In short: To activate an eSIM on your iPhone 15 without a QR code, go to Settings > Cellular > Add eSIM, choose "Enter Details Manually," and type the SM-DP+ server and activation code that PuraSim sends you via email. Within 5-15 minutes, you'll have internet access, no roaming, and no need to scan anything.
Buying a travel eSIM is the easy part. The real question comes right after: how do I get it onto my phone if I don't have a printer handy or another screen to scan the QR code? If you have an iPhone 15, the good news is that Apple has been preparing for this moment for years, and manual activation is just as valid as QR code activation. In this guide, we'll explain, step-by-step and without technical jargon, how to activate an eSIM on an iPhone 15 without a QR code, when each method is best, and what to do if something gets stuck.
Why activating an eSIM without a QR code makes perfect sense
A QR code is convenient when you open it on a computer and scan it with your phone. But in the real world, many times the QR code arrives on the same iPhone where you want to install the eSIM. And that's where the classic problem arises: you can't point the phone's camera at an image that's on the screen of that same phone.
That's where manual activation comes in. Instead of scanning, you enter two pieces of text data (the SM-DP+ server and the activation code), and the iPhone downloads the exact same profile. It's the ideal method if you're traveling light, if you don't have a second screen, if the QR code is blurry, or if you simply prefer typing to pointing a camera. The result is identical: your data line is ready to work as soon as you arrive at your destination.
Is the iPhone 15 compatible with eSIM?
All iPhone 15 family models are fully compatible with eSIM. The technology is integrated as standard into the hardware, so you don't need any additional physical card or chip to insert. You just need to download the digital profile and activate it.
An important nuance depending on where you bought the phone: in the United States, the iPhone 15 is exclusively eSIM and does not have a tray for a physical SIM. In the rest of the world, including Spain, models retain the physical SIM slot and also support eSIM, allowing you to combine your usual line with the travel eSIM.
| Model | eSIM Compatible | Dual Active eSIM | Physical SIM Slot (outside US) |
|---|---|---|---|
| iPhone 15 | Yes | Yes | Yes |
| iPhone 15 Plus | Yes | Yes | Yes |
| iPhone 15 Pro | Yes | Yes | Yes |
| iPhone 15 Pro Max | Yes | Yes | Yes |

Before you start: what you need to have on hand
Activation is quick, but it's less likely to get stuck if you prepare three things beforehand. First, a stable WiFi connection: the eSIM profile is downloaded via the internet, and it's best to do it before leaving home. Second, an unlocked iPhone 15 (carrier-free); if you bought it with a contract, check that it's already unlocked. Third, the PuraSim confirmation email, where you'll find both the QR code and the manual activation data.
A tip that almost no one gives: install the eSIM a few days before your trip, not at the airport counter. Installing the profile doesn't consume data or "start" the plan; for most travel eSIMs, the day counter begins when the line first connects to a network at the destination, not when you download it. This way, you arrive with everything ready and just need to activate data upon landing.
How to activate an eSIM on iPhone 15 without a QR code (step-by-step)
This is the star method of this guide. You need two pieces of information that appear in your PuraSim account and in the confirmation email: the SM-DP+ server (a web-like address) and the activation code. With these, follow these steps:
- Open Settings on your iPhone 15.
- Go to Cellular (in some versions it appears as "Mobile").
- Tap Add eSIM or Add Data Plan.
- If it offers to transfer from another iPhone, tap Use QR Code below, then Enter Details Manually.
- Enter the SM-DP+ server and the activation code exactly as they appear in your PuraSim email (respect capitalization, hyphens, and periods).
- Confirm and wait for the profile to download, which usually takes between 5 and 15 minutes.
- When finished, label the line (e.g., "Travel" or "PuraSim") to distinguish it from your main line.
- Choose which line will use data and which will remain for calls and SMS. You can change this whenever you want.
And that's it. The eSIM is installed. Remember that data will only start flowing when you activate data roaming for that line at your destination, a step we'll look at below.
How to activate an eSIM on iPhone 15 with a QR code
If you have a second screen (a computer, a tablet, or a companion's phone) where you can open the QR code, this method is even faster because you don't have to type anything.
- Open the PuraSim email on that second screen and have the QR code visible.
- On the iPhone 15, go to Settings > Cellular > Add eSIM.
- Select Use QR Code.
- Point the camera at the QR code until it recognizes it.
- Confirm the installation and wait 5 to 15 minutes.
- Activate the new line from Settings > Cellular.

With or without QR: which method is right for you?
Neither is "better" in the abstract; it depends on your situation. This table will help you decide in ten seconds.
| Situation | Recommended Method | Why |
|---|---|---|
| QR code arrives on the same iPhone | Without QR (manual) | You can't scan a screen with its own camera |
| You have a computer or second screen | With QR | It's instant and no typing is needed |
| QR code is blurry or won't scan | Without QR (manual) | Text code avoids camera problems |
| You're without a printer or paper | Without QR (manual) | You only need to copy two pieces of data from the email |
| Switching from one iPhone to another with iOS 16+ | Wireless transfer | Moves the line without reactivating it |
Activate data upon landing (the step many forget)
Installing the eSIM is not the same as turning on data. When you arrive at your destination, do this to truly connect:
- Go to Settings > Cellular.
- Under Default Data Plan, select the PuraSim line.
- Go into that line and activate Data Roaming. Don't worry: with a travel eSIM, this is normal and doesn't incur extra charges from your carrier, because you're not using your Spanish line.
- Deactivate data for your usual line to avoid accidentally using it.
