Thailand has long been a favourite destination for Dutch travellers — from backpackers exploring the islands to families escaping the Dutch winter on the beaches of Phuket. The Netherlands consistently ranks among Thailand’s leading European source markets, drawn by direct flights from Amsterdam Schiphol and a strong travel culture that spans decades.
Staying connected in Thailand is essential: Google Maps and Grab to navigate Bangkok’s streets, WhatsApp to keep family at home updated, and booking apps for the next leg of the journey. But if you leave your KPN or Odido SIM active on roaming, you will quickly find that Thailand falls firmly outside the EU — meaning the standard “Roam Like At Home” rules do not apply, and costs can spiral fast.
This guide shows exactly what KPN and Odido charge for roaming in Thailand, how a dedicated Thailand eSIM compares, and how to set everything up before your flight from Schiphol.

Why use a Thailand eSIM instead of KPN or Odido roaming?
A Thailand eSIM is a digital SIM you install on your phone before departure. It connects automatically to Thailand’s 5G networks — AIS or TrueMove H — the moment your flight lands, giving you fast, affordable data without any roaming surprises.
For Dutch travellers specifically:
- Keep your Dutch number active: Most modern phones support dual SIM. Your KPN or Odido SIM stays in your phone alongside the Thailand eSIM — set it to flight mode and use WiFi calling to receive iDEAL verification codes, calls home, and WhatsApp messages at zero extra cost.
- Enormous cost difference: KPN charges €2.50 per MB without a specific bundle. A single Google Maps session in Bangkok can cost €5–10 at that rate. A ThailandeSIM eliminates this entirely.
- More data than any KPN bundle: KPN’s best Thailand bundle gives you just 500 MB for €39.99. A ThailandeSIM gives you 35 GB — 70x more data — for €8.20.
- 5G coverage across Thailand: AIS and TrueMove H cover Bangkok, Phuket, Chiang Mai, Koh Samui, Krabi, Pattaya and all major tourist areas at 4G/5G speeds.
- Hotspot included: Share data with a travel companion at no extra charge.
eSIM vs KPN vs Odido – Thailand roaming cost comparison
Thailand is a “Voordeelland buiten de EU” (discount country outside the EU) under KPN’s classification, and Zone 3 under Odido. Neither carrier’s standard EU roaming applies. Here is a clear comparison for a 7-day trip:
| Provider | Pay-per-use rate | Best bundle option | Effective cost / 7 days | Source |
|---|---|---|---|---|
| Thailand eSIM | — | 35 GB / 7-day plan | USD $8.90 (~€8.20) | thailandesim.com, Jun 2026 |
| KPN — Bundel 500 (Voordeellanden buiten EU) | €2.50 / MB (no bundle) | 500 min/SMS/MB per month = €39.99 | €39.99 / 500 MB only | kpn.com, Jun 2026 |
| KPN — Bundel 100 (Voordeellanden buiten EU) | €2.50 / MB (no bundle) | 100 min/SMS/MB per month = €9.99 | €9.99 / 100 MB only | kpn.com, Jun 2026 |
| Odido (Zone 3) | €4.13 / MB | Internet op Reis pass (see odido.nl) | Varies — verify in Odido app | odido.nl/h3, Jun 2026 |
KPN Bundel 100 and Bundel 500 are shared pools of minutes, SMS messages, and MB of data. 100 MB is sufficient for roughly 1–2 days of very light use; 500 MB covers approximately 5–7 days of basic messaging and maps only — no streaming or video calls. Odido €4.13/MB rate applies without an Internet op Reis pass; always activate a pass before travelling. USD/EUR rate: ~0.92, June 2026.
The numbers tell a clear story. KPN’s best bundle for Thailand gives you just 500 MB for €39.99. A ThailandeSIM gives you 35,000 MB (35 GB) for €8.20 — that is 70 times more data at one-fifth of the price. Even KPN’s cheaper €9.99 bundle, which gives you only 100 MB, is barely worth activating.
Bottom line: For any trip to Thailand of 3 days or more, a ThailandeSIM at ~€8.20 (USD $8.90) for 35 GB is cheaper, faster, and delivers far more data than any bundle available from KPN or Odido.
A note on Odido’s Internet op Reis passes: Odido does offer day or week passes for internet access abroad. Prices depend on your specific plan and are best checked in the Odido app before departure. Even so, Dutch travellers typically find a ThailandeSIM more cost-effective for trips longer than 2 days.
