Xiaomi APN Settings for TDC Denmark

Xiaomi APN Settings for TDC Denmark (2026 Guide)

This guide provides the correct APN (Access Point Name) settings for Xiaomi, Redmi, and POCO devices on TDC Denmark. If your mobile data is not working, this guide will help you configure your device correctly.

Quick Overview

  • Primary APN: internet
  • Username & Password: Leave both blank
  • Authentication Type: Leave unchanged/default unless TDC specifically instructs otherwise
  • APN Type: default,supl
  • APN Protocol: Leave the default value provided by your phone
  • MCC/MNC: 238 / 01 (leave the values provided by your phone)

If your data is already working, you typically do not need to change these settings.

Quick Navigation

Before You Change APN: Diagnose First

Before manually changing APN settings, check if APN is likely the issue:

  • If your data is already working: Do not change APN settings.
  • If the phone shows 4G/5G signal but no data: Check data balance, account status, and network provisioning first. If those are fine, the APN may be incorrect or missing.
  • If the APN is missing or incorrect: Manual configuration may be needed. APN settings are normally configured automatically by the SIM and carrier. Manual configuration may sometimes be necessary after a software update, SIM swap, or when using a device with a different regional configuration.
  • If 4G/5G icon shows but no internet: Check your APN settings, account status, data allowance, and network configuration.

Why APN Settings Matter

APN settings tell your phone how to connect to the carrier's mobile data service. If the APN is missing or incorrect, mobile data may fail even when the phone has a network signal. TDC usually sends these settings automatically, but manual configuration can be necessary after a software update, SIM swap, or if you are using a non-European ROM device. If your mobile data stopped working after a HyperOS update, resetting APN settings to default often resolves the issue.

Standard TDC Denmark APN Settings

The following settings are the standard APN configuration for TDC Denmark on Xiaomi devices, based on official TDC documentation.

Mobile Data APN Configuration

  • Name: TDC Internet (or any name you prefer)
  • APN: internet
  • Username: (leave blank)
  • Password: (leave blank)
  • MCC: Leave as automatically provided (238)
  • MNC: Leave as automatically provided (01)
  • Authentication Type: Leave unchanged/default unless TDC specifically instructs otherwise
  • APN Type: default,supl
  • APN Protocol: Leave the default value provided by your phone

Important Notes:

  • Not all fields need to be filled. Only enter the information required for your carrier.
  • If you have entered correct settings but the internet connection is still not working, restart your phone.

Step 1: Access APN Settings on Xiaomi

To configure APN settings on your Xiaomi, Redmi, or POCO device, follow these steps:

  • Open Settings on your phone.
  • Go to SIM cards & mobile networks.
  • Tap your TDC SIM card.
  • Select Access Point Names (APN).

Note: Menu names may vary slightly between HyperOS and MIUI versions.

Step 2: Configure or Reset APN

You have two options at this stage:

Option A: Reset to Default (Recommended First Step)

If you see a list of APNs, tap the menu icon (three dots) and select Reset to default. This restores the APN configuration provided by the device and carrier.

Option B: Manually Add or Edit APN (Only if Reset Fails)

If resetting does not work, you can manually add a new APN:

  1. Tap the + (Add) icon.
  2. Enter the settings from the table above. Only fill in the required fields; leave others unchanged.
  3. Tap Save and select the new APN.
  4. Restart your phone.

Important: Only change the APN if resetting to default doesn't work. Leave other fields (MCC, MNC, APN protocol) as provided by your device. If the APN is already set correctly, do not change it. If you created several APNs while troubleshooting, remove the unnecessary custom entries.

MMS Settings (Optional)

If you are having issues sending or receiving picture messages, you may need to configure the MMS settings separately. Most modern devices handle this automatically.

MMS Configuration

  • Name: TDC MMS
  • APN: mms
  • MMSC: http://mmsc.tdc.dk:8002
  • MMS Proxy: inetproxy.tdc.dk
  • MMS Port: 8080
  • Authentication Type: Leave default
  • APN Type: mms
  • APN Protocol: Leave default

Troubleshooting & Additional Notes

After HyperOS Updates

After a major system update, check whether the TDC APN profile is still present before manually creating a new one. If the APN was changed or removed, resetting the APN to the carrier defaults can restore the automatic configuration.

5G and APN

The APN used for mobile data does not normally change simply because the phone connects to 5G. If 4G works but 5G does not, check your subscription, 5G coverage, device compatibility, and preferred network mode before changing the APN.
