Can You Stay Connected in Andaman? A Local's Guide to Internet & SIMs
Let's be honest, internet in the Andamans isn't like the mainland. As locals, here's our real advice on SIM cards, Wi-Fi, and what to expect when you visit.

''' So you've just landed at our little Veer Savarkar Airport in Port Blair, switched your phone off airplane mode, and... nothing. The signal bar is empty. You start to panic a little. How will you post that first coconut-water selfie? How will you let your family know you've arrived safely?
Take a deep breath. We see this all the time. Getting online in the Andaman Islands isn't as straightforward as it is back on the mainland, but it's a thousand times better than it used to be. A few years ago, we got a fancy undersea fiber optic cable connecting us to the rest of India, which was a huge deal for us locals. But things are still a bit different here. Think of it as a gentle nudge to unplug and enjoy the view.
Here’s the real scoop on what to expect from the internet, Wi-Fi, and mobile networks in the Andamans.
The Reality of Island Internet
Let’s set your expectations straight. While we do have 4G now, it’s not the lightning-fast, stream-from-anywhere connection you might be used to. The network is concentrated in populated areas like Port Blair, Swaraj Dweep (Havelock), and Shaheed Dweep (Neil Island). Venture off the main roads, and you might find your signal drops to 3G, 2G, or vanishes completely.
What does this mean for you? Basics like WhatsApp messages, checking emails, and posting on social media (with a bit of patience) are usually fine. Making a clear Voice over IP (VoIP) call can be a bit hit-or-miss. And trying to have a long video call or stream a high-definition movie? You might as well be trying to catch a fish with your bare hands. It’s possible, but it’ll take a lot of luck and patience.
Our advice is to embrace the occasional disconnection. It's part of the island charm! For everything else, a little planning goes a long way.
Which SIM Card Works Best?
This is the golden question. Your best bet for staying connected is to have the right local SIM card. If you can, try to get one from a major provider on the mainland before you fly to Port Blair, as it can save you some hassle.
If you need to get one here, here’s our breakdown of the main players:
- Airtel: In our experience, Airtel currently offers the most reliable and fastest 4G speeds, especially in the main tourist hubs of Port Blair and Havelock. If you’re sticking to the popular spots, this is probably your best choice.
- BSNL: For a long time, the government-run BSNL was the only real option. It still has the widest coverage across the entire archipelago. If you plan on exploring more remote areas like Diglipur or Little Andaman, a BSNL SIM is a must-have. The speeds might not always be the fastest, but you’re more likely to have a signal where other networks don’t.
- Vodafone Idea (Vi): Vi’s network is still growing here. Its coverage can be quite inconsistent and is mostly limited to parts of Port Blair. We usually steer visiting friends away from relying on it as their primary connection.
To buy a SIM card in Port Blair, you'll need to visit an official store and provide a copy of your ID (like an Aadhaar card or passport) and a passport-sized photograph. Activation can sometimes take a few hours, so it's best to get it sorted on your first day.
What About Hotel & Café Wi-Fi?
Almost every hotel, resort, and cafe in tourist areas will advertise "Free Wi-Fi." But, and this is a big but, the quality varies wildly. I once spent a solid hour trying to upload a single photo at a nice resort in Havelock because the Wi-Fi was so slow—it’s just the way things are!
Most establishments use the very same cellular networks (like Airtel or BSNL) to power their Wi-Fi routers. So, if your phone has no signal, the Wi-Fi is likely to be down, too. It’s often good enough for sending a quick message or checking a flight status, but don't count on it for downloading large files or attending an important video meeting for work.
Think of hotel Wi-Fi as a potential bonus, not a guarantee. Your own mobile data is almost always the more dependable option.
FAQs
Q: Can I use my international SIM card on roaming in Andaman? A: You can try, but we strongly advise against it. Most international roaming plans don't work well here, if at all. Even if you do get a signal, the data rates will be incredibly expensive and the speeds will be painfully slow. A local Indian SIM is a much more practical and affordable choice.
Q: Is there 5G in the Andaman Islands? A: No, not yet. We’re still working on perfecting our 4G network! For now, you can expect 4G in the main towns and 3G or even 2G in more rural or remote island areas. It’s best to keep your expectations in check.
Q: I need to do some work. Are there any internet cafes? A: Internet cafes have become very rare here, just like on the mainland. You might find one or two old-school places tucked away in Port Blair's Aberdeen Bazaar, but they are not common. Don't rely on finding one.
Q: Should I download things before I arrive? A: Yes, a hundred times yes! This is our biggest tip. Before you leave for the airport, download offline Google Maps for the Andaman Islands—it’s a lifesaver. Also, download any movies, TV shows, music playlists, and e-books you might want. You will be very happy you did, especially during ferry rides or on a quiet evening. '''
