Hello, today a Surf-Dayflat (1.49€ / 150MB) was automatically activated on my SIM even though I still have data left in my plan (o2 Prepaid S, about 13GB of 20GB remaining).Why was this dayflat activated while I still have data available? And is there a way to disable the automatic activation of Surf-Dayflat so it doesn’t happen again?

Hi all. I sent my new Samsung galaxy 25 ultra to repair cause of several issues, like overheating and camera colorless and people which I called told me they were hearing scratching sound when calling them. It is being already one month since i sent the phone to repair shop. They took ages to send the phone back to me and when I try the same issues were present, so i sent it back again. Still waiting for the phone back again but I do not think they can fix it since it is probably a hardware issue. The first time the repair shop sent the phone back to me, there was not description of what they did. To be honest I am struggling a lot doing my daily life without a phone. O2 shop not even gave a temporarily phone while the other one was sent to repair. Very unsatisfied with O2 service. Can I demand to have new S25 ultra galaxy, same model like the one i bought and sent to repair? Please help me outEdit:o2_Lea/06.10.2025/moved from the following articl

Hello dear 02 community Past two weeks my WiFi gets disconnected automatically. Every time it happens I log into this 02 app and click the Problemlösung and then follow the steps. It gets connected back. This repeats every other day. What could be the reason and solution? I haven't tried restarting the router because i had last year very bad experience from restarting it as the internet wouldn't get connected automatically and I had to call customer care. When the WiFi gets disconnected I checked the other devices just to make sure it was not the problem of my phone. The other devices also didn't have. So it is not the problem of my mobile or any other devices Could somebody help me? Thank you.  edit o2_Manga: verschoben von Mobilfunk zuhause nach Englisch: Mobile

Es ist nun schon der zweite Monat, in dem die automatische SEPA-Lastschrift für ein kürzlich gekauftes Handy nicht funktioniert. Die anderen Telefon- und SIM-Kartendienste funktionieren per Lastschrift einwandfrei. Da ich mich momentan im Urlaub befinde und Google Translate für die deutsche Übersetzung nutze, kann ich O2 von außerhalb Deutschlands nicht erreichen.Moved from o2 Mobilfunk: Rechnung → English o2 Community: Mobile and title edited // o2_Rebecca, 24.02.2026 20:43 Uhr 

Hi everyone,I received an email saying “Welcome to O2, here’s your new tariff” and the phone number listed is not a number I recognise. I went to my local O2 shop and the worker said she couldn’t find that number on anyone’s account, and it wasn’t showing on my account, so I didn’t need to worry about it. I then later received an email from a lawyer saying I owe them around 400 Euro for this random account. I don’t think it’s fraud or a scam, but you never know. I again couldn’t find this number in my contracts, though emails about it from O2 go to my same email as what I use to log in. I’ve tried to log in with the phone number but can’t receive texts to it obviously, and even if I reset the password to my account with that number as part of my login, it still takes me to my usual account page where this random phone is not listed anywhere! I don’t have 400 Euro laying around for possible fraud or a mistake in the O2 billing, etc. I didn’t want another contract and I haven’t

It seems there is a fraud/scam happening right now with O2 users. Recently I received an SMS about this Fightclub stuff and I never paid attention to it nor click the link. I ignored it and then next is that it already sent me welcome message. I still ignored it because I know it is a fraud/scam message. I did not worry because I did not do anything. To my surprise, I was already charged a membership fee not only 1 but 4 times. That easy, my account has been compromised and was charged directly. I felt the security level is a weak and to me it is very ALARMING!!!!!!!! I reported right away to O2 via email. They have not responded yet. Let see how it goes. I requested for a refund as well because this is a clear weakness in the security.07.03.2026 verschoben von o2_Katja aus Mobilfunkrechnung

Hello,I am unable to log in to my "Mein O2" account because the system will not send a verification code to my mobile number. Also most of the O2 stores are useless and rude, they say that they have no access to the prepaid, asking me questions like “Why are you using prepaid card”.The Issue: I have tried the password reset process multiple times, but no SMS arrives. I have checked my phone settings (Premium SMS is enabled, no blocks). Crucial Detail: I visited an O2 shop, and the employee(Finally a decent one) there was able to send an "Employee PIN" to my phone successfully. This proves my SIM and the network connection are working. The Problem: Despite my SIM working, the automated web-portal/app system is failing to route verification codes to me. Because I cannot log in, I cannot manage my contract or see my bills.

can someone please delete my community account (this account) as its stopping me from using the o2 application  Edit o2_Kathi 08.03.26 Moved from the section Mein o2 zu English o2 Community

Hello O2 Team,I have been a loyal O2 customer since 2012, currently on the O2 Blue All-in L plan (paying €44.99/month).To be honest, this legacy plan is no longer practical or beneficial for my current needs. I am at a point where I am considering switching to another provider unless I can find a competitive reason to stay with O2.I would like to renew my contract and switch to the O2 Mobile Unlimited Max (2025/2026) plan. Since I am a Google Pixel user, I am looking for an Android tablet for my studies (specifically the Samsung Galaxy Tab S10 FE+ or a similar S-series model with stylus support).My goal is to keep my total monthly bill (Tariff + Tablet) around my current €44.99 or better yet LOWER.Could a moderator please look into my account and send me a personalized offer via email? Since I am still working on my German, I would prefer to handle this via email r

