3 is one of the UK’s newest mobile phone networks. It first launched back in 2003 and specialised in 3G mobile internet in the same way that EE specialises in 4G today. They are well-known for having excellent mobile internet coverage throughout the country compared to their rival networks and, in fact, Ofcom has repeatedly rewarded them for the speed and quality of their network. They are currently one of the highest-rated networks in the UK and have about 3.5 million customers in the UK.

    How is this affected with the impending take over of o2 by Three? I’m assuming Three would also be taking the infrastructure over as well and thusly increasing coverage?

    Using 4G in London and 10/10 for coverage and speeds all arounds – upload, download and ping all ballistic. Now I am really worried if it will stay like that but have really been enjoying it immensely so far.

      What sort of figures are you seeing?

      I’ve been using three for over 4 years and for the past 1 year I’ve noticed the coverage for 4G hasn’t improved even though governments have said it is mandatory for all provides to increase coverage ar pound London, I haven’t seen a change at all from them. My phone doesn’t seem to like the three network as it randomly needs to be rebooted as I get kicked off the three network and have to re able the lease. Honestly all these network providers are as bad as each other. One reason why I haven’t changed providers is because there are none with unlimited data so yeah this is the only reason why I use them. But just to confirm the coverage indoors around London is absolutely diabolical. Rant over thank you

    That link to the 3 coverage map just looks to be a bunch of corporate spyware. It looks like the link should probably point to

      Not sure what you mean by that – the link is correct and there’s certainly no spyware. It leads to the official Three site. Try it yourself.

    Excuse me, I am very old school and not very techno savvy! How much difference is there between the coverage for phone call and the coverage for internet when it comes to three mobile?

  5. alan techno 24 February 2012 at 09:45 Permalink

    the information is inaccurate as three only works on 2100mhz 3g and ony owns a 3g network. it is also ending its 2g agreements bit by bit meaning even less coverage.

      These are the official values we’ve been provided based on population coverage. Do you have a more accurate source you could refer us to?
