Palau Rock Islands Southern Lagoon from the air: eSIM and mobile coverage guide for Koror, Babeldaob, Peleliu and the offshore dive sites

Palau eSIM Guide

Koror • Rock Islands • Blue Corner • Peleliu

Which network you actually get, what it costs, and where it stops

Which Network a Palau eSIM Actually Uses

Palau has two mobile operators: PNCC, the state-owned incumbent, and Palau Mobile Communications (PMCI). Those are not interchangeable for a traveller, because a roaming eSIM only works on the network its supplier has an agreement with.

Palau Mobile Communications (PMCI)

Our plans

Every Palau plan in our catalogue is declared against this one network, at 4G. If your phone ever asks you to choose a network by hand in Palau, this is the one to pick.

Verified against our own coverage data on 9 September 2026.

PNCC (Palau National Communications Corporation)

Not our plans

The other operator in the country, and a normal choice if you buy a local prepaid SIM in person. It is not the network our eSIM plans register on, so we do not make coverage claims for it here.

What we will not pretend to know: nobody publishes a tower-by-tower coverage map for Palau, and we have not measured one. What is defensible is that mobile service in Palau is built around the populated core — Koror and the developed part of Babeldaob — and that the Rock Islands, the offshore dive sites and the outer islands are not places anyone should count on a signal. This page says "expect nothing" there rather than inventing a percentage.

Quick Palau Facts for Travellers

Capital

Ngerulmud, on Babeldaob — the least populous national capital in the world. Koror is the largest town and where visitors actually stay.

Population

About 17,700 (2025 estimate; the 2021 census counted 16,766). Around two thirds of everyone lives in Koror State.

Currency

The US dollar. There is no separate Palauan currency, so no exchange step for anyone arriving with dollars.

Power

US-style type A and B sockets at 120 V. A US charger works as it does at home; a European or UK one needs an adapter.

Language & dialling

Palauan and English, both official. English is widely used with visitors. International dialling code +680.

Time zone

UTC+9, the same clock as Japan and Korea, and no daylight saving at any point in the year.

On emergency numbers: plenty of travel pages state one for Palau. We could not confirm a single national emergency number against any authoritative source, so we are not going to print one and hope. Before you travel, get the numbers that will actually matter from the people responsible for you: your accommodation, your dive operator, and — for anything involving decompression — your dive insurer's emergency line. Save them offline in your phone, not in a browser tab.

Things About Entering Palau That Surprise People

You will sign the Palau Pledge, and it goes in your passport

In 2017 Palau became the first country in the world to write an environmental promise into its entry process. The Palau Pledge is stamped into passports, and every visitor signs it in front of the immigration officer on arrival. It is addressed to the children of Palau and commits you to tread lightly and take nothing that is not given. It is not a formality anyone skips, and it is a fair signal of how the country expects visitors to behave once they are here.

There is an environmental fee, and a separate Rock Islands permit

Palau charges a Pristine Paradise Environmental Fee, normally collected as part of the airfare rather than at a desk on arrival. We could not verify the current amount against an official source while writing this, so we are not going to quote you a number — check it with your airline when you book, because a stale figure on a travel blog is worse than none. Separately, visiting the Rock Islands and Jellyfish Lake needs a permit bought locally; Wikipedia's Jellyfish Lake article puts the combined Rock Islands / Jellyfish Lake pass at 100 US dollars for five days, which is the right order of magnitude, but confirm it with Koror State or your operator rather than with us.

Jellyfish Lake is not a guaranteed stop

This is the single most common disappointment in Palau, and it is worth knowing before you build a trip around it. The golden jellyfish population in Ongeim'l Tketau collapsed during the 2015-16 El Niño: the Coral Reef Research Foundation, which monitors the lake, records the last medusa being seen in May 2016, the jellies then being virtually absent until late 2018 as the lake cooled, and the population estimated in the millions again by 2019. Access has tracked those numbers ever since. So treat the lake as something to confirm when you book, not as a fixture. If it is open, go; if it is not, the Rock Islands are still there.

