trust me when i say i will never see a computer recycling center where i live, if someone considers a computer to be too old to use here, it ends up in normal trash, i've rescued some of off there, but i cant bring every single one home, and it needs to really be considered old to be there, good rule of thumb is 15 years old is unlikely, and 20+ is the most common, there are however a few usb modems, and some even work as wifi modems, though for some reason, movistar and antel (the two biggest phone companies, the third and only other, claro, is mostly to give coverage to tourtists) will not sell them through their online store, only physical stands, they are also surprisingly not by unknown brands, i remember a huawei usb one, as well as huawei and alcatel for the wifi capable ones, sure, they are not the most trustable brands in the world, but they arent things like genius or kolke
