Essential Apps for India Travel: Rides, Maps, Trains and Payments

The apps that matter most in India are WhatsApp, a ride app such as Uber, Google Maps and Google Translate, plus IRCTC or an agent for trains. Set them up at home, where your home SIM receives sign-in codes easily: many Indian apps verify you by SMS, and your India eSIM is data-only. Everything below runs on your eSIM data once you land.

WhatsApp: how India communicates

In India, WhatsApp is not just for friends. Hotels confirm bookings on it, drivers send their car number and a location pin, guides share meeting points, and many shops, restaurants and tour operators take orders through it. A few habits help:

• Keep WhatsApp on your home number. It works over your eSIM data without any change, so contacts at home can still reach you.
• Save your hotel’s WhatsApp number when you book, and message it your arrival time.
• Share your live location with a driver who cannot find you — far easier than describing a lane in Old Delhi or Varanasi.
• Call home on WhatsApp or FaceTime; the eSIM has no phone number, so app calls are how you talk.

Getting around: rides, maps and trains

• Uber works in Delhi, Mumbai, Bengaluru, Chennai, Jaipur and most large cities, with cars and, in many cities, auto-rickshaws and motorbike rides. It accepts your home number, and you can usually choose cash or card. Booking an auto through an app also saves haggling over the fare.
• Ola is the other big ride-hailing app. Sign-up checks your number with a one-time code, so try registering with your home number before you travel.
• Goa is different: Uber and Ola do not operate there. Use GoaMiles, the state-backed taxi app, or a prepaid taxi counter at the airports.
• Google Maps gives driving, walking and metro directions in cities such as Delhi, Mumbai, Bengaluru and Chennai, plus reviews and opening hours. Download offline maps for every region on your route.
• IRCTC is the official booking system of Indian Railways, on the web and in its Rail Connect app. Foreign visitors can register with a passport and an international mobile number (the code goes to your home SIM), and some trains have a Foreign Tourist Quota of seats you can book in advance with an international card. Popular routes, such as Delhi to Agra, can sell out, so book early or ask your hotel or a travel agent to book for you.
• Live train status apps show where your train is and how late it is running — helpful on long routes, where delays are common.

Paying in India: cash, cards and UPI

India runs on UPI, the national instant-payment system: you will see QR codes at tea stalls, markets, taxis and temples. Standard UPI apps need an Indian bank account and an Indian mobile number, so most visitors rely on:

• Cards at hotels, restaurants, malls and larger shops. Tell your bank you are traveling.
• Cash for small vendors, auto-rickshaws, tips and many smaller guesthouses. ATMs are easy to find in cities; carry a reserve when heading to rural areas.
• UPI for visitors: NPCI, which runs UPI, offers a prepaid wallet for international visitors called UPI One World, activated with your passport and home number. Providers and eligibility change, so check the current options before you go and do not make it your only way to pay.

One common confusion: Google Pay in India is a UPI app tied to Indian bank accounts, not the same tap-to-pay wallet you may use at home.

Food, tickets and apps that want an Indian number

Zomato and Swiggy are India’s main food-delivery apps, and both are useful for browsing menus and reviews. Signing in relies on a one-time code sent to your phone number, and an Indian number may be required; if yours is not accepted, ask the hotel front desk to order for you — staff do this all the time. The same applies to some event, cinema and local service apps, and to many public Wi-Fi logins.

For sights, the Taj Mahal and other monuments run by the Archaeological Survey of India sell entry tickets online, which can save time at the gate. Buy through the official site rather than resellers, keep the ticket saved on your phone and carry the passport you booked with.

Translation, weather and other useful extras

• Google Translate covers Hindi and many regional languages, including Bengali, Tamil, Telugu, Marathi, Gujarati, Kannada, Malayalam and Punjabi. Camera mode reads signs and menus; conversation mode helps with drivers and market stalls. English is widely used in hotels and tourism, so you will mostly need it in smaller towns and markets. Download offline languages where available.
• A weather app matters in monsoon season — roughly June to September across most of India, while Chennai and the southeast coast get their heaviest rain from about October to December. Storms can delay trains and flights.
• Emergency number: 112 is India’s single emergency number. Your eSIM cannot make calls, but your home SIM can, and phones can usually reach emergency numbers over any available network.
• Power: carry a power bank (in your hand luggage, never in checked bags) and a plug adapter — Indian sockets are mostly types C, D and M, and power cuts still happen in some areas.

Most of these apps are light on data; see our India data guide to size your plan, read the complete India eSIM guide for setup, and pick a plan from the India eSIM plans list.
