When I was planning my trip to Hong Kong, one of the first things on my checklist was finding a reliable eSIM. It will be my first time there, and staying connected was non-negotiable. I’ve tried a few different eSIM brands on past trips, so I know the drill by now. But for my recent trip, I went with Saily eSIM.
In this post, I’m sharing why I chose Saily eSIM over other brands. How it worked for me, how much it costs, and the standout features that actually made a difference while traveling.
If you’re overwhelmed by all the eSIM options out there and wondering if Saily eSIM is worth it, then this review is for you.

What is Saily eSIM and How Does it Work?
Saily eSIM is basically a digital SIM card for travel. It works just like a regular SIM, but no physical SIM swap needed. It’s built right into your app and lets you connect to mobile data in 200+ destinations worldwide.
One of my favorite things about it? You only need one eSIM for all your trips. Whether you’re hopping between countries or planning future travels, you can just top up through the Saily app and stay connected wherever you go. No reinstalling. No new QR codes.

How Much Does Saily Cost?
Saily eSIM plans start at just $1.99 USD, depends on where you’re headed. For example, if you’re off to Japan for a week, you can grab a 7-day plan with 1GB of data for only $3.99 USD. A 30-day plan with 20GB will only set you back $24.99 USD.
Traveling to multiple countries? Saily’s got regional plans too, for places like Asia, Europe, Africa, and more, starting at just $4.99 USD. There’s even a global plan if you’re planning to country-hop across continents.
How to Set Up Saily eSIM
Step 1: Check Device Compatibility
Make sure your phone is eSIM compatible! Most newer smartphones support eSIMs, but it’s always worth double-checking just to be safe. Also, if your phone is still carrier-locked, eSIMs won’t work.
You can check out Saily’s full list of compatible devices here. If your phone’s on the list, you’re all set!
Step 2: Choose Your Plan
Pick a Saily eSIM plan that fits your travel plans. You can choose by country, go for a regional plan if you’re visiting multiple countries, or grab a global plan if you’re hopping all over.
Select how many days you need, how much data you require, and just add to cart.

Step 3: Purchase the eSIM
Once you’ve picked your plan, it’s time to check out. Sign up or login, enter your payment details, and complete the payment, it’s super straightforward. You’ll get an email right after with your eSIM QR code.
Step 4: Install and Activate your eSIM
Once you get the email with your QR code, it’s time to install and activate your eSIM. Just follow these simple steps:
- Long-press the QR code in the email and open the link in your browser.
- On Android, you can do the same, or use Google Lens to scan the QR code from your Gallery.
- Follow the on-screen prompts to install the eSIM, and make sure roaming is enabled on your device.
- After installation, set Saily as your primary data line.
- Optional: To avoid confusion, rename the eSIM to “Saily” if you have multiple SIM/eSIMs on your phone.
That’s it! Your Saily eSIM will automatically activate as soon as you land at your destination.
Security Features
What makes Saily stand out is that it’s backed by Nord Security. It’s the same trusted company behind NordVPN. Here are some security features built right into the app:
Virtual Location
In the past, I always had to buy a separate VPN on top of my eSIM to secure my browsing. With Saily eSIM, I get data and built-in privacy features in one app.
You can even choose from 115+ virtual locations and route your connection through remote servers for extra privacy. Total game changer, especially if you want to access geo-restricted content. I was able to open TikTok in Hong Kong because of this. Yes, really!
Ad Blocker
Tired of annoying ads popping up while you’re trying to Google something on the go? Same! With Saily’s built-in ad blocker, you can cut down on all that screen clutter and save data while you travel.
Web Protection
Saily uses DNS filtering to block trackers, sketchy websites, and even phishing attempts before they reach your phone. It also helps cut down on invasive ads and keeps online tracking to a minimum.

My Saily eSIM Experience in Hong Kong
I used Saily eSIM for four days in Hong Kong, and honestly? I was impressed. The connection was solid the entire time.
I won’t get into the techy details, but as a traveler who just needs reliable data on the go, Saily did the job. Google Maps, WhatsApp, and regular browsing all worked smoothly. My Instagram Stories uploaded fast (even videos!), and I was even able to use TikTok, which is banned in Hong Kong. Thanks to their Virtual Location feature!
I haven’t tested Saily in other countries yet, but I’ll be using it on my next trips and will update this post once I’ve tried it abroad. So far, though, I don’t see any reason why it wouldn’t work just as well elsewhere.
Final Thoughts about Saily eSIM
Saily eSIM is a great travel eSIM. If you’re like me and just need to stay connected for maps, messages, social media, and occasional video calls, then Saily eSIM is a solid choice. It’s affordable, easy to set up, and comes with security features that most eSIMs don’t offer.
But if you’re someone who streams a lot, downloads shows from Netflix for the plane ride, or is always online, you might want to look into Holafly eSIM, which offers unlimited data. Just something to keep in mind when choosing the right eSIM for your trip! 🙂
If you end up trying Saily on your next trip, I’d love to hear how it worked for you too. Safe travels! 🌍📱
