How to send AT commands on MikroTik LTE modems

On MikroTik routers with an LTE modem, you can send arbitrary AT commands to the modem using the terminal’s at-chat feature.

Login to the router terminal using a browser or SSH.

One-shot AT command

You can send a single AT command directly using /interface lte at-chat with the input parameter:

[admin@Lauingerstr-55] > /interface lte at-chat lte1 input="AT+CNUM"
  output: +CNUM: "","+49176123456789",145
          OK

Replace lte1 with the name of your LTE interface (check /interface lte print if unsure).

Interactive AT chat

You can also enter an interactive chat session where you can type multiple commands:

[admin@Lauingerstr-55] > /interface lte at-chat lte1
input: AT+CPIN?
  output: +CPIN: READY
          OK

Type your AT command at the input: prompt and press Enter.

Useful AT commands

• AT+CPIN? - Check SIM PIN status
• AT+CNUM - Query your own phone number (see How to find your own LTE phone number on MikroTik using AT commands)
• AT+CSQ - Query signal quality
• ATI - Show modem identification info

Note that the exact set of supported AT commands depends on the specific LTE modem module in your router.