The Compact with the US is not a phone plan

Palau has been in a Compact of Free Association with the United States since 1994. It covers defence and security, US funding commitments, and reciprocal rights for most Palauan citizens to live and work in the US and for most US citizens to live and work in Palau — US passport holders enter without a visa. What it does not do is make Palau part of anyone's domestic mobile network. Palau is a sovereign country with its own dialling code, +680, not a US territory like Guam, Puerto Rico or the US Virgin Islands, and those territories are the ones that sit inside US carriers' domestic footprints. Look up "Palau" by name on your own carrier's international page before you assume anything.

Why an eSIM Beats a Local SIM Card in Palau

The practical problem in Palau

Palau is a country of roughly 17,000 people. There is no arrivals hall packed with SIM kiosks and no 24-hour phone shop. Buying a local prepaid SIM means finding an operator's office or an authorised dealer during business hours, in person, with your passport.

That is the whole case for an eSIM here. You install it at home on your own wifi and it is live when you land, whatever day of the week you arrive.

What a local SIM in Palau actually involves

Office hours, not airport kiosks

Prepaid SIMs are sold from operator offices and authorised dealers in Koror during business hours. Flights into Palau frequently land late in the evening, so an arrival outside office hours means no local SIM until the next working day.

An eSIM installed before you fly does not care what time you land.

It costs you trip time, not just money

Palau is an expensive destination to reach and dive packages are priced by the day. A morning spent getting a SIM sorted is a morning of a short trip gone.

Check current dive package prices with your operator; they are the biggest line item of the trip.

Roaming here is international, not domestic

Palau's Compact of Free Association with the United States covers entry, defence and the right of Palauans to live and work in the US. It does not make Palau part of any US carrier's domestic footprint the way Guam or Puerto Rico are. For a US phone, Palau is international roaming, and for a European phone it sits well outside EU/EEA roam-like-at-home.

Check your own operator's rate for "Palau" by name before you fly, not the generic international zone.

Hotel wifi is a shared, cable-limited resource

All of Palau's international bandwidth arrives by submarine cable, shared across the whole country. TeleGeography's Submarine Cable Map lists two landing at Ngeremlengui: SEA-US, in service since 2017, and Echo, the newer of the pair. Hotel wifi quality varies a lot and is at its worst in the evening when everyone is back from the water.

Mobile data is a genuinely useful second route, not a duplicate of the hotel connection.

What an eSIM actually solves

Before you leave home

  • Install while packing - ready when you land
  • No office visit - No operator counter, no passport, no business hours
  • Works at weekends - no business-hours problem
  • Instant activation - connected at the airport

When you arrive in Palau

  • Coordinate dives at once - call the operators the moment you land
  • Sort permits and tours - Rock Islands passes, boat times, pickups
  • Upload photos daily - from Koror, in the evening
  • A second route to the internet - When the hotel wifi is having an evening

The honest summary: an eSIM does not give you coverage where there are no towers, and in Palau there are no towers over most of the water you came to dive. What it does give you is data from the moment you land, in Koror and the populated parts of the country, without a shop visit and without international roaming rates. For a trip this short and this expensive, that is the whole point.

What you will actually use it for in Palau

Coordinating dives: confirming pickups with operators and liveaboards
Sharing photos: uploading the day's shots from Koror
Being reachable: your dive insurer's emergency line, and people at home
Getting around Koror: dive shops, restaurants, shops
Checking the weather: planning tomorrow's boat day
Booking: Rock Islands permits and tours

How to Set Up an eSIM for Palau

Pro Tip: Install Before Your Flight

Install the profile at home, on wifi you trust, before you leave. Then it is live the moment you land at Roman Tmetuchl International Airport — which matters here, because the alternative is finding an operator office in Koror during business hours.

Installation in 3 steps

1

Purchase Your Plan

Pick a size from 1 GB to 20 GB and a validity from 3 to 30 days. The QR code arrives by email straight away — no shop visit and no local paperwork.