How to get a Thailand eSIM from the Netherlands — step by step
The whole process takes under 5 minutes and is best completed at home in Amsterdam, Rotterdam, The Hague, or anywhere in the Netherlands before your Schiphol flight:
- Choose your plan based on trip length:
- Short trip (up to 7 days): 35 GB / 7-day plan at USD $8.90 (~€8.20) — ideal for a week in Bangkok or Phuket.
- Standard Dutch holiday (8–15 days): Unlimited / 15-day plan at USD $24.90 (~€23) — covers a Bangkok city break combined with a beach stay.
- Long trip (up to 30 days): Unlimited / 30-day plan at USD $44.90 (~€41).
- Purchase online: Buy at ThailandeSIM.com — pay in USD by Visa, Mastercard, or PayPal. Your Dutch bank converts at the spot USD/EUR rate. QR code arrives in your email within 5–10 minutes.
- Install the eSIM before departure:
- iPhone (XS and later, iOS 16+): Instellingen → Mobiele data → eSIM toevoegen → QR-code gebruiken → scan.
- Samsung Galaxy (S21 and later): Instellingen → Verbindingen → SIM-kaartenmanager → eSIM toevoegen.
- Google Pixel (3 and later): Instellingen → Netwerk en internet → SIM’s → eSIM toevoegen.
- Activate on landing in Thailand: After landing at Suvarnabhumi airport, open your phone settings and turn on Data Roaming for the ThailandeSIM profile. It connects to TrueMove H or DTAC automatically.
⚠ Let op / Important: You can install the eSIM QR code at home in the Netherlands — but only activate it after landing in Thailand. Activating from the Netherlands will cancel the plan immediately.
Tips for Dutch travellers using a Thailand eSIM
- Keep your Dutch SIM in flight mode: Your KPN or Odido SIM stays in your phone. Enable WiFi bellen (WiFi Calling) before you leave. Your Dutch number stays reachable for calls and banking verification codes (iDEAL, Tikkie, DigiD) over hotel WiFi at zero roaming cost.
- Turn off data roaming on your Dutch SIM first: Before enabling data on the ThailandeSIM, make sure data roaming is turned off on your KPN or Odido SIM. This prevents unexpected charges from background app updates on your Dutch line.
- Set ThailandeSIM as your default data line: iPhone: Instellingen → Mobiele data → Standaard lijn. Android: Instellingen → SIM-kaartenmanager → Mobiele data.
- Dutch travellers tend to stay longer: Thailand is a classic destination for extended Dutch holidays — two or three weeks are common. The Unlimited 15-day plan at ~€23 is the best fit for most Dutch visitors.
- Coverage across Thailand: AIS and TrueMove H cover all major Dutch-popular destinations: Bangkok, Phuket, Koh Samui, Koh Phangan, Koh Tao, Chiang Mai, and Pai — all with reliable 4G/5G in tourist areas.
Frequently asked questions
Can I use a Thailand eSIM on a Dutch phone?
Yes, provided your phone supports eSIM and is network-unlocked (SIM-vrij). Most flagship phones sold in the Netherlands support eSIM, including iPhone XS and later, Samsung Galaxy S21 and later, and Google Pixel 3 and later. Phones on a KPN or Odido contract may be SIM-locked for the first 3–12 months — contact your provider to confirm. Phones bought outright (SIM-vrij) from a retailer such as Coolblue, MediaMarkt, or BCC are typically already unlocked.
Is a Thailand eSIM cheaper than KPN roaming?
Significantly. KPN’s best bundle for Thailand costs €39.99 for just 500 MB. A ThailandeSIM costs ~€8.20 (USD $8.90) for 35,000 MB (35 GB) — 70 times more data at one-fifth the price. Even the cheaper KPN bundle at €9.99 only provides 100 MB, which is barely enough for two days of basic use.
Does the EU roaming rule (Roam Like At Home) apply in Thailand?
No. The EU roaming regulation only applies within EU/EEA member states. Thailand is not in the EU, so your Dutch plan’s standard data allowance does not apply there. KPN classifies Thailand as a “Voordeelland buiten de EU” with separate bundle pricing. Odido classifies it as Zone 3. In both cases, you need a specific bundle or pass — or a local Thailand eSIM, which is far cheaper.
Can I use iDEAL and Dutch banking apps in Thailand?
Your Dutch banking apps (ING, ABN AMRO, Rabobank) all work over any internet connection, including the ThailandeSIM. iDEAL SMS verification codes, however, are sent to your Dutch phone number. To receive these, keep your KPN or Odido SIM in your phone on flight mode with WiFi Calling enabled — SMS verification messages will still arrive over WiFi at zero cost.
