If your New Zealand eSIM is not working, first confirm that the travel line—not the home SIM—is selected for mobile data. Most arrival problems come from the wrong data line, disabled roaming, incomplete network registration or an incorrect APN.
Do not delete the installed eSIM. A QR code may be valid for one installation only, and removing the profile can turn a settings problem into a reinstallation request.
NoveSIM travel eSIMs are data-only, so the absence of a New Zealand phone number or conventional calls and SMS is normal.
Quick answer: Turn on the New Zealand eSIM, select it for mobile data, enable Data Roaming for that line, keep network selection automatic and test with Wi-Fi off. If necessary, verify that the APN is data.esim.

- Confirm that the plan is active and still has data and validity.
- Turn on the eSIM line in the phone’s SIM settings.
- Select it as the mobile-data SIM.
- Enable Data Roaming on the travel eSIM, not automatically on the home line.
- Switch off Wi-Fi and test a normal webpage.
- Restart the phone and allow several minutes for registration.
Check Network Registration
Leave automatic network selection enabled first. The plan must connect to an allowed partner, and manually forcing an unsupported network can leave the phone showing signal without usable data. If support asks for a manual test, try only the networks included in the current plan instructions, then return to automatic selection.
Coverage varies by route and terrain. If every phone nearby loses service, move to a known covered area before changing the eSIM settings. Consult the New Zealand coverage guide for rural limitations.
Verify the APN
Most phones receive the APN automatically. When manual entry is required for a NoveSIM plan, use:
| Field | Value |
|---|---|
| APN | data.esim |
| Username | Leave blank |
| Password | Leave blank |
Save the APN, select it if the phone requires that step and restart mobile data. Do not substitute Spark, One NZ or another domestic operator’s APN.
If Data Is Connected but Slow
- Check whether the phone has fallen back to a weak signal.
- Move away from thick walls or a crowded venue and test again.
- Pause cloud backup, app updates and hotspot devices.
- Run one practical test rather than repeatedly consuming data with speed tests.
- Check whether the live plan has a fair-use or high-speed allowance.
Speed depends on the partner network, location, congestion, device and plan. A 4G indicator does not guarantee a particular throughput.
Dual-SIM Problems
Disable automatic mobile-data switching if the phone keeps returning to the home SIM. On iPhone, verify the selected Cellular Data line. On Android, check the preferred SIM for mobile data. Keeping the home line available for SMS does not require letting it use roaming data.
If the profile was never installed correctly, return to the New Zealand eSIM installation guide. For plan selection, see the New Zealand eSIM guide.

FAQ
Why does my eSIM show signal but no internet?
The phone may be registered while the wrong data line, roaming setting or APN prevents a data session. Check those items in order.
What APN should I use?
For NoveSIM, use data.esim when manual APN entry is required. Leave username and password blank.
Should I select a network manually?
Start with automatic selection. Use manual selection only for a controlled test based on the current plan or support instructions.
Should I delete and reinstall the eSIM?
No. Keep the profile installed unless NoveSIM support specifically tells you to remove it.
Final Recommendation
If the New Zealand eSIM is not working, check the data line, roaming, network registration and APN in that order.
Test again in a known coverage area before treating a rural signal gap as a configuration failure.
Keep the profile installed and contact support with screenshots of the SIM, network and APN settings if the connection still fails.
