ALDI TALK is the popular supermarket's app for its own cellphone provider network. Now you can keep up with all of your phone bills in one easy interface by installing the official ALDI TALK app. Plus, you can top up your phone with credit, buy more data, and much more. That said, even though ALDI is a widespread supermarket found all over Europe, this app only really works if you're in Germany and are already on the ALDI TALK network.
