My mobile phone is a flow card, so it costs very fast. I haven't received any text messages recently.

If you don't receive SMS or verification code, it may exist in the following situations:

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

2. If you still can't get it after deleting it, I suggest you change the machine or card to see if it is caused by hardware;

3. Check whether it is intercepted by mobile phone interception software;

4. Check whether the cell phone signal is normal and try to test whether it can be received in other places.
