Carphonewarehouse is a UK mobile phone retailer focused on smartphones and related services. It sells handsets from major brands, SIM-only plans, pay monthly contracts, and accessories such as cases, chargers and screen protectors.

Shoppers often find savings through contract and SIM-only promotions, handset price drops, and limited-time online offers. Deals can include reduced upfront costs on pay monthly phones and discounted monthly tariffs on selected networks.

Carphonewarehouse operates online and is known for comparing mobile deals across multiple UK networks rather than being tied to just one provider. Stock and offers can vary by model, network and contract length.
