If you just got an OPPO phone and heard about eSIM, you’re probably wondering what it is, whether your device supports it, and how to get it set up. Don’t worry — this guide walks you through everything in plain language. No jargon, no complicated tech speak. Just clear steps that actually work.
eSIM (embedded SIM) is a digital SIM technology that allows you to activate a mobile network without inserting a physical SIM card. Many modern smartphones, including selected models from OPPO, now support eSIM for greater flexibility and convenience.
How to install eSIM on Android OPPO started introducing eSIM support in its premium devices like the OPPO Find X3 Pro, OPPO Find X5 Pro, and newer flagship models. With eSIM, users can store multiple network profiles on one device and switch between them easily, which is especially useful for travelers or people managing work and personal numbers.
What Is an eSIM, and Why Should You Care?
An eSIM (embedded SIM) is a digital version of the traditional SIM card. Instead of a small plastic chip you slot into your phone, the eSIM is built right into the device. You activate it by scanning a QR code or entering a code from your carrier — no physical swapping needed.
For OPPO users, this is a big deal. Imagine traveling abroad and switching to a local data plan without hunting down a SIM card shop. Or keeping a personal number and a work number on the same phone without carrying two devices. That’s the kind of flexibility eSIM gives you.
Does Your OPPO Phone Support eSIM?
Not every OPPO phone has eSIM support. Before you go any further, check whether your specific model is compatible.
OPPO models that generally support eSIM include:
- OPPO Find X3 Pro
- OPPO Find X5 / X5 Pro
- OPPO Find X6 / X6 Pro
- OPPO Reno 8 Pro (select markets)
- OPPO A93 5G (some regions)
- OnePlus phones (which run on OPPO’s parent company ColorOS ecosystem in some variants)
Quick check: Go to Settings → About Phone → SIM Card Status. If you see an “eSIM” option, your device supports it.
Also, keep in mind that eSIM availability depends on your country and carrier. Even if your phone supports it, your network provider needs to offer eSIM activation. In India, for example, Jio, Airtel, and Vi all support eSIM on compatible devices.
What You’ll Need Before You Start
Before diving into the installation steps, get these things ready:
- A compatible OPPO phone (checked above)
- An active internet connection (Wi-Fi is preferred during setup)
- A QR code or activation code from your carrier — your carrier provides this when you request eSIM activation
- Your account details with your carrier (you might need to verify your identity)
- A backup of your contacts, just to be safe
If you haven’t requested eSIM activation from your carrier yet, call their customer support or visit their website. They’ll either email you a QR code or give you an activation code.
How to Install eSIM on Android OPPO — Step by Step
Method 1: Using a QR Code (Most Common Method)
This is the standard way most carriers deliver eSIM profiles.
Step 1: Open Settings.s On your OPPO phone, open the Settings app. You’ll find it in your app drawer or by swiping down and tapping the gear icon.
Step 2: Go to SIM Card & Mobile Data. Scroll down and tap on “SIM Card & Mobile Data” (on some ColorOS versions, this may appear as “Mobile Network” or “Connections”).
Step 3: Add eSIM.eSIM. You’ll see an option that says “Add eSIM” or “Add Mobile Plan”. Tap it.
Step 4: Scan the Q.R Code. Your phone’s camera will open. Hold your phone up to the QR code your carrier sent you — either printed on a letter or shown on another screen. The phone will detect it automatically.
Pro tip: If you’re trying to scan a QR code that’s on the same phone (like in an email), use another device to display the QR code, then scan it with your OPPO.
Step 5: Confirm and Activate After scanning, your phone will ask you to confirm the details — the carrier name, plan type, and phone number. Review them and tap “Add” or “Confirm”.
Step 6: Wait for the installation. The download usually takes 30 seconds to 2 minutes. Keep your Wi-Fi on. Once done, you’ll see a success message, and the new plan will appear under your SIM settings.
Step 7: Set Preferences You can now choose which SIM (physical or eSIM) handles calls, texts, and data. Go back to SIM Card & Mobile Data and set your preferences.
Method 2: Using an Activation Code (Manual Entry)
Sometimes carriers give you a manual code instead of a QR code — especially if you’re activating through a customer service chat or the carrier’s app.
Step 1 to Step 3: Same as above — go to Settings → SIM Card & Mobile Data → Add eSIM.
Step 4: Choose Manual Entry.y Instead of scanning, look for an option that says “Enter Activation Code” or “Add Manually”. Tap it.
Step 5: Type i.n the Code. Enter the activation code exactly as provided. These codes are usually long alphanumeric strings — double-check every character.
