An eSIM not working in France usually needs a settings check: first confirm that the plan is active, the eSIM line is switched on and the phone is using it for mobile data. Most arrival problems come from an incomplete activation, disabled data roaming, the wrong data line or an incorrect APN—not from a damaged eSIM.
Work through the checks in order while you have reliable WiFi. Test after each change so that you know which setting restored the connection, and do not delete the installed eSIM unless NoveSIM Support specifically asks you to remove it.
NoveSIM travel eSIMs are data-only. They do not provide a French telephone number or conventional calls and SMS, but WhatsApp, FaceTime and other internet services work once mobile data is connected.
Quick answer: Keep the France eSIM installed. Turn it on, select it for Mobile Data, enable Data Roaming on that line and disable automatic data switching. Test with Wi-Fi off, confirm plan validity and allowance, then verify data.esim only if manual APN entry is required.

The symbol and message on the phone determine the right next step. “No SIM” suggests the installed profile is disabled or unavailable. “No service” points to network registration. Signal bars without working internet usually indicate a data-line, roaming or APN setting.
| What you see | Check first |
|---|---|
| The eSIM line is missing | SIM settings and installation status |
| No service or SOS only | Arrival, coverage and network selection |
| Signal bars but no internet | Mobile-data line, roaming and APN |
| Data works but is slow | Location, congestion, allowance and network mode |
| Internet stops after some use | Plan validity and remaining high-speed data |
Check that the France plan is ready to use
Open the order information and verify the destination, validity period and activation instructions for the purchased plan. Some plans begin when they first register on a supported network; others may have different activation conditions. Follow the instructions supplied with that specific eSIM rather than assuming that every plan starts in the same way.
If the eSIM has not yet been installed, use the France eSIM installation guide. If it is already visible in the phone settings, do not scan the QR code repeatedly and do not remove the profile.
Use the eSIM as the mobile-data line
Dual-SIM phones can show an active travel eSIM while continuing to send data through the home SIM. Give the two lines clear labels such as “Home” and “France”, then choose the France eSIM for cellular data.
- Open the phone’s SIM or mobile-network settings.
- Confirm that the NoveSIM eSIM line is switched on.
- Select that line for Mobile Data or Cellular Data.
- Disable automatic cellular-data switching while testing.
- Keep the home line active only if you still need calls or SMS and understand its roaming charges.
For a clean explanation of the two-line setup, see the France eSIM versus SIM comparison.
Enable data roaming on the travel eSIM
A travel eSIM may connect through a partner network, so data roaming normally needs to be enabled on the NoveSIM line. This setting does not mean the home SIM must also roam.
- Open the settings for the installed NoveSIM line.
- Turn Data Roaming on for that line.
- Confirm again that the same line is selected for mobile data.
- Turn Airplane Mode on for about 20 seconds, then turn it off.
- Wait several minutes for the phone to register and test a new webpage.
Set the APN to data.esim
If the phone has signal but cannot load data, inspect the access point for the NoveSIM line. The required NoveSIM APN is data.esim. Do not copy an Orange, SFR, Bouygues Telecom or Free Mobile APN into a travel eSIM merely because that network name appears on the screen.
| Field | Value |
|---|---|
| APN | data.esim |
| Username | Leave blank |
| Password | Leave blank |
Save the change, select the APN if Android presents a list, and restart mobile data. The complete menu paths are in the France eSIM APN guide.
Let the phone choose a supported network
Leave network selection on Automatic initially. The partner network depends on the purchased plan and may not be the operator you expected from a general France coverage comparison.
If automatic registration continues to fail, open the order details to confirm the authorised networks before testing them manually. Select only a network supported by the plan, allow up to a few minutes for registration, and return to Automatic after the test. The France mobile-network guide explains why coverage can change between cities, motorways, mountains and indoor locations.
What if there is service but the connection is slow?
Move outdoors or closer to a window before changing more settings. Dense stone buildings, underground Métro platforms, tunnels, Alpine valleys and crowded venues can all weaken a usable connection. A phone may also remain attached to a congested cell after a train journey.
- Toggle Airplane Mode to request a fresh network registration.
- Check whether the plan’s high-speed allowance has been used.
- Pause cloud backups, photo uploads and operating-system updates.
- Test with 4G/LTE if an unstable 5G connection repeatedly drops.
- Compare performance in a second location before concluding that the eSIM has failed.
If consumption is higher than expected, use the France travel data calculator to identify the likely source.
When should you contact NoveSIM Support?
Contact Support when the plan is valid and the steps above do not restore service. Send useful evidence rather than deleting the eSIM: the order number, phone model, current city, exact error, visible network name and screenshots of the eSIM, data-roaming and APN screens. Hide unrelated personal information.
If you can, also note whether the phone shows signal bars and whether the failure began immediately after arrival or after data had already worked. That distinction helps separate activation and registration problems from allowance or local-coverage issues.

FAQ
Why does my France eSIM show signal but no internet?
The usual causes are the wrong mobile-data line, disabled data roaming or an incorrect APN. Select the NoveSIM line for data, enable roaming on that line and verify that the APN is data.esim.
Should I delete and reinstall an eSIM that is not working?
No. Do not delete the installed eSIM unless NoveSIM Support instructs you to do so. A QR code may not be reusable, and most connection problems can be resolved without removing the profile.
Why does my eSIM stop working outside a French city?
Coverage can weaken in tunnels, mountain valleys, rural areas and some buildings. Test outdoors, allow automatic network selection and download essential routes before travelling through areas where reception may be intermittent.
Can my normal SIM stay active while I troubleshoot?
Yes, but make sure the NoveSIM line is selected for mobile data and disable automatic data switching. Your home operator may still charge for calls, SMS or roaming activity on the other line.
Final Recommendation
For an eSIM not working in France, troubleshoot in a fixed order: plan status, enabled line, data selection, roaming, APN and network registration. Test after every change instead of changing several settings at once.
Keep the APN as data.esim, start with automatic network selection and never delete the installed profile unless Support requests it.
Once the connection returns, download essential tickets and maps for the next journey so that a tunnel, rural road or crowded station does not leave you without the information you need.
