Telephones & post
Telephone booths are now rare, but you may still find them located at railway stations. Therefore, if you have a mobile telephone, you will need to check if it will function correctly here in Europe. Your mobile telephone (GSM) should have the capability to support tri-band and/or quad-band. However, this will not be the cheapest way to use your mobile telephone whilst you are in Europe. If you hope to be able to make calls inexpensively, you may need to arrange to have your SIM Card unlocked.
Of course, during your stay in the Netherlands, another way of communicating will be by post. You will notice that the orange letterboxes on street corners have two slots. Usually, the slot on the right is for local mail (check the postcode) and the slot on the left is for everywhere else in the Netherlands and the rest of the world.
