Why Is My eSIM Slow in the Netherlands?

A slow Netherlands eSIM does not always mean that the service is faulty. Mobile data performance can change depending on your location, indoor signal, network congestion, phone settings and the conditions of your data plan.

Busy airports, railway stations, festivals and central Amsterdam locations may temporarily have slower speeds because many people are connected to the same mobile network. Weak indoor coverage or an unstable 5G connection can also make websites and apps load slowly.

Quick fix: move outdoors or closer to a window, switch from 5G to 4G/LTE, pause background downloads and turn Airplane Mode on for 30 seconds. Confirm that the Netherlands eSIM is selected for Mobile Data and that Data Roaming is enabled.

Common Reasons Your Netherlands eSIM Is Slow

Possible Cause	What to Do
Weak indoor signal	Move outdoors or closer to a window
Network congestion	Wait and test again from another location
Unstable 5G	Switch to 4G/LTE
Background downloads	Pause updates, backups and synchronisation
Hotspot usage	Disconnect unnecessary devices
Incorrect data settings	Check Mobile Data, roaming and APN
Fair-use limit reached	Wait for the next daily high-speed reset

1. Check Your Signal Strength

Mobile data is often slower inside historic buildings, basement restaurants, museums, railway tunnels and hotels with thick walls.

Try moving:

• Closer to a window.
• Outside the building.
• Away from underground areas.
• To another part of the station or airport.

If the connection improves outdoors, the problem is likely local indoor coverage rather than the eSIM itself.

2. Switch from 5G to 4G/LTE

A weak 5G signal can be slower and less stable than a strong 4G connection. The phone may repeatedly switch between 5G and LTE, interrupting downloads and app connections.

Switch temporarily to 4G/LTE when:

• The mobile data icon constantly changes.
• Pages load intermittently.
• The connection drops during train journeys.
• 5G appears but apps remain slow.
• You are inside a building with weak reception.

Stable 4G/LTE is sufficient for maps, WhatsApp, public transport apps, email, browsing and most video calls.

3. Refresh the Mobile Network

A simple network refresh can help the phone reconnect to a better available signal.

1. Turn Airplane Mode on.
2. Wait 30 seconds.
3. Turn Airplane Mode off.
4. Wait several minutes for reconnection.
5. Restart the phone if the speed remains poor.

Keep Network Selection on Automatic unless customer support instructs you to choose an operator manually.

4. Check the Correct Mobile Data Settings

Setting	Recommended Value
Netherlands eSIM	Enabled
Mobile Data	Netherlands eSIM
Data Roaming on travel eSIM	On
Data Roaming on primary SIM	Off
Automatic Data Switching	Off
Network Selection	Automatic
Preferred Network	4G/LTE when 5G is unstable

Automatic Data Switching should remain off because the phone may otherwise move data back to your primary SIM and create roaming charges.

5. Pause Background Data Usage

Your phone may be using significant data in the background even when you are not actively downloading anything.

Temporarily pause:

• Cloud photo and video backups.
• Application updates.
• Operating-system downloads.
• Email attachment synchronisation.
• Offline media downloads.
• Automatic social media uploads.

Use Low Data Mode on iPhone or Data Saver on Android to reduce unnecessary background activity.

6. Check Personal Hotspot Usage

A laptop or tablet connected through Personal Hotspot can consume data quickly through software updates, cloud storage and video meetings.

To improve performance:

• Disconnect unused devices.
• Set the laptop connection as metered.
• Pause cloud synchronisation.
• Reduce video-call quality.
• Close unnecessary browser tabs and streaming apps.

Hotspot availability depends on the selected plan and device settings.

7. Check Whether a Fair-Use Limit Has Been Reached

NoveSIM unlimited plans provide 1 GB of high-speed data per 24-hour period. After that allowance is used, the connection may continue at a reduced speed until the next daily reset.

Activities that can use 1 GB quickly include:

• High-definition video streaming.
• Long video calls.
• Cloud photo backups.
• Large application downloads.
• Personal Hotspot use.

