Stena Line: Wi-Fi and eSIM on board
Short answer
GigSky sells a Stena Line ferry eSIM. It connects to the vessel’s onboard network for the crossing, and GigSky is the only provider selling ferry-branded plans at all. Red Bull MOBILE reaches several of the same fleets through Telenor Maritime without branding them by operator. Take 10% off with ESIMDUDE.

About Stena Line
Stena Line is the operator you meet most often if you move around northern Europe: the Irish Sea, the North Sea and the Baltic approaches are all theirs. The routes vary from a three-hour hop to a fourteen-hour overnight, and the connectivity answer varies just as much.
The ships you will actually be on
The Irish Sea runs the E-Flexer sisters Stena Estrid, Stena Edda and Stena Embla, plus Stena Superfast VII and VIII on the Belfast–Cairnryan route. Harwich–Hoek van Holland uses Stena Britannica and Stena Hollandica, two of the largest ferries in the world. Gothenburg–Kiel is worked by Stena Germanica and Stena Scandinavica.
Crossing-specific detail — how long you are out of range, which carrier you land on at each end, and whether the operator sells anything onboard — is in the route guides.
Where the signal actually dies, route by route
Crossing length is the whole story on a ferry. A ninety-minute Channel hop keeps a land signal most of the way; a sixteen-hour North Sea overnight does not. Here is every Stena Line route that matters, with what to expect on each.
| Crossing | Duration | What your phone does |
|---|---|---|
| Gothenburg–Kiel | ≈14 hours, overnight | The offline one. You run down the Kattegat and across the western Baltic overnight, with long stretches beyond terrestrial reach. |
| Harwich–Hoek van Holland | ≈7–8 hours | A North Sea crossing with a genuinely dead middle. Expect coverage for the first hour and the last, and nothing useful in between. |
| Holyhead–Dublin | ≈3h15 | The Irish Sea is narrow enough here that you often keep a weak signal from one side or the other, but the middle 45 minutes is unreliable and frequently drops entirely. |
| Belfast–Cairnryan | ≈2h15 | Short, and the North Channel is narrow. Coverage holds for much of the crossing, which makes this the least problematic route on the network. |
| Fishguard–Rosslare | ≈3h30 | St George’s Channel. Similar to Holyhead–Dublin, with a dead middle section of around an hour. |
| Gothenburg–Frederikshavn | ≈3h15 | Crosses the Kattegat. Swedish coverage at one end, Danish at the other, an unreliable stretch in between. |
What the onboard Wi-Fi is actually like
Stena provides onboard Wi-Fi across the fleet, with paid upgrade tiers on longer routes. The Irish Sea crossings dip out of reliable land coverage mid-channel; the Gothenburg–Kiel overnight is fully offshore for much of the night.
Stena provides onboard Wi-Fi across the fleet, with paid upgrade tiers on the longer routes — the structure most ferry operators have converged on. On the short Irish Sea crossings the backhaul is largely coastal, which is why it performs better than you might expect; on Gothenburg–Kiel it is satellite, and it performs accordingly.
The Stena Plus lounge on some routes includes connectivity among its perks, which can be a cheaper route to a usable connection than buying a Wi-Fi package outright if you were considering the lounge anyway.
Ferry Wi-Fi tiers and prices change without announcement, so treat any figure you see quoted online — including ours — as indicative and confirm it at booking.
What a land eSIM covers at each end
Vodafone and Three in Ireland and the UK, KPN and Vodafone in the Netherlands, Telia and Telenor across Scandinavia. A European regional plan covers every Stena port — but as with any UK-touching route, confirm the UK is included and not sold separately.
Our recommendation for Stena Line
Buy the GigSky Stena Line plan for Gothenburg–Kiel and for Harwich–Hoek van Holland, where you have real hours of nothing. For the Irish Sea crossings, a European eSIM plus accepting a patchy 45 minutes mid-channel is the proportionate answer, and it costs you nothing extra if you already carry one.

Stena Line connectivity FAQ
01Is there an eSIM for Stena Line?+
Yes. GigSky sells a Stena Line-branded ferry eSIM that connects to the vessel's onboard network during the crossing — it is the only ferry eSIM product in the market, and Stena Line is one of just four operators covered.
02What is Stena Line Wi-Fi like?+
Stena provides onboard Wi-Fi across the fleet, with paid upgrade tiers on longer routes. The Irish Sea crossings dip out of reliable land coverage mid-channel; the Gothenburg–Kiel overnight is fully offshore for much of the night.
03Which routes does Stena Line run?+
Holyhead–Dublin, Fishguard–Rosslare, Cairnryan–Belfast, Harwich–Hook of Holland, Gothenburg–Kiel, Gothenburg–Frederikshavn
04Will my normal eSIM work on a Stena Line crossing?+
Near the coast, yes — for the first and last stretch of the crossing you will hold a land signal. In open water it will show no service, because there are no masts out there. How much of the journey that affects depends entirely on the route length, and on Stena Line that ranges from ≈3h15 to ≈14 hours, overnight.
05Which Stena route most needs a ferry eSIM?+
Gothenburg–Kiel, without much competition. Fourteen hours overnight across the western Baltic puts you beyond terrestrial coverage for the great majority of the sailing, and unlike the Irish Sea routes there is no nearby coast to fall back on. Harwich–Hoek van Holland is the second candidate at seven to eight hours across the North Sea.
06Will my phone work on Holyhead–Dublin?+
Intermittently, and better than most people expect. The Irish Sea is narrow at that point, so you frequently hold a weak signal from the Welsh or Irish coast for much of the three-hour crossing. What you should not expect is a stable connection through the middle — plan for roughly forty-five minutes of nothing and you will not be caught out.
