With SMS, you can send real-time alerts to your technicians, warning them of potential service outages or any other danger to reliable up-time. If your site doesn't currently have a mode of communication, or simply needs a mode of backup communication, the NetGuardian 216 SMS is an affordable option for monitoring remote sites.

The NetGuardian 216 SMS supports both CDMA and GSM, allowing you to bring your own SIM card with a real phone number and get notified of alarms right away. Paired with the SMS Receiver, you can send your SNMP Traps to your master station. The SMS Receiver is a flexible device that can accept both CDMA and GSM connections natively.

If you're looking for a backup communication method in case of LAN failure, the NetGuardian 216 SMS can switch to use SMS from LAN and is a great addition to your network monitoring system. With this intelligent switching, you also don't have to worry about duplicate or nuisance alarms. It's an effective way to stay in the know of what's going on at your remote sites.
