transferred over GSM network. All network devices, has unique static IP addresses. By using
APN (Access Point Name) identification your device will access an IP PDN (packet data
network), that a mobile data user wants to communicate with. In addition, to identify a PDN, an
APN may also be used to define the type of service, and access private company network. GPRS
devices cannot use dynamic addresses. Turned ON, data logger is establishing connection (if SIM
card is inserted), this takes about 30s.
