What Saily is and how to get it on your device
Saily is a mobile app that lets you buy and activate eSIM plans — digital phone plans that work without a physical SIM card. You download the Saily app to your phone, browse available plans for your destination, and activate them directly in the app. The app works on both iPhone and Android devices, and the whole process takes a few minutes once you have the app installed.
Saily is made by Holafly, a company that sells international mobile plans. The app itself is free to download; you only pay if you choose to purchase a plan through it. Before you start, check that your phone supports eSIM — most modern iPhones (iPhone XS and newer) and many Android phones do, but older devices may not.
Key Takeaways
- Download Saily from the App Store on iPhone or Google Play on Android, then open the app and create an account with your email address.
- Your phone must support eSIM technology, which is standard on iPhones from XS onward and many newer Android phones, but not all devices.
- After you download and install the app, you can browse plans by destination country and see prices before you commit to buying anything.
- Activating a plan through Saily happens inside the app and takes just a few minutes; the eSIM is installed directly to your phone's digital SIM slot.
Download Saily on iPhone
Open the App Store on your iPhone and tap the search icon at the bottom of the screen. Type "Saily" into the search box. The official Saily app will appear at the top of the results — it has a blue icon with a white airplane symbol. Tap the cloud icon with a downward arrow (labeled "Get") to download it.
Your phone will ask you to authenticate using Face ID, Touch ID, or your Apple ID password. Complete whichever method your phone shows. The app will then download and install automatically. Once it finishes, the "Get" button changes to "Open" — tap that to launch Saily for the first time.
Download Saily on Android
Open Google Play on your Android phone and tap the search icon at the bottom. Type "Saily" into the search box. The official Saily app will show up first — look for the blue icon with the white airplane. Tap "Install" to download it.
Google Play will show you what permissions the app needs (things like access to your phone's settings and contacts). Tap "Install" again to confirm. The app will download and install. Once finished, the "Install" button becomes "Open" — tap that to start Saily.
Create your Saily account
When you open Saily for the first time, you will see a screen asking you to sign up. Tap "Sign up with email" and enter your email address. Saily will send you a confirmation link to that email — check your inbox (and spam folder if you do not see it) and click the link to verify your account.
After you confirm your email, you can set a password and add your name and phone number if you want to. These details help Saily contact you if there are issues with your plan. You do not have to fill in everything right away — you can browse plans and come back to complete your profile later.
Check that your phone supports eSIM
Before you buy a plan, make sure your device can use eSIM. On iPhone, go to Settings, tap General, then About. Look for a line that says "Dual SIM" or "Dual SIM (Nano-SIM and eSIM)" — if you see either of those, your phone supports eSIM. iPhones from XS, XS Max, and XR onward all support it.
On Android, the process varies by phone maker. Go to Settings and search for "SIM" or "eSIM." If you see options for eSIM or digital SIM, your phone supports it. Most phones from 2020 onward do, but some budget models do not. If you cannot find eSIM settings, your phone likely does not support it, and you will not be able to use Saily plans.
Browse and understand Saily plans
Once you are signed in, the Saily app shows a map where you can tap the country you are traveling to. The app then displays all available plans for that destination — you will see the price, how much data each plan includes, and how long it lasts. Plans range from a few days to a month, and prices vary widely depending on the country and data amount.
Tap any plan to see more details: exactly what networks it works on in that country, whether it includes calls and texts, and the expiration date. Read these details carefully because once you buy a plan, you cannot change it. If you are not ready to buy, just close the app — your account stays active and you can come back anytime.
Activate a plan after purchase
When you decide to buy a plan, tap it and follow the payment steps. Saily accepts credit and debit cards. After payment goes through, the app will guide you through activating the eSIM. You will see a QR code or a manual entry option — most phones work better with the QR code method.
If you use the QR code, your phone will open the camera and scan it automatically. You will see a popup asking to add a cellular plan — tap "Add eSIM" or "Continue" depending on your phone. The eSIM downloads to your phone in a few seconds. You can then switch to it in your phone's settings whenever you land in that country. The plan stays on your phone until it expires, even if you switch back to your regular SIM.
Frequently Asked Questions
Can I use Saily if I do not have WiFi when I land?
You need WiFi or a working cellular connection to download the eSIM after you buy it. Download and activate your plan before you travel, while you still have access to your home network. Once the eSIM is on your phone, it works without WiFi.
What happens if my phone loses the eSIM after I activate it?
If your eSIM stops working, open the Saily app and look for a "Reinstall" or "Reactivate" option for that plan. You can reinstall it as long as the plan has not expired. If you cannot find the option, contact Saily support through the app.
Can I have Saily and my regular phone plan at the same time?
Yes. Your phone can hold both your regular SIM and an eSIM at the same time. You switch between them in your phone's settings. When you arrive at your destination, switch to the Saily eSIM. When you leave, switch back to your regular plan.
Do I need to uninstall Saily after my trip ends?
No. You can leave the Saily app on your phone and use it again for your next trip. The eSIM plan expires on its own and stops working after the date shown in the app. You do not have to do anything to remove it.
