The Oppo Find N3 is a book-style foldable phone with eSIM support listed for Oppo's Find series, though availability can vary by region, carrier firmware, and sales channel. This guide assumes an Oppo Find N3 running an English ColorOS 13 or ColorOS 14 build, using the cover screen for setup because it is easier to scan a QR code and follow one-handed.
For travelers, an iRoamly travel eSIM lets you prepare mobile data before a trip without swapping your physical SIM. Oppo's menu wording may vary slightly, but the expected path is Settings > Mobile network > eSIM, followed by Add eSIM.
This guide covers both installation paths: scanning the iRoamly QR code and entering the iRoamly manual details. Use QR code setup when you can show the code on another screen or print it. Use manual entry when the QR code cannot be scanned, or when you only have the SM-DP+ address and activation code.
Before You Set Up Your iRoamly eSIM
Connect the Oppo Find N3 to stable Wi-Fi before downloading the eSIM profile.
Confirm your specific Oppo Find N3 variant supports eSIM. Oppo eSIM availability can depend on region and carrier; mainland China or carrier-specific units may differ.
Keep your iRoamly QR code open on another device, or have the manual details ready: SM-DP+ Address, Activation Code, and any optional confirmation code if iRoamly provides one.
Install the eSIM 1-2 days before travel when possible, but wait to turn it on for data until you arrive at the covered destination or are about to travel.
iRoamly plan validity starts from activation. In iRoamly setup guidance, activation for travel data means selecting the eSIM for data use and connecting in the covered country or region, so avoid activating too early.
iRoamly eSIM plans may not include voice calls or SMS. Check the exact plan details before relying on calling or texting.
Do not delete the iRoamly eSIM after installation unless support tells you to. Many travel eSIM profiles cannot be reinstalled after removal.
Method 1: Install eSIM by Scanning a QR Code
1. Open Settings on the Oppo Find N3 cover screen, then tap Mobile network. You should see the ColorOS mobile network page with SIM and eSIM options.
2. Tap eSIM in Mobile network. The phone should open the eSIM management page where you can add or manage downloaded eSIM profiles.
3. Tap Add eSIM. ColorOS should start the eSIM setup flow and prepare the phone to scan a QR code.
4. Choose Scan QR code, then point the Oppo Find N3 camera at the iRoamly QR code from your purchase email or iRoamly account. Keep the QR code flat and bright until the phone recognizes it.
5. Review the detected iRoamly eSIM profile, then tap Download or Add. Keep Wi-Fi connected while the eSIM profile downloads.
6. When ColorOS finishes adding the eSIM, tap Done. If the phone asks whether to enable the new eSIM immediately, keep it off for data until you are near the covered destination unless your trip has already started.
Method 2: Install eSIM Manually
1. Open Settings, tap Mobile network, then tap eSIM. This is the same starting point used for QR setup, and it should show the eSIM management page.
2. Tap Add eSIM. ColorOS should open the add-eSIM screen again.
3. Tap Need help? or Enter details manually if it appears under the QR scanner. ColorOS manual setup normally asks for the carrier activation details instead of a camera scan.
4. Enter the iRoamly SM-DP+ Address in the matching field, then enter the Activation Code. If iRoamly provides a Confirmation Code, enter it only in the optional confirmation-code field. Do not add spaces or extra characters.
5. Tap Next, then review the iRoamly eSIM profile details. If the profile name and destination look correct, tap Download or Add.
6. Wait for the download to finish, then tap Done. Leave the eSIM installed even if you are not ready to use travel data yet.
How to Confirm Your iRoamly eSIM Is Installed
1. Go to Settings > Mobile network > eSIM. Confirm that an iRoamly or travel eSIM profile appears in the eSIM list.
2. Tap the iRoamly eSIM profile and check that the line can be switched on. If you are still at home, you can leave the eSIM off until you arrive or are about to travel.
3. After arrival in the covered destination, turn off Wi-Fi briefly and check whether mobile data loads a webpage or map through the iRoamly line.
Configure eSIM for Mobile Data
1. Open Settings > Mobile network, then tap Mobile data. You should see the available SIM and eSIM options for data service.
2. Select the iRoamly eSIM as the preferred mobile data line. Keep your primary SIM selected for calls or SMS unless your iRoamly plan explicitly includes those services.
3. Open the iRoamly eSIM profile and turn on Data roaming if your iRoamly destination instructions require roaming. Many travel eSIMs need roaming enabled to attach to partner networks.
4. Disable automatic mobile-data switching if ColorOS offers a setting that could move data back to your primary SIM. This helps avoid unwanted roaming charges on your home line.
Troubleshooting
If Add eSIM is missing, confirm your Oppo Find N3 variant supports eSIM, update ColorOS, restart the phone, and check with Oppo or your carrier. Some regional models may not expose eSIM.
If the QR code has already been used, do not delete the profile and try again. Contact iRoamly support, because many eSIM QR codes can be installed only once.
If the QR code will not scan, raise the brightness on the other screen, clean the camera lens, avoid glare, and use manual entry with the SM-DP+ address and activation code.
If manual entry fails, check each character in the SM-DP+ address and activation code. Do not include spaces before or after the values.
If the eSIM installs but shows no service, wait until you are inside the destination covered by the iRoamly plan, then turn on the eSIM and enable data roaming if required.
If mobile data still does not work, select the iRoamly eSIM for Mobile data, turn off Wi-Fi for a test, toggle airplane mode, and restart the Oppo Find N3.
If calling or SMS does not work, check your iRoamly plan details. Many travel eSIMs are data-only, so calls and texts may need your primary SIM or an internet calling app.
Conclusion
For the Oppo Find N3, QR setup is the quickest route when the iRoamly QR code is available on another screen, while manual entry is the better fallback when scanning fails or you are copying details from your iRoamly account. The important ColorOS checkpoints are Mobile network, eSIM, Add eSIM, and the manual fields for SM-DP+ Address and Activation Code.
Once the profile appears in the eSIM list, keep it installed, choose it for Mobile data when you reach the covered destination, and turn on Data roaming if the plan instructions call for it. That gives the Find N3 a clean travel-data setup without risking accidental roaming on the primary SIM.
