Also, last time I went to the stadium, purchases inside were cash-only, and taxis generally need to be paid by cash (although maybe 25% of those from Pink and Naxis, and slightly more from Lux, have card machines).I'd say it's accepted in 80-90% of places you'll go, but definitely bring cash. 1. Tips can't be paid by card, and 2. (If buying a sim) phone credit can't be bought by card (for some strange reason I've never been able to fathom). Also, I don't think you'd be able to buy a ticket for the EDS game by card (if you need to - see my post above), but I can't be sure about that.
