My reaction to the price war was different.
I used to have a virtually dormant SCOM line that was for MPESA only.
When the war started, I found myself using it a lot... to call SCOM numbers
Even after factoring in the reduced rates, I have effectively increased my spend on SCOM line and reduced that on ZAIN.
I don't know how many other people have done the same.
BEFORE THE WAR: I used ZAIN almost exclusively for all calls
AFTER THE WAR: I use SCOM to call SCOM numbers and ZAIN for other calls
Nothing is real unless it can be named; nothing has value unless it can be sold; money is worthless unless you spend it.
