I was recently looking at Safaricom's Postpay Tariff details and things we simply not adding up. I was tempted to Tweet them, but decided against it because I recently pointed to them an anomaly in the search feature in the online phone shop and one clueless responder told me something I couldn't believe. Later they fixed it though!
Well, go read this -> http://www.safaricom.co.ke/personal/postpay/tariff-plans/postpay-tariff-plan - and tell me if it makes sense. I have been on their Postpay since 2007 and I never heard about a free handset. Plus, Safaricom has different categories on Postpay, which are not mentioned on this url. So I am not surprised they have what Collins has spotted.
