Singapore eSIM APN settings tell the phone how to open a mobile-data session. Most eSIM profiles configure them automatically, so manual editing should be a targeted fix—not the first response to every connection problem.
For a NoveSIM Singapore eSIM, the APN is data.esim. Do not substitute the APN of a Singapore retail operator or copy settings from another travel provider.
The service is data-only. APN configuration affects internet access but does not add a local number, calls or SMS.
Quick answer: First confirm that the NoveSIM eSIM is enabled, selected for mobile data and allowed to use data roaming. If data still fails, open that eSIM’s mobile-network settings and set the APN to data.esim. Leave username and password blank unless your order instructions explicitly say otherwise, save, then restart or toggle airplane mode.

Singapore eSIM APN settings checklist
Use these NoveSIM APN values
| Field | Value |
|---|---|
| APN | data.esim |
| Username | Leave blank |
| Password | Leave blank |
| Authentication | Leave at the default unless instructed otherwise |
| APN type | Leave at the profile default unless instructed otherwise |
Change only the fields needed. Random edits to proxy, port, server, MMSC or authentication can create a second problem and make diagnosis harder.
Check the basics before editing the APN
- Confirm the eSIM profile is switched on.
- Select it as the phone’s mobile-data line.
- Enable data roaming on the travel eSIM.
- Disable automatic data switching to the home SIM.
- Turn Wi-Fi off and test a new webpage.
If the profile has not yet been enabled after arrival, follow the Singapore activation guide. APN changes cannot fix a disabled line.
Where to find APN settings on iPhone
When manual APN editing is permitted, open Settings > Cellular/Mobile Service, select the Singapore eSIM, and look for Cellular Data Network. Enter data.esim in the Cellular Data APN field.
Some carrier profiles hide this menu or manage the value automatically. If the field is unavailable, do not delete the eSIM. Restart the phone, verify the active data line and contact support with the device model and screenshots of the relevant settings.
Where to find APN settings on Android
- Open Settings and enter Mobile networks or the equivalent SIM menu.
- Select the Singapore eSIM.
- Open Access Point Names.
- Add or edit the APN and enter data.esim.
- Save the profile, then select it as the active APN.
- Toggle airplane mode or restart the phone.
Menu names differ by Samsung, Pixel and other manufacturers. Make sure you are editing the travel eSIM rather than the home carrier’s APN.
What if data.esim is already present?
If the value is correct, the fault is probably elsewhere. Check plan validity and allowance, network registration, signal, mobile-data selection and roaming. A correct APN cannot compensate for an expired plan or unsupported network.
Use the full decision path in Singapore eSIM troubleshooting. If service is merely slow rather than absent, test outdoors and at another time before changing configuration.
Why local operator APNs are not interchangeable
A travel eSIM may connect through a Singapore partner network while using its own service platform. The network name on screen therefore does not tell you which APN to enter. Using a domestic operator’s retail APN can prevent the travel profile from authenticating correctly.
The same principle applies during multi-country travel: retain the APN supplied for the eSIM unless the provider gives different instructions. For travel onward, see the Singapore and Malaysia eSIM guide.

FAQ
What is the NoveSIM APN in Singapore?
The APN is data.esim. Enter it on the NoveSIM travel profile, not on the home SIM.
Should I enter an APN username or password?
Leave both blank unless the specific order instructions explicitly provide different values.
Why can’t I edit the APN on my iPhone?
The installed carrier profile may manage or hide the field. Check the selected line and roaming, restart once and contact support rather than deleting the profile.
Will changing the APN fix weak signal?
No. APN controls data-session configuration; it does not improve radio coverage. Move location or test another supported network when signal is weak.
Final Recommendation
Edit the APN only after confirming that the Singapore eSIM is enabled, selected for data and allowed to roam.
Use exactly data.esim, keep unrelated fields at their defaults and save the APN before restarting the connection.
If the correct APN does not restore data, continue with plan, signal and network checks instead of repeatedly altering settings.
These Singapore eSIM APN settings should remain limited to the travel profile.
