An eSIM that is not working in Iceland is usually failing at one of four layers: the profile is missing, the phone has not registered on a network, the registered line has no data path, or the connection is merely slow.
Start with what the status bar and SIM settings actually show. Randomly changing the APN or deleting the profile can turn a recoverable settings problem into a reinstallation problem.
NoveSIM is data-only, so an absent Icelandic phone number is expected and is not evidence of failure.
Quick answer: Find the matching symptom below, make one reversible change at a time, test with Wi-Fi off, and keep the installed eSIM unless NoveSIM Support explicitly tells you to remove it.

| Symptom | Failure layer | Start here |
|---|---|---|
| The Iceland/NoveSIM line is absent from SIM settings | Installation | Reconnect to dependable Wi-Fi and check whether the profile was ever added; do not assume the QR code can be rescanned repeatedly. |
| The line exists but shows No Service, SOS or no network | Registration or coverage | Enable the line, leave network selection on Automatic and move to an open location before testing. |
| Bars or 4G/5G appear but nothing loads | Data-line, roaming, allowance or APN | Select the travel line for Mobile Data and enable Data Roaming on that line. |
| Pages load but calls, video or hotspot are poor | Performance or application | Test a simple webpage on the phone itself and pause background traffic. |
No Service: Recover Network Registration
- Confirm that the installed Iceland eSIM is switched on.
- Set Network Selection to Automatic.
- Turn Airplane Mode on for about 30 seconds, turn it off and allow several minutes for registration.
- Restart the phone once if the state does not change.
- Check whether another phone on a different service also lacks signal at the same location; terrain can create a genuine coverage gap.
If automatic selection repeatedly fails in a covered area, use the controlled manual-network test. A plan may offer partner access without guaranteeing every displayed operator. For route context, consult the Iceland eSIM coverage guide.
Signal but No Internet: Repair the Data Path
- Switch Wi-Fi off so the test really uses mobile data.
- Select the Iceland eSIM as the phone’s Mobile Data or Preferred Data SIM.
- Enable Data Roaming on the travel line; keep roaming off on the home line unless you intentionally use it.
- Disable automatic cellular-data switching, which can hide which line is being tested.
- Check the plan’s remaining allowance and validity.
- If the line is registered but the APN is empty, enter data.esim. Leave username and password blank.
The focused NoveSIM APN reference explains why an APN can fix data but cannot fix No Service.
Connected but Slow: Measure Before Resetting
Move outdoors or away from thick walls, stop cloud backup and disconnect hotspot clients. Test an ordinary webpage before a speed test: repeated speed tests consume allowance and do not reveal whether a specific app is the problem. If 5G is unstable, automatic or 4G mode can be more usable. Record the time, location, network name and whether the problem affects the phone itself or only a tethered device.
When to Hand the Case to Support
Contact NoveSIM Support with the order number, exact model, current location, status-bar state and screenshots of the travel line, data-line and roaming settings. Do not include the QR code. This evidence is more useful than repeating restarts.
Do not delete the installed eSIM. Some activation codes are intended for one installation. Removal should happen only on explicit support instruction.

FAQ
Why does the eSIM show a network but no internet?
The usual checks are data-line assignment, Data Roaming, allowance/validity and then the NoveSIM APN. Registration has already succeeded, so troubleshoot the data path.
Will resetting all network settings help?
It may, but it also removes saved Wi-Fi and Bluetooth settings. Use the narrower checks first and ask support before a broad reset.
Can poor coverage be fixed in settings?
No setting can create a radio signal in a dead zone. Move to a broader or more populated area when safe and use offline route information.
Final Recommendation
Diagnose the visible layer instead of cycling through every setting.
Use reversible checks, test the phone without Wi-Fi and preserve the eSIM profile.
If the evidence does not identify the fault, send support the precise symptom, location and settings state so the next action is targeted.