2

Scan QR Code

Settings → Cellular/Mobile → Add eSIM → Scan QR code. Works on iPhone (XS+), Samsung, Google Pixel, and most modern phones. Install while on home WiFi.

3

Activate Upon Arrival

Turn on data roaming for the eSIM line. It registers on Palau Mobile Communications — that is the network to pick if your phone ever asks you to choose one by hand.

Common eSIM Issues & Quick Fixes

Stuck on "Activating..." on iPhone

A general iOS eSIM behaviour, not specific to Palau

Fix: Turn OFF VPN before installing eSIM. Toggle Airplane mode ON (wait 30 sec) then OFF. Wait 2-3 minutes. If still stuck after 10 min, restart phone.

"No Service" after landing

Almost always the data-roaming toggle

Fix: Settings → Cellular → your eSIM line → turn ON "Data Roaming". A travel eSIM is always roaming, so this is not optional. Wait 30-60 seconds for it to register on Palau Mobile Communications.

No signal once you leave the populated areas

Not a fault, and not something an eSIM can fix

What to do: mobile service in Palau follows the population, and almost nobody lives on the Rock Islands or at the offshore dive sites. Download offline maps and anything you need to read before you get on a boat, and treat the water as unconnected.

Activation takes several minutes on a new Samsung

A general Android eSIM behaviour, not something specific to Palau

Fix: give it 5-10 minutes with data roaming left ON before you decide anything is wrong. If there is still no connection after 15 minutes, restart the phone, then contact us.

Still stuck? Contact our support team — most activation problems are a data-roaming toggle or a network-selection setting, and take a couple of minutes to sort out.

Real Cost Comparison: What Travelers Actually Pay

Palau is one of the most expensive wholesale data markets in the world, so honest numbers matter more here than usual. Carrier day-pass rates change often — check yours by name before you fly. Our own prices are live in the plans section above, and they are not cheap either; they are simply far below roaming.

US carrier day pass

Charged per day, every day

The major US carriers all sell international travel as a flat daily fee, and Palau is on the international side of that line, not the domestic side. Multiply the daily fee by every day of the trip — including the days you spend underwater and never touch your phone.

Per day

European or Australian roaming

Top international zone

EU roam-like-at-home applies only inside the EEA. Palau is normally in the most expensive zone on the tariff, where a bundle-free megabyte can cost more than a gigabyte at home.

Check by name

Local prepaid SIM in Koror

Ask the operator

A reasonable option for a long stay, and it gives you a Palauan number. The costs it adds are a trip to an office in business hours with your passport, and a phone slot given over to it.

In person
BEST VALUE

eSIMfly Palau eSIM

See live prices above

One local family in five sizes, from 1 GB up to 20 GB, with 3, 7, 15 and 30-day validity. Prices move with the wholesale market, so we show them live rather than printing a number that goes stale.

Week-Long Cost

How to do this comparison properly: open your carrier's international page, search for "Palau" specifically, and multiply the daily fee by the number of days you are away. Then compare that to the live plan prices above. On a week-long trip the gap is normally large — but the number that matters is yours, on your tariff, not one we made up.

How Much Data Do You Actually Need in Palau?

These are budgets built from measured per-app consumption, not from anonymous trip reports. They are deliberately conservative for Palau, because a large part of a Palau trip is spent on a boat or underwater with the phone in a dry bag, consuming nothing at all. Our largest Palau plan is 20 GB, so if a budget below comes out higher than that, the honest answer is to plan around hotel wifi for the heavy uploads.

Light — 3 GB is enough for a week

Messaging your dive shop, maps around Koror, email, a few photos to family. This is most divers, because the diving itself uses nothing.

  • • Messaging apps, text and voice notes: ~50 MB/day
  • • Maps and navigation around Koror: ~50 MB/day
  • • Email and web: ~100 MB/day
  • • A handful of photos shared: ~150 MB/day
  • Roughly 350 MB/day, so about 2.5 GB across a week

Moderate — 5 to 10 GB for a week

Add a daily photo upload from the day's diving and a video call home, and you land here.

