Does the OPPO Reno15 support eSIM?
OPPO Reno15 eSIM compatibility
Yes, the OPPO Reno15 supports eSIM on global models released in most international markets. The standard Reno15 5G and Reno15 Pro variants both include eSIM functionality, allowing you to activate a digital carrier plan without a physical SIM card. The device offers dual-SIM capability, so you can use one eSIM alongside one nano-SIM card simultaneously—ideal for keeping your home number active while adding a data plan.
Regional variants and dual-SIM configuration
The OPPO Reno15 Series 5G models sold in Europe, Asia-Pacific, and Middle East regions typically include eSIM support. Some regional variants—particularly those sold exclusively in specific local markets—may ship with dual nano-SIM slots instead. If you purchased your Reno15 from a carrier or in a market where eSIM adoption is limited, verify your device's eSIM capability by opening Settings > Mobile network > SIM card management. If you see an "Add eSIM" or "Download eSIM" option, your device supports it. The Reno15 does not support dual eSIM configurations; you must use one eSIM paired with one physical nano-SIM.
How to set up an eSIM on the OPPO Reno15
Set up an eSIM in Settings
Installing an eSIM on the OPPO Reno15 takes about 60 seconds once you have your QR code from your carrier or eSIM provider. Make sure you're connected to Wi-Fi before you begin, because the device needs to download the eSIM profile.
- Open Settings, then tap Mobile network or SIM card management.
- Tap Add eSIM or Download eSIM.
- Choose Scan QR code and point your camera at the QR code provided by your carrier or eSIM service.
- Tap Confirm to download the eSIM profile; this usually completes within 30–60 seconds.
- Once installed, label your eSIM line (e.g., "Travel Data" or "Work") so you can easily identify it.
- Go to Mobile network > SIM card management to set which line you want to use for mobile data, calls, and SMS.
Labelling and managing two lines
After you activate your eSIM, the OPPO Reno15 will prompt you to assign a default line for data and another for calls. You can change these defaults anytime in SIM card management, which is useful when traveling—set your eSIM as the data line and keep your home nano-SIM active for incoming calls and text messages.
Using a travel eSIM on the OPPO Reno15
A travel eSIM is the simplest way to get mobile data abroad without paying roaming fees from your home carrier. You install the eSIM before you fly, and as soon as you land, your Reno15 connects to a local network. You keep your primary number active on the nano-SIM slot for calls and two-factor authentication codes, while the eSIM handles all data.
Choose a regional or country-specific plan that matches your itinerary, download the eSIM profile at home over Wi-Fi, and switch on the eSIM data line once you arrive. You'll find prepaid data plans for the Reno15 5G in over 200 destinations when you browse eSIM plans by region or country. Because the Reno15 supports both 4G and 5G bands globally, you'll get fast speeds in most markets, including coverage across Europe, Asia, and the Americas—just confirm the plan matches the network bands your destination uses.
Tips and troubleshooting
Turn on data roaming for the eSIM line
After installing a travel eSIM, go to Settings > Mobile network, select your eSIM line, and toggle Data roaming on. This sounds counterintuitive, but your eSIM plan is a roaming service to the device, so data roaming must be enabled for it to work. Your home nano-SIM can stay off for data roaming to avoid surprise charges.
Keep your home SIM active for calls and authentication
Leave your primary nano-SIM enabled for calls and SMS, but turn off mobile data for that line. This way, you'll still receive verification codes and phone calls on your usual number, while the eSIM handles all internet traffic. Check the default settings in SIM card management to confirm your eSIM is set as the data line.
What to do if the QR code won't scan
If the camera won't read your QR code, increase screen brightness on the device displaying the code, or try entering the activation details manually. Tap Enter activation code instead of scanning, then type the SM-DP+ address and activation code exactly as provided. If the eSIM still won't install, restart the Reno15 and confirm you're connected to Wi-Fi. For persistent issues, eSIM setup help can walk you through carrier-specific steps, or you can check another device's eSIM compatibility if you're working with a secondary phone.
