Telstra is prepared to pull the pricing lever and change its mobile plan offers to fend off its competitors looking to take advantage of the telecommunications giant's recent network outages and lure customers away. Vodafone Australia last month offered customers switching from rival networks a free month of mobile services - the offer lasted one week and expired in March 29. Asked whether Telstra would consider reviewing its plans in response to its rivals' moves, chief operations officer Kate McKenzie said the telco was constantly revising its offers.
