Nah it's that size. You need an individual modem for each SIM card because you need a unique IMEI. It's possible each of those SIMs are eUICCs as well which means basically that each card is like a "wallet" with multiple profiles.
I've used hardware a decent amount larger than what's pictured in the OP for work. But what I was using wasn't just for SMS. So I needed more sophisticated modems. What they're using looks like a bunch of 64 port modem banks exclusively for SMS.
(Oh wait if you mean the devices for what's in the article you linked, then yea, those I'm sure are much smaller and quite different.)
The modems don’t support on-the-fly IMEI programming? Even if not, I could see the same RF components share a number of whatever the bare minimum chip is for an IMEI and switch
