• Network subscription to a GSM/GPRS network (you need to know what service providers are in your geographic area), and
• SIM card that has been activated by the network service provider installed on the terminal.
Capabilities
Dolphin 9500 terminals with integrated GSM/GPRS WWAN radios are optimized for the following two-way voice and data
communications:
• GSM voice data ("dial-up")
• SMS (Short Message Service) text messages
• GPRS Class 10 - data transmissions average 40-60 Kbps (wireless network carrier dependent)
SIM Card Installation

security key, contacts, etc. SIM cards can be installed and removed from compatible mobile devices, enabling you to switch
devices without losing personal and setup information. S
GSM Short for Global System for Mobile communications, GSM is an open, non-proprietary wireless WAN system
that is constantly evolving and growing. One of its great strengths is international roaming capability, which
provides standardized dialing in more than 170 countries.
