industrial cellular modem such as the NM-GPRS/GSM module makes it relatively easy to prepare the product
for shipment to different parts of the world. The GSM/GPRS band of NM-GPRS/GSM module is configured to
900/1800 MHz by default.
Additional settings for each of the three modes are described in the following subsections.
GSM Operation Mode
