eSIM – help & setting up

Learn what an eSIM is, how to get hold of one and how to activate it on your device. You will also find answers to frequently asked questions and helpful downloads.

Quick start: activate an eSIM on iOS and Android in just a few steps.

What is an eSIM?

An eSIM (embedded SIM) is a digitally programmable SIM chip that is permanently installed in a device. Unlike with a physical SIM card, there is no need to insert a card – tariffs are installed by profile via a QR code, an activation app or the device menu. This is practical, plastic-free and enables multiple profiles on one device (e.g. business and private).

  • Active immediately – no waiting on the post
  • Manage multiple profiles on one device
  • Less plastic, robust and future-proof
  • eSIM-enabled device (smartphone, tablet, watch)
  • Supported mobile phone tariff
  • Stable data connection for activation

Getting an eSIM

As a provider, we offer a self service portal, where the person responsible for mobile communications can purchase eSIMs for all subscriptions in one place.

A QR code for the eSIM can be created in the portal and sent directly to the end users. They then scan the code and activate the eSIM on their device.

Alternatively, the eSIM can be linked to a specific EID (eSIM ID). The end user can then download the eSIM directly via the device menu – without any need for a QR code.

If an end user changes their device, manufacturers such as Apple, Samsung and Google offer convenient transfer tools (e.g. Quick Transfer) which will transfer an eSIM profile quickly and securely to the new device.

Setting up an eSIM

iPhone (iOS)

  1. Open Settings → Mobile Network → Add eSIM.
  2. Tap on Use QR Code and scan the eSIM QR code from your provider.
  3. Follow the instructions, enter a tariff name (e.g. “Private”) and confirm.
  4. Under Mobile Data, select the standard tariff and activate data roaming if applicable.

Note: iOS also supports eSIM Quick Transfer between iPhones.

Android (e.g. Samsung/Google)

  1. Open Settings → Connections → SIM Manager (names may vary depending on the manufacturer).
  2. Select Add eSIM and scan the QR code or enter the SM‑DP+ address and activation ID.
  3. Follow the on-screen instructions and activate the new mobile plan.
  4. Specify the default SIM for data/calls and check the roaming settings.

Tip: some devices allow eSIM transfer by manufacturer account (e.g. Samsung account).

Wearables (e.g. smartwatch)

Activation is usually via the smartphone app for the watch (e.g. “Watch” app). Navigate to Set Up Mobile in the menu and log in with your provider to download the Companion profile.

FAQs

Can I use multiple eSIM profiles on one device?

Yes, lots of smartphones support multiple profiles. Generally speaking, one or two profiles can be active at the same time – depending on the model.

Do I need special settings for roaming?

Activate data roaming in the relevant eSIM profile. Check tariffs and country coverage with your provider before you travel.

What if the QR code doesn’t work?

Check your Internet connection and camera focus. Alternatively, enter the SM‑DP+ address and activation ID manually or request a new code.

Can I switch from a physical SIM to an eSIM?

Yes. Your provider will issue an eSIM profile to allow this. Following successful activation, you can remove the physical SIM.
