My WeChat has no SMS verification code. What should I do? What is the reason?

According to the information provided, the reasons for not receiving SMS or verification code are as follows:

1. Please check whether the mailbox is full first. If it is full, please delete some information.

2. Whether the mobile phone service status is normal;

3, fill in the receiving SMS number is correct;

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

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

If the above problem does not exist, please contact the local manual customer service to handle this problem.
