O2 is the second-largest mobile telecoms provider in the UK after EE, with more than 25 million customers. It has been expanding its 5G coverage over the past year; the service is available to O2 customers in 20 cities including London, Edinburgh, Cardiff, Belfast, Leeds and Slough. The business is promoting the availability of additional services to subscribers, and in March 2020 announced it was the exclusive UK mobile network distributor for the highly anticipated Disney+ video streaming service. The deal means new and upgrading pay monthly customers can access Disney+ on O2 for six months, following an agreement with Amazon to provide a “Christmas treat” for O2 customers. The Amazon deal allowed customers to choose their favourite upgrades – including Amazon Prime Video or Music membership – from a range of offers.

During the COVID-19 outbreak, O2 was one of a range of telecoms providers to highlight the work of its staff to help the country “Stay Connected”, and invested in improvements to services with a focus on the NHS and key workers.
