How to Generate a QR Code from Activation Code for Free?

Paste the entire activation string in the format LPA:1$smdp.io$abcdef1234567890$ICCID into the generator and you'll get a QR code ready to scan.

Activation code → QR

Make your eSIM scannable

Paste the activation code from your provider. It stays in this browser and is never uploaded.

Ready to scan

Scan this with the phone you want the eSIM on. Use a second screen, because a phone cannot scan its own display.

    Make sure you've copied the entire code exactly as provided by your eSIM provider. If your code looks different, for example if the SMDP address is listed separately, see the analysis of the activation code. Once your QR code is ready, continue to the guide on activating your eSIM.

    Tip for successful activation: You can save the generated QR code as an image or print it out. If you're traveling, we recommend having a backup of the QR code in case you need to reactivate your eSIM.

    Analysis of eSIM Activation Code

    When you purchase an eSIM from any provider, you typically receive a special activation code in this format:
    LPA:1$smdp.io$abcdef1234567890$ICCID

    This eSIM activation code consists of several key components that are essential for successful activation:

    • LPA:1 – Indicates that this is an eSIM profile (Local Profile Assistant), which is the standard for activation.
    • SM-DP+ address (e.g., smdp.io) – The server address from which your phone securely downloads the eSIM profile.
    • Activation code (e.g., abcdef1234567890) – A unique code that your phone uses when downloading and verifying the eSIM.
    • ICCID – The SIM card identification number (often visible as the last item), which uniquely identifies your virtual SIM card.

    Important note: Different eSIM providers may format the activation code slightly differently. Some, for example, list the SMDP address separately. For successful QR code creation, all parameters need to be arranged in the format shown above.

    Why Do You Need a QR Code for eSIM Activation?

    Modern phones with eSIM support allow you to add virtual SIM cards most conveniently by scanning a QR code. This activation method offers several key advantages over manual entry:

    • Activation speed – Just scan and within seconds, your eSIM is ready to use.
    • Error elimination – Avoid typos when manually typing a long activation code.
    • Universality – Works the same on all devices supporting eSIM, regardless of manufacturer.
    • Convenience – You can save the QR code for possible later eSIM reactivation.

    The QR code can be displayed on any device screen or printed on paper, and your phone's camera will read everything automatically. This activation method is used by all leading providers of travel eSIMs and local carriers.

    Where Did the QR Code Come From?

    The little black-and-white square you just used to build your eSIM QR code has a much longer history than most people realize. The QR code was invented in 1994 by engineer Masahiro Hara and his team at Denso Wave, a Japanese company under the Toyota Group. Their goal had nothing to do with smartphones or eSIMs, it was tracking car parts on the assembly line faster than the barcodes of the time allowed.

    Traditional barcodes could hold only about 20 characters and had to be scanned from a fixed direction, which slowed workers down considerably. Hara's team designed a two-dimensional code that could store thousands of characters, be read from any angle thanks to its three distinctive corner squares, and still work even if part of it was scratched or dirty. The name itself stands for Quick Response, a nod to the speed that was the whole point of the invention.

    One decision turned out to matter just as much as the design: Denso Wave chose not to enforce royalties on the format, letting anyone use it freely. That openness is a big reason the QR code eventually spread far beyond factories, into everything from marketing posters to restaurant menus to, of course, eSIM activation.

    Today, QR codes are a genuinely everyday tool, used for payments, boarding passes, product packaging, and increasingly official documents and invoices. In Switzerland, for example, Tariff 595, the billing standard covering health-promotion and prevention services such as fitness subscriptions and wellness courses, now has every printed invoice carry an automatically generated QR code as a safeguard once the document is issued. You can read more about how the standard works at standard595.ch. It's a small example of how far a format invented for tracking auto parts has traveled, all the way into everyday paperwork.

    Frequently Asked Questions about Converting eSIM Activation Code to QR Code

    Frequently Asked Questions

    What should I do if the QR code doesn't work when activating eSIM?
    If you're having trouble activating your eSIM with the QR code, check that you've correctly copied the entire activation code including all parts described in this article, such as the LPA prefix. You can also scan your created QR code with a QR reader to verify it contains all the components shown in our example. If the code looks like our example but the eSIM still won't load, please contact your provider for assistance.
    Can I use one QR code to activate an eSIM on multiple devices?
    No, each eSIM QR code is typically one-time use only and cannot be used on another device after activation. If you need eSIM on multiple devices, you'll need a separate eSIM plan for each of them.
    Is activating an eSIM using a QR code secure?
    Yes, activating an eSIM via QR code is a secure method supported by all device manufacturers and virtual SIM card providers. The code contains encrypted information, and the connection with the provider occurs over a secure connection. However, it's still important to obtain activation codes only from trusted sources.
    How long does an eSIM QR code remain valid?
    The validity of an eSIM activation QR code varies by provider. Typically, it's valid from 15 days to several months after purchase. You should receive exact information about validity from your eSIM provider. After the QR code expires, you won't be able to activate the eSIM and will need to contact the provider for a new code.
    What if I don't have a second screen to display the QR code for scanning?
    You can also load an eSIM QR code from an image file, which means you can simply take a screenshot of the QR code returned by the generator on this page and then select the image instead of using the camera during eSIM installation.
    Can I convert an eSIM activation code to a QR code offline, without an internet connection?
    Most QR generators, including the one on this page, work online, but there are also offline applications for generating QR codes that you can use without an internet connection. Just install such an app in advance and then enter the activation code in the correct format. Keep in mind that you will need an internet connection for the actual eSIM activation.
    How do I know if I've correctly formatted the activation code for conversion to a QR code?
    A properly formatted eSIM activation code typically has the format 'LPA:1$server_address$activation_code$ICCID'. If you're unsure, compare your code with the example in our guide. If in doubt, contact your eSIM provider, who should provide precise instructions for formatting the code or give you a ready-made QR code.

    Why can you trust Vefru?

    Founders František and Jan experienced problems with mobile data every time they traveled outside the EU. As technology enthusiasts, the idea of traveling abroad without a data connection or risking truly insane roaming fees was unacceptable to them. Regardless of how adventurous the story of walking across Toronto on a winter night without an online map might be, it's not something they would want to repeat.

    After the emergence of eSIM and later eSIM travel data package providers, they learned a lot about the technology and industry and decided to share their findings and the comparison tool they created for themselves with others. It now contains more than 20,000 updated eSIM mobile data packages from the most popular providers for more than 170 countries around the world.

    Every time you read a guide on Vefru, it is created in the same way the author would research the topic themselves. From contacting locals about the best network operators, to recommending the most advantageous plans for what you really need, to technical guides on how to create a QR code for eSIM or how to troubleshoot eSIM issues. Most articles are created based on topics that the authors themselves have dealt with and for which they found the best solutions.
