The event will be held at the Celtic Manor Resort in South Wales and is set to be attended by more than 850 store managers and senior management staff.
The conference aims to celebrate Phones4U’s previous year’s success and share plans for the Christmas trading period and into 2011.
It will also include an evening awards show featuring celebrities and 3D projection.
Manchester-based HGA Creative Communications was appointed in May, after producing the six previous events.
HGA live events director Ian Grime said: "We’re delighted to be working with Phones4u for yet another year. It really is a successful formula where HGA and the client work together as one team and constantly raise the bar with the standard of event production."
