UK carrier EE (Everything Everywhere) has already begun to migrate existing customers with Orange and T-Mobile UK across to the new brand. Those who own Windows Phones and make use of said networks will see "EE" on the phone Live Tile once the switch has been carried out. The company is also in the process of launching the UK's first 4G LTE network on October 30th.
Taking on the mammoth task of moving both Orange and T-Mobile under the single brand (while forming three separate carriers), as well as firing up LTE, EE is certainly one of the major players in the mobile industry for consumers who reside within the UK. While customers will be seeing a change in branding on mobile devices, their contracts with both Orange and T-Mobile will remain. It's more aesthetics than anything that will affect service provided.
Should those who are on 3G plans with either network wish to upgrade to EE's new LTE solution, we've been previously told it's a simple contract alteration to take advantage of another 'G'. As for customers who are set on remaining where they are, EE branding will still appear on a connected mobile device with a SIM inserted.
During the ongoing transition phase, should customers on either network experience issues with services (be it web browsing, MMS, etc.), contacting customer services for new network settings is said to rectify the problem.
Orange and T-Mobile are promoting EE's new 4G capabilities with new hardware on multiple platforms to boot. Both the Lumia 920 and Lumia 820 will be made available soon after LTE is launched (and when everyone on the Windows Phone platform is ready to start shipping).
It's worth noting that EE plans to cover the following cities with LTE by the end of 2012: London, Birmingham, Cardiff, Bristol, Edinburgh, Belfast, Leeds, Sheffield, Manchester, Liverpool, Glasgow, Newcastle, Southampton, Hull, Nottingham, and Derby.
Thanks, Richard, for the heads up!
