Mobinil, Vodafone & Etisalat Rating War
• By nine years of controlling the market, Mobinil and
Vodafone got through a cooperative agreement that they
would settle the market in a level of around 40 pt per
min rate.
• By the first of May 2007 a third negotiator came on the
table claiming for his slice of the pie which was Etisalat.
• Etisalat came to the market with a Growth strategy that
is targeting the Market Share; so they adopted to go
through a price war against the other Market
Negotiators, which was Mobinil & Vodafone.
• This non cooperative approach leaded to an enormous
change in the price level per min rating.
