To install an eSIM on iPhone, open Settings → Cellular → Add eSIM, then scan the QR code or enter details manually; activation takes under two minutes. Works on iPhone XS/XR and newer. Your Simbye eSIM downloads instantly, doesn't auto-activate, and can be installed at home over Wi-Fi before you travel — plans start at $3.
Fumbling with a tiny plastic SIM card and hunting for a paperclip at the airport is officially outdated. With an eSIM, you download your travel data plan before you even pack your bags, then activate it the moment you land. No store visit, no shipping, no swapping cards.
This guide shows you exactly how to install an eSIM on your iPhone, step by step. There are two methods — scanning a QR code (the fast way) and entering the activation details manually. Both take under two minutes.
Which iPhones support eSIM?
Apple introduced eSIM support in 2018. Every iPhone released since then can install and run an eSIM. If you have one of these models, you're good to go:
- iPhone XS, XS Max, XR — 1 eSIM + 1 physical SIM
- iPhone 11, 11 Pro, 11 Pro Max — 1 eSIM + 1 physical SIM
- iPhone SE (2nd & 3rd gen) — 1 eSIM + 1 physical SIM (3rd gen supports dual eSIM)
- iPhone 12 series — 1 eSIM + 1 physical SIM
- iPhone 13 series — dual eSIM + 1 physical SIM
- iPhone 14, 15, 16, 17 series — dual eSIM (US models are eSIM-only, with no physical SIM tray)
Two exceptions: iPhones bought in mainland China do not support eSIM (except the iPhone Air), and Hong Kong and Macao models have limited eSIM support. Everywhere else, eSIM works out of the box.
Before you start, check three things: your iPhone is carrier-unlocked (Settings → General → About → look for "No SIM restrictions"), you're on a Wi-Fi or mobile data connection to download the profile, and you're running iOS 12.1 or later. The latest iOS version always gives the smoothest experience.
Method 1: Install an eSIM by scanning a QR code
This is the fastest way. You'll need your Simbye QR code, which arrives by email right after purchase. Have it open on a second screen — a computer, tablet, or printout — so your iPhone's camera can scan it.
- Open the Settings app on your iPhone.
- Tap Cellular (or Mobile Data, depending on your region).
- Tap Add eSIM.
- Select Use QR Code.
- Point your camera at the Simbye QR code and let it scan.
- Tap Continue to confirm, then wait a few seconds for the profile to download.
- Tap Done when the installation completes.
That's it — the eSIM is now installed on your iPhone. Skip ahead to "Label your lines and set a default" below.
On iOS 17.4 or later? You can long-press the QR code image inside your email and choose "Add eSIM" directly — no need to open the camera or have a second screen.
Method 2: Install an eSIM with manual entry
No second screen to scan from? You can type the details in by hand. Your Simbye confirmation email lists an SM-DP+ address and an activation code — these are the two values you'll need.
- Open Settings → Cellular → Add eSIM.
- Select Use QR Code, then tap Enter Details Manually at the bottom of the screen.
- In the SM-DP+ Address field, type the address from your email (it looks like
consumer.example.com). - In the Activation Code field, type the activation code exactly as shown.
- Leave the Confirmation Code field blank unless your email provides one.
- Tap Next, then Continue, and wait for the profile to download.
- Tap Done.
Manual entry installs exactly the same eSIM as the QR method — it's just a different way to hand your iPhone the same information.
Label your lines and set a default
Once the eSIM is installed, your iPhone walks you through a quick setup so it knows which line to use for what. This is where Dual SIM shines: you keep your home number for calls and texts while your Simbye eSIM handles data.
- Tap the > arrow next to your new eSIM and label it "Simbye" (or pick a preset). A clear label saves confusion later.
- Set Default Line to your primary home number, then tap Continue.
- Keep iMessage & FaceTime on your primary line, then tap Continue.
- For Mobile Data, select your Simbye eSIM label.
Important: Turn off "Allow Mobile Data Switching." This stops your iPhone from quietly falling back to your home plan and racking up roaming charges from your regular carrier.
