Why can't Nokia send messages with Unicom card?

There are many possibilities that mobile phones can't send text messages. You can check according to the following points:

1. SMS service is not enabled on the mobile phone. You can call 100 10 to contact customer service or go to the local business hall to activate this function.

2. If the SMS center number is not set or set incorrectly, just reset it;

3. The signal is weak, there is no signal or the battery of the mobile phone is insufficient, resulting in the information not being sent normally;

4. Because the system is busy, especially during the peak period of texting on holidays, it is suggested that you try again later or avoid the peak period of texting;

5. The sending format is incorrect. If you send a short message to PHS users, you need to add the area code before the number;

6. SMS sending and retention is valid for 24 hours;

7. Whether the SMS inbox and sending box are full;

8. It is recommended to restart the machine or change the phone to test it.

In addition to the above simple troubleshooting, it still cannot be solved. You can contact Unicom customer service for processing.
