1&1 - Internet & Mobilfunk Reviews 

Poor network coverage. Phones could not register on the 1&1 network.

No internet. No support. Straight up liars.

It was hard to find an ISP that could supply internet where we lived in Hamburg but 1und1 was one of the options.

When we ordered the internet in April 2024 everything sounded good. After 6 months(with no internet yet) but 2 calls with confusing contract changes. 2 Price changes, a change in binding period and at the last call we were promised a price, a router and 1 month termination because we've waited for so long.
It turns out that was just lies.

Now, more than 1 year after there's still no working internet and when support is called they say stuff like:
"I'm not allowed to speak English"
"You are in Germany you should speak German"
"If I went to England and spoke German, people would laugh at me too!"

We get frustrated, especially since English is not our main language either, but if some of that frustration is shared with customer support they just hang up or redirect to someone else who only speaks German.

Currently we are having a lot of trouble trying to cancel and we've probably paid 1und1 around 800 euro, not to mention the mobile bills from calling them (We don't have a german number)

Not sure if it's better for native Germans but at least for us, this has been so much time, money and frustration for NOTHING.
Will strongly suggest not using 1und1 for anything.

Everything went fine but just the customer service guy made me hate this contract because he was acting very aggressively and super impolite and he thought I am stupid because I am a not German and I was asking him simple questions and then he gave him self the allowance to tell me what are my rights in Germany. Two of my friends wanted to do contracts but now not anymore because of this guy. We were even talking German

Honestly, my experience with 1&1 has been awful. The internet is constantly down – super unreliable. And trying to get help from customer service? Forget it. Every time I've called, the people have been incredibly rude and totally unhelpful.

Seriously, I wouldn't wish this terrible service on anyone. Look elsewhere if you actually want working internet and decent support!

I have to come back and give another review. They made several promises to me that they did not keep. (Including, but not limited to saying they will install my internet until a specific date, that they will reply to emails, in English OR German, and that they will cancel my previous contract). Due to their own inability, confirmed by them on the phone, I had my old (more expensive) contract still ongoing. I called several times and they did not seem to care, a very "what are you going to do about it?" vibe. After tons of rude client service I eventually got to a person that "promised" me a partial reimbursement of 10 euros, which is first of all not the amount I lost due to their own negligence, nor does it make up for the stress and time wasted with them on the phone, or for their terrible attitudes. But just another lie nevertheless, the new bill came and the reimbursement did not.
I also want to mention that the lady on the phone, the same one that I complained to had the audacity to try and sell me mobile phone services for 1&1.
As another issue, I had to call and get some technical help from them. They said the person that takes care of this issue is not there and should fix it tomorrow. They said this at 1PM. Nobody was there at 1PM, on a Wednesday for a minor technical problem. The next day nobody did anything so I had to call again. They have fixed it on my second attempt.
NONE of my emails up to this date (even some that are 3 months old, both in English or German were replied to). I am not expecting any reply in this lifetime from them.
Whenever I see the add on youtube that 1&1 is "Immer wieder besser" I vomit in my mouth.

as mother company of GMX I repeat my review here.
I want to upgrade to premium and it does not work. Why? I do not know, there is not even an error message.
So, they want people to upgrade but are too incompetent to provide a working way to do so. Support does not exist. Of course there is no email support only an expensive hotline which as we all know does not mean that competent people work there.
Their app also does not work anymore on iPad, it is known for months and they do not care at all.
Tried to contact them via LinkedIn but even there it is only a dead mailbox.

Terrible support service, monkeys can do a better job in my opinion

Do not use 1&1, they con you on the phone into contracts you don't want and even give you false information, while making the contract on the phone then send you details listed in the contract that were not true. They should be sued, but since they are with Telekom and their doesn't seem to be consumer rights here in Germany, Better use a provider like O2 where they have offices in town and you can read the contract and speak to someone directly. There are nice people on their customer service team, however definitely not all of them that seem nice but are tricking you into a contract you don't want. I have had to pay for service for an iPad for two years, and I don't use an IPad! I am cancelling both my internet and obviously gigabits as a monthly charge for a service that was never used.

I ordered a laptop from 1&1, but the laptop they sent me initially did not have an operating system. I called their customer service, and they asked me to return the laptop. They also sent me a return label, and I sent the laptop back. They then sent me a replacement laptop with the operating system installed.

However, for the past six months, I have been paying for two laptops with two separate contracts. My mistake was that I didn’t check my bank account statements earlier. When I finally noticed the issue, I called 1&1 and explained that they had been charging me for two laptops. They told me they had been working on resolving the issue for the past month.

But today, when I called again, they said the only solution they could offer was to send me another laptop—without even offering an apology. I told them not to send the second laptop, and I am now planning to get a lawyer this week to help me resolve the matter.

I honestly can’t wait to get out of this contract with 1&1.
Ich habe einen Laptop bei 1&1 bestellt, aber der Laptop, den sie mir zuerst geschickt haben, hatte kein Betriebssystem. Ich habe den Kundenservice angerufen, und sie baten mich, den Laptop zurückzuschicken. Sie haben mir auch ein Rücksendeetikett zugeschickt, und ich habe den Laptop zurückgeschickt. Anschließend haben sie mir einen Ersatz-Laptop mit installiertem Betriebssystem geschickt.

