Blau Mobilfunk Reviews 

Customer service is really bad. They just randomly end the call or conversation when they feel like it because they assume youre done. Theres not even a goodbye or anything, at least confirm that your customer dont have anything else to ask you.

Subject: Missing Promotional Smartwatch (Active 5) from My Order

Hello,

I received my order containing the Xiaomi Note 15 Pro and my mobile plan on July 30, 2026. However, the promotional Active 5 smartwatch that was supposed to be included with the package was not delivered.

Furthermore, I am unable to reach customer service through the usual channels. Could you please check my order status and help me resolve this missing item issue as soon as possible?

Best regards,
Çağlar Salkım

Betreff: Fehlende Aktions-Smartwatch (Active 5) bei meiner Bestellung

Sehr geehrte Damen und Herren,

ich habe am 30.07.2026 meine Bestellung (Xiaomi Note 15 Pro inklusive Mobilfunkvertrag) erhalten. Die als Aktion beworbene Active 5 Smartwatch, die Teil der Lieferung sein sollte, war jedoch nicht im Paket enthalten.

Leider konnte ich bisher niemanden über den Kundenservice erreichen. Könnten Sie bitte den Status meiner Bestellung überprüfen und mir bei der Lieferung des fehlenden Artikels behilflich sein?

Mit freundlichen Grüßen,
Çağlar Salkım

Completely stupid system, i put my name incorrectly on that stupid system. There is no way to update, you have to send an email and wait a couple of days until they edit the name. "A small edit button will solve the case" , you need to fire your customer satisfaction manager

Extremely bad! Never again. I bought a prepaid sim card, I wasn't able to activate it until 12-days after the purchase date due to a problem they had on their website. Their customer service didn't reply to my requests for refund too! It's really really bad and they are so beaurocratic. Next time, I'll definitely deal with another provider. NEVER AGAIN Blau!

Pure scam,don't buy it
They sell psychical simcards that won't activate.

I requested an eSIM. Before activating it, I was told to deactivate my previous SIM.

3 weeks later, I just got the third QR which is not working, their customer support just blames me of course. The refuse to give me money back for the weeks I have been without any line at all

My login with the phone number blau gave me never worked. Not a problem while I had the subscription, but it means I can't see my bills.
I have left the country and despite a few phone calls to their customer service to cancel my subscription Blau continues to chatge me 4 EUR every month. I can't see why as I can't log in.
So just don't. Stay away from them.

Never knew ordering new simcard can be so difficult! It doesn't work on their app or online. And their support chat is a dumb robot that points you back to app or online where ordering simcard is not possible due to technical error. And thats how it is for a week. I have ordered contract cancellation tough. What a joke

Great value while everything works. God forbid you should lose your phone or otherwise have to change anything. Broken processes, logical contradictions (activate your SIM by getting an SMS?), variable support (some good, some bad), multiple points of entry (app and web site have different functionality, but you need both, call bot gives you yet another URL for SIM activation), broken tech (confirmation emails never come) and two call centres. If I weren't also with Telekom I would be incommunicado. That's Spanish.

I ordered an eSIM from their meinBlau page and the moment I ordered it my network was gone. In order to activate the eSIM, I should be receiving an SMS but without my network I cannot receive anything.

And now I have to wait couple of days to receive the activation QR Code via post because they cannot send it via email.

Now I am without network for I dont know how many days. WHAT A JOKE

Their system made a mistake, and they don't want to give me my money back, even though I have proof.
BLAU is the WORST company because it belonged to TELEFONICA ESPAÑA, which is a piece of garbage.
I am Spanish and I know them very well, unfortunately.

The customer service is the worst. They have Indians who are instructed not to think and just follow the instructions they are given. It is infuriating.

extremely bad service- they have well trained personell as far as it comes to selling you a contract, but when there is a service issue i tried to solve it with 4 different people who all couldnt even fully speak my language- its horrible im extremely unsatisfied with what i got now- i bought it with a promise that wasnt upheld. Would never sign again

They lack the capacity, which often results in no mobile data being available despite full coverage.

No mobile provider could deserve zero stars more than Blau. Had a leftover credit in my prepaid account from my last tariff purchase which literally just disappeared, called customer service and they told me it been used to automatically renew my tariff and I had to top up 15 euros in order to complete the purchase but when I toped up that also just disappeared yet the tariff never actually started working. Have now called customer service multiple times and have just been told they're forwarding the issue to their finance team and I'll get my money back or that the finance team will activate the tariff for me. Utterly useless

Absolute awful service.

Blau.de started taking for my account multiple times a day by 10 euro at a transaction without any explanation and reason.
Today they took 70 euro. Yesterday they took 20. The day before 10. Totally for this month so far is 170 euro.

I do not even see those money in their system - they are just deducted from my account and are gone.

Service (hotilne) is awful. Email contact form is useless.

And the best part - you cannot complain to anyone, you cannot prevent them from taking money from your account!!!

Scammers. Didnt send me my sim card neither any code for anything. Right now they are taking my money while giving ZERO service to me and they wont let me cancel anything or give me new codes or a sim card just because i dont speak German but they did opened me a profile to scam me while i still dont speak German. Never ever seen a worst company than this. When i have enough money, ill sue them hard. Ill take every penny they stole from me. They are just disgusting...

Card didn't work, website, hotlines and app are confusing

If a minus rating exists, certainly I Choose it. Beware all customers!! I am stating a fact that this company is irresponsible and very slow in response, I have the right to terminate my contract under the 14-day German cancelation policy but up until now for 10 months it has not proceeded.

Imagine I HAVE TO FORCELY PAY 18 € x 24 = 432 €.

CAREFUL DO NOT WASTE YOUR MONEY WITH THIS COMPANY.

I have never seen such a bad company in all around the world. They are deceiving people. I have almost been waiting for the Simcard for 3 months even though they took the payment from my account. Whenever I contact their customer service, they are telling me that the card is sent you your post but nothing is happening. They told me that they will send an E-sim but they are now claiming that they don't have E-sim. I can't imagine how a company claims that they have english support but they don't. I requested my money back and the cancellation of my agreement, and no answer. Stay away from this company!

Ordered a pre paid SIM card. Received it then tried the identification process which sent me round in circles. The provided link sends you directly to SIM activation which you can only do if you have the Handy Number which hadn't been provided. Customer service experience very poor. Personnel unfriendly/unhelpful. Trying to return the SIM card now and get my money back.
