Telcos CallPlus and Slingshot are defecting from Vodafone in favour of Telecom in a move to cut costs.
Mark Callander, chief executive of the CallPlus Group, said the switch to Telecom's XT network would give both business (CallPlus) and residential (Slingshot) customers faster, flexible and more competitively-priced mobile services.
“The use of smartphones has grown dramatically in the last couple of years and they are now an essential tool for many people. The Telecom network is designed for smartphones and moving mobile data around the country at ultra-fast speeds," he said.
According to Callander, independent research determined the Telecom XT network in central Auckland had the best download and upload speeds for users accessing the web on their mobile phones.
“We have some big ambitions for driving growth in mobile services over the next few years and we believe the Telecom Wholesale team is the right partner to help us achieve these goals.
"Soon we’ll be able to offer even better data plans and we will also be launching some new smartphone and group data packages."
