Why can I make a phone call but not send a text message on the Unicom card I just bought?

If Unicom card can't send SMS, it is recommended to check whether the SMS center number of Unicom card in the mobile phone has been modified. If the SMS center number is not the local SMS center number, the SMS cannot be sent.

If you still can't send SMS after troubleshooting, it is suggested that you can contact local personnel to find out whether the background data of the mobile phone card leads to the inability to send SMS.