Enable data roaming for your travel line
Here's the step travelers miss most often. A travel eSIM connects to local networks abroad, and iOS treats that as roaming — so the Data Roaming toggle must be on for the Simbye line, or you'll have no internet even though the eSIM is installed correctly.
Don't worry: turning on Data Roaming for your Simbye line costs nothing extra. Your plan is fully prepaid, and roaming is simply how your iPhone uses a foreign network. It does not enable expensive roaming on your home carrier — that's a separate line.
- Go to Settings → Cellular and tap your Simbye line.
- Make sure the line is toggled On.
- Tap Data Roaming and switch it On.
You should connect to a local network within seconds of landing. That's it — you're online.
Travel tip: Install your eSIM at home over Wi-Fi before your trip. Simbye eSIMs don't auto-activate, so the validity period only starts when you turn on the line and roaming at your destination. Setting up in advance means no scrambling for airport Wi-Fi, and if anything looks off, support can help before you leave.
Common install errors and how to fix them
Most installs are flawless, but if something goes wrong, this table covers the issues we see most and the quickest fix for each.
| Problem | Likely cause | Fix |
|---|---|---|
| QR code won't scan | Low screen brightness or shaky hands | Raise brightness, hold steady, zoom in on the code — or use Method 2 (manual entry) |
| "Unable to Add Cellular Plan" | No internet during download | Connect to Wi-Fi and try again; a stable connection is required to fetch the profile |
| Install stuck or failed | Temporary network hiccup | Restart your iPhone and repeat. Simbye QR codes can be scanned multiple times until they install successfully |
| eSIM installed but no signal | Line off, or Data Roaming off | Settings → Cellular → Simbye line: toggle the line On and Data Roaming On |
| No data even with roaming on | You're still at home | The eSIM connects at your destination — it won't pick up a local network until you arrive |
| Wrong line used for data | Default data line is your home SIM | Settings → Cellular → Mobile Data → select your Simbye eSIM |
Still stuck? Simbye's 24/7 support team responds in seconds via WhatsApp, Telegram, or Live Chat — real people who speak 12 languages, not chatbots. They'll walk you through it or reissue a fresh QR code if needed.

Frequently asked questions
How long does it take to install an eSIM on iPhone?
Under two minutes. Scanning the QR code and downloading the profile takes seconds; the longest part is labeling your lines and choosing a default, which adds maybe 30 seconds. If you use manual entry instead of scanning, add a few seconds to type in the SM-DP+ address and activation code.
How do I install an eSIM on iPhone without a QR code?
Use manual entry. Open Settings → Cellular → Add eSIM → Use QR Code → Enter Details Manually, then type the SM-DP+ address and activation code from your Simbye confirmation email. It installs exactly the same eSIM as scanning a QR code.
Can I install my Simbye eSIM before I travel?
Yes, and we recommend it. Install it at home while you're on Wi-Fi. Simbye eSIMs don't auto-activate, so your data validity only begins when you turn on the line and Data Roaming at your destination — installing early costs you nothing.
Why does my eSIM have no signal after installing?
Almost always one of two things: the line is switched off, or Data Roaming is off for that line. Go to Settings → Cellular → your Simbye line, toggle the line On, and turn Data Roaming On. And remember — the eSIM only connects to a local network once you've actually arrived at your destination.
Can I use my regular iPhone number and a Simbye eSIM at the same time?
Yes. Your iPhone supports Dual SIM, so you keep your home number active for calls and texts while the Simbye eSIM carries your data. Just set your default lines as described in the labeling step above.
Does a Simbye eSIM work with hotspot and tethering?
Yes — hotspot is included on every Simbye plan at no extra cost. Share your data with a laptop, tablet, or a travel companion's phone.
What if I run out of data?
Top up. Open your Simbye account or the app, select your eSIM, and add more data — there's no need to buy and install a new eSIM. Simbye was the first eSIM provider to offer easy top-ups.
The install failed — what now?
Check your internet connection and try again; if it's still stuck, restart your iPhone and repeat. Simbye QR codes can be scanned multiple times until they install successfully. If you're still having trouble, our 24/7 support team will help you over WhatsApp, Telegram, or live chat and reissue your QR code if needed.
