Madagascar eSIM for Antananarivo, the RN7, the lemurs, and Nosy Be

Madagascar is a country of long roads, taxi-brousses that leave when full, and national parks where the guide confirms by message the night before, and the arrivals hall at Ivato is the place to have a phone that already works. The best eSIM for Madagascar is the one added at home, on Wi-Fi, so the hotel's driver is found and tomorrow's departure on the RN7 is confirmed before the visa desk.

Below: how a Madagascar plan works, how to set it up before you fly, what to expect in Antananarivo, on the road south, and on the islands, and which plan fits when Mauritius or Réunion is on the same trip.

African itineraries change, and most travel eSIMs make you start over every time they do. KnowRoaming doesn't. You add the KnowRoaming eSIM, called KR.One, to your phone once, then add a plan per trip: one country when you're staying put, the Africa plan when the route crosses borders, and whatever comes next after that. Nothing to scan again, nothing to delete when you get home.

The plan's days start when you turn it on and connect in Madagascar, not at checkout. Buy it weeks ahead, add it at home, and a delayed flight costs you nothing. The full rule is in what plan validity means and when it starts.

Choose a fixed plan for a set amount of data at the lowest overall price, or an unlimited plan when you'd rather not count. Unlimited plans give you 5 GB a day at full speed, then a slower speed until the allowance resets the next day. If a fixed plan runs low, top up in the app and the extra data lands on the same eSIM.

See it in two minutes: Meet KR.One, iPhone setup with KR.One, or Samsung setup with KR.One.

Do this at home on Wi-Fi. It takes about a minute.

Before you leave

1. Get the KnowRoaming app (available on iOS and Android) and choose your Madagascar plan.
2. Tap Add. First time on this phone? The app adds KR.One and your Madagascar plan together. Already have KR.One? Only the plan is added, with nothing to scan.
3. Leave data roaming off on the KnowRoaming line until you land, and turn it off on your home line too so it doesn't run up charges in the background. Steps are in turning off roaming on your home line.

When you land

1. Turn the plan on in the app, then turn data roaming on for the KnowRoaming line. That setting lives in your phone, so the app can't flip it for you.
2. Give the phone a minute to find the network. If nothing happens, turn airplane mode on for 30 seconds and off again.

Prefer a QR code? The checkout page and your confirmation email both carry one; scan it from your phone's settings. Every tap, by device, is in adding your eSIM on iPhone, adding your eSIM on Android, and adding your eSIM on Samsung, or watch the iPhone QR walkthrough or the Samsung QR walkthrough. Still no signal after landing? Work through the no-signal checklist.

Ivato airport is about 45 minutes to an hour from central Antananarivo in traffic, and most visitors are met by the hotel or a pre-booked driver; a visa on arrival is available for most passports, paid in cash. The ariary is the currency, cards work in the capital's better hotels and a few restaurants, and cash covers nearly everything else; the ATMs in the cities take foreign cards, the ones in the towns often don't.

Getting around the country is by taxi-brousse, hired car with a driver, or the domestic airline, whose schedules change; the distances are long and the roads slow, and two hundred kilometers is a day. Antananarivo's Rova palace, the Analakely market, and the lake are the first day.

The RN7 from Antananarivo to Tuléar is the classic route, a week or more through Antsirabe's rickshaws, Ranomafana's rainforest and its lemurs, Fianarantsoa, the Anja reserve's ring-tails, and the canyons of Isalo before the coast at Ifaty. Yas's 4G holds in the towns along the road; the parks and the stretches between towns drop out on every network.

Antsirabe's hot springs and its rickshaws, the Zafimaniry woodcarving villages off the road near Ambositra, and the Anja reserve's lemurs an hour south of Fianarantsoa are the stops worth a day each; the tea and wine estates around Fianarantsoa are the surprise. Book each night's guesthouse from the previous town by message, since the next one may not have signal.

Andasibe, three hours east of the capital, is the indri's forest and the easiest park to reach; the Avenue of the Baobabs at Morondava, the Tsingy de Bemaraha's limestone needles, and the Kirindy forest are the west, a flight or two long days of road. All are offline once you leave the last town; download maps, save the guide's number, and expect the phone to be a camera.

Nosy Be, a flight north, is the beach island, with the resorts, the diving, and the boat trips to Nosy Komba and Nosy Iranja; Île Sainte-Marie on the east coast is the whales from July to September. Nosy Be's main towns have 4G; the smaller islands and the boats do not. Book the boats in Hell-Ville while you have data.

Madagascar is on the Africa plan, 31 countries on one plan that also covers Mauritius, Réunion, Mayotte, and Seychelles, the usual island add-ons by air, with the phone switching networks by itself when you land; it is also on the Global plan. A Madagascar-only plan stops at the coast. Read do I need a new plan for every country? for the detail.

Your plan connects to Yas on 4G LTE. There is no 5G on this plan. Coverage is strong in Antananarivo, Antsirabe, Fianarantsoa, Tuléar, Diego Suarez, and on Nosy Be, and holds in the towns along the main roads. Your phone picks the network automatically once the plan is on; there is nothing to choose by hand.

In the parks, on the western roads, on the smaller islands, and between the towns, expect long stretches with no signal on any network. Power cuts are common outside the capital, so a power bank keeps the phone useful. Save what you need in town.

Most phones sold since 2019 support eSIM, including iPhone XS and later and most Android flagships from the same window. Check yours before you add a plan; it takes a few seconds. On iPhone, go to Settings, General, About and look for an EID or Available SIM. On Android, go to Settings, Network & Internet, SIMs and look for an option to add an eSIM. On Samsung, dial *#06# and look for an EID.

Your phone also needs to be carrier-unlocked. If you're not sure, carrier-locked vs unlocked: how to tell shows you where to look.

Adding a Madagascar plan doesn't touch your regular SIM. Calls and texts on your usual number keep working exactly as before. The new plan handles data while you're there, and most phones run both at once without you doing anything else. Bank codes and two-factor texts still arrive on your home number, as long as that line stays switched on.

For Africa the alternatives are a home-carrier roaming rate that is often not offered at all, a local SIM in each country with registration paperwork at each border, or lodge Wi-Fi that works in the bar and nowhere else. A Madagascar plan added at home beats all three: one price agreed before you fly, live the second you land, and one plan across every border on the route.
