Hey Priscilla,
yes indeed, I've been having to deal with this during my long visits since 2013.
For business (I'm a freelance DE>EN translator) I use email and phone calls from my Ghana mobile. Calls to European (landline) numbers are incredibly cheap from Ghana.
I don't have a big problem with the time difference, my customers in Germany are on CET/CEST, i.e. GMT +1 or GMT +2 during the European summer. (GMT = Ghana Maybe Time.)
Privately speaking, I personally detest Skype, but WhatsApp is really good, because a) it's more or less instant b) you can exchange photos and c) you can send voice recordings (if you like that kind of thing).
(I must have an internet connection at all times anyway for my business.)
Apart from that, I'm on Facebook for more general stuff with my family and friends, and email for a handful of friends who believe Facebook is the Work of the Devil. If there's anything urgent there's the phone of course.
I guess you could say keeping in touch is the least of my problems in Ghana, dum so dum so the biggest.
