A free app for Android, by Telefónica Germany GmbH Co. OHG.

Mein Blau is the app for all your mobile needs. This is your home for all the data, minutes, and SMS services you use on a daily basis. Mein Blau combines all these services in a single app. This way, you can keep track of how much data, minutes, and SMS you have already used.

In addition, Mein Blau allows you to access all your account information at any time. This means you can view how much data, minutes, and SMS you have left, how much you have used in the past month, and how much you have used in the past year. You can also check the status of your data, minutes, and SMS services.

The Mein Blau app is the perfect tool to keep track of your mobile services.
