Connecting to Your Cellular Provider
The ICX35-HWC supports 3G GSM/GPRS and 4G LTE (where applicable) networks.
It uses your cellular provider as an ISP (Internet Service Provider) to connect to the
Internet. All cellular service connections require a Subscriber Identity Module (SIM) to
be installed in the ICX35-HWC. This includes connections to CDMA based services
like Verizon (previously did not require a SIM). Contact your service provider to
obtain a SIM.
2.3.1
Connection Using GSM/GPRS
The Subscriber Identity Module (SIM) in the ICX35-HWC is a smartcard that securely
stores the key identifying a cellular subscriber. Generally, you will only need to install
a SIM once in the life of the cellular gateway - and it may be pre-installed by your
ProSoft Technology Representative.
Important: Your cellular provider must provide the Public APN and IP address of the SIM card.
AT&T Users:
For SMS texting functionality, you must power up the ICX35-HWC with
the SIM installed within 72 hours after AT&T activates the SIM card.
The SIM card slot is located on the front of the cellular gateway.
