There are no WAAS ground stations in this part of the world so it can't be working. You may think that it is working but in fact it isn't, you are simply receiving an uncorrected GPS signal. WAAS satellite coverage plus ground stations are only available in North America. I am surprised that you as pilot can be so ignorant in this regard.
Western Europe has it now as well. LPV approaches are well under way.
