4G doesn't just mean you can post photos to Facebook faster -- it allows you to stream video from Netflix, listen to music on Spotify and download films from iTunes or Google Play, without having to tediously buffer every other second.
Contract prices for 4G have come down a lot since EE first launched back in 2012, making it much more accessible. If you've found yourself eyeing up the latest 4G deals, you'll need to make sure you've got a 4G-capable phone. To help you find the best handset, I've rounded up my five favourites.
Samsung Galaxy S4
The Galaxy S4 is Samsung's flagship phone, packing a whole host of impressive specs. Its 5-inch, Full HD display is truly stunning, making it a brilliant choice if you want to use your 4G speed for streaming movies on the go.
Inside is a powerful quad-core processor that's great for high-definition gaming, while its 13-megapixel camera is capable of producing some awesome photos. It's worth noting that the Galaxy S5 is due out in the next few months, so you may want to wait.
At 4 inches, the iPhone 5S is the smallest top-end phone you'll find at the moment. While some argue it's too small, others love its compact size. Its screen doesn't give the same space for movies, but it's very comfortable to hold and you don't need to stretch your thumbs out to type with one hand.
It's got a superb camera too, along with an intensely powerful 64-bit processor. Its iOS software is simple to use, making it a great choice for new smart phone users, or simply those of you who don't want to muck about with endless settings menus.
With its sleek, all-metal body, the HTC One is arguably the most luxurious Android phone around. The metal not only feels good to hold, it makes it look like a more premium device than its plastic rivals.
It's not just about the looks though -- the HTC One is stuffed with some impressive kit. It has a 4.7-inch Full HD display, a nippy quad-core processor and its 4-megapixel camera has larger pixels than normal, which take in more light, resulting in some great photos.
Its HTC Sense 5 software has a straightforward look to it and won't be difficult for new Android converts to get to grips with. If you want to dive into Android but want the simplicity of use and metal style of the iPhone, the HTC One is well worth a look.
Sony Xperia Z1
A 5-inch, Full HD display, a stonkingly powerful processor and a brilliant 20-megapixel camera are three headline features of the Xperia Z1. All that is wrapped up inside a beautifully stark glass and metal body, making it a great choice if stylish looks are a must.
That's not all though. The Z1 is completely waterproof -- it not only shakes off a splash, but can actually be submerged in water to 1 metre for 30 minutes. If you've ever killed a phone by dropping it in the sink, the toilet or a pint of beer, the Z1 should be on your wish list.
Nokia Lumia 1020
If you're a keen shutterbug and regularly take a compact camera out with you as well as your phone, you should take a look at the Lumia 1020. It has a whopping 41-megapixel sensor that can capture absolutely stunning photos and the manual control over camera settings lets you get creative with shutter speeds.
Uploading large image files won't be a problem on a fast 4G connection of course, but you can save smaller versions if you don't want to use up your data allowance. It runs on Windows Phone, which is easy to use, but doesn't have as many as apps available as Android or iOS.
If you're an app addict, it won't suit, but the 1020's astounding camera makes it a brilliant option for photographers among you who'd love to always have a good camera in your pocket.
