o2 Deutschland Reviews

I had a contract for me and my wife for more than 3 years.

At some point, I got an offer by phone from O2 service personnel.

They knew I'm a customer and they offered me a new contract because it will be cheaper than my existing one.

So I signed it. Then I realised that they didn't cancel my previous contract. I realised it after 14 days. Now they refuse me to cancel one of the contracts.

I need to pay for 4 numbers for the full next year now.

THIS IS THE SCAM, literally.

I close all the relations with them once the contracts are ended.... Never O2 again!

Worst Customer Service!

I’ve never encountered such poor customer treatment. I cannot recommend O2 as a provider to anyone.

I had a two-year contract for a SIM card, but when my phone broke, I asked to update my contract and include a new mobile phone. To my surprise, they told me I’d need to sign a separate contract for the phone! How does it make sense to pay for two separate contracts with the same provider?

O2 seems only interested in taking your money. There’s no proper consultation or support. What’s even more disappointing is that they seem to take advantage of newcomers.

Save yourself the trouble—stay far away from O2!

Terrible service, today I finally decided that O2 is not good at all. The stupid site where you have to extend your contract doesn't work, it's refreshing all the time and the live chat and customer supports of any kind doesn't work (says System fehler).
Also their offers are scam, better buy some devices on other places because it's cheaper 200-300 hunder euros.

2 years ago, without my knowledge, they connected me to a paid service related to games, which I had never even heard of or agreed to. I accidentally noticed it in the account details. After I complained, they agreed to refund my money only for six months.

One of the worst experiences I had was with this stupid service. They call you saying that they have better offers for you because you were their long term customer and said that I can import my old number and keep using it and now after many calls they did not import my number and kept saying it will be done soon but nothing worked, they did not do anything and now they are saying that I need to have 2 sim contracts which I don’t need. Making the new contract was done in 5 minutes via a phone call but to cancel it we need to make so many calls to their customer service and Everytime a new employee comes up with a new rule and we were still unsuccessful in cancelling the contract which they kept it till 2026 without my consent. They just want to tire you out and manipulate you into using their services but wont cancel your contract. Even 2 weeks ago we called and employee said that the contract has been cancelled auccesfully but when we called them last week they said it was not cancelled. This is beyond stealing innocent people money.

They are the worst and beware of them , never sign a contract with them because you will never be able to get out of it.

I have been their customer now for a few years. I first got their mobile contract, which relatively soon proved to be a mistake; there are often situations where I don't have any signal, and I am in a big city somewhere in NRW. Too often.
Internet is expensive, although reliable; still, often it happens there are some interruptions in the connection. You can't control your contract online, but rather you have to call in, so they can try and sell you additional services.
Customer service is epically bad, if you don't call nothing will be resolved.

The worst company I ever had to deal with. The customer service is inexistant. The network quality is really bad. I wouldn't recommend this company. Definitely the worst internet provider of Germany.

I'm trying to cancel my contract because of the quality of the network 5G very bad and totally not useable. I sent email, letter, call many times, WhatsApp message but the only thing they're doing is intimidating me with lawyer papers to claim the payments for an inexistant service.

O2 is a joke of a company! At least in Germany! I have never experienced such bad internet in my life…Every other day it’s down and not working…when it’s working, it’s slow as a snail…you can’t even have a proper iphone software download without the internet constantly crashing! It’s 2024!! wake up O2 or make room for others!!!

It is a scam, run away, never get a contract or you will regret it when you decide to cancel the subscription. I left Germany and the agent explained me how to return the rooter, scanning the QR code and then sending it via dhl. I did exactly as they said, following their protocol. I am outside Germany and they say they never received the rooter from DHL. I have the receipt from dhl still. Every month they send me different bill for it. When we speak and explain the situation they say they will open a ticket. I have probably had 100 calls with their customer support. Every agent say the exact opposite thing. One said your account is closed, but why they keep billing me every month. Apparently i am hiring a layer and will fight o2. They are very sneaky and will do their best to charge you as much as possible.i never in my life had a worse experience with other operator and i lived in 8 countries. Never ever get anything beside prepaid with this scammers

I visited O2 kiosk in MediaMarkt Hamburg today (October 21st) to resolve an issue with my O2 contract. Unfortunately, my experience was deeply disappointing due to the unprofessional behavior of a staff member at the O2 kiosk. From the moment I started explaining my situation, she seemed disinterested and cut me off mid-sentence, displaying no patience or customer service skills.

