Compare O2 Deals

O2 in 1985 became one of the original two mobile phone networks, along with Vodafone, and today is the commercial brand of Telefonica UK. O2 offers monthly mobile phone and SIM only contracts and has a customer base of 23 million customers.

According to Ofcom, O2 has the highest customer satisfaction for any mobile provider, an achievement it has attained for seven years in a row. After sales customer service is available during daylight hours, seven days a week.

O2 provides 2G, 3G and 4G internet access, with the latter requiring a 4G smartphone, 4G SIM card and 4G tariff. To help customers manage their internet/data usage, the My O2 app can be download for free.

The Priority app gives all O2 customers access to perks such as £1 Lunch on Monday, your favourite Channel 4 shows available 48 hours before they air on TV and the option to get tickets to music, comedy and sports events 48 hours before they go on general release.

O2 Wifi, with 10,000 UK hotspots, means that O2 customers don’t need to use up their data allowance and O2 Wifi is up to 10 times faster than a normal mobile connection. O2 customers can also access London Underground Wi-Fi, which is available in over 250 London underground stations in the ticket halls, escalators and platforms.
