HTC One XL
Like the other 4G-capable phones carried by EE, the HTC One XL costs from £30 on the high-data 8GB/£56 a month plan.
On the lower-end 500MB/£36 subscription, the handset is £150 - equivalent to the Galaxy S III LTE and cheaper than the others so far.
The One XL handset runs the Ice Cream Sandwich version of Android. It comes with 16GB of internal storage and a 4.7-inch display. However, the display's resolution is 540x960 pixels, much lower than the corresponding non-4G One X's 720x1,280 display.
Hardware-wise, there is a 1.5GHz dual-core processor and 1GB RAM.
Huawei Ascend P1 LTE
The Huawei Ascend P1 LTE is free on contracts with more than 1GB of data (starting at £41 per month) or £20 on a 500MB/£36 contract. That's more than £100 cheaper than its counterparts.
It has a dual-core 1.5GHz TI OMAP 4 CPU, Android 4.0 Ice Cream Sandwich and a 4.3-inch Super-AMOLED Corning Gorilla Glass display.
Nokia Lumia 920
The Nokia Lumia 920 has not yet launched in the UK, so EE has not revealed its price plans for the Windows Phone 8-based handset.
However, the smartphone is expected to go on general sale at approximately £475, SIM-free. By comparison, a 16GB iPhone 5 is £529.
The phone has a 4.5-inch TrueBlack display and dual-core Qualcomm S4 Snapdragon processor, which Nokia claims is up to 30 percent more efficient than quad-core alternatives.
