Your service provider will charge you for your data usage. Please check with your provider to make sure
you are aware of the charges.
Your MultiModem iSMS can be used to send a large number of SMS messages very quickly, and, as such,
you should have a contract/plan that accounts for the numbers of messages you are likely to send. Multi-
Tech is not responsible for any charges relating to your cellular bill.

troubleshooting your connection. To do this, open a Telnet connection to the MultiModem iSMS,
specifying port 5000. This will provide AT command line access to the first GPRS modem in the
MultiModem iSMS. Use the AT commands* to determine cellular connection status.
