I bought the unlimited data line. the Internet speed is as slow as 3MB for download and 0.7 MB upload for me in the centre of Berlin Alexanderplatz. I spoke to customer service several time that couldn't help because they see everything is fine from their towers. I was able to get to the complaints department that told me that I can't get out of my contract for 2 years and there's nothing they can do. watch out not to get scammed!

It's a good app that takes you through the steps of installation. However, if you set it up in English, and you reach the stage where you need to give the MAC address, it still tells you to call the German language service making the job difficult. O2 also has an English service number. If the user is set to English, the number to call should also direct to the English service number.
