- Saily — newest, top speeds on Vodafone/Orange APNs in Europe.
Install in 60 seconds
- Buy the plan on the provider's app or web.
- Scan the QR code (Settings → Cellular → Add eSIM).

- Toggle Data Roaming on for the eSIM only.
Coverage check before you buy
Every provider lists the local networks they piggy-back on — pick one that uses the strongest in your destination (e.g. Vodafone in most of EU, NTT Docomo in Japan, AIS in Thailand, Telkomsel in Indonesia). Speed varies by underlying network, not by brand.

Travel eSIM — questions we get most
What is a travel eSIM?add
An eSIM is a SIM profile installed on your phone via a QR code, no physical card needed. You buy data for a country/region online and install it before your flight; on arrival it auto-connects to a local network.
Will an eSIM work on my phone?add
Yes on iPhone XS or newer, Pixel 4 or newer, Samsung Galaxy S20+/Z Flip/Z Fold and most 2022+ Android flagships. Carrier-locked iPhones (US Verizon/AT&T/T-Mobile before iPhone 14) need to be unlocked.
How much does a travel eSIM cost?add
Regional bundles range from $5 for 1GB / 7 days (Asia, Europe) to $47 for unlimited data for 15 days. Per-GB price is usually $1.50–$5; "unlimited" plans throttle after 1–3GB/day.
Can I make calls and use hotspot on an eSIM?add
Most travel eSIMs are data-only — voice calls use WhatsApp/FaceTime over data. Hotspot is supported on Airalo, Nomad and Saily; Holafly throttles or blocks tethering on some plans.
Will it cover multiple countries?add
Yes — regional bundles like Airalo Eurolink (39 European countries), Discover+ (global), or Asialink cover one purchase across borders. For 3+ countries a regional plan is almost always cheaper than country-by-country.
