Introduction
Port Blair, the gateway to India’s Andaman Islands, blends emerald bays with colonial history—and a connectivity story that has improved dramatically in recent years. Thanks to an undersea cable and expanded 4G, staying online in Port Blair is easier than before, though island-hopping still brings pockets of weak signal. This guide covers mobile networks, internet options, SIM and eSIM logistics, realistic speeds, costs, and on‑the‑ground tips—plus essential city highlights for your itinerary.
Mobile Networks Overview
Three providers matter most in Port Blair:
- Jio (4G/LTE): Generally the fastest in central Port Blair with stable VoLTE. Coverage extends to main tourist areas; speeds vary at busy times.
- Airtel (4G/LTE): Reliable city coverage and decent performance; often a strong second choice and sometimes better indoors.
- BSNL (3G/4G in pockets): Wide legacy presence; performance can be inconsistent. Useful as a backup where others dip.
Vodafone Idea has little to no usable service in most tourist‑visited parts of the Andamans.
Internet and Wi‑Fi in Port Blair
- Hotel Wi‑Fi: Common in mid‑range and upscale stays; speeds range from 5–30 Mbps in town. Outages can occur; ask for a recent speed test.
- Cafés/Restaurants: Select cafés in central areas provide guest Wi‑Fi. Expect basic browsing speeds; streaming may buffer at peak hours.
- Fiber Broadband: Available in parts of Port Blair via BSNL and private operators; not universal. Some properties run fiber to shared routers.
- Public Wi‑Fi: Limited and often slow. Don’t rely on it for work.
SIM Cards and eSIM for Travelers
- Where to buy: Airport kiosks at Veer Savarkar International Airport and authorized stores around Aberdeen Bazaar.
- Documents:
- Indian nationals: Aadhaar or other government ID; local address details.
- Foreign travelers: Passport and valid visa; passport photo (often captured digitally).
- Activation time: 15 minutes to a few hours; occasionally up to 24 hours.
- eSIM: Jio and Airtel support eSIM on compatible devices. Availability for prepaid lines varies by store; process requires OTP/SMS, so a physical SIM is often simpler on arrival.
- Domestic roaming: Mainland India SIMs generally work in Port Blair under standard domestic roaming with no extra fee, but speeds can be subject to fair usage policies.
Coverage by Area
- Strong (generally good 4G): Aberdeen Bazaar, Phoenix Bay, Junglighat, Haddo, Dairy Farm, Corbyn’s Cove road.
- Moderate (variable indoors/peaks): Chidiya Tapu, Wandoor, Chatham, outskirts and hilly stretches.
- Weak or intermittent: Mount Harriet National Park trails, North Bay, Netaji Subhash Chandra Bose (Ross) Island beyond jetty areas, sections of Baratang and forested corridors.
- On ferries/boats: Patchy signal between islands; expect dead zones off the coast.
Speeds, 4G/5G and Undersea Cable
- Typical 4G speeds (Port Blair town): 5–25 Mbps down, 2–10 Mbps up; off‑peak can spike higher, peak evenings may dip below 5 Mbps.
- Latency: Often 50–120 ms to mainland India endpoints.
- 5G status: As of the latest public updates, 5G availability in Port Blair remains limited or unavailable. Plan for 4G/LTE and VoLTE for calls.
- Undersea cable: The Chennai–Andaman (CANI) cable boosted backhaul significantly, improving consistency in Port Blair compared to pre‑2020 conditions.
Workation and Remote Work
- Viability: Feasible in central Port Blair if you choose accommodation with fiber or strong 4G and a backup power solution.
- What to ask properties: Wired vs. Wi‑Fi backhaul, router location in your room block, power backup (generator/inverter), and a current speed test at evening peak.
- Gear: Dual‑SIM phone or travel hotspot, extra data pack, offline app access, and a power bank.
- Video calls: Schedule during off‑peak hours; keep cameras off when bandwidth dips.
Estimated Connectivity Costs
- Prepaid SIM (one‑time): INR 150–250 (often included when you buy a plan).
- Tourist data packs (28 days): INR 299–699 for 1–2 GB/day; INR 719–999 for 2–3 GB/day and bundled voice/SMS.
- Data top‑ups: INR 98–301 for extra high‑speed data.
- Hotel Wi‑Fi: Usually included; some budget stays may charge INR 100–300/day.
- Local broadband (monthly): Varies widely; not typically practical for short stays.
Must‑Visit Places in Port Blair
While your focus may be connectivity, don’t miss these highlights. Signal notes included for planning.
- Cellular Jail (National Memorial): Moving evening light‑and‑sound show; 4G generally available near the complex.
- Corbyn’s Cove Beach: Easy city beach escape; signal is usually fine on the access road, moderate on the sand.
- Netaji Subhash Chandra Bose Island (Ross Island): Ruins and peacocks; connectivity thins away from the jetty.
- Chidiya Tapu: Sunset favourite; expect variable coverage—download maps beforehand.
- Wandoor & Mahatma Gandhi Marine National Park (Jolly Buoy access): Scenic and serene; low or no signal at piers and on boats.
Local Culture, Food and Shopping
- Food: Fresh seafood, South Indian tiffin, North Indian staples, and Bengali influences. Try fish thalis and coconut‑forward curries.
- Shopping: Aberdeen Bazaar has souvenirs, island spices, and everyday essentials. You’ll also find SIM stores and phone accessories here.
- Culture: Museums tell the islands’ layered history. Respect restricted zones protecting indigenous communities; tours do not enter these areas.
Nearby Getaways and Island Connectivity
- Swaraj Dweep (Havelock Island): Best beaches (Radhanagar, Kalapathar). Jio/Airtel 4G in village areas; weaker at remote beaches.
- Shaheed Dweep (Neil Island): Compact and calm. Usable 4G near main market; spotty along coastal viewpoints.
- Baratang (Limestone Caves): Forest corridors and permits; expect long stretches with no signal.
Tip: Cache maps, tickets, and hotel directions offline before ferries or early morning transfers.
How to Reach Port Blair
- By air: Direct flights from Chennai, Kolkata, Bengaluru, and seasonal connections from Delhi and other cities to Veer Savarkar International Airport (IXZ).
- By sea: Government ships operate from Chennai, Kolkata, and Visakhapatnam on limited schedules (multi‑day voyages). Connectivity at sea is minimal.
- On arrival: Airport is the easiest place to purchase a SIM; carry ID and a local contact address (hotel booking works).
Accommodation Options
- Budget (INR 1,200–2,500): Guesthouses near Aberdeen Bazaar; basic rooms, variable Wi‑Fi.
- Mid‑range (INR 3,000–6,000): City hotels and boutique stays; better Wi‑Fi and backup power more likely.
- Premium (INR 7,000–15,000+): Sea‑view hotels and resorts; strongest chance of fiber and dedicated routers.
Always verify connectivity specifics with the property before booking, especially if you plan to work online.
