Thanks for your comment: But it's clear when you use a SIM card in roaming for data, you need to enable data roaming. Sometimes it won't connect to the roaming network as you have pre-selected the home network. Then switch to automatic selection, if you don't know on which network your SIM is roaming. But what T-Mobile is concerned, it's clear that they are on Telekom in Germany as it's the same company. The reason why we state all APNs for every provider here is exactly this: sometimes they need to be adjusted manually and they may be hard to find.

So you've done everything right and that's we are doing this stuff here.