  • • 40-80 photos uploaded per day, at 5-10 MB each: ~600 MB/day
  • • One short video clip a day: ~300 MB/day
  • • A video call home: ~300-500 MB/hour
  • • Social feeds and browsing: ~200 MB/day
  • Roughly 1.2-1.8 GB/day, so 8-12 GB across a week

Heavy — you will outgrow any Palau plan

Underwater photographers and video creators uploading full-resolution footage every evening.

  • • Raw or high-bitrate footage backup: 2 GB+ per dive day
  • • Long-form video upload: ~1.5 GB each
  • • Full-resolution stills backup: ~800 MB/day
  • Well past 20 GB in a week, which is more than our largest Palau plan

Be realistic about this one. There is no unlimited Palau plan, and Palau is an expensive market per gigabyte. Back the big files up to a laptop or drive, upload over your accommodation's wifi overnight, and keep the eSIM for the things that have to work anywhere: maps, messaging, bookings and being reachable.

Palau-specific notes

  • Download before you get on the boat. Maps, dive-site notes, reading, music. Once you are out among the islands, assume nothing loads.
  • The diving days are your cheapest days. A phone in a dry bag for eight hours uses almost nothing, which is why week-long Palau budgets come out lower than they do for a city trip.
  • Photos are the whole budget. A modern phone photo is 3-8 MB and a short 4K clip is hundreds of megabytes. Everything else on this page is noise by comparison.
  • Every megabyte in Palau crosses a submarine cable. Uploads compete with the whole country for the same link, and evenings are the busiest time. Overnight uploads genuinely work better.
  • Validity matters as much as size here. The same 3 GB is sold with 3, 7 or 30-day validity at slightly different prices. Buy the validity that covers your trip, not the cheapest line.

Common eSIM Problems in Palau, and What They Actually Mean

Three of the four things that go wrong in Palau are not faults at all. Knowing which is which saves you a support ticket and a bad afternoon.

"No Service" after landing

What is happening:

The profile installed fine but the line never registers on a network at Roman Tmetuchl International.

Fix, in order:

  1. 1. Settings → Cellular → your eSIM line
  2. 2. Turn ON "Data Roaming". Every travel eSIM roams by definition, so leaving this off guarantees no service.
  3. 3. Toggle Airplane mode on for 30 seconds, then off
  4. 4. If it still will not register, set network selection to manual and choose Palau Mobile Communications
⚠️ No signal out at the dive sites or the Rock Islands

This is not a fault:

Mobile networks are built where people live, and the Rock Islands Southern Lagoon is uninhabited protected area. Nobody — not us, not a local SIM, not your home carrier — sells coverage over open water an hour offshore. Download offline maps in Koror before you sail, tell people at home you will be out of contact for the day, and let the dive boat's radio do the job it exists for.

📶 It works, but everything feels slow

Why, and what helps:

Palau's entire international bandwidth arrives over submarine cable and is shared by the whole country. Historically the country was on satellite, and connectivity was famously slow and expensive; the cable changed that, but Palau is still a very small market at the end of a very long link. We are not going to quote you a megabits-per-second figure we have not measured. What is true and useful: messaging, maps, email and booking sites work; large uploads are slow; and the network is busiest in the evening when everyone is back from the water. Push big uploads to overnight.

🔄 Nothing works on the liveaboard

Expected:

Liveaboards spend the week at remote sites with no terrestrial coverage at all. If a boat offers internet it is satellite, which is its own service with its own price. Your eSIM is useful at each end of the trip — in Koror before you board and after you step off — and that is a reasonable thing to buy it for. Do not buy 20 GB for a week you will spend at sea.

