Samsung mobile phone can't receive SMS. I haven't received the information from Unicom for more than ten days. I usually receive SMS traffic reminders every day.

You can't receive SMS or verification code due to the following reasons:

1, check whether the mobile phone number has been enabled for SMS sending and receiving, and contact customer service for inquiry;

2, check whether the mailbox is full, if so, please delete some information;

3. I still can't get it after deleting it. It is suggested to change the phone or card to see if it is a hardware factor or a mobile phone problem.

4. Set SMS interception on the mobile phone to see if it is intercepted as spam;

After eliminating the above reasons, you can try to test whether it can be received in other places to see if it is the reason for the weak local signal.

If the above problems do not exist, it is recommended to contact local manual customer service to handle this problem.
