Network and Services
Three UK has a national roaming agreement with Orange, which was later replaced by EE in 2010. This allowed Three customers to access 2G coverage in areas where their own network wasn't available.
In the past, Three used Orange's 2G network as a fallback, but this service started to be removed in 2010, affecting older phones that only supported 2G. As a result, these phones lost access to the Three network.

Three has been investing heavily in its network, including a £2billion investment programme announced in 2018 to support the rollout of 5G. This involved acquiring spectrum for 5G and creating a dark fibre network to connect new data centres.
Three's 4G network was launched in 2013, initially in London, Birmingham, Manchester, and Reading, before expanding to over 450 locations by the end of 2014. The network provides LTE and DC-HSDPA service as a standard feature to all its subscribers.
Network
Three UK has a long history of providing network coverage across the UK, and it's still going strong today.
In the early days, Three maintained a national roaming agreement with O2 to ensure coverage parity with other networks. This agreement was in place until Orange was selected as the new national roaming partner in May 2006.
Three's 3G network was rolled out in conjunction with Orange 2G, which was used as a fallback in areas where 3G wasn't available. However, this fallback coverage began to be removed in 2010, affecting older phones that only supported 2G.
By 2013, Three no longer provided a significant 2G fallback for most of the UK. This change was likely due to the increasing adoption of 3G and 4G technologies.
In 2010, Three launched a joint venture with T-Mobile called Mobile Broadband Network Limited (MBNL), which aimed to combine their 3G networks and provide almost-complete 3G population coverage by the end of 2008. This partnership was successful, with the network reaching 12,000 combined sites by November 2010.
Three has continued to invest in its network, with a £2billion investment programme announced in November 2018 to support the rollout of 5G across its network. This included the acquisition of spectrum for 5G and the creation of a dark fibre network to connect 20 new data centres.
Here are some key frequencies used by the Three UK network:
Virtual Operators
The Three network has been used by several mobile virtual network operators (MVNOs) in the past.

Three UK also launched its SMARTY network in August 2017.

Roaming and Benefits
Roaming at domestic prices was available to Three subscribers in various countries until 2009, but was relaunched in 2013 as "Feel At Home" for UK customers visiting certain countries.
The service was expanded to cover 59 countries and territories since 2017, and is now known as "Go Roam". Three advertises that the service covers "71 destinations", counting multiple countries and territories more than once.
Three changed its terms and conditions in September 2021, meaning that customers acquiring new contracts or updates after that date will no longer have "Go Roam" free of charge.
Roaming at Domestic Prices
Roaming at domestic prices is a game-changer for frequent travelers. Three UK's "Go Roam" service allows you to use your allowances abroad just like at home, without any additional charges, covering 71 destinations worldwide.
You can roam at no extra cost in 71 destinations worldwide, including popular destinations in Europe, the USA, and beyond. Three UK's "Go Roam" service was previously known as "Feel At Home" and "3 Like Home", which was launched in 2009 and 2013 respectively.
The service was expanded to a further 24 European countries in September 2016, and later to 59 countries and territories in 2017. Three UK counts several countries more than once, so it advertises that the service covers 71 destinations.
However, it's worth noting that Three UK changed its terms and conditions in September 2021, so new customers won't get "Go Roam" for free. Instead, it costs £2 per day for roaming in EU countries (except Ireland) and £5 per day when roaming outside the EU.
