Neither of the two cards in my OPPO phone can receive short messages. Is it the phone? There is no problem with the center number, and the mobile phone card is not in arrears.

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.

If the above reasons can't solve the problem, I suggest you contact Unicom's manual customer service to verify the handling. The actual situation is subject to local policies.
