Three is the only UK mobile provider to offer unlimited data on 4G, and it has a wide choice of SIM-only deals and pay-monthly contracts with the latest mobiles and tablets, as well as several pay-as-you-go options.
Three is a popular mobile provider, with a 12% share of the UK mobile phone market. It may be smaller than rival networks EE, O2 and Vodafone but it punches above its weight with competitive 3G and 4G deals. It also offers useful features, like unlimited data and free use of your phone in 16 international destinations.

Three also are now running a truly unlimited data offer called the All In One Plan but it is rather pricey at £15/month. However, they are one of the only networks to allow unlimited data with no fair usage policy on pay as you go. You also get 300 minutes and 3000 texts included in your £15 top-up.