Hello everyone,I would really appreciate some guidance regarding my ongoing case with O2, as I am currently stuck between O2 support and Arvato logistics.I purchased a Google Pixel 9 Pro through an O2 My-Handy contract. Within the statutory warranty period, the device developed a repeated System UI defect. Google issued multiple replacements (several RMAs), but the same issue occurred again.O2 confirmed in writing that I am entitled to a Rückabwicklung (contract cancellation and refund) after unsuccessful repair attempts.I sent the device back as instructed, but Arvato rejected the return stating that repair/replacement documents were missing, even though I have RMA confirmations. The device is currently with Arvato, and I received a letter saying I would need to arrange delivery at my own cost, which I believe is incorrect since this is a warranty defect case.I have already contacted O2 via the contact form and submitted all documents again, but I

Dear Customer Service,I am contacting you because I am unable to confirm my email address in the Mein 02 service area. I received the following message: "Leider haben Sie Ihre E-Mail Adresse noch nicht bestätigt. Wir empfehlen Ihnen dringend, Ihre aktuelle E-Mail Adresse in Ihren Kontaktdaten im Servicebereich Mein 02 zu bestätigen. Damit stellen Sie sicher, dass vertrauliche Informationen Sie schnell und ressourcenschonend erreichen."However, I am currently receiving emails from 02 without any issue, which makes me unsure about what exactly still needs to be confirmed. I do not know how to complete the email verification process. I have not received any confirmation email, or I may have missed the necessary steps.Could you please assist me in confirming my email address or resend the verification link?Thank you very much for your help. Edit o2_Kathi 03.03.26 Moved from the section o2 Mobilfunk to English o2 Comm

I got scammed by this guy who was at O2 shop Am Harras. First of all he was extremely disrespectful towards me for no reason. I went to the shop in January to get my contract extended, I was enquiring about different offers, the guy was not cordial at all to inform what offers are cost effective. Anyhow, I got my contract extended and he asked me to sign the contract. While I was about to leave he told me that you get this free sim card. I didnt need it but he asked to keep it and I just put it in my bag. Today When I checked my invoice I was charged 73 euros. When I called customer care to enquire about why I was charged so much, I got to know that there are two contracts active on my profile. I had no idea about it. WHEN I WENT TO SHOP I WAS TOLD THAT YOUR CONTRACT IS EXTENDED AND WAS NOT INFORMED THAT HE IS MAKING ANOTHER CONTRACT IN MY NAME. THIS IS A FRAUD, I REQUEST TO IMMEDIATELY CANCEL MY SECOND CONTRACT AND REFUND MY MONEY.I have a feeling this guy did it INTE

I can’t recieve SMS after activating a new eSIM. I have checked my SMS settings and the correct SIM is selected to be the SMS recipient, i even tried changing it then changing it back. Can someone check my phone number ending in 5065 has SMS configured correctly? I need to receive my authentication code via SMS for my apps.

Unfortunately, I feel so let down by O2. On the 31st of January I called English hotline and purchased an international data roaming package and when I landed in Turkey I turn on my data to use my package but instead I was charged immediately with 60 euros which is the roaming limit that was currently active. Afterwards it was blocked for me to use even the package that I purchased.From what I understood the problem was the package I  purchased was supposed to be active on midnight, not immediately. and this was not communicated with me during my call with the hotline service. Now when I call the hotline service again and they investigate this told me that they see that I call them on 31st of January but they cannot confirm if they data is purchased which is not helpful at all why the conversations are being recorded if they will not help these kind of situations where customers are not able to get a proper service and pay extra for nothing? On top of that they

I want to share my experience here because I'm really frustrated and want to know if others have experienced something similar. I signed up last year and took out several mobile phone contracts. This year I moved, and without my knowledge, important letters were sent to my old address, which I never received. These letters apparently concerned outstanding bills. Two months later, I logged into the portal and saw that payments were missing and that there were already termination warnings. I immediately transferred all the outstanding amounts and updated my address. Unfortunately, my MacBook contract was still terminated, leaving a balance of €1,200. After that, I contacted chat support – unfortunately, that wasn't very helpful. I was told I had to call the finance department. I explained that I don't speak German and asked for another way to contact them. The answer was no. Frankly, I find that very unusual these days. Finally, I found someone who called f

Hello,I’m hoping for some guidance. I need to cancel my mobile contract early due to leaving the country. I have my de-registration certificate, but I don’t know what to provide as my other document. I’m leaving the country due to being made redundant, and returning to my home in the U.K..As I am a U.K. citizen, I will not be required to “register” anywhere, as is the case in Germany, so I will not get a registration certificate either.I do not have an employer so that option does not work for me.I will not have a new tenancy agreement, as I have a mortgage on my house in the U.K.. Will a page from a downloaded utility bill with my address on it be sufficient? The next problem I’m having is that a 250kb pdf document and a 2.8mb photo of my abmeldung cannot be uploaded - the form rejects it, saying there is a problem with the file size, whilst also saying each file must be under 3mb, which they are…thanks in advance for any help you can offer

I recently got a new contract which comes with new number. I haven’t activated it, I want to shift this contract to my existing sim number. How can I shift it? 

Good evening, I apologize, but I've had this problem for over a week now, and they even changed my SIM card, but nothing has changed. I have an iPhone 16 Pro Max, and I can't connect to the internet because it says there's a PDP code authentication error. And nobody is giving me a solution. Edit o2_Kathi 19.02.26 Moved from the section Broadband to Mobile + Title adapted for a better overview
