An eSIM gives you working mobile data the moment you land, without hunting for a SIM kiosk. For most digital nomads the pattern is simple: arrive on a regional eSIM like Airalo, then switch to a cheap local plan once you settle for more than a couple of weeks.
- Airalo has the widest country and regional coverage, pay-per-GB.
- Holafly suits heavy unlimited use, but check tethering limits.
- Local carrier eSIM is cheapest per GB for stays over ~2 weeks.
- Keep your home SIM active for banking and 2FA codes.
How I use eSIMs on the road
My routine: buy a small regional eSIM before I fly (1–3 GB), activate it on landing so I can call a ride and check maps, then within a few days buy a local eSIM or physical SIM with a proper monthly allowance. The travel eSIM stays as a backup and for short trips to neighbouring countries.
A travel eSIM is a bridge, not a home. It gets you online on day one; a local plan gets you online cheaply for the month.
The main options, compared
| Provider | Best for | Pricing model | Watch out for |
|---|---|---|---|
| Airalo | Widest coverage, short trips | Pay per GB, regional bundles | Per-GB cost adds up on long stays |
| Holafly | Unlimited data users | Flat unlimited per day/period | Tethering restricted on some plans; no local number |
| Nomad / Saily | Competitive regional bundles | Pay per GB | Coverage narrower than Airalo in some regions |
| Local carrier eSIM | Stays over ~2 weeks | Local monthly plans | Setup sometimes needs a local ID or shop visit |
Coverage and mobile prices vary a lot by country. Compare bases on internet and connectivity before you buy data.
Compare destinations →When a local eSIM wins
- You'll be in one country for more than two weeks.
- You need a local phone number (deliveries, ride apps, bank OTPs).
- You use a lot of data — local plans are often 5–10× cheaper per GB.
- Coverage in rural areas — local carriers usually beat roaming partners.
Setup and gotchas
- Check your phone is eSIM-capable and carrier-unlocked before you rely on this.
- Install the eSIM on home Wi-Fi before you fly; activate it on arrival.
- Set the travel eSIM as data-only and keep your home SIM for calls/SMS 2FA.
- Screenshot the APN settings in case auto-config fails.
- Most eSIMs can't be moved to a new phone — buy fresh if you upgrade.

FAQ
What is the best eSIM for digital nomads?
Airalo is the usual default for its coverage and per-GB pricing on short trips. For long stays in one country, a local carrier eSIM is cheaper. Holafly is worth considering if you want unlimited data and don't need heavy tethering.
Should I use a travel eSIM or a local SIM?
Use a travel eSIM for the first days and for short hops between countries. Switch to a local SIM or eSIM once you're staying somewhere more than about two weeks — it's far cheaper per GB and often gives you a local number.
Can I keep my home number while using a travel eSIM?
Yes. Most phones support two SIMs at once. Keep your home SIM active for calls and SMS two-factor codes, and set the travel eSIM as your data line.
Do eSIMs work for hotspot/tethering?
Most do, but some unlimited plans (notably certain Holafly plans) restrict or cap tethering. Check the plan details before buying if you need to hotspot a laptop.
