There are tiers, basic one won't get you much. You will have to keep (I think 50kish) a certain amount to have the higher tier which comes with unlimited no forex spends. Works good as you can always take the money out after your travel.
Otherwise, get Scapia. It's a CC, most likely you should get it. No forex, but you won't be able to withdraw cash. It's issued by Federal bank, just like Fi, will work fine.
