India eSIM Guide: Airtel, Local SIM Rules and the Golden Triangle
India is huge, and mobile data is central to daily life there: payments, ride-hailing, train bookings and food delivery all run through apps. For visitors, the biggest practical difference between a travel eSIM and a local SIM is time. Buying an Indian SIM involves identity checks that can take a while to complete. A travel eSIM works as soon as you land.
Which networks India eSIMs use
India's main operators are Jio, Airtel and Vi (Vodafone Idea), with state-owned BSNL strong in some rural areas. Among the wholesale India plans we track:
| Plan type | Network | Where data exits |
|---|---|---|
| Roaming, single network | Airtel (5G) | Singapore |
Airtel is one of India's two largest networks, with wide coverage across cities, highways and many rural areas. Data exits in Singapore, which is relatively close and works well for maps, messaging and ride-hailing. Some Indian websites and apps may treat you as an overseas user. The routing trade-offs are explained in what a travel eSIM is.
Local SIM cards for visitors
Foreign visitors can buy Indian prepaid SIMs, but the process involves showing your passport and visa, a photo, and identity verification. Activation may not be immediate. Some states have additional rules for connections from elsewhere in India. If you need an Indian number, for example for a long stay or for apps that only accept Indian numbers, allow time for it. For shorter trips, many visitors use a travel eSIM to avoid the wait.
Coverage
| Area | What to expect |
|---|---|
| Delhi, Mumbai, Bengaluru, Chennai, Kolkata | Good 4G and 5G; congestion at peak times |
| Golden Triangle (Delhi, Agra, Jaipur) | Good in cities and along highways |
| Rajasthan (Udaipur, Jodhpur, Jaisalmer) | Good in towns; gaps in the Thar Desert |
| Goa and Kerala | Good in towns and beach areas; weaker in backwaters and hills |
| Rishikesh and the Himalayan foothills | Good in towns; patchy on treks |
| Ladakh, Spiti and high Himalaya | Limited; some areas have no coverage at all |
| Trains | Coverage along most routes; gaps in rural stretches |
Getting around
Ride-hailing apps such as Uber, Ola and Rapido operate in many Indian cities, including auto-rickshaws and motorbike taxis. They verify accounts by SMS, which can be a problem without an Indian number; set up and verify accounts at home with your home number where the app allows it.
Long-distance trains are booked through the official IRCTC system, which may require an Indian mobile number for some steps. Travel agents and some booking apps can help visitors. Delhi, Mumbai and other cities have metro systems with their own apps.
Payments and bank codes
Card payments are accepted in hotels, larger restaurants and shops, while many small businesses prefer UPI, India's mobile payment system, or cash. When you pay by card, your home bank may send a one-time passcode. Keep your home SIM active for texts with data roaming off, as described in our dual-SIM guide.
Combining India with other countries
India is often combined with Nepal, Sri Lanka or the Maldives. These countries are not covered by India plans, and regional plans that include South Asia vary. Check every country on your list. Our multi-country guide explains how.
How much data you'll need
| Trip | Suggested data |
|---|---|
| A week on the Golden Triangle | 5 GB |
| 2 weeks, Rajasthan plus Goa or Kerala | 10 GB |
| A month of travel or yoga retreats | 15 to 20 GB |
| Heavy video calls | A daily plan or a large total plan |
Hotel Wi-Fi quality varies considerably. The data guide has per-activity figures.
Before you fly: a short checklist
- Get your e-Visa or visa through the official Indian government website, not a third-party site.
- Install the eSIM at home over Wi-Fi and leave it off until you land.
- Set up ride-hailing apps with your home number before you travel.
- Download offline maps for any trekking or desert areas.
Setting up and troubleshooting
Switch the eSIM on after landing in Delhi, Mumbai or wherever you arrive. Set it as your cellular data line and enable data roaming for it. If there's no service, toggle airplane mode, then select Airtel manually. The troubleshooting guide covers the rest.
Emergency calls
India's single emergency number is 112.
