The Thailand eSIM APN settings for a NoveSIM travel profile use data.esim. Many phones receive the APN automatically, so edit it only when the installed eSIM has no mobile data and the basic line settings are already correct.
An APN tells the phone how to reach the mobile-data service. It does not select a package, add coverage or repair an expired allowance.
NoveSIM travel eSIMs are data-only. The APN supports internet access; it does not add a Thai number, conventional calls or SMS.
Quick answer: Select the NoveSIM line for mobile data, enable data roaming on that line when required and keep network selection automatic. If data still fails, enter data.esim as the APN, leave username and password blank unless support says otherwise, save, restart mobile data and test with Wi-Fi off.

Before changing the APN
- Confirm the eSIM appears as installed and enabled.
- Select it as the phone’s mobile-data line.
- Turn on data roaming for the travel eSIM if the instructions require it.
- Disable automatic data switching to the home line.
- Check that the plan is active and still has data and validity.

Which Thailand eSIM APN settings should you enter?
| Field | Value |
|---|---|
| APN | data.esim |
| Username | Leave blank |
| Password | Leave blank |
| Authentication | Leave at default |
Do not substitute an AIS or True–dtac consumer APN. A travel eSIM can use a Thai partner network while retaining its provider-specific APN.
How to set the APN on iPhone
- Open Settings and select Mobile Service or Cellular.
- Tap the NoveSIM travel line.
- Open Mobile Data Network when the option is available.
- Enter data.esim in the Mobile Data APN field.
- Leave username and password empty, then return to save.
- Toggle Airplane Mode on for about 20 seconds and off again.
Some carrier profiles hide manual APN editing. If the field is unavailable, do not remove the eSIM; contact support with the phone model and screenshots.
How to set the APN on Android
- Open Settings and find Connections, Network & Internet or Mobile Network.
- Select the NoveSIM line, then open Access Point Names.
- Create a new APN and give it a clear name such as NoveSIM.
- Enter data.esim in the APN field.
- Leave username and password blank, save the entry and select it.
- Toggle Airplane Mode, then test mobile data with Wi-Fi disabled.
Menu wording differs between Samsung, Google Pixel and other Android brands. The Thailand activation guide covers the wider line setup.
What if data.esim does not restore service?
Return network selection to automatic, restart the phone and test outdoors or in another location. A correct APN cannot overcome weak local reception or an unauthorised network. Consult the Thailand network guide before trying manual selection.
Record the displayed network, signal bars, error message and APN screen for support. Change one setting at a time so you know which action resolves the fault.

FAQ
What is the NoveSIM APN in Thailand?
The manual APN is data.esim. Username and password should remain blank unless NoveSIM support provides different instructions.
Do I always need to enter the APN manually?
No. Many phones configure it automatically. Enter it only when necessary after confirming the eSIM is selected for data and roaming is correctly set.
Should I use a Thai operator APN?
No. Use the APN supplied for the travel eSIM, even when the plan connects through a Thai partner network.
Should I delete and reinstall the eSIM?
No. Do not delete an installed eSIM unless NoveSIM support explicitly tells you to do so, because the QR code may not be reusable.
Final Recommendation
The correct Thailand eSIM APN settings use data.esim, after checking that the NoveSIM line is enabled, selected for data and allowed to roam when required.
Save the APN, refresh the connection and test with Wi-Fi turned off before changing anything else.
If service still fails, keep the eSIM installed and send support the device, location, visible network and settings evidence.
