The NoveSIM APN for a Switzerland travel eSIM is data.esim. Most phones receive the setting automatically, so manual entry is necessary only when the eSIM shows a network connection but mobile data does not load.
An APN identifies the route used for cellular data. It does not install the eSIM, unlock the phone or replace activation, and changing it will not solve every connection problem.
NoveSIM plans are data-only and normally do not require an APN username or password.
Quick answer: Select the NoveSIM line, enter data.esim in the APN field, leave username and password blank, save the setting, then restart the data connection with Wi-Fi turned off.
Top Switzerland eSIMs
Correct NoveSIM APN Values
| Field | Value |
|---|---|
| APN | data.esim |
| Username | Leave blank |
| Password | Leave blank |
| Proxy / Port | Leave blank |
| Authentication | None or default |
Do not copy an APN belonging to Swisscom, Sunrise or Salt. A travel eSIM may use a partner network while retaining its own APN.
Enter the APN on iPhone
- Open Settings and choose Cellular or Mobile Data.
- Select the NoveSIM line rather than your primary SIM.
- Open Cellular Data Network or Mobile Data Network.
- Enter data.esim in the Cellular Data APN field.
- Leave username and password empty, then return to the previous screen to save.
- Confirm that this eSIM is selected for cellular data and that data roaming is enabled on it.
If the APN menu is hidden, the carrier profile may control it automatically. Do not reset unrelated network settings solely to expose the field.
Enter the APN on Android
- Open Settings, then Connections or Network & Internet.
- Select Mobile Networks and then Access Point Names.
- Make sure you are editing the NoveSIM profile.
- Tap Add, enter a recognisable name and set the APN to data.esim.
- Leave username, password, proxy and port blank.
- Save the profile and select it using the radio button.
- Enable data roaming for the eSIM and reconnect mobile data.
Android labels differ between Samsung, Pixel and other manufacturers. The phone must also be compatible and unlocked; installation steps are covered in how to activate a Switzerland eSIM.
Test the Setting Properly
Switch Wi-Fi off so the test cannot accidentally use the hotel or airport network. Confirm that the NoveSIM line is active and selected for data, toggle flight mode for about 20 seconds, then load a new webpage. A signal icon alone does not prove that the data session is working.
If the APN is correct but data still fails, do not repeatedly create extra APN profiles. Work through the Switzerland troubleshooting sequence, including plan status, data-line selection, roaming and automatic network selection. Do not delete the installed eSIM unless support instructs you to.
When the APN Is Not the Cause
No service usually points to network registration, coverage or an inactive line rather than the APN. A connection that works in Zurich but drops on an alpine route may be a coverage issue; consult the Swiss mobile-network guide. Plan, device, region and local conditions affect 4G and 5G availability.

FAQ
What is the NoveSIM APN in Switzerland?
The APN is data.esim. Leave the username and password fields blank.
Do I need to change the APN before arrival?
Usually not. Allow automatic configuration first and enter the APN manually only if the eSIM connects but data does not work.
Why can I not see the APN menu?
Some carrier profiles hide or manage the APN automatically. Confirm the correct data line and contact support rather than resetting unrelated settings.
Will changing the APN improve weak mountain coverage?
No. The APN can fix the data route, but it cannot strengthen a weak radio signal or add coverage where the partner network has none.
Final Recommendation
Use the NoveSIM APN data.esim only when the profile has not configured itself correctly.
Test with Wi-Fi off, the eSIM selected for data and roaming enabled on that line.
If those settings are correct and data still fails, keep the eSIM installed and follow the full troubleshooting sequence or contact NoveSIM support.
