There’s something magical about wandering cobblestone streets in Edinburgh, sailing the coast of Croatia, or watching lanterns float in the skies of Thailand. But nothing can pull you out of the moment faster than scrambling for Wi-Fi or paying eye-watering roaming fees. That’s where eSIMs step in—digital SIM cards that keep you connected from the moment your plane lands.
Whether you’re tracing your roots in Scotland, sipping espresso in Rome, or exploring temples in Japan, choosing the right eSIM for a long journey (15–20+ days) makes all the difference.
Why eSIMs Are a Game-Changer for Travelers
- No physical SIM card: Just scan a QR code, and you’re online.
- Multiple countries, one plan: No more juggling tiny cards at every border.
- Budget-friendly: Skip $10–$15/day roaming charges from your home carrier.
- Flexibility: Many eSIMs cover entire regions—Europe or Asia—with one plan.
Best eSIMs for the UK & Europe
🌍 Perfect for trips to Scotland, Ireland, Italy, Greece, Croatia, Germany, Belgium, The Netherlands, and beyond.
- Ubigi Europe Unlimited—Great for heavy users. You get up to ~60 GB high-speed data in 30 days, then reduced speeds (still fine for maps and messages). Hotspot allowed.
- Holafly Europe Unlimited—the easiest “set it and forget it” option. Unlimited data across many countries. Check hotspot details per country.
- Airalo Eurolink/Discover—Budget-friendly fixed data (5–50 GB). Top up in the app whenever you need. Includes 40+ countries.
- Orange Holiday eSIM—Includes data plus calls and texts. Handy if you need to make restaurant reservations or receive confirmations.
💡 Tip: Post-Brexit, UK carrier roaming in the EU can be expensive. Regional eSIMs often save you a bundle.
Best eSIMs for Asia
🌏 Ideal for journeys through Japan, South Korea, Thailand, Vietnam, and more.
- Nomad Asia Regional—Affordable, hotspot-friendly, and strong local partners (like KT in AIS in Thailand). Excellent for laptop tethering.
- Holafly Asia Unlimited—Unlimited data across multiple countries. Easy to install, though hotspot use can be limited in some regions.
- Airalo Asialink—Value option with flexible data packages and top-ups, plus coverage in dozens of Asian countries.
✨ Country highlights:
- Japan: Ubigi (partnering with Docomo) or Airalo for value; Holafly if you want unlimited.
- South Korea: Nomad regional plans or KT eSIMs if you need local calls/SMS.
- Thailand: Nomad is hotspot-friendly; Holafly for unlimited.
- Vietnam: Third-party eSIMs like Airalo or Nomad work well. Local airport eSIMs exist but can be hit-or-miss—better to arrive prepared.
The Truth About “Unlimited”
Many unlimited eSIMs come with a Fair Use Policy:
- Ubigi Unlimited: ~60 GB high-speed before throttling.
- Holafly Unlimited: Truly unlimited but may restrict tethering in some countries.
- Nomad: Hotspot-friendly plans with clear data terms.
💡 Rule of thumb: If you’re uploading photos, streaming, or tethering a laptop, check the hotspot policy before buying.
How to Check if Your Phone Supports eSIM
Most modern phones (especially iPhones and Samsung Galaxy) are eSIM-ready—but it’s worth double-checking before you travel.
📱 For iPhones
- iPhone XR, XS, XS Max, and later all support eSIM.
- iPhone 14 and newer (in the U.S.) are eSIM-only (no SIM tray).
- Check: Go to Settings > Cellular > Add eSIM or Add Cellular Plan. If you see the option, your phone is compatible.
📱 For Samsung Galaxy
- Galaxy S20, S21, S22, S23, and S24 series (except some U.S. carrier models like Verizon’s S20).
- Galaxy Note 20 series.
- Galaxy Z Flip and Z Fold models from 2020 onward.
- Check: Go to Settings > Connections > SIM Manager > Add eSIM. If the option appears, your phone is ready.
Quick Tips Before You Fly
- Install the eSIM while on Wi-Fi at home (some countries like Turkey block access to eSIM sites).
- Turn off data roaming on your physical SIM and use the eSIM for data.
- Use Wi-Fi Calling or WhatsApp/FaceTime for calls if your eSIM is data-only.
- Save the QR code/email in your inbox or cloud in case you need to reinstall.

✨ Pro tip from Timeless Travels with Sandy: Choose your eSIM based on how you travel. Light user? Airalo. Heavy streamer or remote worker? Ubigi. Love simplicity? Holafly. Tech-savvy and hotspot-dependent? Nomad.
Wherever you roam—Europe, Asia, or both—the right eSIM is your passport to staying connected.
