Croatia eSIM APN Settings: Use data.esim Correctly

NoveSIM | Last updated on: September 30, 2026 | 7 minute read

The correct NoveSIM APN for a Croatia eSIM is data.esim. Most phones receive this setting automatically, so do not edit the APN when mobile data already works.

Check the APN only after confirming that the travel eSIM is enabled, selected for mobile data and allowed to use data roaming. An APN correction can solve a missing data session, but it cannot improve weak signal, congestion or a depleted high-speed allowance.

NoveSIM travel eSIMs are data-only. They do not provide a Croatian number, conventional calls or SMS, while messaging, maps and internet-calling apps use the mobile-data connection.

Quick answer: If the Croatia eSIM has registered on a network but cannot load data, open the APN settings for that travel line and confirm the APN is data.esim. Leave username and password empty unless NoveSIM support supplies different instructions. Save the setting, select it on Android when required, restart once and test with WiFi off.

What Is the Correct Croatia eSIM APN?

Field Value
Name NoveSIM or another clear label
APN data.esim
Username Leave empty
Password Leave empty

Do not copy an APN from Hrvatski Telekom, A1 Hrvatska or Telemach Hrvatska. Those retail settings belong to their own SIM products, not to the NoveSIM travel profile.

When Should You Leave the APN Unchanged?

Leave the current setting alone when:

  • webpages and apps load through mobile data;
  • the field is populated automatically and service works;
  • the only issue is weak indoor signal;
  • data is slow only in a crowded location;
  • the plan has reached a high-speed threshold;
  • one application is slow while other services work normally.

Changing a working APN can interrupt service and make diagnosis harder. For performance problems, use the Croatia slow-data guide before editing network fields.

Checks to Make before Editing the APN

  1. Turn WiFi off.
  2. Confirm that the Croatia eSIM is switched on.
  3. Select it under Mobile Data or Cellular Data.
  4. Enable data roaming for the travel line.
  5. Disable automatic data switching to the home SIM.
  6. Keep network selection automatic.
  7. Toggle airplane mode once and wait for registration.

If data starts after these checks, no APN edit is necessary. If the phone has signal but still cannot create a data connection, inspect the APN for the travel eSIM.

Check the APN on iPhone

  1. Open Settings.
  2. Tap Cellular or Mobile Service.
  3. Select the installed Croatia eSIM.
  4. Open Cellular Data Network when that menu is available.
  5. Check the APN under the Cellular Data section.
  6. Enter the required NoveSIM value only if the field is blank or incorrect.
  7. Leave username and password empty unless instructed otherwise.
  8. Return to the previous screen to retain the setting.

Some iPhone carrier profiles hide manual APN controls. A missing menu does not automatically indicate a fault. Do not install an unrelated configuration profile to expose or replace the setting; contact NoveSIM support if the APN cannot be viewed and data remains unavailable.

Check the APN on Android

Android menu names vary by manufacturer, but the general path is:

  1. Open Settings.
  2. Select Network & internet, Connections or the equivalent network menu.
  3. Open SIMs, SIM Manager or Mobile Networks.
  4. Select the Croatia eSIM.
  5. Tap Access Point Names.
  6. Edit the relevant profile or add one only when no correct entry exists.
  7. Enter a clear name and the required APN.
  8. Save the profile and select it if Android does not select it automatically.

Do not change MCC, MNC, authentication type, APN type, bearer or protocol unless the order instructions or NoveSIM support provide exact values. Manufacturer defaults can differ, and unnecessary changes may prevent registration.

Samsung Galaxy APN Path

On many Samsung devices, open Settings → Connections → Mobile Networks → Access Point Names. Ensure that the menu applies to the Croatia eSIM rather than the home SIM.

If a correct NoveSIM entry already exists, select it instead of creating duplicates. After saving a necessary correction, return to SIM Manager and verify that the travel eSIM remains the preferred mobile-data line.

Google Pixel APN Path

On Pixel, open Settings → Network & internet → SIMs, select the Croatia eSIM and find Access Point Names in its mobile-network settings.

Android versions can rename or reposition the control. If the profile is managed automatically and the APN menu is unavailable, preserve the eSIM and contact support rather than resetting or deleting it.

Test Mobile Data after an APN Correction

  1. Confirm that the corrected APN is saved and selected.
  2. Restart the phone once.
  3. Verify that the Croatia eSIM is still selected for mobile data.
  4. Check data roaming on the travel line.
  5. Turn WiFi off.
  6. Open a lightweight webpage and refresh a map.
  7. Check the travel line’s data counter if the phone provides one.

Test two services so that a single app or website does not create a false result. If data works, stop changing settings.

APN Problem or Network Problem?

Observation More likely cause
Signal appears but no app can use mobile data Data line, roaming, APN or plan status
Data works but is slow in a crowd Congestion rather than APN
Service improves outdoors Indoor coverage rather than APN
One app fails but other websites load Application or server issue
The phone shows No Service Registration, supported network, coverage or line status
Unlimited plan slows after heavy use High-speed threshold or fair-use policy

An APN tells the network how to establish the data session. It does not improve radio coverage, force 5G or bypass a package limit.

Avoid Multiple Competing APN Profiles

Several similar entries can make it unclear which configuration Android is using. Keep one correct selected profile for the travel eSIM. Do not add variants with different punctuation or domestic operator values.

If service became worse after a manual change, compare the edited fields with the original plan instructions. Do not repeatedly reset mobile settings or create more profiles. Record the existing values and ask support which entry should remain active.

Network Selection Is a Separate Check

A correct APN does not authorise every Croatian operator. Keep automatic network selection as the baseline. If registration repeatedly fails, use the manual network selection guide and test only networks supported by the plan.

After finding a working connection, return to automatic selection before travelling to another region unless support advises otherwise.

Do Not Delete the eSIM

Deleting the profile is not an APN reset. It can remove diagnostic information and may prevent reuse of a single-installation QR code.

Keep the eSIM installed while checking the active line, roaming, network and APN. Delete it only when NoveSIM support specifically instructs you to do so.

Information to Send to Support

  • phone manufacturer, exact model and operating-system version;
  • whether the eSIM shows signal or No Service;
  • the selected mobile-data line;
  • whether roaming is enabled on the travel eSIM;
  • the APN value without exposing private order details;
  • the Croatian location and visible network name;
  • the results of a test with WiFi off.

For the broader activation sequence, review the Croatia eSIM activation guide before escalating.

FAQ

What is the APN for a NoveSIM Croatia eSIM?

The APN is data.esim. Leave username and password empty unless NoveSIM support or the specific order instructions provide different settings.

Should I change the APN if mobile data already works?

No. Leave a working automatic configuration unchanged. APN editing is appropriate when the field is blank or incorrect and mobile data cannot establish a session.

Will changing the APN improve slow data in Croatia?

Usually not when data already works. Slow service is more often related to congestion, weak coverage, background traffic or a high-speed limit.

Should I delete the eSIM to reset its APN?

No. Preserve the installed profile, correct only the necessary setting and contact support if data remains unavailable. Delete only when NoveSIM support explicitly instructs you to do so.

Final Recommendation

Check Croatia eSIM APN settings only after confirming the active data line, roaming and network registration. If mobile data already works, keep the automatic configuration unchanged.

When correction is necessary, use data.esim, leave credentials empty and avoid altering unrelated fields. Save and select the profile, restart once and test with WiFi off.

If the connection remains unavailable, preserve the installed eSIM and provide NoveSIM support with the device, line, network and APN details. A controlled correction is safer than repeated resets or duplicate profiles.
