US Mobile Data and eSIM Guide for Dutch Travelers: Staying Connected

Dutch travelers heading to the United States often ask whether their mobile phone will work abroad. The short answer is: yes, but not without extra charges. EU roaming regulations do not cover the US, which means using your Dutch SIM card in America can cost you significantly. This guide covers all the options — eSIMs, Dutch provider add-ons, and prepaid US SIM cards — so you can stay connected without breaking the bank.

Why Dutch Mobile Plans Don't Work in the US

The European Union's "Roam Like at Home" regulations ensure that Dutch mobile plans work seamlessly across EU countries without extra charges. However, the United States is not part of the EU, so these rules don't apply. When you land in the US, your Dutch provider will charge you roaming rates that can quickly add up — sometimes €5-10 per MB of data.

While all three major Dutch providers (KPN, Vodafone, T-Mobile NL) offer international roaming in the US, their standard pay-as-you-go rates are expensive. The good news is there are several affordable alternatives, from dedicated travel eSIMs to Dutch provider travel add-ons.

Best eSIM Options for Dutch Travelers in the US

An eSIM (embedded SIM) is a digital SIM that lets you activate a mobile plan without a physical SIM card. Most modern smartphones — iPhones from XR onwards, Google Pixel, and Samsung Galaxy flagships — support eSIM. This is often the cheapest and most convenient option for Dutch travelers.

Airalo

Airalo is the most popular eSIM provider for international travel. For the US, they offer regional and country-specific plans:

• 1 GB for 7 days — approximately $4.50
• 3 GB for 30 days — approximately $11.00
• 5 GB for 30 days — approximately $16.00
• 10 GB for 30 days — approximately $26.00
• Unlimited data plans also available for heavy users

Airalo uses the T-Mobile and AT&T networks in the US, providing reliable 4G/LTE coverage in most urban and suburban areas. Installation takes about 5 minutes via their iOS or Android app.

Holafly

Holafly specializes in unlimited data eSIMs for travelers. Their US eSIM plans include:

• 5 days unlimited data — approximately $19.00
• 10 days unlimited data — approximately $34.00
• 15 days unlimited data — approximately $47.00
• 20 days unlimited data — approximately $54.00
• 30 days unlimited data — approximately $69.00

Note: Holafly plans are data-only — they do not include a US phone number for calls or SMS. If you need a local number, Airalo or a prepaid SIM might be better.

Maya Mobile

Maya Mobile offers US eSIM plans with data and optional US phone numbers:

• 3 GB for 15 days — approximately $12.00
• 7 GB for 30 days — approximately $22.00
• 15 GB for 30 days — approximately $36.00
• Includes a US phone number with some plans

Dutch Provider US Add-Ons

All three major Dutch mobile providers offer special travel bundles for the US. These are convenient because you keep your Dutch number on the same SIM.

KPN Travel Bundle

KPN offers a US travel bundle that includes:

• 1 GB data for €9.95 (valid 30 days)
• 3 GB data for €14.95 (valid 30 days)
• 5 GB data for €19.95 (valid 30 days)
• Unlimited calls and SMS included with all bundles

KPN uses the AT&T network in the US. You can activate the bundle via the KPN app or by sending a text message.

Vodafone NL Travel Bundle

Vodafone's Travel Data Bundles for the US:

• 1 GB for €10.00 (valid 30 days)
• 4 GB for €15.00 (valid 30 days)
• 8 GB for €20.00 (valid 30 days)
• Includes unlimited calls and SMS back to the Netherlands

Vodafone uses the Verizon network and T-Mobile US for coverage. You can purchase through the My Vodafone app.

T-Mobile NL Travel Bundle

T-Mobile NL offers Data Bundles for the US:

• 1 GB for €10.00 (valid 14 days)
• 3 GB for €15.00 (valid 30 days)
• 6 GB for €25.00 (valid 30 days)

Note: T-Mobile NL customers on certain subscriptions also get free 1 GB of data per month in the US as part of their plan. Check your subscription before buying an extra bundle.

Prepaid US SIM Cards

If your phone is unlocked, you can buy a prepaid SIM card at US airports, electronics stores, or online. This is especially useful if your phone doesn't support eSIM.

T-Mobile US prepaid: Tourist plans starting at $30 for 10 GB of data with unlimited texting, valid for 30 days. Available at T-Mobile stores, airports, and online.

AT&T prepaid: $30 for 5 GB of data valid for 30 days, or $40 for 15 GB. Available at AT&T stores, Walmart, Target, and airport kiosks.

Mint Mobile: Budget option using T-Mobile's network. $15/month for 5 GB when buying a 3-month plan. Requires online activation, so order before you travel.

eSIM vs Dutch Roaming vs Prepaid SIM: Which Is Best?

Here's a quick comparison to help you decide:

• eSIM (Airalo/Holafly) — Cheapest, most convenient, instant activation. Best for short trips and modern phones. Data-only on most plans.
• Dutch provider add-on — Slightly more expensive but keeps your Dutch number. Best if you need to receive calls/SMS on your Dutch number.
• Prepaid US SIM — Good for long stays or if you need a US phone number. Requires an unlocked phone and slightly more effort to set up.