That roaming switch is the source of most "it's not working" issues. If the concept confuses you, we clarify it without jargon in what data roaming is. And if you come from the world of traditional roaming and want to see the fundamental difference, compare both approaches in eSIM vs roaming.
Transferring eSIM between iPhones
As of iOS 16, Apple allows you to wirelessly move an eSIM from one iPhone to another without going through the carrier. This is very useful if you're getting a new iPhone 15 and want to keep an active line.
- Place both iPhones close together, with Bluetooth turned on.
- On the iPhone 15, go to Settings > Cellular > Add eSIM.
- Choose Transfer from nearby iPhone and follow the instructions on both devices.
- Confirm the transfer on the old phone.
Be careful with one detail: wireless transfer is primarily designed for your carrier's eSIM. For a PuraSim travel eSIM, the usual and safest method is to reinstall it on the new phone using the activation code. If you're going to switch devices, we guide you on how to transfer an eSIM to a new iPhone.
What almost no one tells you about eSIM on iPhone 15
Beyond the step-by-step instructions, there are several details that make the difference between a connected trip and an afternoon struggling with Settings. These are the ones that save the most headaches.
The day counter does not start upon installation
For most travel eSIMs, installing the profile doesn't start the plan. The validity period usually begins when the line first connects to a network at the destination. That's why you can (and should) install it calmly from home with WiFi.
Data roaming is NOT your expensive roaming
Many people see the word "roaming" and panic about bills. With a travel eSIM, that switch only indicates that the eSIM connects to local networks in the country; it does not affect your Spanish plan. Without that switch activated, the eSIM won't provide data. Activate it without fear.
Save the activation email, not just the QR code
The QR code can often only be reinstalled once. If you need to reinstall the eSIM (new phone, accidentally deleted), having the SM-DP+ server and activation code handy will save you. Archive that email in a "Travel" folder.
Label your lines well
When you have your usual line and your travel line coexisting, it's easy to send WhatsApps with one and data with another without realizing it. Give them clear names ("Spain" and "Travel") and decide which line uses data. This way you avoid accidentally spending your national plan.
Deactivate data on your main line abroad
The most expensive mistake is not from the travel eSIM, but from your home line being left with data on. Before taking off, go into your usual line and deactivate its mobile data. The travel eSIM will take care of everything.
Optimize consumption from day one
If you buy a tight plan, a few adjustments (deactivating background app refresh, lowering video quality, avoiding automatic backups on data) can stretch your gigabytes a lot. You have a complete list in how to save data with your travel eSIM.
Solutions to common problems on iPhone 15
QR code won't scan
Clean your camera lens, find good lighting, and adjust the distance to the code. If it still doesn't read, don't insist: switch to manual activation with the SM-DP+ server and activation code. This usually solves the problem instantly.
The option to add eSIM does not appear in Settings
Check that your iPhone 15 is updated to the latest iOS version and that it is carrier unlocked. If you bought the phone with a contract, it might still be locked; ask your carrier if the device is already unlocked.
eSIM installs but doesn't activate
Restart your iPhone 15 and go back to Settings > Cellular to activate the line. Verify that data roaming is enabled on the PuraSim line. If the problem persists, you have a step-by-step diagnosis in why an eSIM doesn't activate and how to fix it.
I have signal but no internet browsing
Make sure the PuraSim line is set as the Default Data Plan and that data roaming is active on that line. A quick restart after landing helps the iPhone connect to the correct local network.
Choose your eSIM according to your destination
Once you master activation, the only thing that changes from one trip to another is which plan you install. PuraSim has coverage for most destinations, so you just need to choose the one that matches your route. If you're traveling across the continent, the eSIM for Europe covers dozens of countries with a single profile. To cross the pond, the eSIM for the United States keeps you connected right from the airport. And if you're from abroad and coming to the peninsula, the eSIM for Spain is ready to install before you land.
Frequently Asked Questions
Can I truly activate an eSIM on iPhone 15 without a QR code?
Yes. The iPhone 15 allows you to manually enter the SM-DP+ server and activation code from Settings > Cellular > Add eSIM > Enter Details Manually. It downloads the same profile as the QR code, with no need to scan or print anything.
Where do I find the SM-DP+ and activation codes?
Both pieces of information appear in your PuraSim confirmation email and in your account, directly below or next to the QR code. Copy them exactly as they appear, respecting capitalization, periods, and hyphens, for the iPhone to recognize the profile.
Does the iPhone 15 have an integrated eSIM?
Yes, all models (iPhone 15, 15 Plus, 15 Pro, and 15 Pro Max) include eSIM as standard. You don't need any accessories or a physical card to use a travel eSIM.
How long does it take to activate the PuraSim eSIM?
The profile download and installation usually take between 5 and 15 minutes from when you start the process. Data begins to work when you activate data roaming for that line at your destination.
Do I need WiFi to activate the eSIM?
WiFi (or an already working data connection) is recommended for the initial profile download. Once installed and activated, the eSIM works on its own with the country's network, without relying on WiFi.
Do I need to unlock my iPhone 15 to use a travel eSIM?
Yes, the iPhone must be carrier-unlocked to install an eSIM from another provider like PuraSim. If you bought it with a contract, confirm with your carrier that the device is already unlocked.
Can I have my Spanish line and the travel eSIM at the same time?
Yes. The iPhone 15 supports dual SIM, so you can keep your usual number for calls and SMS while using the PuraSim eSIM for data. Just remember to choose the travel line as your default data plan and deactivate data for your main line to avoid using it.
