I am currently living outside the US and I can't get ahold of one of my W-2s. I would like to avoid making a call because of fees. Does anyone have any solutions?

I am currently living in South Korea. One of my W-2s was lost or never sent to me and I can't seem to access any portals that allow me to download it. The only suggestions from Turbotax are to call a number but I can't because I have an SK phone plan.
