How to Activate Your eSIM on iPhone if You Bought It from an Android
To activate the eSIM on your iPhone, you need the QR code (or manual activation data) sent to you by your provider via email, even if you bought it from an Android phone. Go to Settings > Cellular > Add eSIM, scan the code with your camera, and follow the on-screen instructions. It takes a couple of minutes.
The point that confuses many people is this: it doesn't matter which phone you used to purchase the plan. An eSIM doesn't "live" on your Android or iPhone until the latter installs it; it resides in the confirmation email (or the provider's dashboard) in the form of a QR code and a set of manual activation data. If you bought it from your Android because that was the phone you had on hand, simply open that same email on your iPhone, or ask someone to forward it to you, and follow the normal installation process. There are no extra steps for having purchased "from the wrong operating system."
The only thing that matters is where you scan the code for the first time. If you already scanned it with your Android camera—even if it was accidental, just to see it better—it's likely that QR will be used up, and you'll need to proceed with the manual installation explained in section 5.
Can We Activate an eSIM from an Android to an iPhone?
Yes, but with an important clarification: the eSIM doesn't "transfer" from Android to iPhone like a photo via Bluetooth. What you do is open the same activation code on the iPhone that originally arrived in your email or was generated when you purchased the plan from the Android, and that code is what the iPhone uses to install its own profile.
An eSIM is not a file that can be sent from one phone to another: it's a profile that the provider activates against the IMEI of a specific device. What moves between phones is the activation code, never the eSIM itself.
This explains why, if you purchased the plan from an online store using your Android and then decide to install it on your iPhone, everything works without a problem: the activation code is not "tied" to the Android, it's tied to your purchase. You can open the confirmation email in any browser, on any phone, or even on a computer, as long as the iPhone where you're going to install the eSIM is the one that ultimately scans the code or receives the manual data.
To better understand exactly what is being installed, review our guide on what an eSIM is before proceeding with the steps.
Before Scanning the QR Code: 4 Things You Should Check
Before tapping Settings, check these things to avoid wasting time or accidentally using up the code:
- Stable Wi-Fi connection. The iPhone downloads the eSIM profile during installation; do it with Wi-Fi, not mobile data from another line, to avoid interruptions halfway through the process.
- The QR code has not yet been opened on another device. Open it directly on the iPhone (via email or browser), do not view it first on the Android with another camera.
- You have space for an additional line. Compatible iPhone models allow several eSIMs and one physical SIM at a time, but only one active line for data at any given moment if you are not using dual data.
- Sufficient battery. It's not a technically documented requirement by Apple, but if the iPhone runs out of battery halfway through the profile download, sometimes you have to restart the process from scratch.
Step-by-Step: Installing the eSIM on Your iPhone with a QR Code
This is the most common method and the one that resolves most cases:
- Open Settings on your iPhone.
- Go to Cellular (on some models, it appears as "Mobile Data").
- Tap Add eSIM or Set Up Cellular.
- Choose Use QR Code.
- Point your iPhone's camera at the QR code sent by your provider (on screen or printed).
- Tap Continue when the iPhone recognizes the code.
- Choose a name for the line (e.g., "Travel" or the destination name) to differentiate it from your usual line.
- Select which line you will use as default for calls and messages, and which for mobile data.
- Wait for the iPhone to finish activating the profile. This usually takes a few minutes.
If at any point the iPhone asks you to "confirm on your other device," it's only because it detected that you opened the email in more than one place; simply confirm on the iPhone and you're done.

Manual Installation: When the QR Has Already Been Used or You Can't Scan It
If the QR code has already been opened on your Android, on a computer, or in another app, the iPhone may reject it when scanning. For these cases, there is a second option: manual installation using SM-DP+ data and the activation code, which are usually provided in the same confirmation email, below or next to the QR code.
- Go to Settings > Cellular > Add eSIM.
- Choose Enter Details Manually instead of "Use QR Code".
- Enter the SM-DP+ server address and the activation code exactly as they appear in your email.
- Confirm and wait for the iPhone to download the profile.
A detail almost no one uses: there's no need to separate the server address and activation code into two different fields. If your provider gave you the full code in a single block (in the format that starts with "LPA:"), you can paste the entire thing into the first field of "Enter Details Manually" and the iPhone will automatically split it into server and code. This saves you from typing errors, which is the most frequent cause of manual installation failing the first time.
Why Can't I Activate My eSIM on My iPhone?
If you've reached this point looking for why the process isn't moving forward, this table covers the most common messages:
| What you see on screen | Probable cause | What to do |
|---|---|---|
| "Unable to scan QR code" | The code was already read on another device or browser | Ask your provider for the SM-DP+ data and use manual installation |
| "Could not activate cellular plan" | Temporary network failure between the iPhone and the provider's server | Wait a few minutes with stable Wi-Fi and try again |
| Camera does not recognize the QR code | You are viewing the QR on the same screen where you are trying to scan it, or there is a reflection | Open the email on another phone or computer and scan from there |
| The iPhone says it has reached the maximum number of lines | You have already installed other previous eSIMs that are still taking up space even if you don't use them | Delete an old eSIM profile in Settings > Cellular before adding a new one |
| It installs but there's no signal | You haven't selected that line for mobile data, or you are outside the coverage area | Check in Settings which line is active for data and confirm your location |
If the error persists after trying manual installation and restarting the iPhone, it's time to write directly to your provider's support instead of continuing to try on your own: they can see on the server side if the profile was generated correctly.

