How to set up Mikrtotik SXT LTE Kit with a SIM card as a backup communication channel for the main Hex S router?

Question

Mikrotik

I got into a dead end, I don’t understand what could be the matter, the LTE functionality is written completely, the status is OK, it receives ips from Iota via DHCP, but the pings do not go through the Internet. Firewall is off, nat masquerading on the LTE interface is added.
Has anyone configured SXT not as a router?

Answer 1

Stupid clarifying question - how is the route configured? Ping fails on iot's ip? No internet on SXT? I have several such toys in my work, and it is with Iota's sim cards with statistics that they start up automatically with a bang. True, I always delete the default config.
