Activating your USRobotics Cellular Modem
To start using the USR3500 USRobotics Courier® M2M 3G GSM Intelligent Cellular Modem you will need to acquire a SIM and wireless data services from a Mobile Virtual Network Operator (MVNO) or Mobile Network Operator (MNO).
Where do I get SIMs and a data package?
USRobotics' preferred partner offers exclusive data rate packages for USRobotics customers that allow SIM quantity flexibility, static IPs, Internet Tunnels, VPNs, as well as expansive reach with coverage around the world.
USRobotics recommends Telit m2mAIR Mobile for both enterprise as well as small and medium businesses. Many MVNOs do not allow accounts with small volumes, but with USR's partnership Telit m2mAIR Mobile will support accounts of all sizes.
What about retail SIMs? Retail SIMs are readily available but are designed for consumer use and may not include features required for business use. There are some features to take into consideration: data pooling, static IP, and security. Most retail carriers do not offer data pooling, but MVNO subscribers can aggregate data across their account and therefore can utilize smaller, less expensive data plans while still having access to larger amounts of overall data. Many M2M solutions such as remote management and out of band remote diagnostics are mobile terminated and may require a static IP, which may not be available from most retail carriers. Finally, security is very important and requires Internet Tunnels and in some cases additional encryption levels on a VPN, which are not available from retail carriers.
To learn more about our data rate plans and services or to sign up for services with Telit m2mAIR Mobile and receive USR's special rates, just give USRobotics Client Services a call at 1 (866) 944-3861 and they will help you weed through all the details and assist with the process of getting service.
Already have a wireless provider?
For customers that may require different solutions or may already have a partnership in place, the USR modem can easily be set to work with any GSM based network by changing the APN as described below.
Basic Steps for activation and installation:
Changing the APN/IP on the USR3500
Enter AT+WOPEN=1 to start the Courier M2M application. A startup banner will display. Use AT+WOPEN=0 to stop the application.
Lib Version 1.9.1
To use IP data services, you need to configure an APN. Your cellular account needs to have data services, and the cellular provider must provide you with an APN string. * For this example "m2m.apn.com" will be used, replace this with the string provided by your cellular provider.
Enter AT$CGDCONT=1,m2m.apn.com to set the APN.
Use AT+CGREG? to verify GPRS registration.
A response with 0,1 indicates that your device is registered on the GPRS network. A response of 0,0 would indicate not registered. Once you are registered, Courier M2M will automatically activate a PDP context. Enter AT$IP to verify the device’s IP address.
