Square One’s service to UK and Irish customers has evolved over the past 6 years. Since the outset, Square One has worked in a strategic partnership with Three Ireland providing customers with new connections, day-to-day account management, and excellent support from home markets. Following the acquisition of O2 Ireland by Three/Hutchinson Whampoa in 2013, Square One has invested heavily to build our own Three UK solution specifically to compliment the services offered by Three Ireland.

Three Ireland

Ireland’s fastest growing and best mobile phone network – Three Ireland provides solutions and services to enable businesses to improve their efficiency and communications, both internally and with their customers. Three offers the unique combination of product, services, consultancy and technical expertise to help transform businesses – underpinned by one provider, one bill, and award-winning Irish-based customer service.

Since launcing in 2005, Three has invested almost €2 billion in building Irish business, and in July 2014, completed a deal to purchase O2 in Ireland. Square One is Three Ireland’s sole and exclusive partner in the UK; together we offer a concerted, one-stop shop for whole-of-Ireland and Ireland-and-UK solutions – putting us in a unique solutions position that our competitors can only dream of.


O2 is one of the leading UK mobile communications companies. With over 23 million customers, O2 runs 2G, 3G and 4G networks across the UK, as well as operating O2 Wifi and owning half of Tesco Mobile. O2 has over 450 retail stores and sponsors The O2, O2 Academy venues and the England rugby team.

Square One has partnered with O2 since 2011 and been involved in some unique projects. As an example, for over a year, we successfully ran marketing campaigns combining business garnered from their retail stores with an increased flow of business connections. This program saw Square One manage all business traffic from some 30 or so stores in a vast territory that stretched across the Midlands down the M5 to Cornwall, and across the M4 corridor from Swindon to Carmarthen.
