Hello,We left Germany over a year ago now. We still had money left to pay on the iPhone we took with one mobile contract so carried on paying it. Now I want to check how long is left on the contract to pay, or just to arrange to outright pay anything left, BUT I can no longer log into my O2 account as I don’t have the number linked to the account anymore as the German o2 contracts have been cancelled.Can I please get some help in sorting this out?

Hello,I signed the sim-card contract with O2 for 24 months on the 05.11.2022. I am from Ukraine and I am going back there on 20.02.2023 (I have the tickets), so I already have my de-registration paper. I read on the forum here that I’m supposed to send this de-registration form and a proof that I’ll actually stay abroad (paper from the landlord or employer) to Telefonica address.The problems are: first of, I do not rent an apartment, I own one, so there is no landlord I can ask to write anything. Secondly, I work for myself and do not have an employer I work for. So, what am I supposed to do now? What documents can be sent as a proof, apart from de-registration paper (maybe my Ukrainian passport would work)? And on what address should I send all documents? Will there be any fees? If possible, please provide the example of how this letter should be written, because German is not my first language.Thank you beforehand!

How can I re-linked my email with my O2

How can I get new sim card - lost the sim

Hi O2 Support,I am xxxxxxxxxxxxphone number -017xxxxxxxxxxx15.I have an O2 mobile contract for my above-mentioned phone number.But for the last few months I have also been paying for another contract.When I contact customer service, they say I have two contracts and O2 sent me a new sim card to my address.When the customer service guy calls me for promotion, I tell him that I don’t need any new contracts or numbers.When O2 charges me this bill on the first month, I already informed the O2 customer service and the person who talked with me on phone told me that he will escalate the issue and the amount will be refunded.But still am paying this amount every month. If you check on your system, you can see that I never used the new number. And the letter which you sent was my old address.I don’t need any new contracts or any number. I just need only one number which is – 017xxxxxxxxx15.Please cancel my all-other contracts. I never a

Swapped to eSim on my new iPhone 16 Pro Max, now I get a constant voicemail notification.

hi, I currently have an eSim and bought a new phone and have been trying to link it to my new phone but to no avail so I decided to call O2 and have them cancel my current contract which I thought would be canceled immediately but unfortunately it didn't as it is a two year contract. The person then put me through to someone who was willing to help me keep my current O2 number but then use it on a different phone and when I told the person about canceling my contract they offered me a different plan and we ended up signing a contract. It was only after the call that I realized my current contract doesn't end until 31st January 2026 and I want to cancel the contract I recently signed.I look forward to your answers, thank you

Hi there,I did the “rufnummernmitnahme” and ported my old Vodafone number to a new O2 contract. Got SMS as well as E-mail that confirmed the number was successfully ported on 06.05.2025. However, when calling others, no caller ID will be showed to others instead of my ported number….. Found some questions in the community, solutions (i.e. restart, using another cellphone) were not working. Also checked the settings of my iphone, “show my caller ID” is on. Could you please check whether the “caller ID display” is suppressed or not in your background system?Thanks in advance.

Your website is so annoying, so complicated and unprofessional, i want to change my bank so i am changing my bank details, other services were so easy but o2, was causing me headache, kindly give me a more precise way to change my bank details.

Hello O2 Team,urgent Matter here: My 2 Multisimcard are not functioning as i have just tried to insert them today. I purchase the phone last April 1,2025 and they said everything was okay. In addition my previous contract is up to May 3,2025 only. So we badly needed this tommorow. The iphone has the e.sim and functioning well, but the other 2 sim cards has no signal and cannot call other numbers and we put it on to the other two phones. Please kindly informed the solution asap. ThanksSincerely,Ramil

Hello! 1 months ago to buy phone with monthly payment from O2 I went to O2 in Friedrichstrasse Berlin. He applied for the phone and made me a sim card contract my phone application rejected so I wanted to cancel the contract in the same day. He took back my contract and sim card and he said he send cancellation request and give me a document written by hand. I didn’t trust the guy so I requested cancellation by myself as well and I got a e mail that says it processed. But today I have got a bill 20 euros from O2 that the number which I don’t have possession. What should I do right now? Should I sue O2 to get cancellation from a sim card that I don’t have? Why they are not just cancel? 

Dear O2 Support Team,I am writing to report a serious issue with my mobile internet connection. Despite being on a contract with a speed of up to 300 Mbit/s, I am currently experiencing download speeds of only 3.17 Mbit/s and upload speeds of 514 Kbit/s, as shown in the attached screenshot from a recent speed test.This issue persists whether I am connected to 5G or 4G. I have tested both options and the speed remains equally low.My address is:Langbürgener Straße, 81549 MünchenI chose this plan specifically because I rely on a stable and fast internet connection. Given the current situation, I am unable to use the internet as needed.Could you please urgently check if there are any network issues in my area or with my connection