The short version

  • ✓ Install the profile before you fly, on home wifi
  • ✓ Data roaming must be ON, always
  • ✓ Manual network choice, if needed: Palau Mobile Communications
  • ✓ Use it for maps, messaging, bookings and being reachable
  • ✓ Expect nothing offshore, on the Rock Islands or on a liveaboard
  • ✓ Download maps and reading before every boat day
  • ✓ Save big uploads for overnight, or for the wifi where you sleep
  • ✓ Size the plan to the days you are actually on land

Network Coverage Across Palau

Palau is roughly 17,000 people spread across an archipelago, and the mobile network reflects that: it follows the population, and the population is concentrated in Koror and the developed strip of Babeldaob. Our Palau plans register on Palau Mobile Communications at 4G. We do not have a tower-by-tower map, and we are not going to draw one from imagination, so this section is written as two lists: places where coverage is a reasonable expectation, and places where it is not.

Reasonable to expect coverage

  • Koror — the main town, and where you will spend your land time
  • Roman Tmetuchl International Airport and the road in
  • Airai and the developed part of Babeldaob
  • Hotels, dive shops and restaurants in and around Koror
  • The Koror–Babeldaob bridge and the main compact road

Plan for no coverage

  • The Rock Islands Southern Lagoon — uninhabited protected area
  • Offshore dive sites: Blue Corner, German Channel, Ulong Channel
  • Open water generally, including liveaboard anchorages
  • Peleliu and Angaur — small, distant, and not something we can promise
  • The outer islands: Kayangel, Sonsorol, Hatohobei

On Peleliu and the outer islands specifically: plenty of pages will tell you Peleliu has "weak 4G". We have no source for that and no measurement of our own, so we will not print it. Treat a day trip to Peleliu, or any night on an outer island, as a day without data, and be pleasantly surprised if it is not. If being reachable there matters — a work obligation, a medical reason, someone at home who needs you — talk to your tour operator about their own communications before you commit to the trip.

Data Recommendations by Type of Trip

How much data each kind of Palau trip actually uses

These are planning estimates, not reports from named travellers, and they all assume that video calls, photo backup and streaming go over wifi. That assumption matters more in Palau than almost anywhere else, because data here is expensive and the whole country shares a small amount of submarine-cable capacity. Each profile ends with the plan size we would buy.

Dive week out of Koror

Day boats to the outer reefs, nights back in town

7 daysBudget 3-5 GB

Where you will be:

Koror base, day trips to Blue Corner, German Channel, Ulong

Data usage breakdown

Days 1-2

Arrival, dive shop check-in, gear setup, briefings

~400 MB (maps, messaging, bookings)
Days 3-6

Two to four dives a day; phone is off or dry-bagged for most of it

~400 MB/day back in Koror in the evening
Day 7

Surface interval day, check-in, departure

~400 MB

Planning notes

  • Expect no mobile data at the dive sites themselves. Boats coordinate by VHF radio, not by phone.
  • Your data day happens in Koror in the evening, not on the water — that is where the plan gets used.
  • Download offline maps and any dive briefing PDFs before you leave town.
  • Photo and video backup is a hotel-wifi job in Palau, not a mobile-data job.

Planning notes

  • RAW files and 4K clips will eat any plan sold for Palau in a day or two. Upload compressed proxies on mobile data and leave the originals for wifi.
  • On a liveaboard you should assume no cellular coverage at all for the whole leg.
  • Palau sits on submarine cable capacity shared by a very small population — upstream speed is the constraint, not your plan size.
  • Turn off automatic camera-roll backup on mobile data before you fly. On this destination that one setting matters more than the plan you buy.

Planning notes

  • Rock Islands Southern Lagoon is a protected UNESCO site made up of uninhabited limestone islands. Do not plan on coverage out there.
  • Buy permits and book tours while you still have signal in Koror.
  • Jellyfish Lake access has been suspended in the past when jellyfish numbers dropped. Check its current status with your operator before you count on it.
  • Screenshot your permit and booking confirmations so you are not hunting for signal at the dock.

Planning notes

  • One phone as a hotspot is far cheaper than a plan per person, and works fine in Koror.
  • Children streaming video is what actually drains a family plan. Download shows before you fly.
  • Video calls home are the second-biggest line item — put them on hotel wifi where you can.
  • Palau runs on UTC+9 with no daylight saving, so work out the call window home before you leave.

