Getting a Dutch Phone Number and Mobile Plan for US Citizens
A Dutch phone number is one of the first things you'll need after moving to the Netherlands under the Dutch-American Friendship Treaty (DAFT). Not eventually. Immediately.
WhatsApp runs on phone numbers, and WhatsApp is how the Netherlands communicates. Landlords, doctors, government offices, new friends -- everyone uses it. Without a Dutch number, you're cut off from the main way people connect here.
Here's how to get set up, what it costs, and how to handle your US number.
Option 1: Prepaid SIM (Get This First)
Buy a prepaid SIM card the day you arrive. You can grab one at Schiphol airport or at phone shops in any city center. No BSN, no bank account, no contract -- just pay cash or card and you're connected.
Best prepaid options:
Lebara -- Popular with expats. Cheap international calling rates to the US. Available at supermarkets, phone shops, and the airport. Plans start around 10-15 euros per month for calls, texts, and a few GB of data.
Lycamobile -- Similar to Lebara. Good international rates, easy to find, no commitment. About the same pricing.
Simyo -- A Dutch provider with straightforward prepaid plans. Slightly better network coverage since it runs on KPN's network.
What you get: A Dutch +31 phone number, data, calls, and texts. Enough to set up WhatsApp, make appointments, and function while you sort out the rest of your life.
Pro Tip: Buy two prepaid SIMs from different providers. Data speeds and coverage vary by location in the Netherlands. Having a backup means you're never stuck without service during an important first week.
Option 2: Contract Plan (Set Up in Week 2-3)
Once you have your BSN and Dutch bank account, you can get a proper contract plan. Contract plans offer more data, better prices long-term, and often include a phone if you need one.
Requirements for a contract plan:
- BSN (burgerservicenummer)
- Dutch bank account with IBAN
- Proof of address
- Valid ID (passport works)
Major Dutch providers:
KPN -- The biggest Dutch carrier. Best coverage nationwide, including rural areas. Most expensive, but reliable. Plans start around 20-25 euros per month for unlimited calls/texts and 10+ GB of data.
T-Mobile NL -- Good coverage, competitive pricing. Often has deals for new customers. Similar pricing to KPN with occasional promotions.
Vodafone NL -- Third major carrier. Good coverage in cities, slightly spottier in rural areas. Comparable pricing.
Budget options (MVNOs):
Ben -- Runs on T-Mobile's network. Cheaper plans starting around 10-15 euros per month. No-frills but solid.
Simyo -- Runs on KPN's network. Good budget choice with flexible plans.
Hollandsnieuwe -- Very affordable. Plans as low as 7 euros per month. Limited customer service but the basics work fine.
What We Use
We went with KPN on a 2-year contract. It's not the cheapest, but the coverage is excellent everywhere in the Netherlands, and the apps work smoothly. We pay about 25 euros per month each for unlimited calls, unlimited texts, and 20 GB of data.
What We Wish We Knew: Contract plans in the Netherlands typically have a cancellation notice period of one month. Unlike US contracts that lock you in for years with penalties, Dutch contracts are relatively flexible after the initial term. But read the fine print before signing.
What About Your US Number?
Don't cancel your US phone plan yet. You'll need your US number for:
- Two-factor authentication on US bank accounts
- Receiving calls from US businesses and government agencies
- Keeping in touch with family who don't use WhatsApp
- Logging into US-based services that require phone verification
Your options for keeping your US number:
Google Voice -- Port your US number to Google Voice for a one-time fee of about 20 dollars. You can receive calls and texts over WiFi or data. This is what most Americans in the Netherlands do, and it's what we did.
T-Mobile or Google Fi -- Some US plans work internationally. T-Mobile's international plans include basic data and texting abroad. Google Fi works in the Netherlands with no extra fees. But both are more expensive monthly than porting to Google Voice.
Number parking services -- Services like NumberBarn or Tossable Digits will hold your US number for a few dollars per month and forward calls or texts.
Reality Check: Google Voice has limitations. It doesn't work for all two-factor authentication systems (some services block VoIP numbers). Before porting, test that your critical accounts accept Google Voice for verification. We had to keep a cheap US prepaid line for two stubborn accounts.

eSIM vs. Physical SIM
If your phone supports eSIM (most recent iPhones and Android flagships do), you can run two numbers on one phone -- your Dutch number as the primary and your US number as the secondary.
How it works:
- Dutch SIM goes in the physical slot (or as an eSIM)
- US number lives on Google Voice or a secondary eSIM
- You choose which number to use for calls, texts, and data
This is the cleanest setup. One phone, two numbers, no second device.
If your phone doesn't support eSIM, you'll need to swap SIM cards or carry a second phone. An old phone works fine for this -- it just needs to connect to WiFi for Google Voice.
Setting Up Utilities and Services
Once you have a Dutch phone number, you can:
- Set up WhatsApp with your Dutch number
- Register for DigiD (digital government identity)
- Make appointments at the gemeente
- Sign up for Dutch services that require phone verification
- Get added to neighborhood WhatsApp groups
Many of these require an active Dutch number for SMS verification. This is why getting a SIM card on day one matters -- it unblocks a cascade of other setup tasks.
Quick Setup Checklist
Day 1: Buy a prepaid SIM at the airport or a phone shop. Set up WhatsApp.
Week 1-2: Port your US number to Google Voice (do this while you still have your US SIM active -- the port takes 24-48 hours).
Week 2-3: Once you have your BSN and Dutch bank account, sign up for a contract plan if you want one. You can keep the same prepaid number or get a new one.
Month 1: Set up DigiD using your Dutch phone number. Test that all your important US accounts work with your Google Voice number.
The whole process costs very little -- maybe 10-20 euros for your first prepaid SIM and 20-30 euros per month for a contract plan. Compared to what most Americans pay for phone service back home, you'll likely save money.
