eSIM Not Working or SOS Only: Solutions
Does your eSIM show “SOS,” “No Service,” or no internet connection? “SOS only” means the iPhone is not connected to its normal cellular network. It does not necessarily mean the eSIM profile is defective: the selected line, roaming setting, coverage or network registration may be the cause.
What does “SOS only” mean?
On iPhone, “SOS” or “SOS only” means the device is not connected to its usual cellular network. Emergency calls may still be possible through another carrier in some regions, but VoyageSIM data is not connected yet.
| What you see | Likely cause | First action |
|---|---|---|
| SOS or No Service | The eSIM has not registered on a network | Check the line, roaming and Airplane Mode |
| Signal bars, no internet | Wrong data line, APN or inactive plan | Select VoyageSIM for mobile data |
| QR code already used | The profile may already be installed | Do not delete the eSIM; check cellular lines |
| Intermittent connection | Local coverage or network selection | Return to automatic network selection |
Troubleshoot in this order
- Confirm the destination and plan validity. The country must be included and the usage period must have started.
- Turn on the VoyageSIM line. On iPhone, open Settings > Cellular, tap the VoyageSIM line and turn on this line.
- Select VoyageSIM for mobile data. Only one line can supply cellular data at a time.
- Enable roaming on the VoyageSIM eSIM when required by the plan instructions. Keep roaming off on your Canadian line to reduce the risk of charges.
- Turn on Airplane Mode for at least 15 seconds, then turn it off to force a new network search.
- Check the date and time. Open Settings > General > Date & Time and enable Set Automatically.
- Restart the phone. Then wait a few minutes with Wi-Fi off while testing cellular data.
- Keep network selection on Automatic. Select a network manually only when the plan instructions or VoyageSIM support tells you to.
- Do not guess the APN. Enter an APN only when it appears in the plan email or is provided by support.
On Samsung or Android
Open Settings > Connections or Network & Internet > SIM Manager. Turn on the VoyageSIM eSIM, select it for mobile data and follow the plan’s roaming instructions. Menu names vary by brand and Android version.
Do not delete the eSIM
Deleting the profile is not a normal troubleshooting step. Many QR codes are single-use, and reinstalling may require provider assistance. Read Why you should not delete an eSIM first.
When to contact VoyageSIM
If the problem remains, send your order number, destination, phone model, exact error message and a screenshot of the cellular settings. Never post your QR code publicly.
