A major benefit of GSM technology is its support of short messages 

(SMS) for easy communication over the mobile network. With MOXA’s 

SMS Tunnel Mode, applications can be expanded and extra costs 

eliminated. For example, SMS Tunnel Mode can be used to update the 

message on a highway display panel, place refill orders for vending 

machines, handle maintenance for remote rental equipment, or even 

help to create the SMS alarm by directly transforming the text, binary 

or unicode data from a legacy device to short messages without AT 

Commands. It is particularly suitable for devices which communicate 

infrequently or lack access to the local network. Although SMS 

Tunnel Mode converts both ASCII and binary data to short messages 

transparently back and forth, design of the Caller ID(phone number) 

Identification has been implemented to block the message sent from 

the uncertified users, system broadcast and those commercial SMS 

advertisement.   

For security purposes, the SIM card is installed within the OnCell 

G2150I housing. The outer cover must be unscrewed and removed for 

access to the SIM card slot. Moreover, if an OnCell G2150I is installed 

on a DIN-Rail or a wall, SIM Cover is not able to be opened from its 

housing easeily before removing it from the DIN-Rail.. 

Once the correct PIN is entered with the AT+ CPIN command, or using 

OnCell Configurator, the system (firmware V1.2 or above) will activate 

the Automatic PIN Entry function. This function will store the current 

PIN in its memory and enter it into the OnCell G2150I each time the 

system boots up. If the SIM card does not match the current PIN, the 

Automatic PIN Entry function will be deactivated.

OnCell Configurator is a PC-based software tool for managing and 

configuring OnCell G2150I modems. With a full graphics mode and 

Windows-based environment, even first time users will find it easy 

to learn how to use this new tool. OnCell Configurator can be used 

to configure the general phone settings and modes for auto dial-out 

parameters, but without the need to look up AT commands.
