SMS Messaging Only
When using your modem only for SMS messaging, make sure the SIM card is for GSM communication (not CDMA), configured to
send SMS messages, and that it is not locked (some SIM cards are "locked" to search for a specific IMEI number of the phone to
operate).
Note: When configured for SMS messaging only, no access to the ENVIROMUX will be possible through the modem.
For more details, see How to Setup and Test SMS Messaging
.
3G Data Transfer And SMS Messaging
To use your USB modem for 3G Data connection, your SIM card must be configured to support 3G data connections and have
either public or private IP address. Make sure the account associated with the SIM card also has SMS messaging enabled if
this feature will be used. With 3G data connection support, the ENVIROMUX can be configured (page 77) to send all alert
messaging through the USB modem instead of requiring an Ethernet connection for these messages.
Note: When configured for 3G data transfer and SMS messaging only, no access to the ENVIROMUX will be possible
through the modem.
3G Data Transfer, SMS Messaging, and Web Interface
To access the web interface through your USB modem, your SIM card must be configured to support 3G data connections and
have a public IP address. The ENVIROMUX can be configured (page 77) to send all alert messaging through the USB modem
instead of requiring an Ethernet connection for these messages. With a public IP address, you will also be able to access the web
interface using the IP address of the SIM card for full control of the ENVIROMUX through the modem.
Make sure the account associated with the SIM card also has SMS messaging enabled if this feature will be used.
Contact your service provider to obtain a SIM card with the features you desire.
SMS Relay Via SNMP
Your ENVIROMUX can be used as an SMS relay through an SNMP browser (requires firmware version 2.51 or later). SMS
messages, up to 160 characters in length, can be sent to up to 4 different phone numbers each when your SNMP browser is
properly configured. For more details, see How to Setup SNMP
.
