Samsung S8 can't receive SMS, please ask for help.

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.
