Calling home three or four times during my international travels has always been enjoyable and not too costly with my providers' international calling plans. It's great to be able to give and get quick updates on daily activities.
Actually, I've tried a variety of methods for phoning home-calling cards from the respective country (not always reliable); leasing an international phone (costly); and using my own phone with the added plan which gives a discounted rate.
My provider has no discounted rate plan for Ghana, so a call will cost about $2.50/minute. It's the data rate that's the kicker- $ .0195/KB. Is that about $19/MB or is my math bad? Send/receiving pictures might produce a big bill! I will be in search of WiFi enabled facilities.
One call home to say I've arrived safely-that's it!
