Is Saily a Good eSIM for Japan? Reliability and Price in 2026

Short answer. For most Singapore travellers heading to Japan in 2026, Saily can be a good eSIM if your phone is carrier-unlocked and supports eSIM, and its Japan plan's price per GB beats the alternatives on the day you buy. Saily is a prepaid travel eSIM made by Nord Security, the company behind NordVPN, and its App Store listing describes data in 200+ destinations, top-ups in the app, and 24/7 support. Before you pay, go through ShopBack so part of what you spend comes back to you.

ShopBack Singapore is a free app and website that gives you money back when you shop online at thousands of stores, including Saily. You open the store from ShopBack, buy as normal, and part of what you spend comes back to your ShopBack account as cash you can withdraw. New members can join free at shopback.sg/signup.

Saily's App Store listing in Singapore, Nord Security's product pages, Apple's support page on using eSIM while travelling, and the Terms on the Saily page on ShopBack, all at the time of writing in October 2026.

The verdict

Saily is a sensible pick for a Japan trip when you want a simple prepaid data plan you can set up in Singapore, keep your own number on, and top up from the app. It is less of a fit if your phone is locked to your Singapore telco, or if your telco's roaming pass works out cheaper for your trip length. Compare the Japan plan on Saily with two or three other eSIMs on the day, then go through ShopBack before you pay for whichever wins.

Saily eSIM Japan from Singapore in 2026: before you buy

In 2026, the three checks that matter most before you buy a Saily Japan eSIM from Singapore are your phone, your plan size and your telco's alternative.

1. Is your phone eSIM-ready and unlocked? Apple says iPhone XS, XS Max, XR and later support eSIM, and that your iPhone cannot be locked to a network provider if you want to use another provider's eSIM abroad. To check on an iPhone, go to Settings, General, About: "No SIM Restrictions" next to Network Provider Lock means it is unlocked. For Android, check your phone maker's support page.
2. How much data will you use? Maps, ride-hailing, translation apps and social media add up. Pick a plan that covers your trip with room to spare, or one you can top up easily.
3. What does your Singapore telco offer? Apple suggests checking whether your provider includes roaming or offers travel passes you can buy ahead. Compare that price with the eSIM.

Install before you fly. Apple notes that your iPhone usually needs to be on Wi-Fi to set up an eSIM. Install the Saily eSIM at home in Singapore, then switch on the Saily line for data when you land in Japan.

Is Saily eSIM reliable?

Saily says it connects you to local networks at your destination, so reliability in Japan depends mostly on that local network and on where you go.

To judge reliability for your trip:

• Check the network on the Japan plan page before you buy.
• Read recent reviews on app stores and review sites such as Trustpilot, focusing on Japan trips and on how support handled problems.
• Keep a backup. Leave your Singapore line on for calls and texts, and know how to switch data back to it if you need to.

Saily reviews, support and refunds

Before you buy any eSIM, it is worth knowing where to read reviews, how to reach support, and what the refund rules are.

Reviews. Look for Saily reviews on app stores and on review sites such as Trustpilot. Ratings change over time, so read the most recent ones, and look for reviews from people who used it in Japan.

Customer service. Saily's App Store listing says its support team is ready to help 24/7 with setup, coverage or data plan questions. Contact it through the app or the help section on saily.com.

Refunds. Read Saily's refund policy on saily.com before you buy. With eSIMs, whether the plan has been installed or used often decides whether you can get money back.

Is Saily eSIM reliable, and how does it compare on price?

On price, there is no single answer: Saily can be cheaper or dearer than other eSIMs for Japan depending on the plan size, the trip length and current offers, so compare on the day you buy. On reliability, the network named on the plan matters more than the brand.

A fair way to compare:

What to compare	How to do it
Price per GB	Divide the plan price by the data included.
Price per day	Divide the plan price by the days of validity you will actually use.
Fixed data vs unlimited	Unlimited plans suit heavy users; fixed plans can be cheaper for light users.
Top-up cost	Check how much extra data costs if you run out.
When validity starts	Saily says the plan starts the moment you land; check this for each seller.
Telco roaming pass	Compare the eSIM total with your Singapore telco's pass for the same days.

Other eSIM stores on ShopBack Singapore. Besides Saily, travel eSIMs are sold by Airalo, Nomad, Jetpac and Klook, among others. Check the same Japan trip on two or three of them; each has strengths depending on plan sizes and offers on the day.

How ShopBack lowers the price of your Saily eSIM

Plan the trip, then book through ShopBack. ShopBack is a post-purchase discount: go through it before you pay and the effective price drops.

Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles. Once it confirms, you can withdraw it, subject to ShopBack's withdrawal terms.

How to do it, step by step:

1. Open ShopBack Singapore (app or website) and search for Saily.
2. Check the live rate shown on that page. The Saily page on ShopBack shows which purchases earn Cashback and the live rate.
3. Open Saily from its ShopBack page and finish the order in the same visit. On your phone, open Saily from the ShopBack app and finish the order there.
4. Cashback shows as pending in your ShopBack account soon after you pay, and confirms once the order is complete.

Working out the effective price. Your effective price is what you pay minus the Cashback that comes back. Go through ShopBack before you pay and the Cashback tracks to your ShopBack account.

---

Promo codes and ShopBack

No code needed: go through ShopBack before you pay and part of what you spend comes back as Cashback.

---

Card rewards and ShopBack

You can usually earn Cashback and your DBS, UOB or OCBC card rewards on the same Saily purchase, because they come from different places.
