What if the newly bought Unicom card can't send and receive text messages? I am very anxious

The processing method of mobile phone unable to send SMS is as follows: 1. You can change your mobile phone to see if you can send and receive text messages; 2. If you can send and receive short messages, I suggest you plug the card back into your mobile phone and send yourself a short message to see if you can receive it. 3. If not, I suggest you check whether there is a problem with the sim card; 4. Check whether the number of the SMS center is set correctly; 5. Bring the mobile phone card to the local business hall for testing or replacement. If your mobile phone can't send short messages, you can try to restart or change your mobile phone for testing to see if the following conditions exist:

1. The SMS center number is set incorrectly, please re-enter the correct SMS center number; 2. No signal or low battery; 3. Because the system is busy during the holiday short message sending peak period, it is suggested that you try again later or avoid the sending peak period;

4. The sending format is incorrect. If you send a short message to PHS users, you need to add the area code before the number; 5. The short message sending time exceeds 24 hours; 6. The mobile phone shields the short message sending function; 7. Blacklisted by SMS; 8. Insufficient quantity balance; 9. SMS inbox and outbox are full. If the above reasons cannot be solved, you can contact the local manual customer service or go to the business hall to confirm whether the SMS function is enabled and hand it over to the staff.
