Yes, there's frustration, then there's the insult of being told that I should have known my phone was "connecting to a satellite". Seeing as how its 4G, that's physically impossible. Yes, so it turns out the ferry companies use a Telenor satellite service, and rebroadcast it using a 4G cell onboard when out of terrestrial 4G coverage. But why? Who in their right mind is going to sign up to accept charges of €17/MByte when there's Wifi onboard? It's clear that access should be denied to this network by Three until the user has explicitly opted-in to these charges. A warning SMS from Three that may or may not be received or seen (e.g. if your phone is in your bag) is not good enough. In the meantime your phone has performed a couple of background data tasks and BAM you've run up 3MBytes = €50+VAT - at which point Three are well able to cut off your data. Why not *before* you run up these charges? Perhaps because ComReg stipulate that max amount, and they realize most customers will feel stupid that they missed this particular "gotcha!", and take the hit. Not a great way to retain subscribers though.
Anyway, to answer your question - I spoke with a number of Three's Care Team over the space of a few hours, escalated my complaint and eventually was told that the satellite charges were waived/credited, though I can't confirm this until my next bill.
