Saily eSIM review 2026: is it worth it, pros, cons and how to buy

This review is based on the brand's published plans, policies and help pages as of October 2026, not on a test trip. Saily's site blocks automated readers, so the details we could confirm come from its App Store listing. Everything else comes from search snippets and is marked unconfirmed.

Who is behind Saily

The developer on Saily's App Store listing is Nordvpn S.A., which ties the app to Nord Security. That is the only ownership detail we could confirm this round. A 2024 launch has been reported but we could not verify it on an official page. This site sells eSIMs too, so we compare plainly and do not rank ourselves above other brands.

How buying works in the app

Saily sells mainly through its app. The steps below are the usual order for buying an eSIM in an app, and the real screens may differ, so follow the on-screen text.

1. 1Check your phone firstMake sure the phone supports eSIM and is not network-locked before you pay anything.
2. 2Install the app and pick a destinationChoose the country or plan type the app offers, then compare the GB size with the number of days.
3. 3Thanh toánPrices are shown in US dollars, so ask your bank about the card's currency conversion fee.
4. 4Install the eSIMFollow the in-app steps on Wi-Fi, ideally before you leave.
5. 5Start the plan on arrivalThe App Store listing says plans start on arrival. For how long an unused eSIM stays valid, read the plan page.

Extra features the app lists

Saily's App Store listing names these features, and this is the full set we could confirm.

• Ad blocker and web protection
• An optional virtual US +1 number, paid as an add-on
• Top-ups
• Shared plans for up to 4 people
• Gói cước Cruise
• The Saily Ultra subscription
• Plans that start on arrival

The listing does not explain the details, such as what Saily Ultra includes or how sharing works. Read those screens in the app before paying.

Plan types and pricing model

A short trip of 4 to 5 days rarely needs unlimited. A fixed-GB plan sized to your real use is usually enough. Heavy map and video users can consider unlimited, then check whether the speed after the daily threshold is acceptable.

What we could not confirm

Language and support

Thai is not in the app's language list, which has English plus 16 others, per the App Store. Install steps and chats with support will be in English, or another listed language. The eSIM settings on your phone, such as the mobile data and roaming menus, stay in your device language, which helps there. A seller with a Thai team, this site included, is easier where you need to talk to a person.

Pros and cons

Who Saily suits

It suits travellers who read English comfortably, like to run everything from an app, and want an ad blocker or a shared plan for a group of up to 4. Cruise travellers have a dedicated plan to look at.

If you want Thai menus and support, payment in baht, or a QR by email with no app, look at sellers that work that way. This site is one such option. Before deciding, compare the current price from both sides for the same country and number of days, and read the guide “Comparing eSIM providers fairly”.
