About Three
Three (three.co.uk) is the UK operator “3”, specialised in mobile telephony and connectivity, with a catalogue of high-end and mid-range phones (iPhone, Samsung Galaxy, Google Pixel, Motorola, HONOR), tablets and accessories, plus SIM Only tariffs, contract plans and Pay As You Go options. On its website you can compare deals by handset, choose handset financing with a plan (airtime plans), sign up for unlimited data, and manage upgrades if you’re already a customer.
Beyond mobile, Three sells home broadband solutions (Home Broadband) and mobile connectivity (Mobile Broadband), designed for people who want internet without a traditional installation or need a router/mi-fi for work and travel. It’s common to find campaigns with months at 50% off, savings for switching, trade-in rewards (handing in your old phone), and promotions with cashback or free gifts on specific models.
Buying on three.co.uk is often a great option if you’re looking for aggressive handset-with-plan deals, discounts for switching provider, and the convenience of bundling mobile and internet with one provider. The site also highlights specific sections such as student discounts, upgrades for existing customers, and money-saving bundles on certain handsets and 24-month plans.
