iphone telecom card calls normal text messages

Hello, you would like to ask if it is not possible to send text messages during normal phone calls using the iPhone telecom card. The SMS function is not enabled.

Normal mobile phones have original factory settings and can communicate with normal functions as long as there is no payment arrears. However, if the restricted functions in the mobile phone are artificially set, text messages cannot be sent. Therefore, if there are some obstacles in the functions of the mobile phone, it is convenient to first open the settings and check whether it is normal.