Planning notes

  • Do not plan a month of video calls on a Palau mobile plan. Book accommodation with a connection you have verified, and keep the eSIM for when it fails.
  • Palau has historically had slow and expensive internet; a second submarine cable has improved things, but this is still a very small market.
  • Power cuts and weather affect everything on a small island. A charged phone with its own data is a real backup.
  • For a full month, a locally registered SIM may work out cheaper per GB — the trade is the paperwork and the office hours.

Planning notes

  • This is the one Palau trip where a small plan is not a compromise — you will be out of coverage for most of it.
  • Tell people at home you will be uncontactable before you board rather than after.
  • Any satellite wifi the boat offers is slow, metered and priced separately. It is for emergencies, not for uploads.
  • Watch the plan validity window: a short-duration plan can expire while you are at sea and unable to top it up.

Connectivity Guide by Dive Site

Blue Corner

No Signal

The most requested dive in Palau, a drift dive along the reef edge. Remote location, zero mobile coverage, and boats coordinating by VHF radio.

Blue Corner sits out at the reef edge off the southwest of the archipelago. There is no settlement anywhere near it and therefore no reason for a tower to exist there. Plan the day as offline, and upload once you are back on land.

Connectivity:

  • • At dive site: No signal
  • • Dive boat radio: VHF only
  • • Emergency: the boat's own comms
  • • Back in Koror: Full 4G

eSIM Usage Tips:

  • • Download dive site maps before trip
  • • Upload photos between dives in Koror
  • • No data needed during actual dives
  • • Perfect for post-dive social media

Jellyfish Lake

Minimal Coverage

The marine lake famous for its golden jellyfish, out in the Rock Islands. Remote location, weak to no signal. Most visitors snorkel without needing a connection.

Check before you book, not after:

Jellyfish Lake is not permanently open. The golden jellyfish population collapsed during a severe drought and the lake was closed to swimmers for a period before reopening as the numbers recovered. It has been managed that way since — open when the population supports it, restricted when it does not. Do not build a trip around it on the strength of a web page, this one included. Confirm the current status with Koror State and your tour operator when you book.

Connectivity:

  • • At lake: Minimal to none
  • • Boat departure point: Weak
  • • Rock Islands: No towers
  • • Return to Koror: Full 4G

Planning Tips:

  • • Book permit before trip (needs data)
  • • Download jellyfish info offline
  • • Tour operators know timing without GPS
  • • Upload photos after returning

German Channel

No Signal

The well-known manta ray cleaning station. A deep, remote channel with zero mobile coverage — perfect for an uninterrupted manta encounter.

German Channel is a cut through the barrier reef, made by German administrators early in the twentieth century so boats could reach Angaur. It is well offshore and uninhabited. Boats coordinate by radio, which is what radio is for.

Coverage:

  • • At dive site: No signal
  • • Remote channel location
  • • Boat coordination: Radio only
  • • Emergency: the boat's own comms

Tips:

  • • No data needed during dive
  • • Capture manta encounters on camera
  • • Upload in Koror evening
  • • Enjoy electronics-free diving

Peleliu (WWII Dive Sites)

The southern island of the 1944 battle, reached by boat or a short flight, with wrecks offshore and a landscape that is still largely a war memorial. The dive sites are offshore and unconnected.

Coverage: we have no source for mobile coverage on Peleliu and will not invent one. Go assuming a day without data, and ask your operator if being reachable matters.

Rock Islands (UNESCO Site)

Rock Islands Southern Lagoon was inscribed on the UNESCO World Heritage List in 2012 — 445 uninhabited limestone islands in a lagoon, protected for both nature and archaeology. Nobody lives there, so nothing has been built there, mobile towers included.

Tip: download maps and anything you want to read while you are still in Koror.

Milky Way (Mud Baths)

The well-known white limestone mud bottom used as a natural spa treatment. Remote Rock Islands location, no signal. Tour boats coordinate pickups without needing data.

Photos: upload once you are back in Koror, not from the boat.
