Free WiFi at Delhi Airport can help you check flight information, open hotel reservations, contact your driver or send a message after arriving in India. It is available throughout the passenger terminals, but connecting may require mobile-number verification.
Airport WiFi is useful while you remain inside Indira Gandhi International Airport. However, it will not keep you connected after leaving the terminal, so tourists who need Google Maps, transport apps and WhatsApp throughout their trip should also prepare a mobile data option.
For many international visitors, the easiest setup is to install an India eSIM before departure and keep airport WiFi as a temporary or backup connection.
Quick answer: select GMR FREE WIFI, enter your mobile number, complete the OTP verification and follow the login instructions. If verification is difficult or you need internet outside the terminal, activate a pre-installed India eSIM.

The service is useful for:
- Checking flight information.

How to Connect to Delhi Airport WiFi
- Open the WiFi settings on your phone, tablet or laptop.
- Select GMR FREE WIFI.
- Wait for the airport login page to open.
- Enter your mobile number.
- Request the verification code.
- Enter the OTP you receive.

Do You Need an Indian Phone Number?
The standard connection process uses mobile-number verification. Travelers who can receive the required OTP should be able to complete the login process using the instructions displayed by the airport portal.
International visitors may occasionally experience difficulties receiving an OTP because of roaming restrictions, delayed SMS delivery or limitations connected with their home operator.
Keeping your primary SIM active for incoming SMS may help. Before travelling, confirm whether your home operator allows you to receive SMS messages in India and whether any roaming settings are required.
What If You Do Not Receive the OTP?
If the verification code does not arrive, try the following:
- Check that your primary SIM is enabled.
- Confirm that the correct country code and phone number were entered.
- Wait a few minutes before requesting another code.
- Turn Airplane Mode on for 30 seconds and then turn it off.
- Reconnect to the WiFi network.
- Ask airport assistance staff whether another verification method is available.
- Use your travel eSIM for mobile data if it is already installed.
Do not repeatedly request codes within a few seconds because this may temporarily delay or block additional requests.
