The Oppo Find N3 Flip supports eSIM on supported carriers and regions, with OPPO noting that availability depends on the carrier and that some regional models may differ. This guide assumes an Oppo Find N3 Flip running ColorOS 13.2 or a later ColorOS build with similar Settings labels.
Travelers can install an iRoamly travel eSIM before departure so the eSIM profile is ready on the phone, then turn it on for data after arriving in the covered country or region. The Find N3 Flip menu names may vary slightly by software version, but the usual path is through Settings, Mobile network, and eSIM.
The steps below cover both supported installation paths: scanning the iRoamly QR code and entering the manual eSIM details. Manual entry is useful if the QR code is on the same phone, the camera cannot scan it clearly, or you are copying details from your iRoamly account or email.
Before You Set Up Your iRoamly eSIM
Connect the Oppo Find N3 Flip to stable Wi-Fi before downloading the eSIM profile.
Confirm your Find N3 Flip model supports eSIM in your region and with your carrier. OPPO lists eSIM support as carrier-dependent.
Keep your iRoamly QR code available on another screen or printed page, or keep the manual details ready: SM-DP+ Address, Activation Code, and any optional confirmation code if supplied.
Do not delete the iRoamly eSIM after installing it unless iRoamly Support tells you to. Many eSIM profiles cannot simply be reinstalled after removal.
Install the eSIM 1-2 days before travel when possible, but wait to use it for mobile data until you are in the covered destination.
iRoamly eSIM plan validity starts from activation. For travel data plans, activation is typically tied to enabling the eSIM for data and connecting in the covered destination, so check the specific plan details in your iRoamly order.
iRoamly plans may be data-only. Voice calls and SMS vary by plan, so do not assume they are included.
Method 1: Install eSIM by Scanning a QR Code
Open Settings on the Oppo Find N3 Flip, then tap Mobile network.
You should see the ColorOS mobile network page with SIM and eSIM options.
Tap eSIM on the Mobile network screen.
The phone should open the eSIM management page. If you do not see eSIM, your region, carrier firmware, or model variant may not support eSIM.
Tap Add eSIM.
ColorOS should start the eSIM setup flow and ask how you want to add the mobile plan.
Choose Scan QR code.
The camera scanner should open. Keep the phone connected to Wi-Fi during this step.
Point the camera at the iRoamly QR code, then keep the full code inside the frame until the phone recognizes it.
The phone should read the QR code and show an iRoamly eSIM profile ready to download. Use a placeholder QR only in screenshots; never share a real QR code publicly.
Tap Download or Add, then wait while ColorOS downloads the iRoamly eSIM profile.
The screen should show download progress and then a completion message when the eSIM has been added.
Method 2: Install eSIM Manually
Open Settings on the Oppo Find N3 Flip, then tap Mobile network.
This is the same starting screen used for QR-code setup.
Tap eSIM on the Mobile network screen.
The eSIM management page should open.
Tap Add eSIM.
ColorOS should display the eSIM setup choices.
Tap Enter details manually or Enter activation code.
The manual-entry page should appear. On this Android/ColorOS-style flow, use the separate fields supplied by iRoamly: SM-DP+ Address, Activation Code, and Confirmation Code only if iRoamly provides one.
Enter the iRoamly SM-DP+ Address and Activation Code, leave Confirmation Code blank unless iRoamly provides one, then tap Next.
The phone should validate the details over Wi-Fi. Check every character before continuing because an incorrect address or activation code can stop the download.
Tap Download or Add, then wait for the iRoamly eSIM profile to finish installing.
When the download completes, ColorOS should return to the eSIM list or show a confirmation screen.
How to Confirm Your iRoamly eSIM Is Installed
Open Settings, tap Mobile network, then tap eSIM.
The installed iRoamly eSIM should appear in the eSIM list. It may show as a carrier profile name first; rename it to iRoamly if ColorOS offers a label option.
Tap the installed iRoamly eSIM profile and confirm the line is turned on.
You should see the eSIM profile details, including an on/off switch and options for data or roaming settings.
Configure eSIM for Mobile Data
Go to Settings, tap Mobile network, then tap Mobile data.
You should see the preferred data SIM options. Select the iRoamly eSIM for mobile data when you are ready to use the travel plan.
Open the iRoamly eSIM profile and turn on Data roaming if your destination plan or iRoamly instructions require it.
After arrival, turn off Wi-Fi and open a webpage or app to test the iRoamly data connection. If your primary SIM is still active, check that automatic data switching does not move data back to your home line.
Troubleshooting
Add eSIM is missing: confirm the phone is an eSIM-capable Oppo Find N3 Flip variant, update ColorOS, and check whether your carrier or region supports eSIM on this model.
The QR code will not scan: increase screen brightness on the device showing the QR code, clean the camera lens, keep the full code inside the frame, or use manual entry instead.
The QR code was already used: do not delete and retry repeatedly. Contact iRoamly Support because many eSIM QR codes can be installed only once.
Manual entry fails: compare the SM-DP+ Address and Activation Code with the iRoamly order details. Do not add spaces unless the code specifically includes them.
The eSIM is installed but there is no data: select the iRoamly eSIM for mobile data, enable data roaming if required, turn off Wi-Fi for testing, and make sure you are inside the covered destination.
Activation is pending: keep the phone connected to Wi-Fi during installation, then test again after arriving in the covered country or region. Some travel eSIMs cannot connect to a supported network before arrival.
Calls or SMS do not work: check the exact iRoamly plan. Many travel eSIM plans are data-only and do not include voice or text service.
Conclusion
Once your iRoamly eSIM has been installed, it will remain available on your Oppo Find N3 Flip until your travel plan becomes active. When you're in a supported destination, you can start using mobile data without searching for a local SIM card or changing your existing SIM setup.
With reliable internet access for navigation, messaging, travel planning, and other everyday tasks, your travel eSIM helps you stay connected wherever your journey takes you. Keeping your physical SIM in place also makes it easy to continue using your regular number whenever needed.
