Very friendly staff! They speak fluently at least 3 languages there, so you have no problems if you don't speak German, which is my case. I got to the store cause I had some questions regarding the internet plan I had hired over the phone, and they even helped me with things not related to my internet service. So far, this is the best customer service experience I had in Germany, BY FAR! Strongly recommended! 10/10

  Excellent support and service! Very friendly staff, who are genuinely want to help and find the better solution for you, withing their possibilities. Really recommend it!

  Alex was very helpful and friendly. We moved in Berlin a few days ago and came to apply for mobile and home internet contracts. It went smooth. We are very satisfied with the service here.

  The store owner provides English, Russian and German service. He always greets us with warm hearty smile and the small sweet candies in the counter. When we just arrived, he introduced us Shell electricity provider and Barmer health insurance, which helped us get on track of the new life in Berlin. If you are also fresh off the boat, check yourself in here?

  This is by far one of the BEST customer service experiences I have had in Berlin. As a non German speaker I truly appreciated the service of the team here who ensured that everything regarding my internet connection from the signing of the contract to the day I was actually connected was explained thoroughly to me in English. Kudos once again!

  The service offered is great. They really take care of the client and help also by language-barriers problems. Everything is explained in English as well and if you need any help also in doing the silliest thing (paying the first monthly bill), they help you. Thank you!

  Great service in multiple languages. Helped me solve a problem quickly when no other company involved seem to care. Thank you 🙂

  I HIGHLY recommend this store. I was at my wits end attempting to deal with pre-paid SIM-card number transferrals and three phone companies simultaneously. With ease, with great calm and knowledge, the lovely couple at this store solved my telephone dilemmas (and saved the day!). Get your contracts (and all things mobile) here. Definitely.

  Alex has helped me now twice since arriving to Berlin from the US with my cell phone and home wifi internet. Both times he fully explained to me what my options were in a clear way and provided great customer service. It has been lifesaving knowing that someone can help me set up these important services in a way I can understand. I will gladly give my future business to 1&1 no doubt. The store location is also very convenient right by public transportation.
