Motorola Moto G (4G LTE)
Although the Motorola Moto G with 4G LTE is a bit pricier than its 3G-only sibling, it still has one of the best displays in the budget arena, its processor makes operation enjoyably smooth and its rounded, compact body is both comfortable and attractive. If you're after an affordable all-round entrance into the high speeds of 4G, you've come to the right place.
If ultra-fast data speeds are of the utmost importance to you, but you don't really care about having the biggest, brightest screen or fastest processor, the EE Kestrel is worth checking out. It won't impress anyone with its specs and the bundled software is annoying, but it's the cheapest way to get on 4G.
Samsung Galaxy Alpha
If you love the high-end tech Samsung crams into its phones but hate the plastic bodies, the Galaxy Alpha may well be the phone for you. Its processor and camera perform brilliantly, while its compact 4.7-inch size makes it very comfortable to hold and use in one hand. Its low-resolution display is a big letdown, though, especially when you consider the high price of the phone, which does take the shine off an otherwise brilliant phone.
Nokia Lumia 635
With its fun design and cheap price, the Lumia 635 is a decent option to consider if you're after 4G LTE on a budget. It's only marginally more expensive than its near-identical 3G-only Lumia 630 sibling, so you should certainly opt for the 635. If you want a better selection of apps however, the Motorola Moto G is still the 4G phone to go for.
