The UK saw its first, belated, 4G network appear for use late last year thanks to EE, which managed to wangle approval from regulator Ofcom to launch an LTE service before the other main providers.
But now Vodafone and O2 have launched their new high-speed 4G networks, or, to put it another way, your mobile may soon give you quicker uploads, downloads and ping responses than your home broadband thanks to these new mobile networks.
The downside is that you're probably going to need a new phone to use this super-super-fast data connection, as many older mobiles don't have the necessary radios inside them to hook into the frequencies used by 4G systems.
Luckily for you, though, the mobile networks are falling over themselves to stock new 4G-ready phones and updated versions of popular current models, with some of the best handsets from the top makers supporting our new LTE bands.
And we've done the hard work for you, so sit back, relax and check out the best 4G phones compared.

iPhone 5

iPhone 5
The iPhone 5 is a tricky one so we're going to get it out of the way early doors. Now the iPhone 5 does support 4G, but the trouble is it does so on only a select number of frequencies.
Those chosen frequencies do appear in EE's 4G spectrum so if you fancy getting Apple's latest smartphone then you're in luck - but you choice is limited to just the one carrier.
Both Vodafone's and O2's networks don't support the required frequencies for the iPhone 5 to function on 4G - so if you've currently got this handset and are with one of these carriers you've got two options.
Either you can ditch your trusty iPhone and take your pick from the selection of 4G Android and Windows Phone handsets that are available, or you can shift over to EE. The choice, as they say, is yours.
As for the phone itself, the iPhone 5 isn't an enormous update over the previous models, but Apple doesn't need to change things to appeal to its eager fans. It's still the mobile phenomenon it always has been.

HTC One

HTC One
This is HTC's best phone yet, and that's saying something. The HTC One is 4G-ready from the offset, so can be bought on any of the networks peddling the super fast connection.
The HTC One earned rave reviews for its metallic chassis, superb low-light camera performance and the general smoothness of HTC's updated user interface, with the new HTC Sense social features also going down a storm.
This phone and a 4G data connection would make most people very, very jealous indeed.

Samsung Galaxy S4

Samsung Galaxy S4
This year's Galaxy S series update was not without controversy. Its launch event was a bizarre music hall experience that some said was rather sexist, the phone's full of so much bloatware and additional Samsung software it's been complained about on TV, but none of these whinges have stopped the Galaxy S4 shipping in record numbers and making it the most popular Android phone around today.
It's not just good marketing either, the Galaxy S4 is an excellent handset in its own right and while it may be trumped by the HTC One it's still worth a look.
The only model sold in the UK comes with a 4G-friendly radio inside it, so once you've got it, you've got the 4G power on EE, Vodafone and O2.

Nokia Lumia 925

Nokia Lumia 925
Nokia's latest Windows Phone 8 model isn't to be sniffed at just because it's not running iOS or Android, it's a decent handset with some great features and a premium build which goes hand in hand with the premium price you'll pay for 4G.
It's main attraction, and you may have spotted it in the TV adverts, is its 8.7MP camera which Nokia boasts produces the best low light pictures around - and we're inclined to agree.
The Windows Phone interface is slick and provides something very different from the Apple and Google offerings, plus support for all the key UK 4G bands means the Lumia 925 is future-proofed connectivity wise.

BlackBerry Z10

BlackBerry Z10
If you want something a little more avant garde, BlackBerry's new Z10 is also an early member of the UK's 4G phone club.
The first phone to run the company's new BB10 mobile OS, the Z10's software is a little quirky in places, but the powerful, feature-packed web browser and 4G connectivity makes it a decent contender for those after something fast and a little different.
Plus, with a relatively modest 4.2-inch display, it's one of the more pocketable modern smartphones and less of a slab than other big name models. Don't ignore it just because it's BlackBerry.

Sony Xperia Z

Sony Xperia Z
Sony's current highest-end Android model is the Xperia Z, which stuffs a lovely 5-inch display into a slim chassis, into which it's also somehow managed to include a quad-core chipset, 2GB of RAM and a 13MP camera.
It's one of the most impressive Android models around today, and is also ready for your next-gen mobile data connection thanks to featuring the required miniature internal coat hanger needed to pick up an LTE radio signal.
It operates on all known 4G bands, so you'll be free to switch providers and juggle SIMs at will.

Samsung Galaxy S4 Mini

Samsung Galaxy S4 Mini
If all these fancy smartphones are just too big for your dainty little hands then fear not, for 4G also comes in smaller packages and one of those is the Samsung Galaxy S4 Mini.
Borrowing the styling from its big brother the S4 Mini comes in at a cheaper price point but still packs a decent punch for a mid-range mobile.
A bright screen and capable camera make the S4 Mini an attractive proposition and its broad 4G prowess means its available from EE, O2 and Vodafone.

BlackBerry Q10

BB Q10
If you want traditional QWERTY BlackBerry hardware to accompany your futuristic 4G data speeds, there's only one choice (well actually there's two now thanks to the BlackBerry Q5) -- the Q10.
The phone looks like your usual old BB with its chunky keyboard and landscape display above, but comes with the updated BB10 OS for adding a bit more style to proceedings.
The phone also includes NFC support, for transferring mobile data rather more slowly over distances of a couple of centimetres, should that ever really become a thing people want to do. Oh and it'll work on EE, O2 and Vodafone - phew.

Nokia Lumia 820

Nokia Lumia 820
The Nokia Lumia 820 may not be the newest phone on the block, but its strong spec sheet and hardy design coupled with its wide ranging 4G capabilities means Vodafone, O2 and EE all stock it.
The weight and dimensions of the Lumia 820 are among its core strengths. It feels heavy enough to take a knock or three, but light enough that you don't notice it in your pocket.
Likewise, if you're one of the people that think phones are getting a little too big these days, you'll appreciate the smaller 4.3-inch AMOLED screen.

HTC One Mini

HTC One Mini
Another "mini" 4G handset to break into the ranks is the HTC One Mini, arriving on EE and O2 - but currently shunned by Vodafone.
Would we recommend the One Mini? Absolutely. We love the aluminium shell, the UltraPixel camera and BoomSound speakers.
