How it works

  1. Choose your plan and choose eSIM. All four plans are available as eSIM.

  2. After your order you get your QR code and PIN by email. You’ll also find the code in the UNDO app and in My UNDO.

  3. Scan the code. Your phone installs the eSIM in about a minute, with no card to insert.

Note: you can only install the QR code once. So don’t delete the eSIM from your phone. An eSIM costs nothing extra at UNDO.

How quickly are you connected?

  • Installing: about a minute after you have the QR code.

  • New number: active within the hour, often sooner.

  • Keeping your number: usually within 24 hours, exceptionally up to 5 working days. That depends on your current operator, who has to release your number.

Your old SIM card keeps working until the transfer is complete. You get a text as soon as your number is active at UNDO.

Does your phone support eSIM?

When you order, you enter the make and model of your smartphone. We check straight away whether it supports eSIM. If not, you choose a physical SIM card. So you can’t order the wrong one.

Want to check yourself? In your phone’s settings, go to “Mobile data” or “SIM card manager”. If you see an option for eSIM or “add plan”, it works. Smartwatches aren’t supported for now.

Keeping your number

Keeping your current number is free. You enter your current operator’s details, and we handle the switch. We also cancel your old subscription for you.

Two numbers on one phone

Many eSIM phones support dual SIM: your current SIM card and an eSIM side by side. Handy for keeping work and personal separate, without a second phone. Do check that your phone can keep both lines active at the same time.

For a second number, Zero Waste is often enough: 4 GB of data, 400 minutes and 400 texts for €4 a month. What you don’t use carries over to the next month. Also read which plan suits low data use.

The plans

All four plans are available as eSIM, can be cancelled any month and run on Orange’s 5G network. With every plan you support certified climate projects with CO₂ credits.

  • Zero Waste: 4 GB of data, 400 minutes and 400 texts for €4 a month

  • Rise: 8 GB of data, 800 minutes and 800 texts for €8 a month

  • Boost: 30 GB of data, unlimited calls and 100 texts for €18 a month

  • Wild: 40 GB of data, unlimited calls and texts for €24 a month

What you don’t use carries over to the next month.