How to Set Up an eSIM Before Your Trip

Setting up an eSIM before you leave the Netherlands is straightforward:

1. Check if your phone supports eSIM (Settings > Mobile Data > Add eSIM on iPhone; Settings > Network & Internet > SIMs on Android).
2. Download the eSIM provider's app (Airalo, Holafly, or Maya Mobile) from the App Store or Google Play.
3. Purchase a US data plan within the app — prices range from $4-20 for most short trips.
4. Follow the in-app instructions to install the eSIM profile. This usually involves scanning a QR code or installing a profile automatically.
5. When you arrive in the US, enable the eSIM line and disable your Dutch SIM's data roaming. The eSIM will connect to a US network automatically.

Tip: Install the eSIM profile before you leave the Netherlands so you have a stable WiFi connection during setup. Most eSIMs activate only when they detect a US network anyway.

Cost Comparison: What Will You Actually Pay?

For a typical 10-day trip to the US, here's what you can expect to pay for mobile data:

• Airalo 5 GB plan — ~€15 (best value for moderate users)
• Holafly 10 days unlimited — ~€31 (best for heavy users who need lots of data)
• KPN Travel Bundle 1 GB — €9.95 (convenient but expensive per GB)
• T-Mobile NL free 1 GB — €0 if included in your subscription
• AT&T prepaid 5 GB — ~€28 (good if you need a US number)
• Standard roaming (no bundle) — €5-10 per MB (avoid at all costs)

For most travelers, a €15-20 eSIM plan from Airalo or Holafly provides the best balance of cost, convenience, and coverage.

Tips for Staying Connected in the US

• Download offline maps (Google Maps allows this) before you leave to save data.
• WhatsApp and FaceTime work perfectly over data-only eSIMs — no US phone number needed.
• Public WiFi is widely available in the US but may not be secure. Use a VPN for sensitive transactions.
• Airport WiFi at major hubs (JFK, Newark, LAX) is usually free and fast enough for basic browsing while you set up your eSIM.
• If you have a Dutch KPN or T-Mobile subscription that includes free US data (1 GB/month), enable it as your primary data line and turn off data roaming on your other lines.
• Dual SIM users: keep your Dutch SIM active for calls/SMS (with data roaming OFF) and use the eSIM for all data traffic.

Frequently Asked Questions

Can I use my Dutch phone plan in the US without extra charges?

Not by default. EU 'Roam Like at Home' rules don't cover the US. Standard roaming rates apply — typically €1-2 per minute for calls and €5-10 per MB of data. Always buy a travel bundle or eSIM before you go.

What is the cheapest way to get mobile data in the US?

An eSIM from Airalo is generally the cheapest option for short trips. A 1 GB plan costs around $4.50 and covers most basic needs (maps, messaging, emails) for a few days. For longer stays, Holafly's unlimited plans or prepaid US SIMs offer better value.

Do I need a US phone number?

Not necessarily. Most Dutch travelers use WhatsApp, iMessage, or FaceTime for communication, which work over data-only connections. You only need a US phone number if you plan to make local calls to US numbers (restaurants, hotels, Uber drivers) or if your bank requires SMS verification.

Will WhatsApp still work in the US?

Yes, WhatsApp works over any internet connection. As long as you have data (via eSIM, roaming bundle, or WiFi), WhatsApp calling and messaging will work exactly as they do in the Netherlands.

Can I buy a SIM card at a US airport?

Yes, most major US airports have kiosks or stores selling prepaid SIM cards from T-Mobile, AT&T, and Verizon. However, airport SIMs tend to be more expensive than buying from a store in the city or ordering online beforehand. If you have eSIM support, it's usually a better option.

Will my Dutch credit card work for mobile plans?

Yes, all major eSIM providers (Airalo, Holafly, Maya Mobile) accept international credit cards and PayPal. Dutch Maestro cards may not work on US websites — use a credit card or a virtual Revolut/Mastercard instead.

What if my phone doesn't support eSIM?

If your phone doesn't support eSIM, your best options are: (1) buy a travel bundle from your Dutch provider (KPN, Vodafone, or T-Mobile NL) before you leave, or (2) buy a prepaid US SIM card at a US electronics store like Best Buy, Target, or Walmart after you arrive.

The Bottom Line

Staying connected in the US as a Dutch traveler doesn't have to be expensive or complicated. For most travelers, an eSIM from Airalo or Holafly is the easiest and most affordable option — you set it up before you leave and it activates automatically when you land. If you need to keep your Dutch number, a travel bundle from KPN, Vodafone, or T-Mobile NL costs slightly more but offers convenience.

Whatever option you choose, plan ahead. Download your eSIM or buy your travel bundle before departure so you're connected from the moment you land. And never use standard pay-as-you-go roaming — it's by far the most expensive way to use your phone in the US.
