Mikrotik KNOT (RB924i-2nD-BT5&BG77). I tried on RouterOS 6.48.3, 6.49beta54, 7.1beta6.
The LTE interface doesn't work, it's not listed as an interface. There is a ppp-out1 interface (Type: PPP Client).
I tried it with Megafon SIM card, "Smart Stuff" tariff, and with Beeline SIM card. The SIM cards are functional, they work in the phones.
I also tried switching "direct IP mode", KNOT did not switch to LTE mode. I also switched MPCIe: /system routerboard usb set type=mini-PCIe, did not help too.
What is the procedure to use LTE on KNOT?
