Open the Google Play Store on your OPPO, search for Saily and tap Install. Open the app, sign in with Google, Apple or Microsoft, and tap Install eSIM.
The catch: the app needs Android 10 or later, and the eSIM only works if your OPPO model supports eSIM and isn’t carrier-locked.
OPPO phones run Android, so you get Saily from the Google Play Store like any other app. Saily has no OPPO-specific guide, so the eSIM steps below are its general Android steps. Your OPPO’s menu names may differ.
Before you download
- Android 10 or later. That’s the minimum Saily lists for the app.
- A Google Play account and an internet connection.
- eSIM support. Check your exact OPPO model on Saily’s eSIM-compatible devices list, and make sure it isn’t carrier-locked.
Download the Saily app
- Open the Google Play Store on your OPPO.
- Use the search bar to search for Saily.
- Tap Install.
- When it finishes, open the app.
Sign in or create an account
Saily has no password. You sign in with your Google, Apple or Microsoft account, and that creates your account the first time. Your account information is saved in the cloud, so you can sign in again later on a new install.
Keep the app up to date
Saily’s minimum supported app version is 3.23. Older versions aren’t supported.
- In the Saily app, tap the profile or menu icon and scroll to the bottom to see your version.
- In Google Play, open the Saily listing and tap About this app to see the latest version.
- Tap Update if one is available.
Buy a plan and install the eSIM
- In the app, tap Explore plans, select your destination, tap Continue and check out. Use DEAL15 under Got a coupon? for 15% off.
- Connect to Wi-Fi and tap Install eSIM.
- Select the device and tap Continue, then Start eSIM install.
- Tap Allow and wait a few seconds without closing the app.
- Name the eSIM if you like, then pick your SIM for calls, messages and mobile data.
- Go back to the Saily app, tap Continue and follow its steps to turn on the line, enable roaming and use Saily for data.
Check the eSIM in your OPPO settings
After the install, the Saily eSIM should appear in your phone’s SIM settings. Saily’s Android guide shows two paths: Settings → Connections → SIM manager, or Settings → Network & internet → SIMs. Saily notes that non-Samsung Android phones may use different names, so look for the SIM or mobile network section on your OPPO.
There, make sure the Saily eSIM is on, data roaming is on for it, and it’s selected for mobile data. The plan activates automatically when you arrive at your destination and connect to a supported network.
If the app gives you trouble
Updating to the latest version is often the quickest fix when a feature isn’t working.
Uninstall Saily, install it again from Google Play and sign in with the same account. See how to reinstall the Saily app.
Check your connection, update Android, turn off any VPN and restart the phone, then try again. The manual setup details are under View instructions in the app.
Live chat runs 24/7 inside the app: open the Help tab and tap Chat with us. See how to contact Saily support.
FAQ
Is the Saily app on OPPO the same as on other Android phones?
Yes. You get it from the Google Play Store, and Saily’s Android guide applies. Only your phone’s settings menus may look different.
Do I need the app to use Saily eSIM?
Saily’s install guides ask you to have the app installed, and live chat support is only in the app.
My OPPO doesn’t support eSIM. Can I still use Saily?
Saily suggests a physical eSIM.me card that takes eSIM profiles. Contact Saily support to get the QR code for setup.
What if I forget which account I used?
Sign in with the same Google, Apple or Microsoft account as before. Saily keeps your account information in the cloud, so it’s there when you sign in.
