Why can't Unicom gsm card send information? How do I send messages?

There are several reasons why mobile phones can't send text messages:

1. The status of the mobile phone card is abnormal (such as arrears), so it is impossible to send short messages;

2. The SMS in the mobile phone outbox is full. Suggest deleting the short message in the mobile phone outbox and try again.

3. SMS function is not enabled on the mobile phone card. It is suggested that you call the Unicom customer service hotline 100 10 to check whether the SMS function of the mobile phone card is opened normally; The SMS center number is incorrect. You can reset the SMS center number in your mobile phone. The number of SMS centers in every province and city is the same. For example, the number of Tianjin Unicom's SMS center is+8613010130500.

If you are a Unicom mobile phone user in other provinces and cities, you can call the Unicom customer service hotline 100 10 where your mobile phone card belongs.
