I tried many times, but it was a no-go.

The roaming is switched off from area to area starting last year already. By the end of this year it will be completely disabled. While o2 is still building a lot of GSM stations these days there will be for sure areas without coverage with o2 (at least temporarely) towards the end of 2009.
