Ohayu: does it work on a cruise?
Short answer
Ohayu is a Cyprus-registered eSIM app, published by Kridelo Limited. It sells data-only travel plans for more than 170 destinations. A built-in cashback scheme called Ohayu Credits gives you 5% back on every purchase. Plans run from small single-country packages up to 50GB bundles. You can activate any of them within 30 days of buying. The app holds a 4.7-out-of-5 rating on the App Store, built on praise for fast support. Ohayu has no maritime plan, so its coverage stops at the coastline.

Overview
Kridelo Limited develops and publishes Ohayu. The company is registered in Nicosia, Cyprus. You'll find the app on iOS and Android, plus a companion website. Ohayu is a straightforward, data-only travel eSIM covering more than 170 destinations. There's no phone number, no cellular calls and no SMS on any plan. For voice, you'll need an app like WhatsApp, FaceTime or Skype instead.
Ohayu's standout feature is Ohayu Credits. Every purchase earns you 5% back, which you can spend on a future plan. There's also a referral scheme. Refer a friend and they get $3 off their first order. Prices show upfront in your chosen currency, including GBP, before you check out.
The app holds a 4.7-out-of-5 rating from around 74 App Store reviews. Reviewers often name individual support staff by name. Those staff have fixed activation problems in minutes. That kind of speed is rare for a company Ohayu's size.
Coverage on a cruise
Ohayu is a land-only eSIM. Its plans connect to local mobile networks in each destination. Like any land provider, it goes dark once a ship passes about 12 nautical miles from shore. It only reconnects as the vessel nears its next port. Say you buy an Ohayu eSIM for a stop in Japan or France. You're really buying data for the hours you spend ashore in that country. Validity only begins when the eSIM first connects to a local network. It doesn't start the moment you pay.
Plans and pricing
Prices were checked on ohayu.com in September 2026. Plans range from about $9.49 up to $84.49. Data caps run from 2GB to 50GB. A 15GB monthly plan costs $39.99. A 25GB monthly plan costs $49.49. Both run on 5G where the local carrier supports it.
You can activate a purchase any time within 30 days of buying it. At checkout, there's an auto-top-up option too. It suits travellers who'd rather not watch a shrinking data balance. Every purchase also earns you 5% back as Ohayu Credit. Over time, that works out as a discount for repeat buyers.
Not every eSIM phone is supported here. You'll need an iPhone XR or later, or an eSIM-capable iPad from 2019 onward. Your device also needs iOS 16.6 or newer. If your phone is older, check Ohayu's compatibility list before you pay.

Setup and activation
You buy and install Ohayu from inside its own app. Download it before you leave, while you're still on home Wi-Fi. That way, you can pick your destination and add the eSIM profile ahead of time. Validity only starts once the eSIM connects to a real network abroad. The purchase date has nothing to do with it. So install it early, then leave it sitting unused. Wait until the ship reaches its first port to use it. That way, you won't lose any of your paid data window.

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.
Verdict
Ohayu is a tightly built, app-first eSIM seller. Its cashback and referral perks reward you for buying again and again, not just once. The 30-day activation window suits someone planning port stops well ahead of a cruise. So does the Ohayu Credits scheme. Before relying on it, check two things. Make sure your phone meets the hardware requirement. And look closely at 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.
