MikroTik RouterOS:
Nếu đổi tên interface lte rồi thì thay cái lte1 đi nè ^^
/interface lte at-chat lte1 input="AT!OPENLOCK=\"code\""
/interface lte at-chat lte1 input="AT!NVIMEIUNLOCK"
/interface lte at-chat lte1 input="AT!NVENCRYPTIMEI=12,34,56,78,90,12,34,70"
/interface lte at-chat lte1 input="AT!RESET"

OpenWrt:
opkg update
opkg install socat
echo "AT!OPENLOCK=\"code\"" | socat - /dev/ttyUSB2,crnl
echo "AT!NVIMEIUNLOCK" | socat - /dev/ttyUSB2,crnl
echo "AT!NVENCRYPTIMEI=12,34,56,78,90,12,34,70" | socat - /dev/ttyUSB2,crnl
echo "AT!RESET" | socat - /dev/ttyUSB2,crnl
