How to Scan an eSIM QR Code (Step-by-Step, Any Phone)
Here's how to scan an eSIM QR code on any phone: open Settings — not your regular camera app — and look for the option to add a cellular or mobile plan. Both iPhone and Android have a built-in scanner in that menu; point it at the code and the eSIM profile installs automatically. The exact wording differs by phone maker, and a few common snags (glare, single-use codes, no second device to display the code on) trip people up, so this guide walks through the full process plus the fixes.
If you've already tried scanning and the code simply won't read, skip ahead to the dedicated troubleshooting guide — this article covers the general step-by-step process.
Before You Scan: 3 Things to Check
- Connect to Wi-Fi first. Downloading an eSIM profile uses data, and you typically don't have local cellular service yet. Scan the code while still on home Wi-Fi, ideally before you leave for your trip.
- One QR code usually means one install. Most eSIM QR codes are single-use — once a profile is downloaded to a device, scanning the same code again on another phone will typically fail. If you need the eSIM on a different device, ask your provider for a fresh code rather than reusing the same image.
- Have the code ready as an image or printout, not just a link buried in an email you can't open on the phone you're installing to. This matters more than it sounds — see the second-device section below.
How to Scan an eSIM QR Code on iPhone
- Open Settings → Cellular (or Mobile Data).
- Tap Add eSIM (older iOS versions may say Add Cellular Plan).
- Choose Use QR Code.
- Allow camera access if prompted, then frame the QR code inside the on-screen box — iPhone scans it automatically, no shutter button needed.
- Tap Continue, then follow the prompts to label the plan (for example, "Travel") and set it as your data line.
Shortcut: on many iPhones, opening the regular Camera app and pointing it at the QR code also works — iPhone recognizes it as a cellular plan and shows a notification banner you can tap to jump into the same install flow. If the banner doesn't appear, use the Settings method above.
How to Scan an eSIM QR Code on Android
Wording varies by manufacturer, but the pattern is consistent: Settings → network/SIM section → add a SIM → scan a QR code.
| Phone | Path |
|---|---|
| Google Pixel | Settings → Network & internet → SIMs → tap + next to SIMs → Set up eSIM / Use downloaded SIM → scan the QR code |
| Samsung Galaxy | Settings → Connections → SIM manager → Add eSIM → Scan QR code from carrier |
| Other Android | Settings → Network & Internet (or "Connections") → SIMs / Mobile network → Add eSIM/carrier |
If your phone shows no "Add eSIM" option at all, it may not support eSIM, or eSIM may be disabled by a carrier lock — check whether your phone supports eSIM before assuming the scanner itself is broken.
Quick Fixes If the QR Code Won't Scan
Most scanning failures come down to one of these:
- Brightness and glare. Turn the screen brightness up on whatever is displaying the code, and reduce reflections.
- Framing. Back away slightly if the code is too close to focus, or zoom in on a printed copy that's too small.
- A code that's already been used. If the profile installed once before — even on a different phone — the code is now dead; this is one of the most common reasons scanning "fails" with no visible problem.
- Manual entry as a fallback. Every eSIM QR code has an underlying activation address. If scanning keeps failing, choose "Enter Details Manually" on the same Add eSIM screen — see how to activate an eSIM manually for the exact fields to fill in.
These cover most one-off glitches. If you've worked through all of them and it still won't scan, the cause is usually something more specific to your carrier or device — the eSIM QR code not scanning guide breaks those down in more depth.
Scanning From a Second Device or a Printout
The scanner needs to see the QR code through the phone's camera, which means the code can't be sitting on the screen of the exact phone you're installing it to. If the code arrived by email and you only have one phone, you have a few options:
- Open the email on a laptop, tablet, or someone else's phone, and scan it from that screen with the phone you're activating.
- Print the QR code on paper. A clear black-and-white printout scans just as well as a screen — avoid glossy paper, which reflects light back into the camera.
- Photograph the code from another device's screen ahead of time, then view that photo full-screen when scanning, if a printer isn't available.
If the QR code genuinely only exists on the same phone you need to activate — for example, it was generated or saved directly on that device — that's a narrower edge case covered in the troubleshooting guide.
Get Your eSIM Ready Before You Travel
Scanning is the last step, not the first. Before a trip, you still need a plan for the country you're visiting, sized to how much data you'll actually use. Simnity sells prepaid travel eSIM data plans you can buy online; after checkout, the QR code — plus the manual activation details as a backup — arrives by email, so you can install the eSIM before you fly and just switch on data roaming after you land.
FAQ
Do I need Wi-Fi to scan an eSIM QR code? You need an internet connection to download the eSIM profile after scanning, so Wi-Fi is the easiest option — especially since you typically don't have local cellular service yet at that point.
Can I use my regular camera app to scan an eSIM QR code? On many iPhones, yes — the Camera app can detect it and show a banner to tap. On Android this is inconsistent across brands, so the in-Settings scanner (Add eSIM → Scan QR code) is the more reliable method.
What happens if I scan the QR code twice? Most eSIM QR codes are single-use. Scanning a code that's already been installed once, on the same or a different device, will typically fail or show an error — you'll need a new code from your provider rather than reusing it.
Can I scan an eSIM QR code that's on the same phone I'm installing it to? Not directly with the camera, since a phone can't usefully photograph its own screen. See eSIM QR code not scanning for workarounds specific to this case.
My phone has no option to add an eSIM at all — what's wrong? This usually means the device doesn't support eSIM, or it's carrier-locked in a way that hides the option. Confirm compatibility first at check if your phone supports eSIM.
