Hello 02, I set up a Handy SIM tarif one week ago online. I have received no confirmation email or SIM card in the post. Has the contract been set up? It’s not visable in ‘my o2’. Who can I contact?Edit: Thread moved to our english community, o2 Michi 23.06.2025

O2 wasn’t able to provide internet service to me. So I cancelled all contracts. In May I received an email message that they would debit my account. When I again (probably the 100th time) called customer service I was told that everything was cancelled and I wouldn’t receive another invoice/debit - the may charge would be the last one.Today I received AGAIN an email, that there was an invoice due in July.When I opened my account there was NOTHING. NO INVOICE, NO CHARGE, NO INFORMATION, NO RETURN EMAIL ADDRESS, NO TOLL FREE PHONE NUMBER. Be aware that I will issue a chargeback should you proceed with the debit.

Hi , I have a little situation with my current mobile package right now. I have 5 packages activated right now but I only need one. I only need Inklusive Datenvolume 25 GB and I don’t need the rest of the packages. Is there a way I can  cancel them. I can’t find it in the app.

Dear O2  Community,I would like to change the tariff of my contract to a more inexpensive one because it’s not affordable for me to pay this much. I tried to do it through calling your colleagues and they asked me a 4-digit code which I don’t have. Would you please tell me how can I have access to this code?Thanks for your time Edit o2_Sven: Moved to English o2 Community: Mobile

Someone from Support cancelled today during the morning my IPV4 dynamic IP address, putting me back into the CGNAT.I called technical support and they said it was a mistake that I needed to call Contract Support to give me back the ip address.I called them, I received the message that it was reactivated, but still, I dont have it.Could you please check that my IPV4 dynamic address is reactivated and that I am out of the CGNAT?I don´t understand how these mistakes can occur to randomly deactivate my IPV4...

For the last 2 days, my unlimited 300 GB speed mobile number is giving under 1 Mbits speed with esim. However within the same phone, I have my business line and it has more than 100 Mbits.I tried to restart phone, enable / disable airplane modes but none of it fixed it.I’m living in Haarxxxxxx with 6xxx postal code and I opened a support ticket but it’s not getting fixed either.Can this be related to my esim or is it something in general? Edit o2_Kathi 09.06.25 Moved from the section Mobilfunkdienste to English o2 Community: MobileEdit o2_Daniela 11.06.25 personal data hidden

I have been customer of O2 since 3 years. 3 sim cards, 1 Home internet and 2 mobile phone hardware purchase. I püd thousands of euros to O2. Then recently suddenly O2 started to change the conditions and charged the costs it was not existing in my agreement. I had to cancel Home internet. The worst thing today O2 withdraws 399 Euro which was agreed to be montly 21 Euro installment. Somehow O2 wanted to punish me, without informing me and without any invoice withdrew all my balance. O2 is really hating customers from whom they cannot gain anymore as they used to do.I never recommend to anybody who plans to come to O2. Be carefull you will be always facing bad experiences in the background. Employees got bonuses to deceive customers:(Edit o2_Bianca 13.05.25 08:37Uhr: Moved from o2 Mobilfunk Rechnung to English o2 Community Mobile

I released my O2 postpaid number on 04.06.2025. Following which I received an email confirmation with Gültigkeitsdatum Opt-in: 04.07.2025.After which I request for a number portability with new provider and O2 denied the request with reason:Bei der Portierung der Rufnummer 0151xxxxxx22 ist es zu einem Fehler gekommen. Die Fehlermeldung Ihres aktuellen Anbieters lautet: Portierung zu früh – Die Mitnahme der Rufnummer muss innerhalb von vier Monaten stattfinden. Ihre Kündigung beim aktuellen Anbieter ist zu einem späteren Datum hinterlegt.I have requested twice for portability and both requests rejected.Can someone from O2 help me port my number?

Hi,I recently extended/changed my contract from O2 smart online to O2 M on 02.06. I received emails and SMS that the contract will change from 02.06, but I also saw that the bill for O2 smart online is billed on 02.06. Therefore will I be paying for two contracts this month or only the new contract?thanks!Edit o2_Antje: Moved from Rechnung to English Community 

I have 2 contracts by O2.Since more than 2 weeks there are problems with an antenna in my area and internet is slow and unstable.I have been with O2 customer service multiple times being redirected over and over from one department to another.Technical department has confirmed that there is an issue with the antenna and there is no good 5G signal(for what it matters 4G LTE is also very bad) and if I do not have good internet I should close the contract due to missing parts which O2 supplies from China (technicians words, not mine).I have attempted to close the contract by phone, writing(email) to O2, writing to Nurmeberg office but no success.None of the offices reply, customer service just redirect from one department to another until they close the line on your face.I have allowed O2 to charge by bank for July(I had service in July), but will not allow to charge for August.There is no point to not have service, and charge my bank.I am working from home and this impacts my personal li

I am an international student. I have went to buy a contract sim of 20+ euros with unlimited internet but the agent in O2 shop said that offer has been cancelled on the day before and asked me there is only one offer of buying two sims and paying 35 euros for 100 GB per month and o2 only have that offer with least fees. Unfortunately I bought this because I trusted him and I had an urgency, later on the same day my friend contacted me and said she bought a sim with unlimited internet with 20+ euros from another shop in same city. Now I am paying 37 euros per month with only 100 Gb. I contacted O2 support multiple times and my call connected on May 2025 and the person said they dont know why I had to buy 2 sims and they really had an offer with unlimited or 300 GB. I went back to the same shop and asked for the explanation and they said they cant do anything about it because i have signed it. I am an international student who trusted O2 but this was too disappointing and this payment is

I switched to eSim for my german number, and since then roaming does not work in the eurozone, only in Germany. I am still paying for my data, nothing else has changed, I have done all the “fixes” suggested and still nothing.I called German customer service and have been hung up on repeatedly. I tried to switch from business to personal to get English hotline support and nothing.  I cannot log in when I am in France or Italy because I cannot receive SMS, or calls so then I am totally screwed when I get there for work. Then I come to Germany and try to fix it and get hung up on without any conversation whatsoever. This is the worst service ever. And still nothing is fixed. What do you suggest I do next? edit o2_Gerrit 28.05.2025 moved to English O₂ Community: Mobile
