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

I received an email that my order has been sent and have been waiting for it, only to see that it has been returned to sender.What happened? Will it be sent again to me or will my order be cancelled? Can I order a new one right now?

It took me two days to register. It's not for me. Please cancel my contract. I signed the contract in Paderborn on 10/02/2026 at around 8 PM. Registration was very easy, but cancellation is very difficult. Of course, it might be easy for you, not for me.

Hi O2 Support team,2 years ago I have relocated to different city. The DSL line was moved, thanks to the DSL line I have the Kombi option on my 2 other contracts - at least in theory.two years ago was deleted the Kombi from one of my mobile contract - and noone knows why. Youi have helped me here by putting some 2 years discount on my contract which was the same amount as the kombi.unfortunatelly it is gone after 2 years.Can you fix the Kombi option for the phone number with ends with 48 ? (best would be to reactivate the kombi again so I do not need to come here with the same problem again.)the other mobile contract have no such problems. Thank you

Hello,I’m new in Germany so my dad got me an O2 number I saw an extra charge of 7.99 for “added services”  but I haven’t subscribed to anything. I later found out it was for Qello music streaming. I didn’t even know what that was 1 hour ago. The deduction has been going on for two months and I don’t even have the Qello app on my phone. I have been able to cancel it but how do I get a refund ?Thank you.

I transferred money to pay bills and missed customer number since 4 months ago, it seems my money did not reach to O2. Last week, I was blocked outgoing calls, I called to billing departments and they can not speak english, Thus I sent an email to Impressum and did not receive any further updates. What should I do next?The monthly bills has been deducted, do the bills need to be paid full amount to continue network?Ps.1 all bills had been paid.Edit o2_Kathi 09.02.26 Moved from the section o2 Mobilfunk to English o2 Community

Hi, I hope i may get clear answer from here. It is my first time to experience today that I cannot connect other devices. I usually use everyday my O2 sim as hotspot for my printer, other phone and laptop. Is it possible that O2 automatically blocked this feature? I pay 29,99 per month for unlimited internet so I don't see any problem about it because I routinely hotspot device since I got this sim. Or is there an error for today? Enlighten me please. Thanks!

First of all, I would like to say that I am very disappointed with O2 service. This is the worst customer service I have ever experienced.I have complained several times since October about my contract and my bill, as O2 made a mistake. I have called several times and filled out a cancellation form multiple times.I cancelled my phone and number contract on early September 2025, but somehow only the phone contract was cancelled and the number contract not. So I have 2 phone numbers now. I tried to call the customer service, and they said I had to send a written letter. I did that in October, but no answer until now. I called again and again, but still no answer and no solution. I called again last week, and they told me to fill a Sonderkündigungsform online. I did that, only to get a letter from O2 saying that they need my phone number. This does not make sense at all as I did everything online and O2 has my data!This week have filled again the for

I have to start off by saying my German is not good enough to have this conversation with the service team and it's so frustrating. I paid my bill since January only for my invoice to read that I have outstanding. I tried to call and luckily I was put on with someone who understood English, we were able to identify that the reason is that I did not put the customer number on the payment - I had forgotten. But I was able to identify what reference I used. Unfortunately we could not do anything about it that day because they were having issues with their database. The guy said I should call back on Friday and I did but unfortunately he wasn't the one and the lady who answered did not speak English. Now a month later my internet is cut off because of outstanding balance that i have already cleared. There is no email to contact, what can I do? I can not even call customer service  because no service to my phone. I work from home but I can not work because my internet is cut off too. It'

I got completely scammed by the O2 store at Muncher Freiheit and it is totally unacceptable and I want a refund and if possible cancellation of my contract.As a student who was trying to find a affordable sim card provided and I thought O2 would be a nice one. I went to this store in Muncher Freiheit and the guy there told me that this package (O2 Mobile M) is 20 euros per month and HE DID NOT MENTION ANY FIRST TIME OPENING FEES!!! He also gave me another sim card which he said it comes with the original one (O2 Mobile M) for free although I never asked for it. I just checked my mailbox to see that my first month fee is 80 euros!!! 4 times more than what I expected. The only reason I bought this sim card was the fact that it was 20 euros per month now I have to pay 80 euros. It shows 40 euros for the second sim card that I never asked for too. It is nothing but scam to tell me it is 20 euros and charge me 80 euros after making me sign things really fast.

Hallo! I was looking for the answer to my question "is there any possible way to change the language to English in the app" and found exact same question here with a negative reply. It was published 5 years ago. So is there any way now? If not... Why? 🤠  Thanks in advance for reply

Hello O2 team. I tried to move my phone number to Vodaphone, but it was not possible.I’ve liberated the number for 30 days. But Vodaphone replied that I only have 3 months after my contract with O2 ended, to process the portability to another company.Can you confirm if that information is correct, please?. Thank you very much.Edit o2_Kathi 09.02.26 Moved from the section o2 Mobilfunk to English o2 Community
