Cheap sea-day data on Cunard, Costa, Viking, and 150 ferries.

What you’re actually buying

eSIM.dog cruise is cheap sea-day data on Cunard, P&O, Viking Ocean, Costa, Ambassador, AIDA, and a pile of European ferries. Same idea as Red Bull’s sea-day plan. It dies when you dock. Nassau still needs a land eSIM.

100 MB is WhatsApp and maps, not a week of photos. 1 GB is a serious sea-day pack and it costs like a ship Wi-Fi day. That’s the trade. Coupon DUDEADVICE5 is 5% off. ESIMDUDE is GigSky and Saily. Don’t mix them.
