You’ll need a 5G-ready device to access Three’s 5G network. This can either be a 5G smartphone that you buy from Three or it can be an unlocked 5G smartphone that you purchase elsewhere (e.g. on a SIM-free and unlocked basis).

5G Devices

If you’re looking for a new 5G-ready smartphone, the following handsets are currently available to purchase from Three:

As an alternative to buying your handset on contract from Three, you could also buy a 5G smartphone elsewhere from other mobile phone retailers. With any unlocked 5G-ready smartphone, you’ll be able to access 5G coverage on a SIM-only deal from Three. You’ll just need to make sure your 5G device has support for band n78 (3500MHz) spectrum.

5G Download Speeds

According to Three, they’re building the UK’s fastest 5G network. They claim this is because they have the largest amount of usable 5G spectrum: something that’s vital for transmitting data and for delivering high download speeds on 5G.

In total, Three has 140MHz of usable 5G spectrum. This compares to 50MHz on Vodafone and 40MHz on both EE and O2. A single 5G carrier of 100MHz will be offered at launch by Three. This means Three is potentially able to offer download speeds that are twice as fast as what’s available on other UK mobile networks.

Three says they have much more 5G spectrum than any other UK network.

Three says they’re backing this up with a fully virtualised cloud-core network, multiple distributed edge data centres and next-generation radio access technology (64T64R Massive MIMO). This should help to give better 5G performance along with reduced latency and greater reliability.

So far, real-world download speeds have only been measured on Three’s 5G network in London. For their 5G home broadband service in London, Three says their customers were to access an average download speed of 232Mbit/s (compared to 30Mbit/s on their 4G network). On occasions, customers were able to access peak download speeds of 1.1Gbit/s (1,100Mbit/s). We’re looking forward to seeing actual numbers for the 5G mobile service, particularly outside of London.

According to Three, all of their price plans are offered without a speed cap so customers can always access the maximum available speed. This differs from other mobile networks like Vodafone where you’ll need to pay a little extra for uncapped download speeds on 5G.

5G Coverage

At launch, Three will be offering 5G mobile coverage in 66 UK towns and cities. This is a decent increase on the 25 towns and cities that they originally promised would get access to 5G (albeit, the launch was delayed by two months from the original date)

The following UK towns and cities are confirmed to be getting 5G coverage on Three:

Keeping Your Phone Number

If you’re switching from another mobile network to Three to take advantage of their 5G service, it’s a straightforward process to keep your current phone number.

Start by asking your current mobile network to provide you with a PAC Code. This can be obtained by texting PAC to 65075, or by requesting it online through your mobile network’s website or app. You can then order your new 5G phone or SIM card from the Three website.

Once your new phone or SIM card has arrived, you’ll need to fill out this form on Three’s website. Once you’ve submitted the form online, the transfer of your phone number will be scheduled (normally for the next working day).

For step-by-step instructions on how to transfer your phone number to Three, please select your current mobile network from the drop-down menu below:

  • Hi Ken! First of all, I would like to say that your articles are awesome. Incredibly insightful and with a lot of super useful information. As I work in the industry, I often use your blog as a point of interest in finding out the latest news. So, thank you for that!
    Now, kind of unrelated to this article, but I tried accessing the one about the roll-out of 5G on Tesco Mobile and am unable to do so – it directs me to the link of an image. Any chance you might know why? Would be very keen to read that one. Thanks! 🙂

    • Hi Mia,
      Thanks a lot for the kind words and feedback about the site! Thanks also for letting me know that the link to the Tesco Mobile 5G article is broken. It should hopefully be fixed now – thanks a lot again!
      Ken
