How to Activate an eSIM on Android: Step-by-Step

Activate an eSIM on Android in minutes the QR and manual methods, exact steps for Samsung and Pixel, how to turn on data and roaming, and what to do if it won't connect.

Here's the thing most "my eSIM won't work" complaints have in common: the eSIM was fine. A single setting was off usually the wrong data line, or roaming left switched off. An eSIM itself is nothing exotic; it's a SIM baked into your phone's software, with no card to slot in and nothing to misplace. You download a plan and you're on. So the goal of this guide isn't just to install one it's to get you genuinely online on your Android in a couple of minutes, and to show you where the process trips people up, so it doesn't trip you.

Before You Start: What You Need

Three quick checks head off almost every snag later:

• An eSIM-compatible and unlocked phone. Most recent Samsung Galaxy, Google Pixel, Motorola, and Oppo models take eSIM without fuss but the one people forget is the lock: a phone still tied to a carrier can reject an eSIM from anyone else. Easy test dial *#06#, and if an EID number appears, you're set. Or check the list of compatible devices.
• The latest Android version. Menu names and eSIM features keep moving with updates, so clear any pending OS update first.
• A stable Wi-Fi connection. You need the internet to pull down the eSIM profile, and Wi-Fi is the one to trust which is exactly why installing before you fly, while you're still connected, beats scrambling at the airport.

With that done, grab your eSIM plan: choose your destination, pay in a few taps, and the QR code plus a manual code for backup arrives by email right away.

How to Activate an eSIM on Android (QR Code)

The QR scan is the quick route. Wording differs a touch between phones, but the path holds steady: open your SIM settings, add an eSIM, scan.

1. Open Settings → Network & Internet → SIMs (or Mobile Network).
2. Tap Add eSIM, Add SIM, or the + beside Mobile Network.
3. If you're asked "Don't have a SIM card?" or "Download a SIM instead?", tap Next.
4. Choose Scan QR code and aim the camera at the code from your email.
5. Enter the confirmation code if asked, then confirm the download.
6. Give it a moment to install.

Installed but hold on, that's not the same as connected. Two quick toggles finish the job; they're in Turn It On below.

Manual Activation (SM-DP+ Address)

QR codes are fussier than they look dim light, a scuffed lens, or a code that only ever showed up as text. When the scan won't take, the manual route gets you to the exact same place.

1. In your eSIM email, find the SM-DP+ Address and Activation Code.
2. Go to Settings → Network & Internet → SIMs → Add eSIM.
3. At the scan prompt, tap Enter it manually (it sometimes hides under Need help? or Enter code manually).
4. Type in the SM-DP+ Address and Activation Code, then confirm.
5. Let it install, and move on to the toggles below.

Samsung Galaxy vs Google Pixel: Where the Menus Live

Samsung and Pixel cover most Android phones between them, and their menus don't agree Samsung's especially shifted with recent One UI updates, which is why so many how-to screenshots online quietly lead you astray. Here's where the setting actually lives on each.

On a Samsung Galaxy (recent One UI): Settings → Connections → SIM manager → Add eSIM → Scan QR code (or Enter activation code).

On a Google Pixel: Settings → Network & internet → SIMs → + Add SIM / Download a SIM instead? → Next → scan your QR code.

Labels drift by model and Android version, so lean on these as the reliable route rather than exact wording.

Turn It On: Data, Roaming & APN

Back to that opening point this is the step that separates "installed" from "online," and the one people skip. Two toggles do most of the work:

• Switch the eSIM line on and make it your data SIM. In your SIM settings, enable the new eSIM and pick it for mobile data.
• Data Roaming on for the eSIM, off for your home SIM. It reads backwards, but a travel eSIM reaches you through a local partner network abroad, so it needs roaming enabled to connect at all. Turn your home SIM's roaming off in the same breath, and that's what keeps your usual carrier from billing you on the quiet. This pair of settings is the single biggest source of both "no internet" and "why is my bill huge" stories.

Most eSIMs handle their APN the setting that lets data actually move by themselves. If everything looks right but nothing loads, key in the APN from your activation email manually. 

Dual SIM: Keep Your Number + Travel Data

There's no trade-off between your usual number and travel data. Nearly every eSIM-capable Android runs dual SIM, so your home SIM stays live for calls, texts, and the two-factor codes you can't miss, while the eSIM quietly carries the data. Set the eSIM as your data line, keep your number for calls, and as above switch the home SIM's roaming off. And if plans change, nothing's permanent: you can disable or remove the eSIM in settings whenever.

Moving Your eSIM to a New Phone

Getting a new handset? On newer Androids Android 14 and One UI 6 onward, and Pixel 6 and up the setup wizard on the new phone can often bring an eSIM across during first-time setup. It doesn't work for every profile, mind. If that transfer option never shows, the fix is painless: reinstall the eSIM on the new phone from your provider's app or email.

Troubleshooting: If Your eSIM Won't Activate

Nearly every hiccup traces to one of a few causes. Work down the list:

Problem	Likely cause	Fix
QR code won't scan	Poor lighting, or the code was already used	Use the manual SM-DP+ method instead
Installed, but no internet	Data roaming off for the eSIM, wrong data SIM selected, or APN missing	Turn Data Roaming on for the eSIM, set it as the data SIM, add the APN if needed
"No service" / won't connect	Not yet at your destination, phone is carrier-locked, or the line isn't enabled	Confirm you've arrived/activated, check the phone is unlocked, switch the eSIM line on
No "Add eSIM" option at all	Phone isn't eSIM-compatible, or the OS is out of date	Dial *#06# to check for an EID; update Android
Looks right, still nothing	Temporary network hiccup	Toggle Airplane mode on/off, or restart the phone

FAQs

1. How do I activate an eSIM on Android?

 Open Settings → Network & Internet → SIMs → Add eSIM, scan the QR code from your provider (or enter the SM-DP+ details by hand), then switch the eSIM line on and set it as your data SIM. On most phones you're online within a couple of minutes.

2. Which Android phones support eSIM? 

Recent Samsung Galaxy (S, Z Flip/Fold, and Note models), Google Pixel (3 and newer), and plenty of Motorola (Razr, Edge) and Oppo phones do but not every Android does. Fastest check: dial *#06# and look for an EID, or check your device here.

3. Do I need Wi-Fi to set up an eSIM?

 Yes downloading the profile needs an internet connection, and Wi-Fi is the most reliable. It's the reason installing before you travel, while you're still connected, is the smart move.

4. Can I install my eSIM now and activate it when I arrive?

 Usually, yes. A lot of travel eSIMs install over Wi-Fi before your trip, then start connecting once you land and reach the local network.

5. Why won't my eSIM connect after installing?

 Nine times out of ten it's one of three things: data roaming is off for the eSIM, the eSIM isn't set as your data SIM, or the APN needs entering. Start there (the troubleshooting table above walks through it).

6. Can I use an eSIM and a physical SIM at the same time? 

Yes. Most eSIM-capable Androids are dual-SIM, so you keep your home number for calls and texts and let the eSIM handle data.

7. Can I move my eSIM to a new phone?

 On newer Androids the setup wizard can sometimes carry it over during setup; if not, just reinstall on the new phone from the app or your email.

Get Your eSIM

That's the whole thing check compatibility, install by QR or manual code, flip on data and roaming, and you're connected. Pick your eSIM plan for wherever you're headed, or download the AirHub app to buy and manage it all from your phone.
