Telecom mobile phones can send short messages, but they can't receive them.

If the SMS is not received, or the verification code may exist in the following situations:

1, check whether the mailbox is full, and if it is, 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.

After the above reasons are eliminated, it still cannot be used normally. Please contact the local manual customer service to handle this problem.
