A single modem or carrier outage should not stop your messaging. Modem Failover keeps a backup ready, so one failure never takes your SMS delivery down.
Choose whether messages are sent from each modem in turn (round-robin) or always from one main modem, with the others waiting as backup.
Failover covers both a failed modem and a carrier network outage, whichever causes the disruption.
Alongside failover, SMSEagle spreads load across modems with round-robin selection, plus message routing and queuing for reliable delivery.
Every modem, one view
Check the status of every modem on your device at a glance, so you always know which one is carrying your traffic.
Control how modems are chosen
In the modem settings, choose Round-robin, or set one SIM card as the main modem.
Just turn on one option
Turn on failover so a backup modem takes over automatically whenever the primary one has a problem.
SMSEagle hardware SMS gateway
SMSEagle combines hardware and software into a single, self-contained gateway. It is designed for critical environments, so security is built in from the ground up, confirmed by CE, FCC, ISED, UKCA, PTCRB, RCM, IMDA, TDRA, CB Scheme, GCF, carrier certifications (Verizon, AT&T) and ISO 27001.
SMSEagle regularly checks that each modem is connected to the network and able to send. If a modem stops working, messages are sent through the next modem, so sending continues.
