Is there mobile data while diving or on boat trips?

Only near shore. Around Naha and the resort coasts you'll have signal, but out at the Kerama Islands and on dive boats coverage is patchy to none, so screenshot dive-shop details and departure times beforehand.

Do I need a car in Okinawa, and will navigation work?

Outside Naha's Yui Rail monorail there are no trains, so most visitors rent a car. The eSIM powers live navigation across Okinawa's main island, though you should cache maps before heading to the far north or remote capes.

Good to know in Okinawa

Beyond Naha's monorail there are no trains, so most visitors rent a car; keep your eSIM active for real-time navigation, and cache ferry schedules before island-hopping to Ishigaki or the Kerama reefs.

Best time to visit Okinawa

April to early July and October offer warm seas and clear diving; try to avoid the August-to-September typhoon peak.

Two simple ways to buy

Okinawa eSIM plans: unlimited, or by the GB.

Every Okinawa eSIM from My Holiday SIM is one of two straightforward types. Pick whichever fits how you travel in Okinawa — you can always top up or switch on your next trip.

Unlimited plans

High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

Best for streaming, video calls & hotspot
Great for longer or open-ended trips
One price per day — no GB anxiety

By-the-GB plans

3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

How much data do you need in Okinawa?

A rough, honest guide to sizing your Okinawa eSIM so you're not guessing. Most travellers in Okinawa are comfortable on 3–5 GB a week — heavy streamers just go Unlimited.

Okinawa eSIM: your local data guide.

Okinawa's subtropical islands pull you from Naha's Kokusai-dori shopping street to the whale sharks of Churaumi Aquarium, the coral reefs off the Kerama Islands and white sands on Ishigaki. Ferries, dive boats and rental cars are the way around, so an Okinawa eSIM keeps maps, dive-shop bookings and ferry timetables working far from the mainland.

One eSIM for Okinawa and all of Japan. It's the national Japan eSIM — from $3.14/day with unlimited data, working the same in Okinawa as it does the moment you leave it.

Landing at Naha Airport (OKA)?

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.

Across the region

Where you'll lean on data in Okinawa.

Naha

The island capital and its Yui Rail monorail run on strong 4G and 5G, fine for streaming and ride-hailing.

Motobu (Churaumi)

Coverage around the aquarium and Ocean Expo Park is reliable for navigating and uploading whale-shark photos.

Ishigaki Island

The main town has good signal, but it thins on the jungle roads and remote beaches, so cache maps first.

Kerama Islands

On these dive islands and the ferries out, expect patchy data, so download charts and bookings before you sail.

The practical bit

Getting around Okinawa on your eSIM.

Apps you'll want online in Okinawa

Yui Rail— Naha's monorail app for the only train line on Okinawa's main island.
GO— Book taxis in Naha and around the resort areas by app.
DiDi— Alternative taxi-hailing app operating in Okinawa's main towns.
Google Maps— Essential for driving directions once you leave Naha by rental car.

How long to stay in Okinawa

A typical Okinawa trip runs four to six days, combining Naha and the Churaumi coast with a night or two out on Ishigaki or the Kerama Islands.

How much data for Okinawa

A balanced 3-5 GB covers navigation, ferry bookings and sharing beach and diving photos over a week; choose Unlimited if you'll stream or hotspot other devices on the islands.

Coverage in Okinawa

Naha and the main resort coasts have dependable 5G, yet signal weakens on the outer islands' remote beaches, jungle roads, the Kerama dive sites and on the inter-island ferries.

Okinawa eSIM questions, answered.

Yes, the main towns on Ishigaki and Miyako have good coverage, and the same national Japan eSIM works there. Signal thins on remote beaches, jungle roads and on the ferries, so download maps and tickets before you travel.
