Ohayu: does it work on a cruise?
What Ohayu sells, what it works out at per gigabyte, and the specific stretches of a cruise where it is the wrong tool for the job.
Does Ohayu work at sea?
Ohayu is a Cyprus-registered eSIM app published by Kridelo Limited, selling data-only plans for more than 170 places. A cashback scheme called Ohayu Credits gives 5% back on every purchase. Plans run from small single-country packages up to 50GB, each activatable within 30 days of buying. The app holds 4.7 out of 5 on the App Store, built largely on praise for fast support. There is no sea plan, so coverage stops at the coast.

Who Ohayu is for
Kridelo Limited develops and publishes Ohayu from Nicosia, Cyprus, with apps on both platforms and a companion website. It is a plain data-only travel eSIM across more than 170 places. No plan carries a number, cellular calls or SMS, so voice means WhatsApp, FaceTime or Skype.
The standout is Ohayu Credits. Every purchase earns 5% back to spend on a future plan. A referral scheme gives a friend $3 off their first order. Prices show upfront in your chosen currency, GBP included, before checkout.
The app holds 4.7 out of 5 from around 74 App Store reviews, and the reviews have a telling quality. Individual support staff get named, having fixed activation problems in minutes. That kind of speed is rare at this size.
What happens when the ship leaves port
Ohayu is a land-only eSIM, connecting to local networks in each place. Like any land seller it goes dark once a ship passes about 12 nautical miles from shore, returning as the vessel nears the next port. An Ohayu eSIM bought for a stop in Japan or France is really data for the hours spent ashore there. Validity begins when it first meets a local network, not when you pay.
What Ohayu costs, and what that buys
Prices were checked on ohayu.com in September 2026, running from about $9.49 to $84.49, with caps from 2GB to 50GB. A 15GB monthly plan is $39.99 and a 25GB monthly plan $49.49. Both run on 5G where the local carrier allows.
A purchase can be switched on any time within 30 days of buying. Checkout also offers to refill the plan by itself, which saves keeping an eye on the balance. Every purchase earns 5% back as Ohayu Credit, and over a few trips that works out as a standing discount for repeat buyers.
Not every eSIM phone works here, which is worth checking before paying. You need an iPhone XR or later, or an eSIM-capable iPad from 2019 onward, running iOS 16.6 or newer. Anything older wants checking against Ohayu’s compatibility list first.

Getting it working before you sail
Buying and installing happen inside the app, so download it before leaving while still on home wi-fi. That lets you pick a place and add the profile ahead of time. Validity starts only once the eSIM meets a real network abroad, and the purchase date has nothing to do with it. Install early, leave it unused, and switch it on at the first port so none of the paid window is lost.

Cruise and ferry plans
The plans database on this site holds cruise, ferry and maritime products only. Ohayu publishes none, so there is no plan table on this page. Its regional data plans remain the relevant purchase for port days.
The verdict for cruise passengers
Ohayu is a tightly built, app-first seller whose cashback and referral perks reward buying again rather than once. The 30-day window suits somebody planning port stops well ahead of a cruise, as does the Credits scheme. Two things to check before relying on it. Make sure the phone meets that hardware requirement. And read closely what the refund terms actually cover.
What to pair this with for sea days
Ohayu cannot cover a sea day. One of these has to:
Frequently asked questions
01Does Ohayu work on a cruise ship?+
It works ashore and nowhere else. The practical test is whether you can see land — Ohayu uses ordinary terrestrial carriers, which reach roughly twelve nautical miles out and no further. Pair it with an at-sea eSIM.
02What are Ohayu Credits, and how much do you get back?+
Ohayu Credits give you 5% cashback on every purchase, applied automatically. You can spend the credit on a future plan bought through the same account. Think of it as a loyalty discount for repeat travellers, not a one-off promo code.
03Which phones actually work with Ohayu?+
You'll need a fairly modern phone for Ohayu to work. That means an iPhone XR or newer, or an eSIM-capable iPad from 2019 onward. Your device also needs iOS 16.6 or later. If your phone falls outside that list, it may not work. The app or its eSIM profile might not install at all.
04Does an Ohayu plan expire if you buy it before your trip is confirmed?+
No, not right away. You can activate a purchased plan any time within 30 days. Its validity window only starts once it connects to a real network at your destination. So buying ahead of a still-uncertain cruise schedule won't waste your data allowance.
05Who runs Ohayu?+
Kridelo Limited owns and runs Ohayu, a company based in Nicosia, Cyprus. You'll find Ohayu on the Apple App Store and Google Play, alongside its own website. There's no separate parent brand behind it — Kridelo runs Ohayu directly.
06Is there a Ohayu discount code?+
Yes — ESIMADVICE. 10% off Ohayu data plans Apply it at checkout and confirm the total actually drops before you pay — an expired code that silently does nothing is the normal failure here, not a rejected one.
