During this time VHA will introduce new offers and services aimed at winning new business.

Dews said Vodafone and 3 customers have "everything to gain" from the proposed merger.

"VHA will be a stronger mobile operator that is better positioned to compete in the Australian telecommunications market," he said, adding VHA plans to draw on the best offerings of Vodafone and 3.

For competitive reasons the companies will not market the full roadmap of handset and mobile broadband products and prices, Dews said.
