No, an eSIM cannot use cellular data while Airplane Mode is active. Wi-Fi and Bluetooth can still work if the airline permits you to switch them back on.
After landing, turn Airplane Mode off, enable the travel eSIM and select it for mobile data. Installing the profile before the flight does not mean it can connect to a cellular network in the air.
NoveSIM travel eSIMs are data-only. We do not provide conventional calls or SMS, and the eSIM still needs cellular service to deliver mobile data.
Quick answer: Airplane Mode disables cellular service for physical SIMs and eSIMs, although permitted onboard Wi-Fi can still work. After landing, turn Airplane Mode off, enable the travel eSIM, choose it for Mobile Data and enable Data Roaming when required.
Before departure, choose the relevant country or regional plan from the NoveSIM destination list and read its activation timing. That is safer than assuming Airplane Mode can pause a validity period that has already started.
Does eSIM Work in Airplane Mode?
Not for cellular service. The eSIM remains installed on the phone, but it cannot register on a mobile network while Airplane Mode is on. Apps may continue working through onboard Wi-Fi because Wi-Fi can usually be enabled separately.
Airplane Mode does not delete, pause or damage the eSIM profile. It simply prevents cellular transmission until the mode is disabled.
Can I Install an eSIM While Airplane Mode Is On?
Installation requires an internet connection and access to the phone’s eSIM settings. On some devices, you can enable Wi-Fi after turning on Airplane Mode and complete installation, but doing this during a flight is unnecessary and can make troubleshooting harder.
Install before departure on stable private Wi-Fi whenever possible. Confirm that the profile appears in SIM settings, label it clearly and keep the activation details private. The full process is covered in how to install an eSIM.
Should Airplane Mode Be On during the Flight?
Follow the airline crew’s instructions. Airplane Mode normally remains on throughout the flight, while Wi-Fi and Bluetooth may be re-enabled when permitted. The eSIM does not create an exception to aviation requirements.
Onboard Wi-Fi is a separate service from the travel eSIM. If you connect to it, apps use the aircraft’s Wi-Fi rather than the eSIM’s data allowance.
Do I Turn Airplane Mode Off to Activate the eSIM?
Turn it off after landing when the crew permits normal cellular use. The phone must communicate with a supported mobile network for the eSIM to register and supply data.
- Disable Airplane Mode.
- Open the phone’s SIM or Cellular settings.
- Make sure the travel eSIM line is turned on.
- Select it as the Mobile Data or Cellular Data line.
- Enable Data Roaming on the travel eSIM if required.
- Leave network selection on Automatic.
- Wait several minutes, then test a normal webpage with Wi-Fi off.
Validity rules differ between plans. Some begin on installation, while others begin after the first supported network connection. Follow the order instructions rather than using Airplane Mode as a way to control validity.
What Should I Do with My Primary SIM?
You can keep the primary line enabled for calls, SMS or verification codes, but prevent it from using expensive roaming data. Turn off Data Roaming for the primary SIM and disable automatic cellular-data switching.
If you do not need the home number, switching that line off provides simpler protection. See whether to turn off the primary SIM for the trade-offs.
Why Does the eSIM Not Connect after Airplane Mode?
The phone may need time to register after the radios restart. If it remains offline, check the line selection before changing advanced settings.
- Confirm that Airplane Mode is fully off.
- Confirm that the travel eSIM is enabled and selected for data.
- Enable Data Roaming when the plan requires it.
- Keep network selection on Automatic.
- Turn Wi-Fi off temporarily to test mobile data directly.
- Restart the phone if registration does not complete.
Do not delete the installed eSIM or rescan its QR code unless Support instructs you to do so. For a broader diagnosis, follow the no-internet-abroad checklist.
Can Airplane Mode Fix a Connection Problem?
Toggling Airplane Mode on briefly and then off can force a fresh network registration. This is a troubleshooting action after landing, not a permanent operating mode for cellular data.
Wait about half a minute before turning it off, then allow the phone a few minutes to reconnect. Repeated rapid toggling is unlikely to help.

FAQ
Does eSIM work in Airplane Mode?
The installed profile remains on the phone, but cellular eSIM service is disabled. Apps can work through permitted onboard Wi-Fi.
Should I turn off Airplane Mode after landing?
Yes. Turn it off when permitted so the travel eSIM can register on a mobile network.
Will Airplane Mode delete my eSIM?
No. It disables wireless radios but does not remove the eSIM profile.
Does onboard Wi-Fi use my eSIM data?
No. Data sent through aircraft Wi-Fi does not come from the eSIM allowance.
Final Recommendation
An eSIM does not provide cellular service while Airplane Mode is active, although the profile remains safely installed.
Use permitted Wi-Fi during the flight, then turn Airplane Mode off after landing and select the travel eSIM for mobile data.
If it does not connect, verify the line, roaming and network-selection settings before restarting the phone; do not delete the eSIM.
