Introduction
North Andaman—home to Diglipur, Mayabunder, Rangat, and wild gems like Saddle Peak and Ross & Smith—offers pristine nature but patchy connectivity. Mobile network and internet here trail mainland India: expect basic voice coverage in towns, limited 3G/4G, and frequent dead zones on beaches, jungles, and intercity roads. With the undersea cable boosting bandwidth into the archipelago, speeds in larger settlements are improving, but North Andaman remains a “download before you go” destination. This guide explains who gets signal where, what to expect from Wi‑Fi, and how to plan itineraries around connectivity.
Top Cities and Places in North Andaman for Reliable Mobile Network
Coverage varies greatly by town and terrain. In general, BSNL has the widest footprint; Airtel and Jio work in some pockets; 5G is not available at the time of writing.
Diglipur (largest town in North Andaman)
- Signal: BSNL voice/SMS is the most consistent; Airtel/Jio may show 3G/4G in town center and near Kalipur–Dudhpukki market but can drop to E/No service outside.
- Data speeds: 0.3–8 Mbps when 3G/4G bars appear; expect evening slowdowns.
- Wi‑Fi: Select mid-range hotels and a few cafés offer shared Wi‑Fi (often 2–10 Mbps, variable).
Mayabunder
- Signal: BSNL fairly reliable for calls in town; Airtel pockets of 3G/4G; Jio spotty.
- Data speeds: 0.2–5 Mbps; heavier congestion at night.
Rangat
- Signal: BSNL strongest; Airtel present around Yerrata/market area; Jio inconsistent.
- Data speeds: 0.3–6 Mbps in town; rural/jetty areas often drop to 2G or none.
Connectivity at attractions
- Ross & Smith Islands (from Aerial Bay): Often no signal on the sandbar; intermittent BSNL at Aerial Bay jetty.
- Saddle Peak National Park: No coverage on the trail and summit; signal returns near the highway.
- Kalipur, Ramnagar, Alfred Caves: Expect little to no data; occasional BSNL bars near villages.
Tourist Circuits and Connectivity Planner
Plan travel legs with offline maps and cached bookings. The Andaman Trunk Road (ATR) has long stretches with no service.
- Port Blair → Rangat → Mayabunder → Diglipur: Best for steadily improving town-to-town coverage (mostly BSNL; Airtel patches).
- Port Blair → Baratang → Rangat: Spotty to none through Jarawa Reserve/forested sections; download tickets and confirmations beforehand.
- Diglipur ↔ Aerial Bay ↔ Ross & Smith: Expect no data; carry cash for permits/boats.
- Town bases with better connectivity: Diglipur, Rangat, Mayabunder (in that order).
Activities and When You’ll Need Data
- Trekking Saddle Peak: No network during the hike. Download offline topo maps and inform your hotel of return time.
- Beaches (Kalipur, Ramnagar): Minimal connectivity; keep e-tickets/screenshots ready.
- Island hopping to Ross & Smith: Carry cash and printed IDs; don’t rely on UPI due to signal drops.
- Transport planning: Bus schedules are best checked locally; apps may not update in real time due to weak data.
Festivals and Peak Demand Periods
Island-wide events can congest networks in towns during evenings.
- Island Tourism Festival (usually Jan, centered in Port Blair): Spillover visitors increase load on networks along the ATR and in larger towns.
- Local fairs/Republic Day/Independence Day: Heavier evening congestion around markets and stadiums.
North Andaman–specific festival calendar: Information not available.
Sample Itineraries with Connectivity Expectations
3 Days: Quick North Andaman Highlights
- Day 1: Port Blair → Rangat (bus/private). Coverage: Sparse on ATR; Rangat town has workable BSNL.
- Day 2: Rangat → Mayabunder. Coverage: Town centers OK; carry offline navigation.
- Day 3: Mayabunder → Diglipur. Coverage: Improves in Diglipur town; attractions mostly offline.
