I've just come back from my trip and I'm happy to announce that I've managed to buy some MCP sim-cards for my collection. Sims were offerred at the reception desk of a ferry. I was informed that this sim will not work if a registration form won't be sent to the operator. It may take 1 or 2 days till the sim besomes active. Unfortunately one needs to be a crew member (this needs to be stated in the form) in order to ask for an activation. I haven't seen this form and I don't know the prices of calls and sms. The sim-pack costs 5Eur. I don't know if there is any credit included. Call credit is valid for 9 months. According to the attached leaflet the top-up vouchers are available on-board of a ship, however I haven't seen any.
Anyway - another nice and rather rare, but completely useless item in my collection
