If you want to use the SMS function of Modem, you need to ensure that SMS of your GSM number(SIM card) has already been activated. The service can be applied for from GSM Service Provider(SP) to which your SIM card belongs. Besides, you need to know the SMS center number of the SP. And the cost of SMS can be consulted with the SP.

If you want the data transmission function of Modem, you need to activate data transmission service as the same. The highest GSM data transmission speed is 9.6kbit/s.
Notice: Your GSM number used for data transmission, and the number used for SMS, shouldn’t be the same one. Please consult the SP for details.

A. Plug power supply adapter into the DC outlet on Modem body.
B. Connect the data line of DB9 to DB15 COM to the COM port on Modem body.
C. Screw off the red hat of the antenna, and tighten the antenna connector up.
D. Use a nib or pin to push the button, so that the SIM slot will pop up. Put your SIM card into the slot, with the chip outwards. Put the slot back to the Modem as it be, and ensure that the SIM card is connected well with the card reader.
E. After all of these are done, plug in power source.