Step 6: Confirm and Activate Tap “Next” or “Activate” and follow the on-screen prompts. The rest of the process mirrors Method 1.
Method 3: Via Your Carrier’s App
Some carriers — like Airtel or Jio in India — have their own apps that make eSIM setup even easier.
For example, with Airtel:
- Open the Airtel Thanks app
- Go to your account, select “Get eSIM.”
- Verify your identity via OTP
- The app will push the eSIM profile directly to your phone
With Jio:
- SMS “SIMCHG <your 19-digit eSIM number>” to 1800 889 9999
- You’ll receive a QR code via SMS or email
- Scan it using the steps in Method 1
The exact flow varies by carrier, but most apps guide you through it smoothly.
Managing Your eSIM After Installation
Once your eSIM is active, you have full control over how it works alongside your physical SIM.
Switching between SIMs: Go to Settings → SIM Card & Mobile Data. You can set which SIM is used for:
- Calls
- SMS
- Mobile data
Disabling the eSIM temporarily: If you want to turn off your eSIM without deleting it, tap on the eSIM in your SIM settings and toggle it off.
Deleting the eSIM: To remove an eSIM profile completely, go to Settings → SIM Card & Mobile Data → [eSIM name] → Delete Some. Note: Some carriers only allow a limited number of eSIM transfers per year, so only delete if you’re sure.
Pros and Cons of Using eSIM on OPPO
âś… Pros
Convenience when traveling: No need to buy or swap physical SIMs. If you’re going to Singapore for a week, just buy a local eSIM plan online and activate it in minutes. No airport SIM kiosks, no tiny SIM ejector tool required.
Dual SIM without two physical cards.s You can run a personal number and a work number on one phone. OPPO’s dual SIM support with eSIM means one slot is free for a physical card too.
Harder to lose.e A physical SIM can get lost, damaged, or stolen. Since eSIM is embedded, you don’t have to worry about that.
Faster setforFor new plan activations, eSIM is almost instant. No waiting for a card to arrive in the mail.
Environmentally friendlier, with less plastic waste from SIM cards.
❌ Cons
Not universally supported. Many carriers, especially in smaller cities or rural areas, haven’t rolled out eSIM yet. If your carrier doesn’t support it, you’re stuck with a physical SIM.
Limited transfers.s Some carriers cap how many times you can transfer your eSIM to a new device per year. If you switch phones frequently, this can be frustrating.
Device-locked issues: uses. If your OPPO is carrier-locked, you may only be able to use eSIM with that specific carrier.
Harder troubleshoots, but Physical SIM issues are easy to diagnose — just swap the card. With eSIM, problems can be harder to pin down and usually require calling your carrier.
Not all OPPO models support eeSIM. Readit. Budget OPPO models often skip eSIM support entirely.
Common Problems and How to Fix Them
“eSIM option not showing in Settings.” Your phone might not support eSIM, or the feature might not be enabled in your region. Check OPPO’s official site for your model’s specs, or contact your carrier.
QR code scanning.g Make sure the QR code isn’t blurry or too small. Increase the brightness of the screen displaying the code. Try scanning in good lighting.
Activation stuck or failed. Check your internet connection. Restart the process after a few minutes. If it keeps failing, call your carrier — sometimes their servers have delays.
eSIM shows “No Service.e” Wait a few minutes after activation — sometimes it takes time for the network to register. If the issue persists, toggle airplane mode on and off, or restart your phone.
Wrong number or plan details.ls Contact your carrier immediately. Don’t delete the eSIM yet — your carrier might be able to fix the profile remotely.
Practical Example: Setting Up an eSIM on OPPO Find X5 with Airtel India
Here’s a real-world walkthrough:
Priya has an OPPO Find X5 and wants to add an Airtel eSIM as her second number for work.
- She opens the Airtel Thanks app on her phone and logs into her Airtel account.
- Under her account section, she selects “Get eSIM”.
- Airtel sends an OTP to verify her identity.
- After verification, the app asks her to confirm her device’s EID number (found in Settings → About Phone → SIM Card Status → EID).
- Airtel pushes the eSIM profile to her OPPO. A notification pops up asking her to add the eSIM.
- She taps the notification, confirms the plan details, and the eSIM downloads in about 90 seconds.
- She then goes to Settings → SIM Card & Mobile Data and sets:
- SIM 1 (personal Jio physical card) → for calls
- SIM 2 (Airtel eSIM) → for data
- Done. Now she has two numbers, no extra SIM card slot used.
