Hi Peter,
it's difficult for sure, but lucky enough whatsapp works with Oman (not skype, though) and for OKC skype is working, so we can see the grandchildren and talk to our far away families.
I remember in 1976, when I went to Mexico, snail mails with the families in DK and FRA, telex with the head quarters in Munich! All those beautiful stamps I sent to my wife from Australia in 1975 (6 months down under)!
Take care
