The one thing worth sorting before you fly is data. Most of what makes a layover easy, from checking traffic to sharing your live location, runs on your phone.
The free airport Wi-Fi
Mumbai airport’s Wi-Fi is free. Choose #MumbaiAirportWiFi, open any web page and the login page appears. Logging in normally needs a one-time code sent to an Indian mobile number.
No Indian number? Go to an information desk or a Wi-Fi kiosk with your passport. After a quick check, they’ll give you a password. The airport explains the check is a government (Department of Telecommunications) requirement.
Roaming, eSIM or a local SIM
| Option | Good for | Keep in mind |
|---|---|---|
| Your usual roaming | Zero set-up | Check your provider’s India rates before you go; some are expensive. |
| A travel eSIM | Most layovers | Buy and install it before you fly, while you have Wi-Fi at home. Your phone must support eSIM. |
| An Indian SIM | Longer stays | Usually needs your passport, visa and a form, plus time for activation. Rarely worth it for a few hours. |
Before you land
- Download an offline map of Mumbai in your maps app.
- Save your route, your host’s details and your onward flight time somewhere you can see without data.
- Install a ride-hailing app at home, where sign-up and card checks are easier.
- Pack a power bank. A flat phone is the most common way a good day goes wrong.
In the city
Mobile coverage is good across most of Mumbai, though it can drop underground and in some older buildings. Many cafés have Wi-Fi, often with the same Indian-number login. Before you set out, you can share your live location with someone back home; our safety guide has more on that.
Quick answers
Is there free Wi-Fi at Mumbai airport?
Yes. Connect to #MumbaiAirportWiFi. Without an Indian mobile number, visit an information desk or Wi-Fi kiosk with your passport to get a password.
Should I buy an Indian SIM for a layover?
Usually not. A local SIM normally needs your passport, visa, a form and time to activate. For a few hours, roaming or a travel eSIM installed before you fly is simpler.
Will my phone work in Mumbai?
Most modern phones work on Indian networks. Check your roaming rates, or install a travel eSIM before you fly if your phone supports it.
