The operator is also trialling Samsung concessions stores in its London Oxford Street and Solihull stores
Three is set to upgrade a further 70 of its retail stores to its new format by the end of the year as well as installing manufacturer concessions in its flagship stores.
The operator has already upgraded 30 of its stores to the new format, featuring new branding and a more open plan shop floor.
CEO David Dyson told journalists at the operators first quarter business update it would be looking to refresh its retail footprint during this year to cover 30 per cent of its 349 store footprint by the end of the year.
It also is currently trialling Samsung concession stores in its London Oxford Street and Solihull stores, with plans to roll these out widely if the trial proves popular. The operator is in talks with other manufacturers about installing similar facilities in other stores.
Dyson said: “The new format stores are more welcoming and we will have refreshed 100 of our stores by the end of the year.
“We’re also talking to key partners about having more of a presence in these new stores and are trialling with Samsung in two stores currently, a partnership we expect to continue.”