When I tried to clarify my issue, she responded in a dismissive and sarcastic manner, which felt extremely disrespectful. I was there to inquire a payment for my contract, which had previously been rejected by my bank on October 10th, but her attitude made the situation much worse. When I asked for the address, she didn’t even take the time to spell it out, just pointing vaguely and leaving me confused.

I mentioned that she could be more friendly, to which she responded that she was trying to be friendly—this didn’t reflect at all in her actions. Her behavior was incredibly unprofessional, and I left the store feeling hurt and frustrated.

It’s shocking that O2 continues to employ staff who treat customers with such disregard. This was a terrible experience, and I’m extremely disappointed in how this was handled.

I am new in Germany and thought O2 would be a good choice for mobile contract. But I am very disappointed.

First, the reception is really bad. I live in a city but often have no signal or very weak network. In Poland, I never had such problems.

Second, the prices are very high. I pay much more than in Poland and get worse service. This makes me really angry.

Third, the customer service is very bad. I had problem with my bill and had to wait long time until someone on phone could help me. The staff was also not friendly or helpful.

I regret very much that I cancelled my old contract in Poland. It was much better and cheaper there. I cannot recommend O2 in Germany.

really ripping off company policies, charging hidden costs for replacing broken from old router. on the hotline the person was offering the exchange without extra costs, after sending the router they sent me invoice for 100 Euros apparently for shipping and connecting the device to the network (what I did myself on the O2 app).
I can't believe that in European Union such a fraud company has rights to exist.
Customer service on the calls didn't offer any solution. Returning old router didn't bring anything so far.
Customer service replying here, didn't take any actions to help me or try to solve the issue. Just write some polite f u c k o f f reply....

Dear o2,

I want to inform you that I’ve had the worst experience with your English support in Germany.

A few minutes ago, I called the English support line you provided, and the representative was disrespectful and offered no assistance. To make matters worse, he ended the call abruptly without resolving anything.

Thank you for that, and shame on you for such poor service.

prepaid sim card doesnt work at all. You can not gothrough identifiation process either online or offline and calling to customer service is just useless as they ask to do identification everytime (which has been done more than 10 times) Stupid card with Stupid service.

Dont know about postpaid but STAY AWAY FROM PRE PAID CARDS

I am extremely disappointed with o2.de's handling of contract cancellations. I specifically chose a monthly contract and paid extra for the flexibility to cancel it easily, but the reality is far from simple. Despite their promises, the process is riddled with unnecessary roadblocks designed to frustrate customers and keep them paying.

Firstly, they refuse to cancel contracts in-store, forcing you to rely on their online system. However, the online cancellation process is intentionally complicated. Even if you submit the form correctly, they seem to find minor, arbitrary issues to reject your request, ensuring they can continue charging you. To make matters worse, they only send critical updates via SMS instead of email, which can easily be missed, especially if you're using a data-only plan in a modem. It feels like they deliberately choose the least reliable method of communication to create more hurdles.

If you're looking for flexibility and transparency, I strongly advise you to avoid o2.de. Their practices are misleading, untrustworthy, and exploitative. I deeply regret signing up with them—save yourself the headache and choose another provider!

Worst company for a mobile plan I've ever dealt with. Worst coverage, reception, and app. Trying to sort out different plans was a nightmare. Even getting SEPA to finally work was awful. Worst English support.

Everything does not work. Internet is not usable for videocalls sometimes even for voice calls. After almost 2 years I was not able to login into the app or through browser to see my contract details, because I need some number for it, which however can be get only once you are logged in. That is why cancelation is also pain in the ass.

Hey Guys,
thinking about my experience with O2 is ambivalent. Sure the price is good, if they would stood up to the fare details, i would be totally happy. But the sad truth is, they are selling products wich don't hold up in reality. But the worst thing is, there is no service per E-Mail. You have to call them, so they can make money out of there false promises. Btw. the support doesn't help in anyway it's just to scam people.

So guys, be aware O2 is a scam company.
