O2

O2, British mobile operator with 5G network and device catalogue

O2 is a UK telecommunications operator that combines the sale of devices and accessories with contract and prepaid mobile plans. Its offering is built around connectivity — 5G and 5G+ network, coverage and EU roaming — and a catalogue of devices from brands such as Apple, Samsung, Google and HONOR, as well as tablets, laptops, smartwatches and headphones.

Plans and contract options

The company distinguishes between monthly payment plans, SIM Only and Pay As You Go, and includes options such as the Essential Plan and international top-up. Its commercial mechanisms include flexible tariffs, the Switch Up programme for changing devices, O2 Insure insurance, data rollover, auto-save plans and Multisave discounts. It also offers benefits linked to Virgin Media and O2 and the Volt programme.

Devices and promotions in the catalogue

The site displayed offers on models such as the iPhone 18 Pro and iPhone 18 Pro Max, the Samsung Galaxy S26 Ultra, S26, Z Flip8 and Z Fold8, the Google Pixel 11 Pro XL and Pixel 10 Pro Fold, the Apple Watch Series 12, the iPad A16 and the HONOR Pad X8b. Some promotions included discounts for trading in an old device, months of free airtime or the option to claim a Samsung Galaxy Chromebook Go. These conditions were presented with specific end dates and with price increases scheduled for certain periods, so they reflect the catalogue in force at the time of analysis.
