Xiaomi eSIM Not Activating on TDC Denmark

Xiaomi eSIM Not Activating on TDC Denmark: 2026 Troubleshooting Guide

📌 Quick Answer – If Your Xiaomi eSIM Won't Activate on TDC:

  • ✓ Check device compatibility – eSIM support varies by Xiaomi model and region. Check by dialing *#06# for an EID or looking in Settings for eSIM options.
  • ✓ Check your plan – TDC supports eSIM for mobile subscriptions. Contact TDC if you are unsure about your specific plan.
  • ✓ Follow TDC's activation instructions – If TDC specifically tells you to remove the physical SIM during eSIM activation, follow that instruction.
  • ✓ Make sure Wi-Fi is on – A stable internet connection is required to download the eSIM profile.
  • ✓ Try manual activation – If QR scanning fails, use the SM-DP+ address and activation code provided by TDC.

If eSIM still doesn't work, follow the step-by-step guide below.

If your Xiaomi, Redmi, or POCO phone fails to activate the eSIM, shows an "invalid activation code" error, or the eSIM option is missing on TDC Denmark, this guide covers the most common causes and troubleshooting steps.

Before You Start – Quick Checks

  • Check device compatibility – Not all Xiaomi models support eSIM. Use the steps below to verify your specific model.
  • Check for EID – Dial *#06# on your phone. If an EID number appears, your device has eSIM hardware capability.
  • Connect to Wi-Fi – A stable Wi-Fi or internet connection is recommended while downloading and installing the eSIM profile.
  • Check your TDC subscription – TDC provides eSIM activation through Selvbetjening (self-service) for business and personal subscriptions.

If these quick checks don't work, continue with the step-by-step guide below.

Quick Navigation

Diagnose the Issue First

Before making changes, determine the pattern of your eSIM activation issue:

  • Is the eSIM option missing entirely? – If not, your Xiaomi model may not support eSIM, or the feature is hidden.
  • Does your device show an EID? – Dial *#06#. An EID indicates that the phone has an eSIM/eUICC identifier, but availability can still depend on the exact model, regional variant, software configuration, and carrier support.
  • Do you have a QR code or activation details? – TDC provides eSIM through Selvbetjening or via email.
  • Does the activation code show as "invalid"? – This can happen if the code has expired, is not correctly associated with your account, or if the activation details are incorrect.
  • Did the profile install but you have no network? – This indicates a provisioning or network registration issue, not a problem with the installation itself.

Why This Happens

  • Device incompatibility – Not all Xiaomi models support eSIM. Even models that support eSIM may have regional variations where the feature is not available or fully supported.
  • Activation method mismatch – TDC supports eSIM activation through QR code or manual entry. TDC notes that on some devices (like iPhone), QR scanning through settings may not work, and the camera app should be used first.
  • Software or carrier-configuration issues – An outdated system or a device/carrier configuration problem can interfere with eSIM activation.

Quick Diagnostic Table

  • No EID / no eSIM controls → Device capability/variant – verify exact model and region
  • EID exists, but no eSIM menu → Software, region, or model issue – check Xiaomi support
  • TDC won't issue eSIM → Account or subscription issue – contact TDC
  • QR code is rejected → Activation or profile issue – get fresh activation from TDC
  • Profile installs but no network service → Provisioning or network registration issue – contact TDC

Step 1: Verify eSIM Support on Your Xiaomi

Why this matters: Before troubleshooting, confirm that your device actually supports eSIM. Xiaomi recommends checking for an EID number using the code *#06# or checking the device settings.

Method 1 – Check EID:

  1. Open the Phone app
  2. Dial *#06#
  3. Look for an EID number (eSIM ID). An EID indicates that the phone has an eSIM/eUICC identifier, but eSIM availability can still depend on the exact model, regional variant, software configuration, and carrier support.

Method 2 – Check Settings:

  • Go to Settings → SIM cards & mobile networks
  • Look for eSIM management or eSIM options
  • If you see options to add or manage an eSIM, the device supports it.

Important note: If no EID appears and there is no eSIM option, the device may not support eSIM, or eSIM functionality may be unavailable on that regional variant or software configuration. eSIM availability varies by exact Xiaomi model and regional variant. Do not assume that every version of a model sold globally supports eSIM.

If an EID appears and the eSIM menu is available, continue with Step 2.

If no EID appears and no eSIM menu exists, your device may not support eSIM. Check the exact model and regional specifications before concluding that eSIM is unavailable.

Step 2: Get Your eSIM from TDC

Why this matters: TDC provides eSIM activation through its self-service channels. The exact process can differ between personal and business subscriptions.

For personal customers:

  • Log in to TDC's Selvbetjening (self-service) portal
  • Navigate to your subscription details
  • Look for an option to order or activate an eSIM
  • Follow the instructions to generate or receive your eSIM QR code

For business customers:

  • IT administrators can find eSIM information in Selvbetjening Erhverv (business self-service) under the subscription's SIM section.
  • They can either view the SM-DP+ address and activation code for manual activation, or send the QR code to the employee's email.

If you cannot find the QR code in Selvbetjening or the app, contact TDC directly.

Step 3: Activate via QR Code

Why this matters: TDC provides a QR code for eSIM activation. On Xiaomi devices, the exact activation flow can vary by model and software version, so use the eSIM option shown in your phone's settings.

Try the QR code using the method shown by your device:

  1. Use the built-in method: Navigate to Settings → SIM cards & mobile networks → Select eSIM management or eSIM → Select Add eSIM → Select Scan QR code.
  2. Scan the QR code provided by TDC (from Selvbetjening or email).
  3. Follow on-screen prompts to download and install the eSIM profile.

