Our verdict
Saily suits short trips abroad where you want clearly priced, easy-to-install data, backed by strong ratings on the App Store, Google Play and Trustpilot. The trade-offs are data-only service (except the US phone-number add-on), no refund for unused data after expiry, and a privacy policy that allows behavioral advertising through partners.
Best for: Travelers who want to buy an eSIM before a trip and be online on landing
Skip it if: Anyone who needs a local phone number for calls or OTP codes at the destination
Pros
- Per-destination prices are public; a Vietnam eSIM, for example, starts at $3.99 for 1 GB/7 days
- High ratings: App Store 4.7, Trustpilot 4.7, Google Play 4.5
- eSIM can be installed before the trip, and the plan activates on arrival
Cons
- Data-only plans, with no phone number apart from the US number add-on that requires identity verification
- Unused data is lost at expiry with no refund
All pros and cons · Who is it for?
Pros
- Full refund available within 30 days if the plan is not activated
- 24/7 live chat in the app, per the company
Cons
- The privacy policy mentions behavioral advertising through partners
- Google Play rating (4.5) is lower than the App Store and Trustpilot (4.7)
Best for
- People who need small to mid-size data bundles (1 to 20 GB) for a specific destination
Skip it if
- Long-term residents of one country, where a local carrier plan is likely a better fit than per-GB travel pricing

Experience & key features
What Saily is
Saily is a travel eSIM service published by Nord Security on Google Play (Nordvpn S.A. on the App Store). The app launched in 2024 (Product Hunt lists 27 March 2024). You buy a data plan per destination, install the eSIM, and the plan activates when you arrive or 180 days after purchase. The company says plans cover over 200 destinations.
How it works and features
After purchase you download the Saily app, install the eSIM and enable data roaming for the plan. One eSIM can add more destinations through top-ups. Beyond country plans, Saily sells regional plans (such as Europe), global plans, a US phone number from $0.99 per month, and an Ultra plan with unlimited global data plus airport lounge access, fast-track service and NordVPN, per the homepage. Plans are data-only; a physical SIM can still handle calls.
Pricing and value
Per the Vietnam eSIM page: 1 GB/7 days $3.99, 3 GB/30 days $7.99, 5 GB/30 days $10.99, 10 GB/30 days $17.99, 20 GB/30 days $28.99, plus unlimited plans. Prices are one-off purchases, and the page shows 3% back in Saily credits. If the plan is not activated you can request a full refund within 30 days; expired data is not refunded.

Versus alternatives
Other travel eSIM services include Airalo and Holafly. Airalo also sells country, regional and global plans like Saily. Saily's differentiators are its publisher, Nord Security (the NordVPN company), and a US phone-number add-on. Compare prices for the same data size and duration on each site before buying, since prices vary by destination.

Cancellation & refunds
Per Saily's refund guide (29 Sep 2025): if the eSIM is not installed, or is installed but the plan is not activated, a full refund can be requested within 30 days of purchase. Activated plans count as used, so a full refund is not guaranteed; Saily may consider a partial or full refund if under 1% of data was used or if you could not use it because of Saily quality issues. Refunds are excluded if you delete your account after purchase or abuse is found. The terms of service state that unused data is lost at expiry with no refund.
Privacy
Per the privacy policy (updated 30 Oct 2026), Saily Inc. (Delaware, US) is the data controller, working with Saily UAB (Lithuania) and CyberQuay Pty Ltd (Australia). It collects name, email, payment data, approximate IP-based location and in-app event data. It may also process the destination of network traffic and the estimated app category, to show data use per app and to handle refunds. The policy says Saily partners with third parties to run ads on its website and manage its ads elsewhere, including behavioral advertising. For the phone-number feature it must run identity verification (KYC) and retain call and SMS traffic records under telecom rules, which limits deletion rights for that data. Plans are data-only, so a physical SIM can stay active for calls and texts.

Frequently asked questions
Does Saily include a phone number for calls?
Data plans do not. Saily offers a separate US phone number from $0.99 per month, with identity verification in the app after purchase.
When does a Saily plan start counting days?
Per the homepage, the plan activates when you reach the destination or 180 days after purchase, whichever comes first. Per Saily's refund guide, you cannot activate it manually.
Can I get a refund if I do not use it?
Yes, if the eSIM is not installed or the plan is not activated, you can request a full refund within 30 days of purchase. Activated plans are reviewed case by case.
Who owns Saily?
The Google Play listing names Nord Security as the publisher and the App Store lists Nordvpn S.A. The privacy policy names Saily Inc., a Delaware (US) corporation, as data controller.

Why this score
Three-step flow (choose a plan, install the eSIM, enable data roaming) with auto-activation on arrival; 4.7 on the App Store and Trustpilot.
Why this score
Country, regional and global plans, top-ups, a US phone number and an unlimited Ultra plan, but the core remains data-only.
Why this score
A $3.99 entry for 1 GB in Vietnam is a low starting price for light use, but prices climb with data and expired data is not refunded. A like-for-like price check against rivals was not possible from the pages opened.
Why this score
Based on public reviews: Trustpilot's summary points to fast setup and mostly positive experiences, while noting some reviewers hit connection problems. No independent speed test was found.
Why this score
A help center, 24/7 in-app chat, email and an automated Refund Center. Trustpilot's AI-generated summary praises patient staff but also notes some reviewers found support unhelpful with connection problems.
Why this score
A detailed policy that names the entities involved. Lowered for collecting payment, in-app event and network-traffic data, behavioral ads through partners, and KYC for phone numbers.
