Obtaining and Activating a Wireless
Account
Before you can use the cellular feature, you must obtain a GSM wireless account with an activated SIM card
capable of sending SMS text messages through your service provider. Then activate the account by installing the
SIM into the SMSFinder. Please see the wireless account Activation Notice located on the SMSFinder CD;
follow the directions to complete the activation of your account.
Important Note About Service Provider Fees
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 SMSFinder 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.
Direct Communication to the Cellular Modem
You may want to communicate directly to the cellular modem to activate the modem, verify network
registration, and/or troubleshooting your connection. To do this:
1. Open a PC's command window by clicking the Start button and selecting Run.
2. Type CMD to open the command window. Click OK.
3. When the command window opens, type IPCONFIG.
4. Type Telnet 192.168.2.1 5000 (Note: 5000 is the port number).
See the GPRS AT Commands Reference Guide.
Using AT Commands to Check Network Registration
and Roaming Status
Use this command to verify that the cellular modem has been registered on a wireless network.
1. In the command window, type AT+CREG?
2. The modem will respond in one of the following ways:
Network Registration Verification
Value Network Registration Status
+CREG: 0,0 The modem is not registered on any network
+CREG: 0,1 The modem is registered on the home network
+CREG: 0,5 The modem is registered on a network and it is roaming
Note: If the modem indicates that it is not registered, verify the signal strength to determine if the
problem is the strength of the received signal.
