Best overall: Airalo — the biggest choice of destinations and pay-as-you-need data packs. Best for heavy data users: Holafly — unlimited-data plans at a higher price. Best value alternative: Nomad — competitive per-GB pricing. Check that your phone is unlocked and eSIM-compatible before you buy, and install the eSIM before you fly.
Roaming charges have a bad reputation for a reason: a few days of data on a home carrier’s international plan can cost as much as a hotel night. Travel eSIMs fix that by letting you buy local-rate data for the country you’re visiting and install it digitally, with no plastic SIM card to swap.
Here’s how the main eSIM providers compare on price, coverage, and who they’re best for. Plan prices change constantly and vary by country, so treat the guidance below as a framework and check the live price for your destination.
Best Travel eSIM Providers in 2026
1. Airalo — Best Overall
Airalo is the largest travel eSIM marketplace, with local, regional, and global packs covering a huge range of countries. You choose the amount of data and number of days, so you pay for what you need, and small packs for a short trip can be very cheap compared with roaming.
Its app makes it easy to install, top up, and manage multiple eSIMs. Airalo packs are data-only, so you’ll use apps like WhatsApp or FaceTime for calls. It’s the best starting point for most travellers.
2. Holafly — Best for Heavy Data Users
Holafly sells unlimited-data plans for many destinations, which suits people who stream, hotspot for work, or don’t want to think about data limits. Plans are priced by the number of days rather than by gigabytes.
That convenience costs more per day than a small Airalo pack. Unlimited plans may also apply fair-use policies on speed or hotspot use, so check the details for your destination.
3. Nomad — Best Value Alternative
Nomad offers a clean app, straightforward pricing, and a broad list of countries, and its plans are often competitive with Airalo’s on a per-gigabyte basis. It’s a good choice if you like comparing prices before you pick a provider.
Coverage and pricing vary by destination, so check Nomad’s rate for your country against Airalo before buying.
4. Saily — Best If You Already Use NordVPN
Saily comes from the makers of NordVPN and includes some privacy-focused extras, like ad-blocking and data-safety features. It offers country and regional plans with simple purchase and installation.
Prices vary by destination, so compare it against other providers for your trip. It’s a good fit if you value the extra security features.
eSIM vs Roaming vs Local SIM
| Option | Typical cost | Convenience | Best for |
|---|---|---|---|
| Travel eSIM | Low to moderate | Install before you fly | Most travellers |
| Carrier roaming pass | Often around $10 per day | Very easy, keeps your number | Very short trips |
| Local SIM card | Often the cheapest | Buy on arrival, ID may be needed | Long stays |
How to Set Up a Travel eSIM
- Check compatibility. Your phone must support eSIM and be network-unlocked. Most recent iPhones and many Android phones do.
- Buy and install before you fly. Install over Wi-Fi, but only switch the data line on after landing.
- Turn off data roaming on your main SIM. This prevents surprise charges while you use the eSIM.
- Keep your home SIM active for calls and texts. Many banks send verification codes by SMS.
- Save the QR code and details. You may need them if you have to reinstall.
How Much Data Do You Need?
Light users, such as those who check maps, messages, and email, can get by on 1–3GB for a week. If you upload photos, use ride-hailing apps, or stream music, 5–10GB is safer, and anyone hotspotting a laptop should consider a larger pack or an unlimited plan. It’s usually cheaper to buy a bit more data than to top up repeatedly, but avoid overbuying since unused data typically expires with the pack’s validity period.
For multi-country trips, regional packs (such as Europe-wide plans) usually cost less than buying a separate eSIM for each country, and they save you from swapping plans at every border.
Frequently Asked Questions
How does a travel eSIM work?
An eSIM is a digital SIM that you install on your phone by scanning a QR code or using an app. It connects to a local network in the country you’re visiting, giving you data at local rates without changing your physical SIM.
Can I make calls with a travel eSIM?
Most travel eSIMs are data-only, so you make calls with apps like WhatsApp, FaceTime, or Google Meet. If you need a local phone number, look for a provider that offers one or use a local SIM.
Is an eSIM cheaper than roaming?
Usually, yes. A small data pack for a week can cost far less than a few days of a carrier’s international day pass, though some carriers now include roaming in their plans, so check yours first.
Will my phone work with an eSIM?
Most phones released in the last few years support eSIM, but your phone must also be unlocked from its original carrier. Check your phone’s settings or manufacturer page to confirm.
Final Thoughts: For most travellers, Airalo is the best place to start, Holafly is worth the premium if you’d rather not watch your data, and Nomad and Saily are good alternatives if the price is right. Check your phone is compatible and unlocked, and install before you leave home.
