Sheffield-based Uber has been retained for a further 12 months and will commence on work immediately.
The agency has been briefed to devise, create and produce innovative in-store and point-of-sale material for 3's network of independent, specialist and mass-market mobile phone stores such as The Carphone Warehose and The Link.
Uber began trading in mid-December last year and was formed by Greg Clark, Richard Benjamin and Pamela Cocke out of the closure of The Source, which shut up shop last year.
Uber took the majority of The Source's clients such as Sony, Universal, Morphy Richards, Epson, Bosch and DFS.
