While searching to see if there was any information about EE's future 4G rollouts (I'm waiting for Warwick & Leamington Spa to go live), I came across this article instead. It says you need to have data roaming enabled to take advantage of using both Orange's & T Mobile's masts for 3G and was wondering if anyone knows how accurate that is.

I ask because before the EE rebranding I never had roaming enabled before and I would see "Orange T-Mobile 3G" instead of just "Orange 3G" every now and then. So basically the article has confused me but I now know I am not alone in noticing I don't get as good coverage as I used it.

Also if anyone knows where they'll launch 4G next that'd be appreciated too.

It was needed in the early days before the "smart signal sharing", but today it shouldn't be needed.

There was a thought the software on the iPhone 5 at the time of that article (before iOS 7) had some glitches and wasn't properly switching between the two legacy networks behind the EE name. These reports went after iOS 7 launched.

In many areas you will find Orange and T-Mobile network codes still transmitted (234-33 and 234-30) as some handsets, tablets, and 3G/WiFi devices show two EE 2G, and two EE 3G networks received. iOS devices don't.

In time I believe the duplication of network codes will go, but probably a long time off yet.

It shouldn't be needed but some weird phones might benefit from it. Can't think of a single one though. All modern phones should obey the standards correctly and see both networks as "home" and not need roaming.