A reduced speed after intensive usage may therefore be part of the plan’s fair-use policy rather than a network problem.

8. Check the APN

An incorrect APN more commonly causes no internet, but it can also produce an unstable connection. When manual configuration is required, use:

Field	Value
Name	NoveSIM
APN	data.esim
Username	Leave blank
Password	Leave blank
Authentication	None

Save the APN and make sure it is selected for the Netherlands eSIM.

See the Netherlands eSIM APN settings.

Why Is the eSIM Slow in Amsterdam?

Amsterdam generally has strong mobile coverage, but performance may decrease in crowded or difficult indoor locations.

Temporary slowdowns are more likely around:

• Amsterdam Central Station.
• Schiphol Airport during busy periods.
• Large festivals and events.
• Crowded tourist attractions.
• Underground or thick-walled buildings.

Move a short distance, switch to LTE and test again before changing advanced settings.

Why Is the eSIM Slow on Dutch Trains?

Mobile data can become unstable while the train moves between network towers. Signal may also weaken in tunnels, underground stations and rural sections of the route.

For more reliable travel:

• Download tickets before boarding.
• Save hotel details offline.
• Download an offline map.
• Use 4G/LTE when 5G repeatedly disconnects.

How to Test the Connection Properly

1. Turn off WiFi.
2. Close background downloads.
3. Move to an area with a strong signal.
4. Open a new webpage.
5. Test maps or messaging.
6. Repeat the test after switching between 5G and LTE.

A single slow application does not always indicate slow mobile data. The application itself may be experiencing a temporary service problem.

Should You Manually Select a Network?

Keep Network Selection on Automatic in normal use. Manual network selection can help only when the eSIM repeatedly connects to a weak partner network and customer support confirms that another supported network is available.

Do not select random networks repeatedly, as unsupported networks may reject the connection.

Should You Delete the eSIM?

No. Do not delete the Netherlands eSIM while troubleshooting slow data. The QR code may be valid for one installation only.

First try:

• Moving to another location.
• Switching to 4G/LTE.
• Using Airplane Mode for 30 seconds.
• Pausing background data.
• Checking the fair-use allowance.
• Restarting the phone.

When to Contact Customer Support

Contact support when the connection remains consistently slow in several locations after completing the basic checks.

Include:

• Your order number.
• Your phone model.
• Your current city.
• The signal icon shown on the phone.
• Whether the issue occurs on 5G, LTE or both.
• Screenshots of the eSIM settings.

FAQ

Why is my eSIM slow in the Netherlands?

Common causes include weak indoor signal, network congestion, unstable 5G, background downloads or a reached high-speed fair-use allowance.

Should I switch from 5G to 4G?

Yes, when 5G is weak or unstable. A strong LTE connection may be faster and more reliable.

Why is mobile data slow at Schiphol Airport?

Large numbers of connected travellers can temporarily increase network congestion, especially during busy periods.

Can cloud backups slow down the connection?

Yes. Photo uploads, application updates and cloud synchronisation can use much of the available bandwidth.

Does unlimited data always mean unlimited high-speed data?

No. NoveSIM unlimited plans include 1 GB of high-speed data per 24-hour period, followed by possible reduced speed until the next reset.

What APN should I use?

Use data.esim when manual APN configuration is required.

Should I delete and reinstall the eSIM?

No. The QR code may support only one installation. Try the network and device troubleshooting steps first.

Final Recommendation

When your Netherlands eSIM is slow, first move to an area with a stronger signal and switch from unstable 5G to 4G/LTE.

Pause cloud backups, application updates and hotspot connections. Refresh the network with Airplane Mode for 30 seconds and confirm that the travel eSIM is selected for Mobile Data.

If you use an unlimited NoveSIM plan, remember that it includes 1 GB of high-speed data per 24-hour period. Speed may be reduced after that allowance until the next daily reset.

Do not delete the eSIM during troubleshooting. Contact support when the connection remains slow across several locations and on both 5G and LTE.
