GPRS Connection

Setting up the APN
Before using GPRS connection in Windows, the APN (Access Point Name) must be added as a modem
initialization command. The following instructions explain how to set up the APN.
ATTENTION
Check the signal strength indicators on the front panel of the OnCell G2111/G2151I Series modem. If the LED
indicators are dark, then the SIM card is not installed properly, or the modem is not picking up a signal. If only
one bar lights up, the signal is not strong enough for a GPRS connection. Adjust the position of the antenna,
change the location of the installation, or use an optional high-gain antenna instead.
Make sure that your SIM card account supports GPRS service. In most regions, you will need to apply with your
mobile service provider to activate the service.
Make sure that the RS-232 port of the OnCell G2111/G2151I Series modem is connected. For the OnCell
G2151I, make sure DIP switch 1 is set to ON.