Allerdings bezahle ich seit sechs Monaten für zwei Laptops mit zwei separaten Verträgen. Mein Fehler war, dass ich meine Kontoauszüge nicht früher kontrolliert habe. Als ich das schließlich bemerkt habe, habe ich 1&1 angerufen und erklärt, dass sie mir für zwei Laptops Geld abbuchen. Sie sagten mir, dass sie seit einem Monat daran arbeiten, das Problem zu lösen.

Aber als ich heute wieder angerufen habe, sagten sie, die einzige Lösung sei, mir einen weiteren Laptop zu schicken – ohne sich überhaupt zu entschuldigen. Ich habe ihnen gesagt, dass sie mir keinen weiteren Laptop schicken sollen, und ich plane jetzt, mir diese Woche einen Anwalt zu nehmen, um die Angelegenheit zu klären.

Ich kann es ehrlich gesagt kaum erwarten, aus diesem Vertrag mit 1&1 rauszukommen.

Awful internet. Always slow and can't provide internet far often than expected. Total garbage.

This company is crap, they will try to rip you off every cent you have, their customer support is very passive and not very helpful. I would not recommend this company to anyone, please find another one

I traveled outside of Europe and, upon arrival, did not receive any message about roaming rates or Internet costs. After connecting to the airport Wi-Fi, 5 minutes after turning on my phone, I received three messages simultaneously: one about the rates, one indicating that 80% of the limit was already consumed, and one about the block after reaching €70. All of this happened without any prior warning, leading to a charge of €70 in just a few minutes.

I find it unacceptable that the notifications arrived late, causing data usage without first informing about the costs. I contacted customer service, but they blamed me for not checking the rates beforehand and did not offer any refund, not even partially. This seems to be a clear malfunction of the service, and I am extremely dissatisfied with how the issue was handled.

When I had finished paying for my mobile phone they continued to take the monthly payments. When I noticed the error I asked them to repay the money they refused saying it was not their mistake. They literally stole money from me. Do not go with them =, their customer service is jaw droppingly bad.

Is a Zero Star possible? This problem is continuing for 2.5 months. Mobile Phone contract came to an end, and I asked for a renewal for the cheapest plan. There was an offer for Euro 9,99. BUT!!! Instead of changing my contract to a new plan, they kept my old plan added many upgrades to my old plan, and the monthly fee comes to Euro 78 per month. That is not the worst, they ordered me a new plan, gave me the Euro 9,99 monthly fee. BUT they put a surcharge of Euro 39,99 fee on my new plan. The worst of it all is that I can not cancel my old plan anymore, because they put it in a 2 years contract. And I can not transfer my old number to the new plan. The Worst!!!! And they refuse to fixed it. !!!! I told them there is no logic for me to have 2 plans. I didn't order 2 plans.
They said that is my problem!!!

One of the worst internet service providers in Germany. Don’t get caught in their trap signing the contract. When they want something from you, they’ll constantly hassle you. But when you need their help, they’re nowhere to be found.

Rating: 1/10
Recommendation: Stay away.

I wish I can give zero stars; I was using this service for almost 3+ years. I had experience issue with my device, and I reached they offer me a replacement, later I came to know they cancel my current contract, and it is a new contract, and I need to pay 295 euro for it a plenty. I said sorry I am returning your new device, just repair my device which is under warranty they said as far as you return you will be not charged and on return back, I was still charged, I reached for refund they refund 9.90 euro. And reaching the said it was a typing mistake we will refund it. It took 1 month for refund, and my device went for repair, it took 2 weeks, and it was not repaired, I had the same issue, upon reaching for third repair because I had one repair at the start of my contract. I got told they will contact me. I waited two weeks and called again. they told me they have issue internally and just disconnect the call without telling what to do. Now upon calling again, I came to know their internal system shows my phone is still in repairing, which means my device was never repair. If it was repaired, the question is there why it is not update in their system, there can be a mistake once or twice but, in my case, it seems I was mistaken to choose their service. I have written many emails and called almost more than 100 times. I have only one thing to do now because in 6 months my problem is not solved, go legally with them.

STAY AWAY FORM IT!!! WORST PHONE COMPANY EVER! When you sign the contract the promise you everything, inform that you can cancel at any time, that the service will be great. What you get is a low speed internet (30mb tops instead of "100mb minimum guaranteed"), and when you try to cancel it, basically you understand you got scammed. I sincerely feel bad for the good people working for this company. Despite being nice and friendly, they even explain to you that reality is very different than it was promised to you and after quite some time, they just hang-up on you.
I have requested to cancel my contract on November 2nd, and called you on the same day to confirm the cancellation. Then in December you charged my account again (an absurd), and gave the lame excuse that it was regarding a notice period. In January, to my surprise, I receive another invoice. After calling them again, the agent says "he is sorry", says he will check, and hang-up the call. What an experience!

Horrible they made me pay 150 euro for data roaming that I did not switch on and then another 85 euro in another month for the same problem although they guaranteed that they switched my roaming off!! Also you can never reach them via email which is so difficult if you are travelling and cant use your german number!

I can't describe how angry I am im waiting for an iPhone and AirPods that I bought at the release date of the iPhone 16 and TO THIS DAY 1&1 can't tell me anything about it in my e mail they say its on the way but WTFFF is this AliExpress or is this a German company how bad can a company be
this is and edit I now just bought it on Congstar FūCK 1&1

I think this company is a scam. When you try to check if fiberglass is available at your home, it says "yes" but they can only provide max. 250 Mbs DSL. They say: it's Glasfaser-DSL-Anschluss which is so confusing and many people fall victim to this. Unfortunately fiberglass is NOT yet available in our street.
