

Generally speaking, the verification code is published by the platform of third-party service, which has nothing to do with the portability of mobile and telecommunications. When the number is carried from mobile to telecom, the third-party platform does not dock the business in time, so it will not receive the verification code. At present, ICT Institute is actively upgrading its system with third parties, such as Alipay, banks and various institutions, all of which are involved in this issue. Therefore, in the port number transfer network, we should treat this problem carefully to prevent it from affecting our own business.

Why can't I receive the verification code after port number transfer? The main reason is on the platform of short message center.

At present, a large number of verification code short messages are sent through the short message center platform, which has the interfaces of three major operators, and the numbers belonging to different operators are sent through different interfaces. The SMS center platform judges which operator the number belongs to, that is, according to the number segment, for example, 139 is China Mobile, 186 is China Unicom, and 189 is China Telecom.

Because the number segment has not changed after the user transfers the number to the network, but the operator has changed, there will be a situation that the SMS is sent to the wrong operator, that is, for example, if you switch from mobile to telecom, the SMS center platform will still send your verification code to China Mobile, and the user may not receive it.

What if I don't receive the port number transfer verification code? What should users do if some important verification codes are not received after port number transfer? In fact, there are still many functions inside. When users can't receive SMS verification code, they need to call the operator's customer service for feedback.

It is also necessary to synchronize information after the network is transferred to the SMS service provider. Under normal circumstances, the SMS information of SMS service providers and users needs to be synchronized, sometimes it is delayed, and sometimes it needs to wait, so we can continue to wait for a while to see if we can receive the SMS verification code.

The verification code of port number transfer was still unresolved on February 3, 20 19, and the port number transfer users still could not receive the short message after successfully bringing it in. There are three main situations.

The first type: you can't receive the SMS sent by the operator's customer service number. For example, after China mobile users brought into China Unicom, they could not receive the traffic reminder SMS sent by 100 10, online business hall verification code, etc.

The reason for this problem is that the importing party (China Unicom) did not get the information of the importing user from the CSMS platform (port number transfer management system) of the Ministry of Industry and Information Technology in time, and mistakenly thought that this number was a different network number.

There is a delay of 2-3 hours from the successful transmission of the port number to the information obtained by the operator.

For example, China Mobile's A number was successfully transferred from mobile to China Unicom at 9: 00 on February 1 day, so within 2-3 hours, the SMS Center of China Unicom Group did not know that A number had been brought into China Unicom, and still handled the China mobile number according to A number (discarded SMS).

Second, the problem of not receiving the verification codes of third-party short messages such as banks and websites is caused by the third party that sent the short messages. Some third-party SMS sending functions are not perfect, which leads to users who transfer to the network not receiving SMS verification code. Because according to the overall technical scheme of the Ministry of Industry and Information Technology, all enterprises that use SMS need to reform the SMS sending mechanism. From the initial judgment of the operator according to the user number segment to the CSMS system of the Ministry of Industry and Information Technology, the number belongs to the operator.

For example, before the implementation of port number transfer, when hungry websites send SMS verification codes, they should first judge which operator it is according to the number segment of the mobile phone number (186/139/133), and then call the "industry SMS gateway" of the corresponding operator to send SMS verification codes. After the implementation of number portability, before sending each verification code, you need to go to the CSMS system of the Ministry of Industry and Information Technology to find out which operator the number belongs to, and then call the "industry short message gateway" of the corresponding operator to send a short message.

The third type: you can't receive short messages from peer numbers in different networks. For example, after China Mobile's A number is transferred to Telecom, you can't receive the short message sent to A by Unicom's B number. This problem mainly lies in the telecom network management system. It was the SMS center in the network management system that didn't update the port number transfer data in time, and mistakenly thought that A was still the number of China Mobile, which led to A's failure to receive it.

The above problems are not common, and there are some accidental factors. Once these problems are found, they can be solved in a short time as long as they enter the operator's customer service hotline.
