One of my customers has this modem working with RB751 (but this is currently EOL product).
IMHO every RouterBoard with USB port should work, e.g. RB951Ui-2HnD.
Do not expect 4G connection, only 3G (PPP client, not LTE).
You must also search Google how to set this modem to work with RouterOS.

HTH,

I wold also like to know the answer to this question I have a E3276 V2 & i would like to know if the RB433UAHL is compatible before i purchase.
