The staff was really friendly, and helpful and solved my query very quickly. But, the service of 1&1 itself is worse. I am suffering from their mess since last 2 months.

  Finally I was able to get a new phone number, and also the energy provider and a home internet. The service was fast and very friendly. If you one of those people that just moved in to Berlin and can't handle if those new internet, phone, energy provider - this is the place you were looking for =D

  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.

  Alexander helped me so much, really nice guy, really amazing service.

  The sir here is really nice, he helped me to solve my problem very quick and explain it to me. It's a good choice to order your internet!

  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.

  1&1 is the best internet provider in Berlin. Their client support is just perfect. They really care about their customer.

  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 staff of the shop was really friendly, and helpful and solved my query very quickly. However, the service of 1&1 company itself is worse. I suffered from their mess for 2 months.
