Yes, in this case your comment is fine. Any RouterBOARD device with a SIM Slot will work perfectly with 4G modems as wellI was not suggesting that 4G/LTE does not require a simcard, I am disputing the suggestion that there are simcards that are specifically made for 4G/LTE. A simcard that you got before 4G/LTE was invented will work perfectly fine in a device that supports 4G.
As such, I recommended the exact same routerboard for the exact same reason, the device has a SIM card slot.
But I can see how my comment is unclear so I've edited it in an attempt to make it less confusing.
