India SIM eSIM and UPI Payments

Why this needs a little planning

India runs on mobile phones. Cab apps, food delivery, train bookings, restaurant bills and street stalls increasingly rely on a working data connection and digital payments. As a visitor, you can get both working, but it takes a bit more planning than in many countries, because SIM registration has stricter identity checks and UPI was built for people with Indian bank accounts.

Getting mobile data

Option 1: eSIM bought before travel

International eSIM sellers offer India data plans. You install the eSIM at home and switch it on when you land.

Check:

• Your phone supports eSIM and is unlocked
• Whether the plan includes an Indian number. Many are data only, which means you cannot receive local SMS. That matters for some apps that send OTPs to an Indian number
• Coverage outside big cities if you are travelling to the hills or rural areas

Option 2: Local SIM

The main operators are Jio, Airtel and Vi. Foreign visitors can get a prepaid SIM, but the process involves documents:

• Passport
• Indian visa or e-Visa approval
• A passport-sized photo (some stores take it on the spot)
• A local address, usually your hotel

Airtel and others have had counters at major airports at various times, and operator stores are in every city. Activation after verification can take a few hours, so do not count on it working instantly. Some visitors buy the SIM on arrival day and use hotel Wi-Fi until it is live.

A local number is useful for cab apps, food delivery and receiving calls from drivers or hotels.

Option 3: International roaming

Simple and immediate. Usually expensive. Check your provider's daily rate.

Paying for things

Cash

You need some cash in India. Autos, small shops, tips, temple donations and many street vendors prefer it. ATMs are everywhere in cities, and most accept foreign cards. Some charge a fee on top of your bank's fee. Carry smaller notes. Change for a 500 rupee note can be hard at a small stall.

Cards

Visa and Mastercard are accepted at hotels, malls, chain restaurants, many mid-range restaurants, and ticket counters at major monuments. Contactless works in many places. Amex and some other cards are accepted less widely.

Tell your bank before you travel. Some issuers block Indian transactions by default.

UPI

UPI is India's real-time payment system, and it is everywhere. Small tea stalls and fruit sellers have a QR code on a stand. Residents pay by scanning with a banking app.

For foreign visitors, it is less simple. Standard UPI apps need an Indian bank account and Indian mobile number. Options that have been made available to visitors include prepaid UPI wallets for inbound travellers, which can be loaded with foreign currency and used to pay merchant QR codes, and support for some NRI and international numbers through specific banks. Availability, issuers and limits change, so check current options before you rely on one.

Practical approach for a short trip: cash plus a card for most things, and do not plan your budget around UPI unless you have set it up and tested it.

Safety basics

• Only scan QR codes displayed by the merchant at the counter, not ones sent by message
• You never need to enter your PIN to receive money. Anyone asking you to "scan to receive" is attempting fraud
• Do not share OTP codes with anyone, including people claiming to be from your bank, hotel or a cab company
• At the airport, ignore people who approach offering to "help" with a SIM, money exchange or taxi. Use counters and official stores
• Avoid banking on open public Wi-Fi

Getting around while you set up

The airport is where this matters first. If your SIM is not live yet, you cannot book an app cab. A pre-booked transfer solves that: the driver is waiting with your name, tracks your flight, and your Booking ID is on the voucher. Options: Delhi Airport T3 to Delhi NCR, Delhi Airport to Gurugram, and on the way out, Delhi NCR to Delhi Airport. The payment is done when you book, so there is nothing to sort out in cash at the curb.

The same applies to day trips: book online ahead and the fare is settled. A same-day Delhi to Agra round trip or a full day Delhi sightseeing car avoids haggling over the fare. Bring cash for monument tickets, snacks and tips during the day.

For the city itself, the metro accepts cash for tokens at stations. See Delhi Metro getting around.

Phone setup checklist

1. Check eSIM support and that the phone is unlocked
2. Buy an eSIM before you go, or plan to get a local SIM with passport and visa
3. Download offline maps for your first city
4. Install the cab app you plan to use and log in before you leave home
5. Save your hotel address and phone number in your notes
6. Save each Booking ID and the support contact from your vouchers
7. Turn off data roaming on your home SIM once local data works

Costs you should expect to pay in cash

• Tips for drivers and guides
• Autos and cycle rickshaws
• Small food stalls and chai
• Shoe minders at some temples and donations
• Small parking or entry fees at lesser-known sites

FAQ

Can I get a SIM at Delhi airport?

There have usually been operator counters or kiosks at major airports, but availability changes. Operator stores in the city are a reliable fallback.

How long does a foreign SIM take to activate?

It varies. Plan for a few hours rather than minutes.

Can I use Google Pay or PhonePe with a foreign number?

Generally, standard UPI apps need an Indian bank account. Look at visitor-specific options instead.

Are cards safe to use?

Yes, at established businesses. Watch the card when paying, and use contactless where possible.

Should I exchange money before arriving?

A small amount helps. ATMs at the airport are fine for most visitors.
