Ios mobile coverage is good but not excellent. That means your mobile phone is going to spend more energy trying to connect to the network, thus running your battery dead sooner. Take with you a spare battery or keep in mind you have to recharge your battery regularly :-)
You can find a doctor on Ios as well as pharmachies but you wont be able to buy a new pair of contact lences or a cleaning solution system. Keep in hand
spares just in case something goes wrong and always remember that exotic cosmetics and perfumes are difficult to find :-)
Keep your eyes open when guying food. Prices on fruits, softdrinks, juices and alcohol vary. You might buy beers cheaper to one place and fruits cheapper to another place.
