1&1 - Internet & Mobilfunk Reviews 

I don't have a good experience with this company.

For example recently a mysterious charge was on my bill, there were however no details. They have an option in their service center to access more details but it was 'conveniently' broken. Contacting their customer service was also problematic.

I can not recommend this company or their services.

Customer Service has been amazing! I am leaving Vodafone and I have seen how poorly they treat their customers. 1und1 has been very professional and proactive in communication and offered much help with different solutions for me to get my home internet working again. Especially the Man that is helping me with this order. I do not know his name but he has gone above and beyond what I expect as a customer. He speaks English very well and he has called me back after the connection was dropped. he also has checked into the Max speed for me and he has been very professional and very efficient as well as being very polite to me.

Avoid at all costs.

Not's not worth the money you "save" as there packages are a scam. Go with a real provider.

They don't offer just internet. They throw a bunch of addons at 0€ and raise the base price. I don't see how this is legal in Germany. Now I have a "package" that I can't change it since it's locked in 24 months with items that I don't need.

Do better Germany. Regulate this nonsense into the ground.

Also, their customer service is useless which is to be expected.

I've been with them for my Wifi since 2018. Suddenly since the beginning of the year I have constant problems - the internet reliably DOESN'T WORK almost every day between 7-12pm. I contacted them multiple times to no avail, when they call me back, is at awkward times when I am at work and can't pick up. The one time I managed to speak to a technician, he told me nothing is wrong and if I don't like it, I should use a cable, then he hung up. Unacceptable.
Currently the internet has been working for about a week with no disconnection issues, however, is so slow that I can't open anything. Even Whatsapp messages are taking time to send. I am at the end of my rope here and will probably have to cancel the contract (if they allow me lol) because all this has resulted in very high mobile internet bills, as I need internet to work.

So yea... 4 years no issues, 1 year absolutely appalling service.

UPDATE:
it’s now 3 months later and it’s gotten even worse. I’m
Lucky if I have connection for 3-4hrs a day. This company is a pile of garbage.

I'm waiting for 3 months already and still no date of connection

Helpful, careful, and clear communication

Very quick process and friendly customer care person. I just hope the connection time is not too long.

I closed a dsl contract with 1&1. First they messed up with adding Sofort Start to my package and when i called them informed me that it cannot be added anymore(cannot correct an error on their part). Then when I used my cancellation right. Every single time they managed to get it wrong and didn’t cancel my contract proper. Their call centre advised me not to take the router package to ensure that i dont need to send it back. Now they still failed to cancel my contract and keep harassing me.

I moved and applied for a relocation service. A month has passed, and they have not arrived. I eventually cancelled the request.
I applied for a cancellation over a month ago, but they won't cancel my mobile contract. They claim the contract has been extended, but I don't remember signing an extension. That aside, even if the contract is extended, all contracts must have a trial period. They claim there's no such thing and I have to tolerate their perfect service for another two years. ;) On top of that, when I was asking their CS via chat if there is a trial period, they gave some irrelevant answer and ended the chat abruptly. I cannot say I am surprised by this unprofessional move. They have been so unprofessional that I believe any bad thing anyone ever says about them.
I am pretty sure they have fully earned all the bad reviews here. Do not risk your money, your time, your mood on them. They do not deserve it.

My International collegues be aware of this Company and their offers as they are mostly scams.
Besides i would like to talk about my experience with them i ordered DSL connection and it did'nt work out and they charged me huge fees and months of subscription without being able to use it, and refused to give reimbursement.
Again be careful especially with ordering on the phone or online, instead i would suggest that you go directly to a shop and understand and try to read the contract before signing and if possible bring a german friend with you.

Getting forwarded multiple times with no resolvement on my issues with the DSL-installation order. Now they want 60 euros for overbooking fees for a router that should've been free for waiting for the DSL installation. I wanted to recommend the company to my friends, but not anymore. Absolute foolish customer service.

bad to no english support, overcomplicated system. password set up doesn't work, trying to reset it by e-mail and then following the link saying that I need to add a phone number and call them for that... writing to chat support, you're met by a rude person who talks like they're annoyed by you making them do their job and asking politely for help. Literally chat customer support employees are useless and refuse to help.

I recommend completely avoiding this company.... I will also look into the matter if there is a consumer protection service in Germany as the company shouldn't be treating customers like this, especially if they want the money.
1/5 score for experience

I have been using the internet for 2 years. I signed a new contract because the old modem was not working. I had to get a new one - for 5€ per month !!! I moved into a new apartment, I also told the address. Everything was fine, the internet was working... Until the 3rd week, then it stopped. We spoke 13 times with the operator of 1&1, each time they told us that everything is fine and that the Internet will come in 2-3 hours. It never came... We talked to a technician and he told us that they would have to visit us on site, there is a problem. I explained that I work online and I need internet and I suffer monetary losses!!! But they gave an appointment in 2 weeks.... absolutely frivolous for such a big company!

Technician never arrived. We had an appointment but he made a fake excuse. Now, I have to wait another month to have Internet installed. I simply cancelled the contract. Germany is not a serious country in regards of trains, Internet, banks/payment methods and supermarkets.

What a pleasure to talk with somebody who is really interested in selling the product that fits my needs and answer all my questions being knowledgeable. Really 100 percent satisfied
