Suncorp is reported to have returned to Telstra in a view to facilitate its mobile voice and data services over the next three years, following a brief stint with Telco’s main rival, Optus.

Telstra announced to restore its long-standing relation with the financial services group to facilitate a portfolio of hardware devices to hire and refresh the Next G network wireless data cards.

According to Telstra, the deal involves the deployment of smart phones and Turbo Elite modems that aim to offer a faster mobile broadband service.

Suncorp's group executive for business technology Jeff Smith posted that the decision to return to Telstra's services was extended on the grounds of the geographically diverse performance of the Telstra Next G network.

"As a service-based organization, responsiveness regardless of geographical location is critical. The Telstra offering gives us the breadth of coverage, reliability and technological advancement we require," Smith quoted.

It is posted that only 45 percent of Suncorp’s products were smartphones, while the remaining was adorned by standard mobile phones.

In addition, Telstra aims to further facilitate the bank's mobile ATMs over the Next G network, linking to the core network.
