Yes but it does not always work well especially outside where you wait for taxis. I do believe when you exit the airport you can connect to the Grouvy Grouper Bar's wifi, or at least I have in the past when I sat and had a beer there. The bartender gave me the password on those occasions but I haven't done it in a couple of years. If you're just worried about calling your taxi there are plenty of people around who will let you use their phone for a couple of bucks too.
