Haarlem eSIM.
From the Grote Markt to Teylers Museum, explore Haarlem's golden-age streets fully connected.
Haarlem eSIM plans: unlimited, or by the GB.
Every Haarlem eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Haarlem — you can always top up or switch on your next trip.
Unlimited plansHigh-speed data, nothing to count
Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.
- Best for streaming, video calls & hotspot
- Great for longer or open-ended trips
- One price per day — no GB anxiety
A set bundle, brilliant value
A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.
- Best value for lighter, shorter trips
- Clear allowance — pay only for what you need
- Top up any time from your phone
How much data do you need in Haarlem?
A rough, honest guide to sizing your Haarlem eSIM so you're not guessing. Most travellers in Haarlem are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.
Google Maps, WhatsApp, email and the odd search. Plenty for a city break where you mostly need directions.
Everything above plus social scrolling, music, cloud photo backups and a little video. Where most travellers land.
Netflix by the pool, long video calls home and hotspot for the laptop — go Unlimited and stop counting.
Haarlem eSIM: your local data guide.
Just fifteen minutes from Amsterdam, Haarlem offers the same canal-and-gable beauty with fewer crowds, centred on the Grote Markt and its towering St Bavo church. A Haarlem eSIM lets you book Frans Hals Museum tickets, hunt down the hidden hofjes courtyards, and check the train time to Zandvoort beach whenever the sun appears.
Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.
Where you'll lean on data in Haarlem.
On the main square beneath St Bavo, book a church visit, pick a café terrace and read the market-day schedule.
At the oldest museum in the Netherlands, use data to reserve entry and translate the cabinets of fossils and instruments.
Hunt down Haarlem's peaceful almshouse courtyards with maps, since many hide behind unmarked doors along the old lanes.
Along the river by the reconstructed windmill, navigate the waterside walk and share photos of the classic Haarlem skyline.
Getting around Haarlem on your eSIM.
- Connexxion— Haarlem and Kennemerland's bus operator, plus Schiphol links; tickets and live times in-app.
- NS— Frequent trains to Amsterdam and Schiphol — live platforms and e-tickets in-app.

Haarlem is often a day trip or overnight from Amsterdam, covering the Grote Markt, the Frans Hals Museum and a short train hop to Zandvoort beach.
A day out or overnight sits easily on 1-2 GB for maps, train tickets and photos; step up to 3-5 GB if you're basing yourself here and day-tripping into Amsterdam.
5G covers the centre, the Grote Markt and the station well, and reaches out toward Zandvoort and the coast; the dunes and quieter beach stretches are where the signal realistically thins.

Your Haarlem eSIM: data-only, zero bill shock.
Your Haarlem eSIM handles the internet while you travel. Your home number stays exactly where it is — no surprise roaming charges in Haarlem, no swapping your real SIM out.
The eSIM is data-only and runs alongside your home SIM. Your number, iMessage and WhatsApp keep working exactly as they do at home.
Turn data roaming OFF on your home SIM and ON for the eSIM. You pay once, up front — no overage, no metered surprises, no bill waiting when you land home.
Because it's data-only, the eSIM can't receive bank verification (OTP) text codes — those still go to your home number. Keep it reachable on Wi-Fi calling, or use app-based codes.
