What if whatsapp can't send a verification message?

You can't receive SMS or verification code due to the following reasons:

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

2. If you still can't receive it after deleting it, you can change the machine or card to see if it is a hardware reason.

3. 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 none of the above problems exist, it may be related to the network function, please contact the local manual customer service to deal with this problem.
