Below quote is the configuration Guide on the Bi-directional forwarding, here when the latency of the ISP has reach above 1000ms during the 50 sample it will then give a command to switch over to other SIM card. The ip on the feature nsm echo is the IP that which the router always try to reach and determine the latency for 50 samples.
