GSM offers a wider coverage area, mobility and data rates which are desired features for distant IOT devices on the move. Power consumption of GSM IOT devices is higher and a continuous power source is needed in most applications. A battery power IOT device can last for days and not years as is the case for LoRa and SigFox technologies. GSM based IOT needs a SIM card which means sending large amount of data can be costly.
As with all SM01 modules, SM01-GSM module has identical microcontroller, hardware add-ons, expansion connector, and provided with appropriate software libraries which enables application code migration seamless across all SM01 series.
