The two also gained market share at the expense of Vodafone, whose network was struck by problems. It lost 630,000 mobile accounts between June 2010 and June 2012. After the initial flurry of offers, the carriers have quietly begun reducing the discounts. Since March 2011, the cost of mobile contracts has been increasing as handset subsidies disappear, say Credit Suisse analysts. ''On average, handset subsidies are 22-37 per cent lower in July 2012 versus late 2010. The most drastically reduced subsidies are in the $49 plans, where Telstra has removed the plan altogether and Optus has cut subsidies by 37 per cent,'' the analysts wrote in a note to clients. The price war has ebbed as Vodafone concentrates on rebuilding its network while Optus and Telstra feel comfortable enough with their customer growth to ease competition for new customers. The Credit Suisse team expects handset subsidies to be between 16 and 21 per cent lower in the second half of 2011-12 than in the six months before Christmas 2011.
