Launched to the public in January 2017, Sky Mobile operates as a full MVNO (Mobile Virtual Network Operator) within the UK, utilising the O2 radio access network infrastructure.

Orange UK was a mobile network operator and a former internet service provider in the United Kingdom, launched in 1993. In 2000, it was purchased by France Télécom (now Orange S.A.), which then adopted the Orange brand for all its other mobile communications activities.

Orange UK has since merged with Deutsche Telekom's T-Mobile UK to form a joint venture, EE. EE continued to operate the Orange brand until February 2015, when new connections and upgrades on Orange tariffs were withdrawn. Existing Orange customers who wish to upgrade must switch to an EE tariff when their contract term ends, or can choose to remain on their existing Orange tariff without renewing.
