There are the following reasons why you can't receive the SMS or verification code:

One, you can first check whether the cell phone mailbox is full, if so, please delete part of the message;

Two, after deleting and still can't receive it, you can change the machine or change the card to test, to see whether it is the hardware factor;

Three, after ruling out the above reasons, you can try to test whether it can be received in other places to see whether it is the reason of weak local signal. If the signal is weak, you can try to receive it in other locations to see if the signal is weak in your area.
