You need to have signed up on the T-Mobile website ( Increase Your Mobile Network Coverage with T-Mobile & Orange )
After that you will automatically roam onto Orange's (2G only) network when there's no T-Mobile signal. Works reasonably well, does occasionally take a little while to switch back.
By default on Android 'Data Roaming' (Settings --> Wireless and network --> Mobile networks) is turned off to avoid you running up a huge bill abroad. If you turn this on you'll be able to use Orange's 2G data network as well (GPRS and the slightly faster EDGE).
If you have data roaming off then you'll be able to call/text when you roam to orange however you won't have any internet connectivity at all.
If you turn data roaming on, you'll be able to access the internet over orange (albeit fairly slowly). There will be no charge for that assuming you already have data/internet included in your T-Mobile package. Just remember if you take your phone abroad to turn it back off!
There are some useful FAQs on the T-Mobile site about some of this that make it very clear you won't be billed anything extra for the roaming.
How is 3G on T mobile anyway, never been with them?
Meh - it's not the best. Where there's signal it's quite speedy/stable but they do seem a step behind everyone else with coverage. Probably why T-Mobile service seems to be a bit cheaper than O2/Voda.
Still, I'm hoping as the merger with Orange progresses it will improve.