If the QR code is displayed on the same Xiaomi you're configuring:

  • Open it on another screen such as a computer or second phone, then scan it with the Xiaomi.
  • Alternatively, use the manual activation option if TDC provides the SM-DP+ address and activation code.

If QR code activation fails, move to Step 4.

Step 4: Activate via Manual Code (SM-DP+ and Activation Code)

Why this matters: Some devices may require manual entry of activation details if the QR code cannot be scanned. TDC provides manual activation details through Selvbetjening.

  1. Navigate to Settings → SIM cards & mobile networks
  2. Select eSIM management or eSIM
  3. Select Add eSIM
  4. Select Enter activation code manually (on some devices, this may appear after selecting "Scan QR code" and then choosing "Enter details manually")
  5. Enter the SM-DP+ Address and Activation Code provided by TDC (from Selvbetjening or email)
  6. Follow on-screen prompts

Important: Do not guess or modify the SM-DP+ address or activation code. Use only the activation details supplied by TDC.

If the eSIM profile installs successfully but you have no service, continue to Step 5. If the activation code itself is rejected, contact TDC for a new or verified activation profile instead of proceeding with network troubleshooting.

If manual activation fails, move to Step 5.

Step 5: eSIM Installed but No Service

Why this matters: If the eSIM profile installs successfully but you have no network service, the problem is more likely to involve network registration, carrier provisioning, coverage, or device configuration than the eSIM download itself.

  • Make sure the eSIM is enabled – Go to Settings → SIM cards & mobile networks and ensure the eSIM is active and selected for data/calls.
  • Toggle Airplane Mode – Turn on for 30 seconds, then off to refresh network registration.
  • Restart your phone – A restart can help the device register on the network.
  • Check network mode – Ensure the preferred network type includes 4G/5G.
  • Contact TDC – If the eSIM shows "No Service" or the carrier name is not displayed, TDC may need to complete provisioning on their side.

Do not repeatedly delete the eSIM. If the profile has already been installed, deleting it can create another activation problem without fixing a carrier-side provisioning issue.

If the issue persists, move to Step 6.

Step 6: Check for System Updates

Why this matters: Software updates often include modem and carrier configuration improvements that can enable or fix eSIM functionality.

  1. Settings → About phone → Check for updates
  2. Install any available updates
  3. Restart your phone and try the eSIM activation again

If you're already on the latest version and eSIM still doesn't work, move to Step 7.

Step 7: Reset Network Settings

Why this matters: This can help if the eSIM is installed but the phone cannot register correctly on the mobile network. It is less likely to fix a QR-code or eSIM-download error.

Do not use a network reset as the first response to an invalid QR code or activation code. Those errors are more likely to involve the activation profile or carrier provisioning.

  1. Settings → Connection & sharing (HyperOS) or Settings → Additional settings → Backup & reset (MIUI)
  2. Select Reset Wi-Fi, mobile & Bluetooth or Reset network settings
  3. Confirm the reset
  4. Restart your phone
  5. Try the eSIM activation again

If eSIM still doesn't work, contact TDC or Xiaomi support.

Decision Box – What to Do Next?

Still not working? Let's narrow it down:

  • ✓ No EID / no eSIM controls? → Your device may not support eSIM. Verify the exact model and regional variant.
  • ✓ EID exists, but no eSIM menu? → This could be a software, region, or model issue. Check Xiaomi support.
  • ✓ TDC won't issue eSIM? → The issue may be with your account or subscription. Contact TDC.
  • ✓ QR code is rejected? → This is likely an activation or profile issue. Get a fresh activation from TDC.
  • ✓ Profile installs but no network service? → This is likely a provisioning or network registration issue. Contact TDC. Do not repeatedly delete and reinstall the eSIM.
  • ✓ eSIM works on another device but not yours? → The issue is Xiaomi-specific. Check model, ROM, and software.

Contact Carrier (When Required)

Contact TDC Denmark if:

  • You've tried all steps above and eSIM still doesn't work
  • You need a new activation code or QR code
  • You need to check that your account is properly provisioned for eSIM
  • The eSIM installs but shows "No Service" – TDC may need to complete provisioning on their side

TDC Support (Denmark)

  • TDC Help Centre: tdc.dk/kundeservice
  • TDC Business Support: tdc.dk/erhverv
  • TDC App: Mit TDC (available on Google Play Store)
  • Check TDC's official contact page for the latest support number and hours.

Contact Xiaomi Support if:

  • You've tried all steps above and eSIM still doesn't work
  • Your device is on the compatible list but eSIM still fails
  • You suspect a software or hardware issue with your device

Xiaomi Support

Final Verdict

If your Xiaomi eSIM won't activate on TDC Denmark, follow this diagnostic flow:

  1. Confirm your device has eSIM capability – Dial *#06# and look for an EID. If no EID appears, the device may not support eSIM on that variant.
  2. Get your eSIM from TDC – Use Selvbetjening to obtain the QR code or activation details.
  3. Scan the QR code – Use the built-in eSIM activation method in Settings. If the QR code is on the same phone, use another screen or try manual activation.
  4. Try manual activation – If the QR code doesn't work, use the SM-DP+ address and activation code from TDC.
  5. Check provisioning – If the eSIM installs but shows "No Service", contact TDC. This is likely a provisioning issue, not a device problem. Do not repeatedly delete and reinstall the eSIM.
  6. Check for system updates – May contain modem or carrier fixes.
  7. Reset network settings – As a last-resort device configuration step.

Contact TDC to verify your account provisioning if none of these steps resolve the problem.
