QuoteI powered the module but I'm not sure if it works. How can I determine that it works?To turn on the unit you would need need to press and hold the PWRKEY for a few seconds. The green LED should turn on and start blinking rapidly. The green LED also indicates the status of the communication with the GSM network - after the initial few seconds it begins to blink at a much slower pace - this means that the communication with the GSM network is ok; alternatively if the LED stops blinking - there is a problem with the network (most likely improper network settings).