How to Check if Your iPhone is eSIM Compatible
Before struggling with the QR code, confirm that your model supports it. Generally, all iPhones from iPhone XS, XS Max, and XR onwards come with eSIM, with some regional variations:
| Model | eSIM Compatible? | Note |
|---|---|---|
| iPhone XS / XS Max / XR | Yes | First models with eSIM |
| iPhone 11, 12, 13 (all versions) | Yes | In addition to the physical SIM slot |
| iPhone 14 and later purchased in the US | Yes, eSIM only | No physical SIM slot |
| iPhone 14 and later purchased outside the US | Yes | Retain physical slot in addition to eSIM |
| iPhone SE (2nd generation and later) | Yes | Including the first 2020 version |
| iPhone 8, X and older | No | Do not have eSIM technology |
If your iPhone is second-hand or unlocked from a carrier, in some rare cases the original carrier blocked the eSIM function by software even on a compatible model. To check the complete list of phones—Android and iPhone—that accept eSIM, consult eSIM compatible phones.
You Switched from Android to iPhone: What Happens to Your Old eSIM
If the "from Android" in your search actually means you switched phones—you had an Android with an active eSIM and now you use an iPhone—there's something important to understand: the eSIM you had installed on the Android doesn't automatically move to the new iPhone. Being a profile linked to the hardware of your old Android, it remains "trapped" there even if you no longer use that phone.
What happens in that case depends on who issued the eSIM:
- If it's your main carrier's eSIM (the one you use all year), you need to ask the carrier for a new QR code for your iPhone. Most resolve this via chat or app in minutes.
- If it's a travel eSIM that you already used and expired, there's nothing to transfer: simply buy a new one for your next trip and activate it directly on your iPhone, without involving the Android at all.
- If it's a travel eSIM that you purchased but haven't activated yet, check if your provider allows you to resend the same code to another email or device. Many providers allow this because the QR and activation code reside in their system, not on your old phone.
To understand the difference between installing an eSIM for the first time and migrating it between phones, it helps to review how to install an eSIM.
If the Problem is with the Provider, Not the iPhone
So far, all of the above resolves most cases where the problem lies with the iPhone itself: an already used code, a skipped step, a model without eSIM. But if you've already tried manual installation, restarted the phone, and the profile still won't activate, the problem is probably on the provider's side: a poorly generated code, a downed server, or a plan that never processed correctly after purchase.
At that point, what helps most is not to keep trying the same thing, but to have someone to contact without being limited by office hours. At PuraSIM, 24/7 support in all languages via email and WhatsApp is designed precisely for this moment: when you've done everything correctly on your end and need someone on the other side to review the code from their system. Furthermore, activating a PuraSIM eSIM takes approximately 1 minute once the code is processed correctly, and you have 180 days from purchase to activate it, so there's no rush if you bought in advance and your trip is still some time away.

Frequently Asked Questions
Can I transfer my eSIM from Android to iPhone like a file?
No. An eSIM cannot be copied or sent between phones; what you use is the activation code (QR or manual data) that your provider generated, and that code is installed directly on the iPhone without actually passing "through" the Android.
Do I need Wi-Fi to activate the eSIM on iPhone?
It is highly recommended. The iPhone downloads the full profile during installation, and a stable Wi-Fi connection prevents the process from being cut off midway.
What happens if my iPhone says "Could not activate cellular plan"?
This is almost always a temporary communication problem between the iPhone and the provider's server. Wait a few minutes with stable Wi-Fi and try again; if the message repeats, contact your provider's support.
Can I have both my travel eSIM and my physical local SIM at the same time?
Yes, on iPhone models that retain a physical SIM slot, you can use both lines simultaneously: one for your usual number and another for travel data. On eSIM-only models (like the iPhone 14 and later sold in the US), you can have several eSIMs installed and choose which one to use for data.
How long does it take to activate the eSIM on iPhone?
Profile installation usually takes a couple of minutes. Data activation itself, once you arrive at your destination and the iPhone connects to the network, takes approximately 1 minute in the case of a PuraSIM eSIM.
Can I install the eSIM before traveling?
Yes, it is recommended to install it with Wi-Fi before your trip so you don't have to rely on an unfamiliar network upon arrival. Data plan activation, however, is usually best left until you are at your destination, unless your provider states otherwise.
What do I do if I lost the QR code or confirmation email?
Contact your provider via email or WhatsApp, stating your order number; they can resend the code or provide you with the manual installation data (SM-DP+ and activation code) without you having to repurchase.
Do unlocked iPhones (not tied to a carrier) work the same with eSIM?
Generally, yes, as long as the model is compatible. In isolated cases, an iPhone that was locked to a specific carrier may have the eSIM function restricted by software even after being unlocked; if this happens, confirm with the manufacturer or the original carrier.
In Summary
If you bought your eSIM from an Android but are going to use it on an iPhone, you don't need to do anything special: open the confirmation email directly on the iPhone, scan the QR code from Settings > Cellular > Add eSIM, and if the code has already been used, resort to manual installation using the SM-DP+ data. The confusion of "transferring" an eSIM between operating systems disappears as soon as you understand that the only thing that moves is the activation code, not the line itself.
And if after following all the steps the problem remains unresolved, it's probably no longer an issue with your iPhone but with the provider who issued the code. For your next trip, check out PuraSIM's international eSIM plans, with coverage in over 200 destinations and 24/7 support via email and WhatsApp for exactly these moments.
