Carphone Warehouse is to close its Netherfield store from April.
The store on Victoria Retail Park is one of 531 standalone stores to shut across the UK, resulting in 2,900 job losses.
The firm says the move is not related to the coronavirus outbreak, but was because of changing mobile market.
Carphone Warehouse shops inside 305 big PC World and Curry’s stores, and these will be not affected by the changes.
Group chief executive Alex Baldock today said customers were increasingly buying online and from its big stores which sold computers and TVs as well as mobiles.
He said: “They can’t find all this in the small mobile-only stores that are one twentieth of the size; they’re visiting these less and these stores are losing more money as a result.”
