eSIM Not Working in Europe? 9 Proven Fixes That Work

Your eSIM was supposed to just work. It didn’t. Here are 9 fixes, starting with the one that solves it 90% of the time.

You landed in Europe, opened your phone, and nothing. No signal, no data, no connection. Or maybe it worked for an hour and then dropped. Or it’s showing a carrier name but no data is actually moving. Whatever the symptom, the fix is usually simpler than you think — and it’s almost never a problem with the eSIM itself.

The best eSIM for Europe means nothing if your eSIM is not working in Europe because of a simple configuration issue. These 9 fixes cover almost every reason an eSIM stops working when you land in Europe, in order of how often they actually solve the problem.

Most travelers searching for eSIM not working in Europe are dealing with one of the fixes below — usually Fix 1, 3, or 4.

Why eSIM Not Working in Europe Happens (Common Causes)

How to use this guide: Start at Fix 1 and work down. Most people solve it by Fix 3.

Fix 1: Toggle Airplane Mode Off and On

Solves: ~40% of eSIM connection failures

This is the fix. Before anything else — turn Airplane Mode on, wait 10 seconds, turn it off. This forces your phone to re-scan available networks and re-register your eSIM on the local carrier.

Why it works: When you land in a new country, your phone tries to latch onto the strongest available signal. Sometimes it locks onto a network your eSIM doesn’t support, or fails to register at all after the flight. Airplane Mode forces a full network reset without rebooting the device.

How to do it:

iPhone: Settings → Airplane Mode ON → wait 10 seconds → OFF
Android: Pull down notification shade → Airplane Mode ON → wait 10 seconds → OFF

If you still have no signal after this, move to Fix 2. If you have signal but no data, skip to Fix 4.

Fix 2: Restart Your Phone Completely

Solves: ~20% of remaining failures after Fix 1

A full restart clears cached network states that Airplane Mode sometimes doesn’t touch. Power the phone completely off — not just lock screen — wait 30 seconds, power back on.

iPhone: Hold side button + volume down → slide to power off → wait 30s → power on. Android: Hold power button → Restart (or Power Off → wait → Power On).

After restart, give the phone 60 seconds to find and register on the network before assuming it hasn’t worked. Network registration after a cold boot takes longer than most people expect.

Fix 3: Check That Your eSIM Is Set as the Active Data Line

Solves: The most common “I have signal but no data” problem

This is the fix that catches most people out. On dual-SIM phones, data defaults to your physical SIM — not your eSIM. Your eSIM may be installed and registered correctly, but data is routing through the wrong line.

iPhone:

Settings → Mobile Data (or Cellular)
Tap “Mobile Data” at the top
Select your eSIM line (Nomad, Airalo, Holafly, etc.)
Also check: Settings → Mobile Data → [your eSIM line] → Turn On This Line

Android (Samsung):

Settings → Connections → SIM Card Manager
Confirm your eSIM is toggled ON
Mobile Data → select your eSIM

Android (Google Pixel):

Settings → Network & Internet → SIMs
Confirm eSIM is active and set as preferred for data

If you have a physical SIM from your home country still inserted, remove it or manually set data to the eSIM. This single step resolves the majority of “eSIM installed but not working” reports.

Fix 4: Enable Data Roaming for Your eSIM Line

Solves: Signal showing but zero data moving

Even though you’re using a travel eSIM — not your home carrier — iOS and Android still require Data Roaming to be enabled for the eSIM line to use local networks abroad. This catches many travelers who assume roaming settings only apply to home SIMs.

iPhone:

Settings → Mobile Data → [your eSIM plan name]
Toggle Data Roaming ON

Android:

Settings → Connections → Mobile Networks
Select your eSIM line
Toggle Data Roaming ON

This is distinct from your home carrier’s roaming charges — enabling this setting on a Nomad, Airalo, or Holafly eSIM costs nothing extra. It simply tells the phone to allow the eSIM to connect to foreign networks, which is exactly what a travel eSIM is designed to do.

Fix 5: Select the Network Manually

Solves: “No Service” in areas where signal should exist

Sometimes automatic network selection latches onto a carrier your eSIM doesn’t support. Manual selection forces it onto the correct one.

Find your eSIM’s carrier first: Check your confirmation email or the provider’s app — it lists which carrier your eSIM uses in each country. For example:

Nomad in Germany → Telekom / Vodafone DE
Holafly in France → Orange France
Airalo in Italy → TIM / WindTre

iPhone:

Settings → Mobile Data → [eSIM line] → Network Selection
Toggle Automatic OFF
Wait for network scan → select your carrier from the list
Toggle back to Automatic after it connects

Android:

Settings → Connections → Mobile Networks → Network Operators
Search networks → select your carrier manually

Important: After manually connecting, switch back to Automatic. Leaving it on manual means the phone won’t switch if you move to an area where that carrier is weak.

If your eSIM is not working in Europe after Fixes 1–5, the issue is almost certainly in the settings below — APN, data plan, or the eSIM profile itself.

If you searched for “eSIM not working in Europe”, the remaining causes are usually APN configuration, an expired data plan, or a corrupted eSIM profile.

Fix 6: Check Your APN Settings

Solves: Data issues on Android; rare on iPhone but possible

APN (Access Point Name) is the configuration that tells your phone how to connect to your provider’s data network. Most eSIMs configure this automatically — but on Android, it sometimes needs to be set manually.

