How to switch T-Mobile (Germany) voicemail to English?

I decided to write here the step-by-step instructions because couple of times I needed it and forgot the exact combination.

My previous mobile operators I had (Orange Romania, Vodafone Czech Republic, ….) offer a better support for the English speakers. When you call the most common services (voicemail, customer service help) you have the option to chose the English language from the begging of the call – the “For English press 2″ (robot voice).
Well, if you are a T-Mobile (Germany) customer and is your first time when you call the common service numbers … kein Englisch :) . This step-by-step is definitely good for the foreigners, or tourists whom for various reasons will use a T-Mobile SIM card.

Step by step.
1. Call 3311 (this is the voice mail number) and wait until the German announcement stops.
2. Press 3 and wait to finish to mention all the options (still talking to you in German).
3. Press 4 and wait to finish to mention all the options (still talking to you in German).
4. Press 1 and wait to finish to mention all the options (still talking to you in German).
5. Press * (star).

Done!
