if you have a contract at Eplus (the carrier that is underlying Aldi Talk as well) you can now book the so called "travel flat" option - 3 Euro/month in addition to your normal fees extend the validity of unlimited calls & data also while roaming within EU, norway, switzerland and liechtenstein...
Valid in all BASE All-IN tariffs for the moment.
