The Telkom Citrus L05 brings WhatsApp, 4G and a touchscreen to South Africa’s familiar button phone for R299, writes ARTHUR GOLDSTUCK. Telkom says around 20-million South Africans still use 2G phones, often still throwing around slang like uTilili or uBhopopo. At R299, the Citrus L05 offers one of the cheapest routes from 2G calling into the world of WhatsApp and other everyday apps. The Citrus L05 combines a numeric keypad with a 2.8-inch touchscreen. The Citrus L05 costs R299 from Telkom stores and participating retailers.
