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.
The iPhone 5S isn't as tricky as the iPhone 5 because, along with the iPhone 5C, it supports the most 4G bands of any smartphone currently on the market. This means it will happily play with any 4G network here in the UK.
It's not all plain sailing though, as O2 still needs to do some work to its 4G service before the iPhone 5S will work on its superfast network, although we're told this will be sorted "soon".
Meanwhile over at Vodafone and EE all is well with the 5S, and Three tell us Apple's latest flagship will also play nicely with its 4G when it's launched in December.
As for the phone itself, the iPhone 5S isn't an enormous update over the previous models, but Apple has managed to squeeze a faster A7 processor inside the chassis, along with an updated camera module and a nifty fingerprint scanner hidden under the home button.
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
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'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.