5 Days: Nature + Beaches
- Base in Diglipur for 3 nights to access Ross & Smith, Kalipur. Expect full-day blackouts on beaches.
- Shift to Rangat/Mayabunder for 1–2 nights to balance sightseeing with better evening data.
1‑Week Slow Travel/Digital Balance
- Workdays in Diglipur or Rangat near main markets for more stable 3G/4G and café Wi‑Fi.
- Adventure days offline (Saddle Peak, Ross & Smith); schedule uploads at night.
Budget Tips for SIMs, Data, and Internet
- Buy a local SIM in Port Blair on arrival—airport counters are quicker and better stocked than North Andaman shops.
- Choose two different networks (e.g., BSNL + Airtel) to maximize chances of coverage.
- Typical prepaid packs: INR 199–599 for 1–1.5 GB/day, 28 days. Speeds may be far below plan caps.
- Use Wi‑Fi during off-peak hours (early morning/late night) for cloud backups.
- Cache Google Maps/YouTube/Spotify offline; keep airline/ferry tickets saved locally.
How to Reach North Andaman and Stay Connected
- Fly to Port Blair (Veer Savarkar International Airport). Buy SIMs at the airport or Aberdeen Bazaar.
- Road to North Andaman: ATR bus or private car to Rangat/Mayabunder/Diglipur (8–12 hours total to Diglipur). Expect long dead zones.
- Ferries: Limited services between Port Blair and North Andaman towns; schedules change—confirm locally.
- Permits: Indian nationals generally don’t need special permits for these towns; foreign nationals should check current Restricted Area/tribal area rules before travel.
Accommodation and Wi‑Fi in North Andaman
- Mid-range hotels/guesthouses in Diglipur, Rangat, Mayabunder may offer Wi‑Fi via local ISPs or mobile routers.
- Typical speeds: 1–10 Mbps down when available; upload often lower; outages are common.
- Power cuts occur—carry a high‑capacity power bank and a multi‑plug.
- Request rooms closer to routers or common areas for stronger signal.
Local Experiences: Food, Shopping, Culture
- Food: Simple seafood thalis, fresh fish fry, and South Indian breakfasts dominate. A few town cafés may let you use Wi‑Fi with a purchase.
- Shopping: Small markets for fruit, snacks, and basic supplies. Don’t expect electronics stores to have SIM replacements readily.
- Payments: UPI/cards work in bigger shops when network is up; carry sufficient cash for boats, stalls, and village eateries.

FAQs
Q: Which mobile network works best in North Andaman?
A: BSNL has the widest voice coverage. Airtel and Jio can offer usable 3G/4G in town centers of Diglipur, Rangat, and Mayabunder, but expect many dead zones elsewhere.
Q: Is there 5G in North Andaman?
A: No. At the time of writing, 5G is not available in the Andaman & Nicobar Islands.
Q: Can I rely on hotel Wi‑Fi for work calls?
A: Only with a backup plan. Wi‑Fi speeds of 1–10 Mbps are possible in towns, but outages and congestion are common. Schedule calls early mornings and keep mobile data as a fallback.
Q: Where should I buy a SIM?
A: Buy in Port Blair at the airport or main markets for smoother KYC and better stock. North Andaman shops may have limited SIM availability and fewer plan options.
Q: Do UPI and card payments work?
A: Often in larger town stores when network is up, but connectivity drops mean failures are common. Carry cash for boats, small eateries, and villages.
Conclusion
North Andaman is spectacular—and semi-offline. Count on BSNL for calls, carry a second SIM (Airtel or Jio) for data in towns, and plan for full-day blackouts at beaches, caves, and forests. Buy your SIM in Port Blair, cache maps and tickets, and treat Wi‑Fi as a bonus rather than a guarantee. With realistic expectations and a few backups, you can enjoy the wild side of the Andamans without losing essential connectivity when it matters.
