What is a mobile phone random number?

Mobile phone random code is a code automatically generated by mobile phone system. When logging in online, the verification code sent to the mobile phone is only used once.

The reason why mobile phone short messages can't receive garbled codes;

1. Check whether the mailbox is full first, and try again if some information is deleted;

2. If it is still not received after deletion, you can change the machine or card to see if it is a hardware factor;

3. You can check it in the SMS trash can first;

4. Because there are many users, the speed of sending SMS is slow. You can try again later.

5. After eliminating the above reasons, try to see if it can be received in other places to see if it is the reason for the weak local signal.
