SIM, eSIM & the apps you’ll actually use
Staying Connected
India has some of the world’s strictest SIM registration rules for foreign visitors. Understanding this before you land — and choosing eSIM over scrambling for a local SIM at 2am — will save you real frustration on day one.
General guidance — telecom rules and app availability change. See our full disclaimer on the hub page.
Why a local SIM is more complicated than you’d expect
Indian telecom regulation (TRAI) requires passport verification, a photo, and address proof for every SIM activation — including eSIM. Even after completing registration in person, activation can take 2-24 hours. You could genuinely spend your entire first day without data if you rely on getting a local SIM at the airport.
Your two real options
International travel eSIM
The simplest path for most trips: install before you fly, connect instantly on landing, no paperwork. Most connect to Airtel or Jio’s network as a roaming partner. Slightly more expensive than a local SIM, but you avoid the registration hassle entirely — genuinely the right call for short-to-medium trips.
Local SIM (Airtel, Jio, Vi)
Cheaper long-term and gives you a real Indian number (useful for OTPs, local bookings). Requires visiting an official carrier-owned store in person with your passport, visa, and address proof. Only official stores — avoid third-party retailers, who may mishandle foreign registrations or worse.
If you go the local SIM route
What you need
- Passport + valid visa
- Local address (your hotel booking confirmation usually works)
- A passport-style photo (often taken in-store)
- No Aadhaar needed — that’s only for Indian residents; foreigners use passport-based KYC
Where to go
Official Airtel, Jio, or Vi stores — either in the city (better rates, more selection) or airport counters at Delhi, Mumbai, Bengaluru (convenient, but expect 30-60 min queues and higher prices for the convenience).
Your hotel is legally required to file a “C-Form” with the Bureau of Immigration within 24 hours of your check-in, recording your passport details against your address. Use the same address on your SIM registration as your hotel booking — consistency here avoids friction.
Scam to know: the “no paperwork” SIM
A vendor who doesn’t ask for your passport, visa, and a photo is not operating legitimately — they may be stealing your data or selling you a SIM that gets deactivated shortly after. Always insist on registering in your own name with your own documents.
Apps worth having before you land
- WhatsApp — India’s primary communication tool; hotels, drivers, and guides commonly coordinate through it, not SMS or email
- Google Maps — works fully and reliably in India, including transit directions; download offline maps for regions with patchy signal (Ladakh, remote hill areas)
- Uber and/or Ola — see Getting Around
- A UPI-capable payment app — see Money, Payments & Budgeting
WiFi reality
Hotel WiFi is generally reliable in mid-range and above properties in cities; expect it to be weaker or absent in budget guesthouses and remote areas. Cafés with WiFi are common in major cities but not universal. Don’t plan around WiFi as your primary connection — your SIM/eSIM data plan should be the reliable baseline, with WiFi as a bonus.
