On Arrival

Turning on your eSIM at Copenhagen Kastrup (CPH)

When to turn on your eSIM

Activate your eSIM after clearing customs at Copenhagen Kastrup (CPH), before you leave the terminal. Do not enable it during a layover at a connecting airport. Most plans start counting from the first network connection, not from installation. Enabling during transit burns a full day of your plan.

Connecting to TDC/Nuuday's network

  1. Open Settings on your phone
  2. Go to Cellular (iPhone) or Network & Internet (Android)
  3. Select your travel eSIM line
  4. Enable Data Roaming on that line only
  5. Wait 2-3 minutes for TDC/Nuuday's 5G network to register

Expected speeds on TDC/Nuuday: approximately 203 Mbps download.

Airport WiFi as backup

Copenhagen Kastrup (CPH) offers reliable free WiFi. Use it as a backup to complete eSIM installation if you did not set up at home. Airport WiFi often requires a phone number to register, so installing at home is the safer option.

What if your eSIM does not connect

  1. Toggle Data Roaming off and back on
  2. Restart your phone
  3. Verify the travel eSIM is selected as your cellular data line
  4. Try manual network selection: choose TDC/Nuuday
  5. For emergencies, dial 112

Configuration

Network and SIM configuration in Denmark

Dual-SIM configuration

Keep your home SIM for calls and texts. Set the travel eSIM as your cellular data line. On iPhone: Settings > Cellular > Cellular Data > select travel eSIM. On Android: Settings > Network & Internet > SIMs > set travel eSIM for mobile data. iMessage and FaceTime should stay on your home number.

Data roaming settings

Enable data roaming on the travel eSIM line only. Disable data roaming on your home SIM to prevent carrier charges. On iPhone: Settings > Cellular > select home SIM > Data Roaming OFF. On Android: Settings > Network > SIMs > home SIM > Roaming OFF.

APN configuration

Most eSIMs auto-configure APN settings for TDC/Nuuday. Verify in Settings > Cellular > Cellular Data Options > Cellular Data Network. If auto-configuration fails, check your provider's email for manual APN values. Manual entry is rare but occasionally needed on older Android devices.

Troubleshooting

Denmark eSIM not working: what to check

SIM registration and ID requirements

ID required for all SIM purchases including prepaid With a prepaid eSIM, the provider handles registration remotely. You do not need to visit a counter or present your passport in person.

Speed and coverage in rural areas

TDC/Nuuday provides the broadest coverage in Denmark, but speeds drop outside major cities. Urban areas average 203 Mbps. Rural areas may see 5-15 Mbps on LTE. 5G is available in select areas (widespread).

Common error messages

"eSIM not supported"
Your phone is carrier-locked. Contact your home carrier to unlock (24-72 hours).
"No service"
Data roaming is off on the travel eSIM line. Enable it in Settings.
"Plan expired"
The plan was activated too early (during a layover). Contact the provider for a replacement.
"Unable to activate"
eSIM profile slot is full. Delete unused profiles in Settings > Cellular. iPhones hold 8 profiles (2 active).

Installation Methods

Denmark eSIM installation methods compared

QR Code Scan Method

  1. Purchase your Denmark eSIM from any provider (Airalo, Holafly, Saily, Nomad). The QR code arrives via email or is displayed in your account dashboard.
  2. Display the QR code on a separate screen — laptop, tablet, or a printed copy. You cannot scan a QR code on the same phone you are installing the eSIM on.
  3. On your phone: iPhone — Settings > Cellular > Add eSIM > Use QR Code. Samsung — Settings > Connections > SIM Manager > Add eSIM > Scan QR Code. Pixel — Settings > Network & Internet > SIMs > Add SIM > Download SIM.
  4. Point your camera at the QR code. The eSIM profile downloads in 5-15 seconds over WiFi.
  5. Tap "Activate" or "Add" when prompted. Label the plan "Denmark Data."
  6. Disable the eSIM after installation. Enable it after landing at Copenhagen Kastrup (CPH).

