Blau Mobilfunk Reviews 

I find it unacceptable that they do not have any customer service for existing customers. Even the chat is "accidentally" never working.

I was actually happy with the rates they have and how easy to use the website is. But a company that avoids contact with their customers should just not exist.

They are destroying my business! I'm self-employed and EVERY customer has my Number. I wanted to switch from pre-paid to a new contract, they promised me "immediate" change with my number. A I registered the Sim Card they suddenly tell me it will take 3 days, now I got an E-Mail that it will take about a week! A WEEK where all my customers call a dead number!! Are u serious?!

I've been a pre-paid subscriber to Blau for over 1 year now and I decided to get a new phone, so I went to their website to buy a 24 month subscription and a phone.

They rejected my phone request (it was iPhone SE), but said that they will give me the 24 month subscription, that I only wanted with the phone.

I immediately canceled, sent them two emails as per the cancellation instructions and they never replied.

After that, they sent me an email letting me know that they are sending my SIM via post.

Now I sent them a FAX and will send them a mail by post as well.

In addition to this, their services are bad. Customer support is horrible and unhelpful. They just hang up on you.

Their mobile service is also excruciatingly painful. I only get 3G tops and most of the time it's very slow and doesn't work consistently.

The only reason I've been a customer of theirs is because I used to have Simyo and they got bought by Blau.

Unsatisfying costumer service. I had problems with a booked data plan which they didn't activate.
Their app told me that the plan had been booked but that it could take up to 48 hours to activate it!! Really ??? Since the App told me that they already charged me and that there's only one cent left on my prepaid sim, I didn't deactivate my mobile data. Long story short..: At the end of the day they didn't charge me for the data plan like their App told me but charged me the whole 10€ for data without a plan and the costumer service didn't even care about it.

If I could give zero ... I would have given that.. such a awful company. They don't register for foriegners. When I asked for activation.. the customer service is rude. They don't have manners. As if they are doing favour on others. When asked to return the money they declined. They don't have a shop and they say you can't have a sim in Germany only EU citizens have right. They don't want to return money. I went to Vodafone, O2 they readily agreed to register... Blau has Simply worst company policy.. robber's

Customer service is...well, I'm not sure the word "service" is even appropriate here, they are absolutely horrible.

After losing my phone, I have been battling with them for over a month to get a new sim card. O2 locations (Blau has merged with O2) have told me that they can't do it, were incredibly rude, and sent me on a wild goose chase through 5 different shops all over the city (one which didn't even exist). I was told to use the website, but in order to log in, the password is sent...to my phone. Since my German isn't great, I tried to contact customer service online so that I can better translate. The customer service person was combative, essentially told me to f*** off since I couldn't log in, and refused to help me in any way or find someone who could before abruptly terminating the chat. It seems the only way to even speak to them is to call the hotline, where of course there is no record of the conversation.
I am no longer trying to get my sim card back. I am trying to cancel my contract so that I never ever have to deal with this horrible company again.

Poor service, high costs, customer service doesn't exist. No English language support.

I could barely find an email address to contact them through, since they only had phone numbers to call, where operators wouldn't talk to you if you spoke English. After sending them an email, I got a reply after 4 months.

Former simyo customer, who were pretty decent before these guys took over.

I want to be done with them and just take my phone number and leave.

There was a problem with my phone and the free line was only for people wanting to join. For problems I had to pay to talk to someone (no emails either) and when I was asking a question about something technical he said that I didnt understand he just hung up. (was not angry and fighting, but was asking to explain his comment that says each time I dont get an sms I should put my sim card in an other phone and wait until it loads and then put back in my phone. I then asked why this is the only solution and he was annoyed and said I can only do this and then hung up.)

I had been a satisfied Simyo customer for 3 years. The website was user-friendly, the customer service answered quickly and the prepaid options fit my needs (I basically only needed data and for some reason that is so expensive and hard to get in Germany without also getting free text or some other useless thing you don't need if you have data).
Then, all of a sudden, with only a 4 day warning, they tell me via a text message that they are going to change to BLAU (This should have been given at least a 3 month warning in my opinion), but they reassure me nothing will change.

Instead, EVERYTHING changes:
- no more credit card payment (only a direct bank payment that doesn't work)
- no more customer service via email, their phone line is only for new customers (WTAF, are they thinking?? How about giving SERVICE to the customers who are paying your salary already??)
- their chat function never works and is constantly too busy and breaks down.
- For 3 WEEEKS I haven't been able to use my phone when I am not connected to wifi because I can't save the bank data and thus cannot put money on my account. So I basically can't do anything but call 911 when I'm out and about.

I tried to change provider and wanted to take my number with me, but Blue told my new provider that this wasn't possible because I haven't cancelled with them - which is rather ironic because on Blue's website, it says it's not necessary to cancel when you only have prepaid. And they actually want me to send a letter made out of paper to cancel something they claim on their website I don't have to cancel.

I am absolutely FURIOUS with these people. I have now given up completely, am getting a new number with my new provider (who's way cheaper anyway: go Simply Tel, great customer service too) and BLAU can seriously go eff themselves. I hope they loose every single customer they have. Nobody needs a company like them.

As the title says, I withdrew my sign up for a contract with Blau the day after I signed up via internet, well within the legal 2 week window to do this. I used their own form and sent it both via mail and fax. I know they got it since I got a confirmation the email was received. I haven't used the subscription at all. I've been talking to both phone support and chat support and repeatedly emailed them. The only answer I get is that they've had a lot to do and that I should be patient. It's now been three months. They keep withdrawing money from my account. I'm pretty sure they're breaking the law at this point so I need to look into how to proceed with this legally. This is by far the worst treatment I've ever had from a company.

If you want to ruin your day, give them a call...
Their computer telephone system is ridiculous, so with no help as to what to do, looks like its already time to change providers. Thank god I tried it out with no contract..
