Buying a S7 in Ghana to use in South Africa

[Pieter Swart]

I bought a Samsung S7 in Ghana as my phone fell a few floors and was shattered. Needed a replacement phone immediately. Bought a S7 from a Samsung store in Ghana with the understanding that I can use it when I an back in South Africa. But it now seems that the country setting is Ghana and that when I use it in SA all regional settings relate to Ghana? Can this be fixed?