Pros:

  • Works with any eSIM provider — universal method across all platforms.
  • No app installation required — uses your phone's built-in Settings flow.
  • The QR code is a one-time-use credential: once scanned, the profile is on your device permanently (until you delete it).
  • Faster initial setup: scanning takes 10 seconds vs app download + account creation.

Cons:

  • Requires a second screen to display the QR code — cannot scan from the same device.
  • Requires WiFi or mobile data for the download.
  • If the scan fails, you need the SM-DP+ manual entry code from the confirmation email as a fallback.
  • QR codes are single-use for most providers — losing the email before scanning means contacting support.

Best for: Travelers installing at home before departure, users who prefer not to install additional apps, and anyone setting up a Denmark eSIM on a secondary phone or tablet.

Provider App Installation

  1. Download your provider's app: Airalo (iOS/Android), Holafly (iOS/Android), Saily (iOS/Android), or Nomad (iOS/Android).
  2. Create an account or sign in. Search for "Denmark" in the destination field.
  3. Select and purchase your plan. Plans start at $2.84 for 1GB.
  4. The app presents an "Install" button for your Denmark plan. Tap it. The app opens your phone's native eSIM settings and guides you through the process.
  5. Follow the on-screen prompts. The app handles QR code scanning internally — no second screen needed.
  6. After installation, the app shows your plan status: data remaining, validity period, and connected carrier (TDC/Nuuday in Denmark).

Pros:

  • No second screen needed — the app handles the QR scanning or direct provisioning internally.
  • Built-in plan management: monitor data usage, check validity, and view carrier connection status.
  • Easier reactivation: if you visit ${country.name} again, the app stores your purchase history.
  • Some apps (Airalo, Saily) support direct eSIM provisioning — no QR code needed at all.

Cons:

  • Requires downloading a 50-100 MB app before installation — uses storage and initial data.
  • Account creation adds 2-3 minutes to the process.
  • Each provider has a separate app — managing plans across Airalo, Holafly, and Saily means three apps.
  • App updates can temporarily break the installation flow on older OS versions.

Best for: First-time eSIM users who want guided setup, travelers who buy from the same provider regularly, and anyone who wants in-app data monitoring during their Denmark trip.

Recommendation: The QR code method is faster by 2-3 minutes. The app method is safer for first-time eSIM users. For Denmark, neither method affects which carrier you connect to (TDC/Nuuday's 5G/LTE network) or the plan price. Choose based on whether you want a guided flow (app) or a quick setup (QR). Install before departure regardless — airport WiFi at Copenhagen Kastrup (CPH) is not reliable enough for eSIM downloads.

Timing

Denmark eSIM setup timing: install at home or at Copenhagen Kastrup (CPH)?

Pre-Departure Setup (Recommended)

Home installation removes every variable: reliable WiFi, no time pressure, full concentration. Add the Denmark eSIM, label it, set it as your data line, and disable it. On landing at Copenhagen Kastrup (CPH), one Settings toggle puts you on TDC/Nuuday's 5G/LTE network. Total post-landing time to data: under 2 minutes.

Pros:

  • Reliable WiFi at home — no captive portals or unstable airport networks.
  • No time pressure. If the QR code fails, you have hours to contact support.
  • Jet-lag-free setup. Configuring Settings after a 12-hour flight leads to mistakes.
  • Immediate data on landing: TDC/Nuuday connects in 60-90 seconds, no WiFi search.
  • No SIM counter detour at Copenhagen Kastrup (CPH) — skip the 5-10 min queue and $10-20 for 5-10GB / 28 days tourist markup.
  • Plan timer does not start until TDC/Nuuday registers the profile — no wasted days.

Cons:

  • Must remember to install before departure — not an option if you forget.
  • Plan validity begins on first network connection, not purchase date — but activating during a layover still burns a day.
  • If you change your travel dates after installation, the eSIM sits unused until you travel.

Choose when: Best for: all planned trips. Install 24-48 hours before departure.

On-Arrival Setup at Copenhagen Kastrup (CPH)

Setting up at Copenhagen Kastrup (CPH) after landing adds 5-15 minutes to your arrival process. WiFi is needed for the QR scan. Airport WiFi is adequate. If the scan fails, you fall back to manual SM-DP+ entry — typing a long server address on a phone after hours of travel. SIM counter alternative: $10-20 for 5-10GB / 28 days, 5-10 min wait.

