Power & Connectivity (SIM)

The Netherlands uses 230 volts at 50 Hz with Type C and Type F (Schuko) plugs, the same two round pins found across most of continental Europe. Devices from the UK, US or Asia usually need an adapter, and older US electronics may need a voltage converter. Most phone and laptop chargers are dual-voltage, so a simple plug adapter is enough.

Prepaid SIM cards are easy to buy from operators like KPN, Vodafone and Odido (formerly T-Mobile), plus supermarkets and phone shops. Bring an unlocked phone and, in some cases, ID for registration. As an EU market, roaming across Europe is often included, so a Dutch or EU SIM works widely. Coverage is excellent nationwide.

eSIMs are a convenient option for compatible phones. You can buy a Netherlands or Europe-wide travel eSIM online before you arrive and be connected the moment you land, with no physical card to swap. Local operators and international eSIM providers both offer data plans. Check that your phone supports eSIM and is unlocked before purchasing.

Free Wi-Fi is widely available in hotels, cafes, restaurants, libraries and many public spaces, and trains and stations often have it too. Connections are fast and reliable. For sensitive tasks on open networks, use a VPN. With cheap mobile data and strong coverage, many travellers simply rely on their SIM or eSIM.

A few apps make travel much smoother. The NS app covers national trains, while 9292 plans door-to-door journeys across all Dutch public transport. Google Maps and Citymapper work well in cities, and translation apps help with Dutch signs and menus. For getting around Amsterdam, the GVB app handles local trams, buses and metro.

The country code for the Netherlands is +31. To call abroad from a Dutch phone, dial 00 then the country code. For emergencies, 112 works from any phone. Most travellers rely on WhatsApp or other internet calling over data or Wi-Fi, which avoids call charges; an EU SIM keeps costs low if you do use the network.
