VVS true on the infrastructure costs.
However,the mobile industry took off in year 2000 in Kenya's case unlike Singapore where its been in operation for long.Most mobile companies have built on infrastructure from Zero to the current case where we have ,clear calls,sms,mms,3g internet,MPESA,Mpesa agents in your estate,paybill etc.All these costs a lot of money.
I just think they want to recoup their investment money TODAY as opposed to slowly over the next 10yrs.
I think the same goes for Fibre Optic investments in Kenya and why Kenyan ISPs don't want to lower costs today.
Formally employed people often live their employers' dream & forget about their own.
