"Only one mobile phone card or Internet of Things card is needed to enable the device to have information transmission functions such as GPRS/GPS/ SMS/voice call. "
If you are using a SIM card, it depends on the type of SIM card you have.
Quad-band GSM/GPRS (850/900/1800/1900MHz)
You can refer to the sample program for common functions of calling and sending text messages.
