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.

Nokia Lumia 820
The Nokia Lumia 820 is also not yet released, but again is expected to come out after the launch of Windows Phone 8 on 29 October, probably alongside the switch-on for EE's 4G network on 30 October.
As a guide to its probable price, the Lumia 820 is expected to be £395 SIM-free.
The Lumia 820 is almost exactly the same as the flagship 920 device, except for a smaller display (4.3-inches compared to 4.5 inches) and a slightly smaller battery.

LG Optimus True HD P936
EE is also offering plans for people who don't need to buy a phone along with service. These contracts, which come with unlimited minutes and texts, have tariffs based on the amount of bundled data.
For 500MB, the cost is £21 a month, while 1GB is £26, 3GB is £31 and 5GB is £36. No 8GB is listed for SIM-free plans.
A handful of 4G-ready phones are available in the UK, such as the LG Optimus True HD P936 shown here. However, any smartphone needs to be compatible with EE's 4G network.
"By compatible, we mean it's a 4G phone that you've bought either directly from Orange or T-Mobile. Or on those networks through an indirect retailer," EE says on its website.
This caveat doesn't apply to the iPhone 5, if bought from Apple, Carphone Warehouse or Phones4U.
EE is also trying to woo existing T-Mobile or Orange customers to its 4G services. If they recently bought a non-4G versions of the handsets, the operator will let them swap it via a £99 upgrade.
