GiffGaff does work in South Africa, but other areas, such as the West of Africa [Nigeria, Ghana, Gambia, Niger, Liberia, Mali, Sierra Leone, Togo etc] are not covered at this time from my understanding. Although, the jury is still out on Nigeria, as I have just sent someone a GiffGaff
SIM card who is located in Nigeria, and if they not only receive but manage to activate the SIM card, I will report back here. However, I doubt it will work there, but it's worth finding out.
And also worth noting, in South Africa, GiffGaff
Goodybags are not available, only
roaming / data. To get the most from GiffGaff(o2) it's more cost effective and better value for money with a Goodybag plan. However, roaming can still be suitable for some people, especially those who are travelling to South Africa for a temporary stay. It can also work well with permanent SA residents who want a second phone number / phone as a back up.
