1&1 - Internet & Mobilfunk Reviews 

I had a couple of tries with 1&1 Customer service and eventually with the English-speaking person, Mr. Kluge, who was very helpful and knowledgeable, I manage to change my current tariff from 100Mbit/sec to 250Mbit/sec in anticipation of Fiber optic technology.
I was so far with various Internet service providers in Germany, but in my experience only 1&1 has a steady quality and improvement of Internet services (DSL and Mobile phones), which is also cost-effective (kostengünstig).

Unstable connection
50€ per month, for having internet troubles everyday, shutting down your work or any activities you were currently doing, without any explanation.
Their agents, to settle your internet connection, are not able to make it properly, and their only agents are not able to make it as well.
I do not recommend.

I gave 4 stars for the ladies, doing a wonderful job at 1und1 customer service.... it has always been strange attitude with most men at 1&1 ... they hardly help or solve my complains or make me understand briefly what happening regarding my oder.... I always get better support from the ladies

Impossible to contact in English

On 04.10.2023 I placed an order with a new iPhone 15 pro max. I have then noticed that I mistakenly placed 2 orders in a row. I called the help center via 07219600 but no one in the team answered my questions, also they hanged up after recognizing the English language. They just say "Hallo and Tschüss". They never want to help, however when you try to place a new order everyone was very nice and helpful.
I now want to cancel my second order which I do not need it. I also sent email and filled out the contact form as well but still no response in 2 days. However, when you place an order they immediately response via email. I believe there is big issue over here. Even if you try to contact in English, they just hang up instead of transfer the call to a English speaker. I experienced this 3 times today. I hope someone reads and help instead of talking nonsense. Worst customer service I have seen so far.

Informative, fast, and friendly

Worst Internet service provider. Customer care is zero. If some one try whole day then may be one time , Technical team will pick up phone. Rude behaviour, do not care about talking in polite way, even some time cuatomer service people say racist comments like if you want quick service then try to speak in German

I have cancelled the contract before the automatic renewal. I called and confirmed. By the way if you don't then it's not cancelled. That's all about making it easy. They were still charging me even though contract was cancelled. When I called, they transferred me 5 times, because no one wanted to deal with this. The last lady however was the best. She activated my contract again, so they can officially charge me for it. I have no other option but to think that was out of spite, because I dared to bother them. I received an email to confirm my order, I did not, I actually specifically sent an email saying I do not want this. It didn't stop them. So I cancelled it again. They paid me back for that one month. And the whole contract disappeared from my 1und1 app. Before it disappeared I could see the start date was when they activated it instead of 2 years earlier and the cancellation as well was after their activation not when I cancelled it. I sent about 15 emails regarding this matter. At this point of time I'm just being ignored. Maybe they done it so wrong no one in the entire billing department know what's happening.
Company is a joke. I can't belive is allowed to condone any business , while charging me unlawfully. If I haven't paid my bill they would destroy my shufa score and block my account. Why is the accountability only one way with 1und1? I can't wait when my other contracts will finish and I don't want hear of 1und1 ever again. On top of that the worst signal ever. Absolutely do not recommend and please do not think for a second that my experience is the only one. There is plenty of people out there whith similar issues but not all people bother to complain or do something about it.

They have the worst customer service ever.

I can't say if this is a recurring practice, but in my case it has been extremely difficult and stressful, inefficient and ineffective to contact 1und1 support. It all started when 1und1 discontinued my internet plan. 1und1 sent me an email informing me of the price increase and gave me two options: I continue to use the service and pay more or I cancel the service.
As a bonus to continue, 1un1 offered me an increase in connection speed, but for that I would need to get in touch with 1und1. At this point, everything got very difficult.
I don't speak German and all phone support from 1und1 is in German only. I couldn't find a channel via phone to speak in English. The only available channel I could find was via facebook. But it is very difficult to get a satisfactory response from 1und1 via this channel. I have already explained the fact at least 5 times and there is always some new obstacle to the upgrade.
Well, at least in my case, in my experience, 1und1's support left a lot to be desired.

These people are deeply incompetent. They royally screwed up our order and left us hanging between two contracts for weeks without contacting us. When we were overcharged they did nothing to correct. Honestly, save yourself hours on the phone and go somewhere else.

Worst customer service you can experience. They can speak English when they are selling their products, but as soon as there is a problem than they only speak German. I called them today and asked politly if we can have the conversation in English, he told me (We live in germany and we must speak german). What kind of racist BS is this?

This company's technical support is a total joke. if ever you need one, just fix it yourself, you will save lots of time.

It's the typical IKEA internet German company as the others.
I've just subscribed (or let's said they pushed for that).
And they get my private German mobile phone which I've never activated. And I never provided to them.
Please be aware how can get so easy all your personal information without asking you.
If are lucky as me a non German speaker. Be prepared to be mistreated. They won't to work. Lazy people. They cut off calls.
And please never ever have a "technical problem". You will be ages waiting for assistance and never solved because I'm don't speak German.
It's been a month I'm going around to get the connection and yet not internet.

so bad experience! they are stealing from me from more than a year and i can not do anything!
i have a contarct that i can not cancel and they take every month 25 euros for a service that costs not more than 10!!
and by law they can still take my money for another year!!!! they are thiefs!!

*edited - 4 stars
Due to a forthcoming customer service, allowing me to exit to the date of (price) change and an uncomplicated handling of hardware return, I change my review from 1 to 4 stars.

*original - 2 stars
T&C's (DSL) changed in May 2023 for dismissal for exceptional reasons. Now the client is only allowed to cancel on a 3-month notice instead of to the date of change. Surprisingly, after this adaption, price increase notifications to 1&1 customers are piling up (browse the www), not allowing clients to cancel immediately (to the date of price raise) anymore. Surely not a coincidence. Hoping now, that §626 of the German Civil Code (BGB) overrules this tacky manoeuvre of 1&1.