Pros:

  • Plan timer starts immediately after first connection — no risk of accidental activation during layovers.
  • No advance planning needed — works for last-minute trips.
  • SIM counter at Copenhagen Kastrup (CPH) provides a physical backup option ($10-20 for 5-10GB / 28 days).

Cons:

  • Requires WiFi for QR scan.
  • Jet-lag mistakes: wrong data line, roaming left off, APN entry errors.
  • 5-15 minutes of setup time at the airport instead of immediate data.
  • SIM counter costs $10-20 for 5-10GB / 28 days with a 5-10 min queue — your only alternative if the eSIM download fails.
  • Physical SIM requires ID required for all SIM purchases including prepaid — adds 15-30 minutes.

Choose when: Best for: last-minute trips where pre-departure setup was not possible.

Verdict: Set up before you fly. On-arrival installation only makes sense for truly last-minute trips where you booked the flight hours ago. For any planned travel to Denmark, home installation is faster, safer, and free of airport friction. Data is active before you reach the taxi stand.

Post-activation checklist for Denmark

eSIM verification checklist for Denmark
StepWhat to checkIf it fails
Check carrier name in status barYour status bar should display "TDC/Nuuday" or "Telia DK" within 60-90 seconds of enabling the eSIM. The 5G/LTE indicator confirms your connection type.If "No Service" or "Searching..." persists after 2 minutes: Settings > Cellular > Network Selection > turn off Automatic, wait 10 seconds, turn it back on. If TDC/Nuuday does not appear, restart your phone.
Verify data line assignmentOpen Settings > Cellular > Cellular Data. Confirm the Denmark eSIM is selected as the active data line. If your home SIM is selected, all data routes through your home carrier at roaming rates.Tap "Cellular Data" and select the Denmark eSIM. Disable "Allow Cellular Data Switching" to prevent automatic fallback to your home SIM when TDC/Nuuday's signal dips briefly.
Confirm data roaming is enabledSettings > Cellular > [Denmark eSIM] > Data Roaming must be ON. Most travel eSIM plans route through roaming agreements — data roaming must be enabled for the travel line specifically.Toggle Data Roaming ON for the Denmark eSIM line only. Leave roaming OFF on your home SIM to prevent accidental charges.
Load a webpage to verify data flowOpen Safari or Chrome and load any webpage. If the page renders within 3 seconds, your Denmark eSIM is delivering data on TDC/Nuuday's 5G/LTE network. Slow loads (10+ seconds) indicate APN misconfiguration.If the page does not load: check Settings > Cellular > Cellular Data Network for APN settings. If blank, contact your eSIM provider for the correct APN string for TDC/Nuuday's network in Denmark.
Test messaging appsOpen WhatsApp, Telegram, or iMessage and send a test message. If it delivers within seconds, your data connection is working. Voice and video calls over these apps also work in Denmark.If messages do not send, verify your data line assignment (step 2) and data roaming status (step 3). Both must be correctly configured.
Verify emergency dialing capabilityEmergency calls to 112 work from any active SIM in Denmark, even without data. With eSIM data active, your phone's emergency SOS feature also shares your GPS location with responders.Emergency calls bypass SIM restrictions. If your eSIM has no data, the call still connects through any available network. Store 112 in your phone contacts as "Denmark Emergency."
Check remaining data balanceOpen your eSIM provider's app (Airalo, Holafly, Saily, or Nomad) and verify your remaining data and validity period. The plan timer started when TDC/Nuuday first registered your profile.If the app shows zero data remaining immediately after activation, the plan may have been activated during a layover. Contact your provider's support for a replacement or top-up.

Data Tips

Save data on your Denmark eSIM: practical tips

Download offline maps before departure

Google Maps and Maps.me allow offline downloads for specific regions. Download Denmark's major cities before leaving WiFi. Offline maps use zero cellular data for navigation. A single city map is 50-200 MB — download at home, not on your eSIM.

