The O2 brand, which succeeded One2One in 2002, has been owned by Spanish giant Telefónica since 2006. In December 2013, it became one of the first providers to bring the 4G service to the UK, offering customers crisp and undisrupted calls, browsing, texting, and downloading. Embracing the infrastructure that first launched over 30 years and continues to be developed each year, O2 offers one of the fastest roaming internet services available.
O2 customers can also take advantage of various bundles and add-ons, including packages that bring down the costs of roaming charges when abroad and tariffs for making international calls from the UK.
Clients can also capitalise on various membership benefits such as O2 Priority rewards, which include pre-sale tickets for events at the various O2-sponsored venues across the UK.
