Thank you very much for your replies. Much appreciated.
I would prefer to use VoIP or WhatsApp but am afraid such calls cannot go to a recipient on a landline, or can they? There will be 9 days at sea in a row so no ports for that period of time.
So I suppose I will have to pay for the rather pricey ship to shore calling option. I will try to keep the duration of the daily calls down to 2-3 minutes then. It’s expensive but that this option is there is a great relief.
Thanks again!
