Does the OPPO Reno15 Fs support eSIM?
OPPO Reno15 Fs eSIM compatibility
Yes, the OPPO Reno15 Fs supports eSIM. The device features a Nano-SIM + eSIM configuration, which means you can use one physical SIM card alongside one eSIM profile simultaneously. This dual-SIM setup gives you flexibility to maintain two separate phone numbers or data plans on a single device—ideal if you want to keep your home number active while adding a local or travel data plan.
The OPPO Reno15 Fs is available in 5G variants, and the eSIM functionality works across supported networks that offer eSIM services. You'll want to confirm that your carrier supports eSIM activation before purchasing a plan. The device's eSIM capability applies to all color options, including the twilight blue finish, and works independently of your choice of storage or RAM configuration.
Dual SIM on the OPPO Reno15 Fs
You can run both your physical Nano-SIM and your eSIM at the same time. This lets you separate work and personal lines, or keep your regular number for calls and texts while using an eSIM exclusively for data. The phone manages both connections through ColorOS settings, where you can assign which SIM handles mobile data, calls, and messages.
How to set up an eSIM on the OPPO Reno15 Fs
Set up an eSIM in Settings
Activating an eSIM on your OPPO Reno15 Fs 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 start, because the phone needs to download your eSIM profile during setup.
- Open Settings and tap Mobile Network (or SIM Card & Mobile Data, depending on your ColorOS version).
- Tap SIM Card Management or Add eSIM.
- Select Add Mobile Plan or Add eSIM Profile.
- Tap Scan QR Code and point your camera at the QR code provided by your eSIM carrier.
- Confirm the plan details and tap Add or Download.
- Wait for the eSIM to activate—this usually takes 30–60 seconds.
- Label your new line (for example, "Travel Data" or "Work") so you can easily identify it.
- Choose which SIM you want to use for mobile data, calls, and SMS in the SIM settings.
Scanning your eSIM QR code
Your eSIM provider will email or display a QR code after you purchase a plan. Keep that code accessible on another device or print it out, because you can't scan a QR code that's displayed on the same phone you're setting up. If you only have one device, most providers also offer a manual activation option where you enter an activation code or SM-DP+ address instead of scanning.
Using a travel eSIM on the OPPO Reno15 Fs
Get data abroad without roaming fees
Travel eSIMs are the simplest way to stay connected when you're outside your home country. Instead of paying international roaming charges on your main SIM or hunting for a local SIM card shop at the airport, you can install a data eSIM on your OPPO Reno15 Fs before you leave. You'll have mobile data as soon as you land, and your physical SIM stays in place so you can still receive calls and texts on your regular number.
Install your travel eSIM while you're still at home and connected to Wi-Fi. Most eSIM plans activate automatically when you arrive in the destination country and your phone connects to the local network, though some let you choose an activation date. You can browse eSIM plans by destination to compare coverage and data allowances.
Managing two SIMs while traveling
Once your travel eSIM is active, go into Settings > Mobile Network and set the eSIM as your default for Mobile Data. Leave your home physical SIM enabled for calls and SMS so you can still receive verification codes and important calls. You can toggle data roaming on or off for each SIM independently, which prevents accidental roaming charges on your home line while you're using the eSIM for data.
Tips & troubleshooting
Turn on data roaming for your eSIM line
Even though your eSIM is a local or regional plan, your OPPO Reno15 Fs still treats it as a secondary line. Go to Settings > Mobile Network, select your eSIM, and make sure Data Roaming is turned on. Without this, your eSIM won't connect to the network. This is the most common reason an eSIM appears installed but won't deliver data.
Keep your home SIM active for calls and two-factor authentication
Don't remove or disable your physical SIM while traveling. Leave it active so you can receive calls and SMS-based security codes from your bank or email provider. Just make sure mobile data is turned off for that SIM to avoid roaming charges. Your OPPO Reno15 Fs will route all data through the eSIM, and calls and texts through whichever SIM you designate.
Fix an eSIM that won't activate
If your eSIM gets stuck during installation, restart your phone and try again. Make sure you're on a stable Wi-Fi connection—mobile data from your physical SIM won't work for eSIM downloads. If the QR code won't scan, check that your camera lens is clean and you have good lighting. You can also ask your provider for manual activation details and enter the SM-DP+ address and activation code by hand under Enter Code Manually or similar option in the eSIM setup flow.
If you need to switch devices or remove an eSIM, go to Settings > Mobile Network > SIM Card Management, tap the eSIM you want to delete, and select Erase eSIM. Be aware that some eSIM plans are single-use; deleting the profile may mean you need to purchase a new plan. If you're unsure about compatibility with another device, you can check another device's eSIM compatibility before making the switch.
