klarmobil.de Reviews 

This is the worst service provider of all time. I say you, never choose them. I am cancelling my contract from 3 months which i never started after my old contract ended and they are just not cancelling it. They don't listen and they don't pick up the phone also. I will go to police if they don't stop it.

Never choose them. I repeat never.

Service is good

I am overall satisfied but on this occasion my SIM card delivery was delayed and I was left without a connection for four days.

Very professional and quick service.

So friendly, easy and very helpful !! English costumer service .. Great costumer service!!

very frustrating to call their support center. Either they do not pick up because of their stupid automated system that could not recognize my number no matter what, or they pick up but they are very incompetent and not helpful at all. I had a contract and still after 48 hours could not be activated for one reason or another despite that the identification went smoothly and instantaneously, but the e-Sim card could not be activated and nobody seems to be of any help.
I am very frustrated for I wasted already 2-3 hours just waiting on the phone and getting useless support.

UPDATE am 28.Nov:
Es ist bemerkenswert, wie schnell man hier eine Antwort von Ihnen erhält. Allerdings ist es sehr frustrierend, dass Sie telefonisch oder per E-Mail schwer erreichbar sind – insbesondere, wenn man mehr als 15 Minuten in der Warteschleife verbringen muss oder über 3 Tage auf eine Antwort per E-Mail warten muss, um ein Problem zu klären.

1- I had more than four times telephone calls with them that ended up resulting in contracts that I didn’t ask for. Once it was very unclear what I was told, and the other times they say they just send me information to see, but that is not information to just see, it’s a subscription contract to something else.
2- At time due I changed from Klarmobil to Freenet which is a subsidiary, then I had a lot of headaches with Freenet that I decided to change my contract provider and I asked „Freenet“ for data deletion, but I received a confirmation from Klarmobil, although I didn’t want to delete my data from Klarmobil because I had two years contract as well as three unread notifications in my app. Now comes the funny part:
3- I want to take my old number with me and the new provider told me that it has been rejected from the old provider and they said that the number is unknown! So imagine the stress!
So since when I wrote Freenet for data deletion Klarmobil answers, and I was guessing that it’s caused because of data deletion, I wrote Klarmobil and they said they can’t find it and I’m writing the number wrong and I have to check my number on my invoices! Knowing how messy it is, then I wrote Freenet and voila! the number is there!, and Klarmobil only sent me two times generic emails „check on your invoice“! Freenet and Klarmobil are connected for data deletion but not when it comes to servicing to at least write: „please contact Freenet“. After the two messages it was no wild guess that I should contact Freenet, but I always had to write and wait for a reply, it of course took time and stressing that I’m losing time and my number will be sold to someone else.
Luckily at least that one is solved but I panicked and I put everything on the side and only followed this matter for two hours. If I was not fast enough I don’t know what would’ve happen.

I don't understand all the positive reviews. I had a 24-month contract with them and it was nothing but frustration. I was charged when I shouldn't have been, they wasted many hours of my time, the website / app don't work, and they kept "other" services running even after acknowledging receipt of a cancelation letter. All communication was with them in German and there were no communication difficulties, but I prefer writing serious reviews in English still.

- I have a confirmed email cancelation of the contract from them from 5 months ago and they're still charging me 2 months after this confirmed end date. I just had to wait 30 minutes on their service line for them to tell me that although my cell phone number is canceled they're charging me for other "extra services", something having to do with audiobooks which I never ordered. The agent understood my frustration and was kind, but said, "I am really sorry but I can only cancel it now so you don't get charged from now on. So I still have had to pay ~30 euros extra after the agreed upon contract end date. I don't understand how what they're doing could be legal, but it's not enough money for me to waste more time going after it.
- Over the 2 years, their website rarely worked for me, the iOS app never worked at all. Spinning beachballs, unknown errors, please try again laters, I have had everything. Horrible UX. It means I couldn't even get my last invoice now because I cannot access it online.
- when I told them on the phone 6 months ago (before I had written an email) that I'm canceling, they kept calling at least 5 more times, pushing me to renew. I asked why they are still calling and one excuse was to the effect, "yeah, but we have to call you because your contract is ending soon".
- This is partially my fault, but their booking services to lock out roaming charges when traveling EU / outside EU were confusing and resulted in + 100 euro charges three times. My new service is so clear and plain and so were other services in the past that it felt like this was intentional.
- Their CS agents are kind and polite, but are clearly trained to say sorry but not budge on any incorrect billing. They even admit it's their fault, but I could not get a refund.
- They use a good cell network so it worked fine. However, now I pay the same price now for the even better Telekom network and their app works great, has great UX, great EU romaing policies / functionality, no BS, and I already tried it abroad and there were no problems.

the Customer support is awesome and very supportive.

Super unhappy, I get repeated emails to change my contract as it's due for renewal. I ask if I can stay on my current plan, and they told me I couldn't. Then, after finding a new deal (with less value), I see in the fine print I could have extended with no issues. THEN, I get an email for an even better offer. I call them, and I get a response I need to email them to cancel my current extension, and then call them AGAIN to take them up on the offer. Only problem: there is no email address anywhere to be found.

I'm quite unhappy over this as it's taking up a lot of time, which is a shame because I was quite happy about the product and service.

The stability of costs. Unlike most companies you have not raised costs under the disguise of inflation. And your customer service is good. One negative point though is when you message me that my GB's are running low and ask me to pay for more by answering 100mb, 1gb, 2gb, my request for 2gb is not acknowledged. That is confusing for me. Otherwise all is good.

Good app, great price, excellent sync with CHECK24.
It's the second time I'm using klarmobil.de in Germany through CHECK24 with all the bonuses. Unfortunately, never had a decent offer to stay. Hope at the end of this contract will receive an honest offer or will change once again.

**Review: 1 Star**

I've been struggling for 20 days to get either an eSIM or a physical SIM card from Klarmobil. My phone number is tied to all my personal accounts, and now I'm completely stuck. There’s no real customer service anymore. When I call 040348585300, I enter all my details correctly, but then an automated message says there’s no replacement card in my name and disconnects. The customer support is rude and unhelpful, repeatedly telling me to call the same number where I can't reach anyone. I feel trapped by Klarmobil due to their low prices but regret my decision deeply. No SIM card yet, and no hope of getting one. I expect no real help, just an automated response asking me to contact them through a link that never works.

Easy to deal with. The mobile phone contract offers are great. Easy to setup and get going. Would highly recommend.

It was very easy to conclude the contract. Everything was online. The transfer of my number from the formal provider also went smooth. I practically just had to watch and do nothing. Klarmobile also has an app which enables you to stay on track concerning bills and data used. I am very happy at the moment. I sometimes travel out of Germany for work, let us wait and see what for bill I will get and how reliable they work in roaming

servic, quality, price, expertise most of the service people
