Viet Nam News, a national English daily, has revealed Viettel has slashed off-peak call charges by 75% as it seeks to ignite demand and attract more users. The military-run cellco said the new charges were down to VND500 (USD0.03) a minute for calls between Viettel subscribers and VND1,000 for calls to other networks – the lowest rates in a highly competitive market. Managing director Tong Viet Trung said that the company was able to make such drastic price cuts because its network and services were running at optimal levels, enabling them to reduce operating costs. ‘We hope promotion will increase the number of Viettel subscribers from 15 million to 22 million by year end,’ he added. According to TeleGeography’s GlobalComms database Viettel is the country’s largest wireless operator by subscribers. It plans to install an additional 4,000 base transmission stations in 2008, bringing the total number to 10,000.
