I've been looking for something like this, but with a built in LTE modem.
Also, where do you buy (IoT?) Sim cards cheaply, valid over entire continents or worldwide?

Looks like they are coming: https://www.gl-inet.com/products/gl-rm10c4/?utm_source=websi...
get a esim adapter (ie. euicc in sim card format), find a plan on https://esimdb.com/, load it onto the esim, and plug it into your iot device.
They don't seem to offer/list Lyca cards, which are among the cheapest, in my (limited) experience.
