Phone, Post & Internet


Mobile Calling

When in Holland, you may use the Dutch network with your own mobile telephone. The costs for mobile telephone calls depend on your own service provider. You can also buy a prepaid phone card. These cards are available at various prices at supermarkets, post offices, gas stations, tobacconists and phone shops.

Holland has numerous places where you can use a computer with internet access, including internet cafés, libraries and almost any hotel. Nowadays many restaurants, lunch rooms, coffee shops and cafes also offer free WiFi services.  

Post Offices

Most post offices are open from Monday to Friday between 9 a.m. and 5 p.m. Only the major post offices are open on Saturdays. Services offered by the post office include sending letters and packages, buying stamps, postcards, stationery, telephone cards and public transport cards, and withdrawing cash from an ATM.

International mail may be deposited in any mailbox, provided the item weighs less than two kilograms. If the parcel weighs more, you will have to send it from a post office.