How to check (Android):

Settings → Connections → Mobile Networks → Access Point Names
Look for an APN entry from your eSIM provider
If missing: tap “+” and enter the APN details from your provider’s support page

Nomad APN: Usually auto-configured. If not: APN = internet, no username/password required. Airalo APN: Auto-configured via eSIM profile. If issues persist, check airalo.com/support. Holafly APN: Auto-configured. Support page: esim.holafly.com/support.

iPhone note: APN settings on iPhone are locked when using eSIM profiles — you cannot and do not need to edit them manually. If your iPhone has an APN issue, it points to a deeper profile problem (see Fix 8).

Fix 7: Check Your Data Plan — It May Have Expired or Run Out

Solves: eSIM that was working and then stopped

Before assuming a technical fault, check the basics: is your plan still active? eSIM plans expire in two ways — by date or by data exhaustion.

Check remaining data:

Nomad: Nomad app → My eSIMs → Usage
Airalo: Airalo app → My eSIMs → [plan] → Data Balance
Holafly: Holafly app → Active Plans

Common expiry traps:

Nomad “Unlimited” plans: throttled to 512kbps after 2GB/day — feels like no data but is technically still connected
Holafly: Fair Use Policy — speed may reduce after heavy usage; the plan hasn’t expired, it’s throttled
Day-based plans: a “7-day” plan starts counting from first activation (first network connection), not from purchase date

If your plan has expired, you can purchase a new eSIM — you don’t need to reinstall anything on iPhone. On Android, some providers require a new QR code for a new plan.

Fix 8: Delete and Reinstall the eSIM Profile

Solves: Corrupted eSIM installation; last resort before support

If all previous fixes have failed, the eSIM profile itself may be corrupted — a rare but real occurrence, usually caused by a failed download or interrupted installation.

⚠️ Warning: Deleting an eSIM removes it permanently from the device. Before doing this, confirm with your provider that you can re-download. Most providers (Nomad, Airalo, Holafly) allow one re-download — but not all, and not always.

Contact your provider first and ask: “Can I re-download my eSIM if I delete it?” Get written confirmation before proceeding.

iPhone:

Settings → Mobile Data → [eSIM line]
Scroll down → Remove Mobile Plan
Re-install via QR code or provider app

Android:

Settings → Connections → SIM Card Manager → [eSIM]
Delete → confirm
Re-install via QR code

After reinstall, go through Fixes 3 and 4 again — Data Roaming and active data line settings reset when you reinstall.

Fix 9: Check eSIM Compatibility With Your Specific Phone Model

Solves: eSIM that never worked at all from the start

Not all phones support all eSIM implementations. Even if your phone officially supports eSIM, specific models have known issues with certain providers or network bands.

Known compatibility issues:

iPhone bought in the USA before 2023: Some US-purchased iPhones are carrier-locked or have different band support than European models. Check Apple’s official eSIM support page to verify your model’s eSIM capabilities before contacting your provider.
Android phones with single eSIM slot used: Some Android devices have one physical SIM and one eSIM — but if the physical SIM is inserted, the eSIM slot may be disabled in firmware. Try removing the physical SIM.
Older Android models (pre-2020): eSIM support varies dramatically by manufacturer and firmware version. Check your exact model on your provider’s compatibility page.

Quick compatibility check:

Airalo: airalo.com/esim-supported-devices
Nomad: nomadesim.com/shop/support_device

At this stage, most travelers dealing with eSIM not working in Europe issues have already ruled out basic phone settings and should verify device compatibility or provider configuration.

FAQ

Why is my eSIM showing signal but not loading data?

The most common cause: Data Roaming is disabled for the eSIM line (Fix 4), or your physical SIM is set as the active data line instead of the eSIM (Fix 3). Check both settings before anything else. If both are correct and data still isn’t moving, check your APN settings (Fix 6) or verify your plan hasn’t run out (Fix 7).

Why did my eSIM stop working after a few hours?

Three likely causes: your daily data cap was reached and speed throttled to unusable levels (check Fix 7), the network you were connected to dropped and the phone failed to switch (try Fix 1 and Fix 5), or your plan expired earlier than expected because the timer started at first activation rather than purchase. Check your data balance in the provider app first.

Can I fix eSIM problems without Wi-Fi?

Fixes 1, 2, 3, 4, and 5 require no internet connection — they’re all phone settings adjustments. Fix 6 (APN) can be done offline on Android. Fix 7 requires the provider app, which needs Wi-Fi or data to load. If you have no connectivity at all, find a café with Wi-Fi, check your plan status, and then work through the offline fixes.

My eSIM worked in one country but stopped in another — why?

Your eSIM plan may not cover the second country. Country-specific plans (e.g., a France-only eSIM) don’t roam into neighbouring countries. Check your plan’s country coverage in the provider app. If you need multi-country coverage, a European regional plan from Nomad, Airalo, or Holafly covers 35–42 countries. See my guide to eSIM for multiple European countries.

Do I need to delete my home SIM to use a travel eSIM?

No — but you may need to manually set your travel eSIM as the active data line (Fix 3). On dual-SIM phones, the physical SIM is usually the default for data. You can keep both installed and switch data between them in settings. If your home carrier SIM is causing network conflicts, toggling it off (without removing it) usually resolves the issue.

Is it safe to delete and reinstall my eSIM?

Only if your provider confirms you can re-download it. Most major providers (Nomad, Airalo, Holafly) allow one re-download per plan, but policies vary. Contact support before deleting — ask explicitly: “Can I re-download this eSIM if I delete it from my device?” Get the answer in writing before proceeding with Fix 8.

If you are still experiencing an eSIM not working in Europe situation after all the steps above, switching to a new provider is often the fastest solution.

Still Not Working? Start Fresh With a Reliable Provider
