  If the results are unsatisfactory on all configured servers, the active SIM card will switch. If the results are successful on at least one of the specified servers, the switch will not occur. For the mechanism to work, be sure to add at least one ping-server to the configuration;

• MAX RTT, ms – maximum average response time for all sent ICMP requests. If this value is exceeded, the active SIM card will switch, or go to the next ping-server;
• MAX Jitter, ms – maximum deviation from the average response time. If this loss value is exceeded, the active SIM card will switch, or go to the next ping-server.
