The NoveSIM APN for a Serbia eSIM is data.esim when manual entry is required. Most profiles configure the APN automatically, so do not replace a working value merely because a generic guide shows a manual field.
An APN defines the path used for mobile data. It does not choose the radio network, activate an expired plan or create coverage in a signal gap.
NoveSIM Serbia plans are data-only. We do not provide conventional calls, SMS or a Serbian number.
Quick answer: First confirm the Serbia eSIM is selected for data and Data Roaming is on. If the supplied instructions require a manual APN, enter data.esim, leave username and password blank, save it and select it for the travel line.

Edit it only when mobile data fails after correct line selection and the NoveSIM instructions call for manual entry. If data already works, leave the automatic configuration unchanged.
APN on iPhone
Open Settings → Mobile Service/Cellular → Serbia eSIM → Mobile Data Network when the menu is available. Enter data.esim in the mobile-data APN field and leave credentials blank.
Apple may hide APN editing when carrier configuration controls it. Do not reset network settings solely to reveal the field. Use the iPhone guide for line selection.
APN on Pixel and Samsung
On Pixel, open Network & internet → SIMs → Serbia eSIM → Access Point Names. On Samsung, use Connections → Mobile networks → Access Point Names. Create or edit the NoveSIM entry, save it and select it.
Menus vary by version. See the Android guide for device-specific navigation.
Do Not Use a Local Operator APN
mts, Yettel and A1 publish settings for their own local products. Those values do not replace the NoveSIM APN. A travel eSIM can roam on a Serbian network while retaining its provider’s data configuration.
The distinction is explained in the Serbia mobile-networks guide.
Test after Saving
- Select the saved data.esim profile.
- Confirm Data Roaming is enabled on the travel line.
- Toggle Airplane Mode for 30 seconds.
- Turn WiFi off and load a lightweight page.
- Restart the phone if data still does not begin.
If registration itself fails, APN editing may not be the correct fix. Check network selection separately.

FAQ
What is the NoveSIM APN in Serbia?
Use data.esim when manual NoveSIM APN entry is required.
What username and password should I enter?
Leave both blank unless support provides different plan-specific instructions.
Why can I not see the APN menu?
The phone or carrier configuration may control it automatically. Confirm line settings and contact support instead of forcing a reset.
Should I delete the eSIM to reset the APN?
No. Do not delete the eSIM profile. Correct or reselect the APN while keeping the installed profile on the phone.
Final Recommendation
Use data.esim for Serbia eSIM APN settings only when manual NoveSIM configuration is required.
Keep credentials blank, save and select the entry, then test with WiFi off.
Do not mix APN and network-selection changes or delete the installed eSIM during troubleshooting.
