You just estimate it the best you can. You'll very rarely be able to know exactly what your opponent's range is with 100% certainty, and that's okay. With total unknowns, you can use certain clues like what their buy-in size was and what the typical players are like at that level. With semi-unknowns, you take whatever small bits of information you have and try to extrapolate.

In general just do the best you can each time and you'll naturally get better at it, even with very small amounts of information.
