An eSIM at Delhi Airport is most useful when it is installed before departure and ready to provide mobile data after landing. This avoids relying on a SIM counter or completing registration while you are tired and still arranging the transfer.
Delhi Airport also provides free Wi-Fi. Its official instructions distinguish between travellers with an active Indian mobile number and international visitors who may need a passport-based coupon from an information desk or self-service kiosk.
NoveSIM travel eSIMs are data-only. We do not provide an Indian number or conventional calls and SMS, but maps, ride-hailing and online messaging work through data.
Quick answer: Install the India eSIM on Wi-Fi before flying. After landing at Delhi Airport, select it for Mobile Data, enable Data Roaming on that line and test it with Wi-Fi off. Keep the airport’s official Wi-Fi procedure as backup.

Why prepare the eSIM before Delhi Airport?
Installation requires a reliable connection and may involve displaying a QR code on another screen. Completing this before departure gives you time to confirm that the profile appears in the phone and is labelled correctly.
First check the exact device with the India eSIM compatibility guide, then compare the current India eSIM plans.
Activate mobile data after landing
- Turn on the installed India eSIM line.
- Select it as the phone’s Mobile Data line.
- Enable Data Roaming on the travel eSIM.
- Keep roaming disabled on the primary SIM.
- Leave network selection on Automatic initially.
- Turn Wi-Fi off and load a normal webpage.
The India activation guide gives the complete arrival settings. Hotspot, 5G and partner-network availability depend on the selected plan, device and local coverage.
Use Delhi Airport Wi-Fi as backup
The airport’s published network is GMR FREE WIFI. Travellers with an active Indian number can receive an OTP. Those without one are instructed to visit an information desk or Wi-Fi kiosk, use a passport and obtain the login coupon details.
Follow current airport signage because network names and login flows can change. The dedicated Delhi Airport Wi-Fi guide explains the connection and portal checks.
eSIM or local SIM at Delhi Airport?
An eSIM is convenient when you need data immediately and do not require an Indian number. A registered local SIM may make more sense for a long stay or number-dependent services, but identity checks and activation take time. Compare the process in the Delhi Airport SIM-card guide.
Prepare for the airport transfer
Save the accommodation address, booking reference and pickup point before leaving the terminal. Delhi Airport is large, so confirm the terminal and exact meeting area with the driver. Download an offline map as a fallback.
If the eSIM has no data
Check the active data line and roaming first. If manual APN entry is required for NoveSIM, use data.esim. Toggle Airplane Mode and restart the phone after confirming the settings.
Do not delete the installed profile. Continue with the India eSIM troubleshooting guide or contact support.
