- Use a different APN (see next section for alternatives).
- Try resetting your network settings in the phone’s settings menu.
MMS Not Sending or Receiving

Contacting TDC Support for APN Issues

| Support Channel | Contact |
| Phone | +45 70 70 90 90 |
| Website | www.tdc.dk |

When reaching out, mention:

What is an APN and Why Does it Matter?
Understanding APN in Simple Terms
The Access Point Name (APN) is like a bridge between your phone and TDC’s network. If the APN is wrong, your mobile data won’t work properly.
Why Correct APN Settings Matter
- No mobile data? Your APN could be misconfigured.
- Slow speeds? The wrong APN might be restricting bandwidth.
- Can’t send MMS? Your APN might not be set up for multimedia messaging.
Common APN-Related Problems
- No 4G/LTE signal despite full bars.
- Internet works, but MMS won’t send.
- Connection keeps dropping or is unstable.
My Go-To TDC APN Settings for International Roaming
From my experience, these are the default APN settings that work in most countries:
- APN: internet
- Username: (leave blank)
- Password: (leave blank)
These settings typically work fine, but I always keep in mind that some countries might require slight adjustments.
How I Ensure a Smooth TDC Roaming Experience
While the general APN settings usually get the job done, I’ve realized that knowing which local networks TDC partners with can be a lifesaver when troubleshooting connectivity issues. Here’s the list of network operators I connect to while roaming in different countries:
TDC Roaming Partners by Country
| Country | Primary Network Operator(s) |
| United States | AT&T, T-Mobile |
| Brazil | Vivo |
| Russia | Beeline |
| United Kingdom | O2, Vodafone |
| India | Airtel |
| South Korea | SK Telecom |
| Germany | O2 |
| Sweden | Tele2, Telia |
| Iran | MTN Irancell |
My Steps to Stay Connected While Roaming
I’ve fine-tuned a checklist that ensures I never lose mobile data access while traveling.
1. Activate Data Roaming
I make sure data roaming is enabled before I land in another country:
- Open Settings > Connections > Mobile Networks.
- Toggle Data Roaming ON.
2. Double-Check APN Settings
I always verify that my APN settings are correct:
- Go to Settings > Mobile Network > Access Point Names.
- Ensure the APN is set to internet.
- Keep Username and Password blank.
- Save the APN and select it as active.
3. Manually Select the Right Network (If Needed)
Most of the time, my phone automatically connects to a roaming partner. But if my internet is slow or I can’t connect, I switch to manual mode:
- Open Settings > Mobile Networks > Network Operators.
- Turn OFF automatic selection.
- Manually choose one of the primary network operators from the table above.
After fixing my TDC APN settings, my internet became noticeably faster and more stable. If you’re experiencing issues, double-check your APN settings, try alternative configurations, and manually adjust your network band if needed. Don’t forget to save your current settings before making changes!
Conclusion
When I travel abroad using TDC (Tele Danmark Communications) services, I always make sure my device is set up correctly for international roaming. In most cases, TDC uses the same APN settings for both domestic and international networks, but I’ve learned that some tweaks might be needed depending on the country and local network partners. Here’s how I ensure a smooth mobile experience while roaming.