Disable background app refresh

Go to Settings > General > Background App Refresh (iPhone) or Settings > Battery > Background Usage Limits (Samsung). Background refresh consumes 200-500 MB per day without visible activity. Social media apps, news feeds, and email clients refresh constantly. Disable all except essential apps while on your Denmark eSIM.

Pause cloud sync and auto-backups

iCloud Photos, Google Photos, and cloud backup services upload images and videos over cellular data. A single day of vacation photos can consume 1-3 GB in background uploads. Pause cloud sync: iPhone — Settings > Photos > Cellular Data > toggle off. Android — Google Photos > Settings > Back up & sync > Use cellular data > off. Sync manually over WiFi at your hotel each evening.

Use WiFi when available

Denmark has excellent public WiFi. Free WiFi in cafes, libraries, and DSB trains. Use hotel and cafe WiFi for data-heavy tasks: video calls, software updates, large downloads, and cloud sync. Reserve your eSIM data for on-the-go navigation and messaging.

Set video quality to low on streaming apps

Standard definition video uses about 700 MB per hour. HD uses 1.5-3 GB. If you stream on your Denmark eSIM, set Netflix, YouTube, and other apps to "Data Saver" or "Low" quality. Better approach: download episodes over WiFi before going out.

Monitor data usage in real time

iPhone: Settings > Cellular > scroll to usage stats for each app. Samsung: Settings > Connections > Data Usage > Mobile Data Usage. Check daily. Set a data warning at 80% of your plan limit: iPhone uses Screen Time limits; Samsung has a built-in data warning under Data Usage settings. Your eSIM provider's app also shows remaining data for your Denmark plan.

Peak season data note: Jun-Aug

During Jun-Aug, TDC/Nuuday's network carries heavier traffic in tourist areas. Network congestion increases retransmission overhead, meaning your phone uses 10-20% more data per webpage load. Budget a slightly larger plan during peak months.

Business

Managing corporate eSIMs for Denmark business trips

For Denmark business trips, an eSIM replaces the traditional corporate SIM procurement process. No vendor contract, no physical card shipping, no IT desk setup. Each traveler purchases and installs their own Denmark eSIM in under 10 minutes. TDC/Nuuday's 5G/LTE network provides 203 Mbps average, and plans include hotspot for laptop connectivity.

Multi-device management

One eSIM per device, no sharing. For a Denmark team trip, purchase plans individually or through Airalo's business portal. Each traveler installs their own QR code before departure. Label profiles clearly: "Denmark - [Name]" prevents confusion when multiple eSIMs are active on managed devices. MDM-enrolled phones: check that your IT policy permits third-party eSIM profiles alongside the corporate SIM.

VPN and security

No VoIP blocks in Denmark. Your corporate VPN and all video conferencing tools work on TDC/Nuuday's 5G/LTE network at 203 Mbps average. Split-tunnel your VPN if possible: route corporate traffic through VPN, let general browsing use the direct eSIM connection. This reduces data consumption and improves call quality.

Expense tracking

For expense reporting, save the eSIM purchase confirmation email. It contains all required fields: provider name, destination (Denmark), plan details, USD price, and date. Most corporate expense tools accept this as a digital receipt under "Travel Communications." eSIM costs are fixed and predictable — no surprise overages at month-end.

Emergency protocol

Before traveling to Denmark, save these numbers: 112 (local emergency), your corporate travel security hotline, and your insurance provider's international number. With eSIM data on TDC/Nuuday, you have access to maps, translation apps, and real-time communication with your company's crisis team. Keep your home SIM active as a backup voice line.

Transfer

Transfer your Denmark eSIM to a new phone

If you need to move your Denmark eSIM to a different phone — due to a phone replacement, upgrade, or device failure — the process depends on your device and provider. Some transfers work directly between phones. Others require contacting your provider for a new QR code. The eSIM profile on TDC/Nuuday's 5G/LTE network transfers with your remaining data and validity intact.

iPhone to iPhone

iPhone to iPhone (iOS 17+): Settings > Cellular > tap the Denmark eSIM > Transfer to Nearby iPhone. Both phones must be within Bluetooth range, signed into the same Apple ID, and running iOS 17 or later. The transfer takes 2-5 minutes. Your TDC/Nuuday connection resumes on the new device within 60 seconds. Quick Start during initial setup also offers eSIM transfer as part of the migration flow.

