Papua New Guinea is hundreds of languages, cloud-forest highlands, smoking volcanoes and coral seas, held together by small aircraft rather than roads. It is also one of the dearest places in the Pacific to roam, so install the eSIM before you fly and you are online when you land at Port Moresby.


Almost every visitor arrives at Port Moresby's international airport, mostly from Brisbane, Cairns, Singapore or Manila, and a good many walk straight across to the domestic terminal for an onward flight. A few cross the land border from Indonesian Papua near Vanimo. Either way you will want to confirm your pickup, check that the connection is still running and tell someone you have landed.

In Port Moresby, Lae, Mount Hagen, Goroka, Madang, Kokopo and the other provincial centres you can expect workable 4G, and it generally reaches the airports and the main hotels.
Outside the towns, assume very little. Most of the country is mountain, swamp and forest with no roads, and coverage is a scatter of towers around villages and mission stations rather than a network. On the Kokoda Track, along the Sepik, on the smaller islands and in most of the Highlands away from the highway, there are long stretches with nothing at all. Plan as though you will be offline, and enjoy it when you are not.

Papua New Guinea is a hard and costly country to build a network in, and roaming prices reflect it. For most home plans it falls in the most expensive band, and it is commonly excluded from "worldwide" passes and from Asia-Pacific bundles — including, often, plans from neighbouring Australia. Check the price list before a single email downloads.
Local SIMs are sold in Port Moresby and must be registered with identification, which means a shop, a queue and a form.
A travel eSIM takes the question away: a fixed price, paid before you leave, on a local network.
This is not a country for improvising. Book airport transfers and accommodation ahead, go with a local guide or operator outside the main hotels, and do not walk around Port Moresby, Lae or Mount Hagen after dark. Read your government's current travel advice before you go.
Share your itinerary with someone at home, and send it while you still have signal.
There is no road from Port Moresby to the Highlands, the islands or the north coast, so almost every journey is a flight — and flights are regularly delayed or cancelled by weather and by everything else. Do not book an international departure for the same day as a domestic connection.
Keep tickets, booking references and your hotel's phone number saved offline, and carry some kina in cash for the day the plan changes.
Possibly, and seldom cheaply. Most operators bill Papua New Guinea at their highest roaming rate and leave it out of daily passes and regional bundles, Australian plans often included. Check your own price list first — or use a travel eSIM and know the cost before you board.
Hardly at all. There may be a bar or two near the trailheads at Owers' Corner and Kokoda and at the odd village or ridge along the way, but for most of the walk there is nothing. Trekking operators carry satellite phones or radios for that reason; tell family to expect silence until you walk out.
Expect 4G in the towns and slower or no data elsewhere. Whether your plan uses 5G is shown on each plan's card.
No — a Papua New Guinea plan covers Papua New Guinea. Australia has its own plans, and if your route continues through several countries in the region, a regional plan is the simpler choice.
You do not need one. Local SIM cards have to be registered with identification before they work, which for a visitor means finding a shop and showing a passport. An eSIM installed at home is ready when you land, and leaves your first hour free for the transfer.
Yes. The currency is the kina. Larger hotels, supermarkets and airlines take cards, but markets, village guesthouses, local guides and boat owners are paid in cash, and cash machines outside the main towns are scarce and not always working. Withdraw in Port Moresby or a provincial capital before heading out.
One eSIM can cover Papua New Guinea and the countries around it — no need to buy a plan at every border:
