It is most likely that your cruise ship is using Inmarsat satellite telephones for shore-to-ship calls. Some years ago, Inmarsat used different codes depending on which ocean the ship was in, but now Inmarsat uses the single code +870 for all calls. However, it is also possible that the particular cruise ship you are trying to reach is using a different satellite provider.
Note that calls to Inmarsat and other satellite services tend to be far higher than calls to ordinary land-based numbers, in the range of several U.S. dollars per minute.