Android transfer

Samsung to Samsung or Pixel to Pixel: most Android manufacturers do not support direct eSIM transfer between devices. You need a new QR code from your eSIM provider. Contact Airalo (in-app chat, 4 min avg), Holafly (WhatsApp +34 644 44 37 97), or Saily (email support) and request a profile reissue for your Denmark plan. The provider deactivates the old profile and issues a new QR code for the new device. Your remaining data and validity transfer to the new profile.

Cross-platform

iPhone to Android or Android to iPhone: cross-platform eSIM transfer requires provider intervention. Contact your provider's support, explain the device change, and request a new QR code. The Denmark plan (remaining data and validity on TDC/Nuuday's 5G/LTE network) transfers to the new profile. Install the new QR code on the replacement device, configure the data line, and enable roaming. TDC/Nuuday registers in 60-90 seconds.

Warning: Do not delete the eSIM profile from your old device before confirming the transfer or receiving a new QR code. Deletion without a backup code may permanently deactivate the profile. Contact your provider first, complete the transfer process, and only then remove the old profile.

After Your Trip

After your Denmark trip: eSIM cleanup

  1. Disable the Denmark eSIM immediately: Settings > Cellular > [Denmark Data] > turn off "Turn On This Line."
  2. Re-enable your home SIM as the primary data line: Settings > Cellular > Cellular Data > select your home SIM.
  3. Turn off data roaming on all lines: Settings > Cellular > each line > Data Roaming > Off.
  4. Check your Denmark data usage in your provider app — note remaining balance for records or potential refund.
  5. Decide whether to keep or delete the Denmark eSIM profile (see guidance below).

If you plan to visit Denmark again within 6 months, keep the eSIM profile on your phone. It occupies zero storage and does not affect performance. You can purchase a new plan and apply it to the existing profile without re-scanning a QR code. If the trip was a one-time visit, delete the profile: Settings > Cellular > [Denmark eSIM] > Remove Cellular Plan. This frees an eSIM slot for future destinations. iPhones hold up to 8 profiles.

Quick Answers

Common questions about eSIM in Denmark

FAQ

FAQ: traveling with eSIM in Denmark

When should I activate my eSIM for Denmark?

Activate your eSIM after you land and clear customs at Copenhagen Kastrup (CPH). Do not enable it during a layover because most plans start counting from the first network connection. Keep the eSIM toggled off until you reach Denmark.

Does my eSIM work at Copenhagen Kastrup (CPH)?

Yes. TDC/Nuuday's network covers Copenhagen Kastrup (CPH) and surrounding areas. After clearing customs, open Settings, select your travel eSIM, and enable data roaming. Your phone connects to TDC/Nuuday within 2-3 minutes.

How much data do I need for 4 days in Denmark?

Most travelers use 500 MB to 1.5 GB per day for maps, messaging, and light browsing. For a 4-day trip, a 3GB plan covers typical usage. Heavy streaming or video calls require more. Plans start at $2.84 for 1GB.

Can I use WhatsApp and FaceTime with my eSIM in Denmark?

Yes. WhatsApp, FaceTime, and other data-based messaging apps work on all eSIM data plans in Denmark. No VoIP restrictions apply in Denmark.

What if my eSIM stops working during my trip in Denmark?

Toggle data roaming off and back on. Restart your phone. Verify the travel eSIM is selected as your cellular data line in Settings. If the issue persists, try manual network selection and choose TDC/Nuuday. For emergencies, dial 112.

Is WiFi reliable enough in Denmark to skip an eSIM?

WiFi in Denmark is excellent in hotels and cafes, but relying on WiFi alone leaves you without navigation, ride-share apps, and emergency access between hotspots. A prepaid eSIM keeps you connected everywhere, with WiFi as a data-saving supplement.

Do I need to register my eSIM in Denmark?

Denmark requires SIM registration for physical SIM cards. ID required for all SIM purchases including prepaid eSIM providers handle registration on your behalf, so you do not need to visit a counter or provide ID in person.
