UAE eSIM APN settings should normally be changed only when the eSIM is installed and registered on a network but mobile data still does not work. For a NoveSIM plan that requires manual configuration, the APN is data.esim.
An APN tells the phone how to reach the mobile-data service. It does not unlock a phone, install an eSIM, add data to an expired plan or create coverage where no supported network is available.
NoveSIM UAE eSIMs are data-only and do not include a local number, conventional voice calls or SMS. APN configuration affects the travel line’s internet connection, not the services of your home SIM.
Quick answer: first select the UAE eSIM for mobile data and apply its required roaming setting. If data is still unavailable and the plan instructions call for a manual APN, enter data.esim, leave username and password blank, save it and restart the phone.

Correct UAE eSIM APN settings for NoveSIM
| Field | Value |
|---|---|
| Name | NoveSIM UAE or another recognisable label |
| APN | data.esim |
| Username | Leave blank |
| Password | Leave blank |
| Authentication | Leave at its default unless your order instructions say otherwise |
Enter the value exactly: lowercase, with a full stop and no spaces. Do not copy the APN of e&, du or another provider into a NoveSIM profile unless NoveSIM support has supplied different order-specific instructions.
Check the data line before editing the APN
A wrong data-line selection is more common than a missing APN. Open the phone’s SIM settings and confirm that the UAE eSIM is enabled and assigned to mobile data. Disable automatic data switching so the device cannot silently choose the home SIM.
Check data roaming on each line separately. A travel eSIM may require roaming to connect through its partner network, while roaming should normally remain off on the home SIM to prevent unexpected charges.
How to set the APN on iPhone
- Open Settings.
- Select Mobile Service or Cellular.
- Choose the UAE eSIM, not the home line.
- Open Mobile Data Network when that menu is available.
- Enter
data.esimin the Mobile Data APN field. - Leave username and password empty.
- Return to the previous screen to retain the setting.
- Restart the iPhone and test with Wi-Fi switched off.
Some carrier profiles hide the APN menu or fill it automatically. If the field is unavailable, do not alter another line’s settings. Capture the visible menus and contact support.
How to set the APN on Android
The exact path varies by manufacturer, but it is normally inside the selected SIM’s mobile-network settings.
- Open Settings.
- Choose Connections, Network & internet or the equivalent menu.
- Open Mobile networks and select the UAE eSIM.
- Choose Access Point Names.
- Add a new APN rather than overwriting an unrelated home-carrier profile.
- Enter a recognisable name and set the APN to
data.esim. - Leave username and password blank.
- Save the profile and select it for the UAE eSIM.
- Restart the phone, switch off Wi-Fi and test a lightweight webpage.
If Android refuses to save the profile, check for unintended spaces and make sure every required system field retains its default value.
How to tell whether the APN is the real problem
- The line shows signal but no data: the APN or data-line configuration may be responsible.
- The line shows no service: first check activation, coverage, roaming and network registration.
- Data worked and then stopped: check plan validity and remaining high-speed allowance before rebuilding settings.
- Only one app fails: the issue may be the app, permission or service availability rather than the APN.
The complete symptom-based sequence is in UAE eSIM Not Working. Dubai-specific connection behaviour is covered separately in eSIM Not Working in Dubai.
Refresh the connection safely
- Save the APN and verify that it is selected.
- Turn Airplane Mode on briefly, then turn it off.
- Allow the phone time to register on a supported network.
- Restart the device once if mobile data remains unavailable.
- Test with Wi-Fi disabled so the result is unambiguous.
Do not delete the installed eSIM unless NoveSIM support explicitly instructs you to do so. The original QR code may not support another installation, and deleting the profile does not correct an APN typo.
What not to change
Avoid changing network mode, DNS, VPN, proxy and several APN fields at the same time. Multiple simultaneous edits make it difficult to identify the actual cause and can introduce a second problem.
Do not replace the APN on the home SIM. Label the lines clearly and edit only the UAE eSIM profile. If the phone is still being prepared, follow the Dubai eSIM installation guide before troubleshooting mobile data.
Does APN choice affect 4G or 5G?
The APN enables the correct data service but does not guarantee a particular network generation. Access to 4G or 5G depends on the plan, supported local network, device bands, software, precise location and current coverage.
Leave network selection on automatic unless the plan instructions or support recommend a specific manual choice. For operator context, see the UAE network guide.

FAQ
What is the NoveSIM APN for a UAE eSIM?
When manual APN configuration is required, enter data.esim. Use lowercase letters, include the full stop and add no spaces.
Should the APN username and password be filled in?
Leave both fields blank unless the instructions for your specific order explicitly provide values.
Why can’t I see the APN menu?
Some phones or installed carrier profiles configure the APN automatically and hide manual controls. Do not edit another SIM’s profile; contact support with the device model and screenshots.
Should I delete and reinstall the UAE eSIM?
No. Do not delete it unless NoveSIM support specifically instructs you to do so. First verify the data line, roaming requirement, APN and plan status.
Final Recommendation
Use UAE eSIM APN settings only after confirming that the correct travel line is enabled, selected for data and using its required roaming setting.
For a NoveSIM plan that needs manual entry, set the APN to data.esim, leave credentials blank and test after a controlled connection refresh.
Change one setting at a time and retain the installed profile. That preserves a recoverable troubleshooting path if mobile data still does not start in the UAE.
