Travel eSIM Apps Side by Side: Five Apps, One Column Check
App overview
What each eSIM app does well
HelloRoam, an eSIM platform, sells 185 destinations, and its app runs in 63 languages. Checkout takes 31 currencies through Stripe, with Apple Pay and Google Pay in the app. It sells fixed-data plans and unlimited day plans, and its support replies in your own language around the clock.
- + App in 63 languages
- + 31 checkout currencies
- + 180-day refund on an unactivated eSIM
Airalo lists 200+ destinations. The app sorts plans by country, data size and validity period. Activation uses a QR code or a direct install. Top-up adds data to the profile already on the phone, without closing the app.
- + 200+ destinations
- + $0.55/GB lowest (Thailand 50 GB, 30 days), 30 Oct 2026
- + In-app top-up, no reinstall
Holafly sells unlimited plans by the day, not per GB; its lowest day rate in the 30 Oct 2026 check was $2.15, on a 30-day Italy plan. The app centers on picking a destination and a number of days, so you do not track data use. Holafly's live chat sits inside the app.
- + No stated daily cap
- + 24/7 live chat
- + 180-day refund window
Saily bundles a VPN with its eSIM plans, and the VPN switch sits on the eSIM screen. The app installs the eSIM directly, with no QR code to scan. Its lowest per-GB price in the 30 Oct 2026 check was $0.80, on a 20 GB Austria plan for 30 days.
- + Built-in VPN
- + Unlimited at 3 or 5 GB a day
- + Direct install
Nomad's lowest per-GB price in the 30 Oct 2026 check was $0.34, on a 50 GB Thailand plan lasting 10 days. The app is functional and plain. Support is email only, during business hours, in 2 languages.
- + $0.34/GB lowest (Thailand 50 GB, 10 days), 30 Oct 2026
- + QR code by email, no account
- + Simple plan structure
Activation
Two apps install without a QR code, three do not
Airalo and Saily install an eSIM straight from the app. Holafly and Nomad email a QR code, which means the phone needs a connection to receive it before the trip starts. This site buys no plans, so it publishes no setup duration for any of the five.
| Provider | Activation method |
|---|---|
| HelloRoam | In-app install |
| Airalo | QR code or direct install |
| Holafly | QR code via email |
| Saily | QR code or direct install |
| Nomad | QR code via email, no account |
Our top pick installs the eSIM inside its own app, and the app runs in 63 languages. Airalo and Saily install directly from the app too, with no QR code to scan. This is particularly useful when buying a plan at an airport where camera access is limited.
Holafly and Nomad deliver the QR code via email, which requires a data connection to receive. Install the eSIM before you leave home on WiFi to avoid this dependency. You activate the plan separately once you arrive, so the data does not start running until you turn it on.
Top-up mechanics matter at 14 and 30 days. Airalo adds data to the profile already installed, without leaving the app. Holafly extends unlimited day plans through support, so plan the extension before the last day.
Coverage
Country coverage by provider
HelloRoam sells 185 destinations, Airalo and Holafly list 200+, and Nomad 200. Coverage here means the provider sells a plan for that country. It does not say which local operator the plan attaches to.
Holafly sells unlimited day-rate plans and no fixed-data plans. Where Holafly has no plan for a country, a GB plan from another provider fills the gap.
Our top pick was the cheapest of five providers in 205 of 367 plan cells checked on 30 Oct 2026, across 42 destinations. A rival was cheaper in 160 cells, mostly 20 GB and 50 GB plans, so compare the plan for your country.
Regional plans cover several countries on one eSIM, which suits a multi-country trip. Before you buy one, check that every country on your route is on the regional plan's list.
Pricing
Entry rate, refund window and support hours by provider
| Provider | Entry rate |
|---|---|
| HelloRoam | from $0.29/GB (50 GB for 7 days in Thailand) |
| Saily | from $0.80/GB (20 GB for 30 days in Austria) |
| Airalo | from $0.55/GB (50 GB for 30 days in Thailand) |
| Nomad | from $0.34/GB (50 GB for 10 days in Thailand) |
| Holafly | from $3.90 for 1 day (Japan, read 30 Oct 2026) |
At 7 days, price leads, and our top pick leads on price. Its 7-day unlimited plan was the cheapest of the five in 28 of 41 destinations on 30 Oct 2026. In Japan it costs $19.71, with 2 GB a day at full speed, against $25.00 at Nomad.
At 14 days, the refund window and the top-up path lead. Our top pick refunds an unactivated eSIM for 180 days. Airalo adds data inside the app to the profile already installed.
At 30 days, support hours and the refund window lead. Our top pick lists 24/7 support and refunds an unactivated eSIM for 180 days. Holafly matches the 180-day window, while Airalo refunds within 14 days. On 30-day unlimited price, a rival was cheaper in 29 of 41 destinations on 30 Oct 2026.
Per-GB rates are each provider's lowest rate in the 30 Oct 2026 price check, not prices for one destination. Each destination's 7, 14 and 30-day tiers sit on its best eSIM page.
Support
Customer support when something goes wrong
Support quality matters most when an eSIM fails to connect, a plan does not activate, or a traveler runs out of data in an unfamiliar city. The five providers differ a lot on which channels they open and when.
Our top pick runs live chat, WhatsApp and email around the clock, and its support replies in your own language.
Holafly runs 24/7 live chat in 10 languages. An always-open channel is what business travelers and solo travelers who cannot afford connectivity gaps are paying for.
Airalo offers email and in-app chat during business hours, in 12 languages. For most travelers on standard trips that is fine. For an overnight failure, it is not.
Saily provides email support only, published in 1 language, the narrowest of the five.
Nomad provides email support during business hours, in 2 languages. That suits travelers who have set up an eSIM before, less so a first-time user.

FAQ
eSIM app questions answered
Q1Which eSIM app is easiest to use for first-time travelers?
Airalo and Saily install an eSIM straight from the app, with no QR code to scan. Holafly and Nomad email a QR code, so install those on WiFi before you fly. For a first eSIM on a 30-day trip, Holafly lists 24/7 live chat.
Q2Can I manage multiple eSIMs across countries in one app?
Yes. You can hold several installed eSIM profiles and switch between them in your phone's settings. Airalo's app shows your installed plans with their data balance and expiry date. The number of profiles a phone holds depends on the model.
Q3Do eSIM apps work on Android as well as iPhone?
Yes. All five providers on this page sell eSIMs for iOS and Android phones. The phone must support eSIM and be carrier-unlocked. Check your model on the provider's compatibility page before buying.
Q4Is it safe to buy an eSIM through an app?
Yes, when you buy inside the provider's own app or site. The eSIM installs through a QR code or a direct install in the app. Pay through the app's own checkout, never through a link sent in a message.
Q5Which eSIM app has the widest customer support?
HelloRoam runs live chat, WhatsApp, and email around the clock, and its support replies in your own language, the widest reach of the five. Holafly also runs 24/7 live chat, in 10 languages. Airalo covers email and in-app chat during business hours in 12 languages. Saily and Nomad are email only. This site publishes no reply-time figures.
Q6Can I get a refund on an eSIM I have not used?
Yes, inside each provider's window for an unactivated eSIM, from 14 days at Airalo to 180 days at HelloRoam and Holafly. Check device compatibility before you buy.
