Сегодня с 14:00 низкая скорость интернета до 40 кб/сек. Ни одна страница не загружается в браузере. Сам роутер был перезагружен, полностью отключен от сети и сброшен до заводских настроек. Ничего не помогло. У меня тариф О2 на дом 1000 мб/с. Сегодня воскресенье, горячая линия не работает. Что я должен делать? Провайдеру приходится самому перезапускать линию.

Hello,I need help with my O2 prepaid SIM cards.I originally ordered one SIM card, but it got lost in delivery, so I ordered a replacement. Now both SIMs were delivered. I activated the first one and inserted the SIM card, but it was not working. I spoke to someone from O2 customer service and they told me that either of the SIMs should work.Since the first one was not working, I inserted the second SIM and activated that one as well. The second SIM is working.Now both SIM cards are activated, and I am worried that money will be deducted from my account for both cards. I only want to use the working SIM and I would like to cancel/deactivate the other one.I am an international student and I speak English, so I would really appreciate clear instructions on what I should do next.Also I have not yet been asked for my identification , so help on that would be great too. Thank you for your help. 

Ever since i bought this O2 Unlimited Max because of the 5g and 300 mbps speed i only had problem.On first day i had a maximim speed of 25 mbps thereafter  i been down to 2 mbps even 1 mbps.It keeps stuttering, buffering or go down every now and then.I have new Huawei cpe h153-381 5G router and tried it with other cards without any problems.Then putting in the O2 simcard and netspeed goes down.I pay for 250 - 300 mbps with UNLIMITED data as they say it is but its not its actually 980 gb of data and not unlimited. Whats going on with this company ? Its all fake advertising to scam people or what ?

Could you please delete my Community account? I need to log in to my new account (a new contract) using my current email address.

Good day everyone, I signed a contract with o2 physically from their store in Frankfurt 7 days ago and got a phone on a 24 month installment plan. A week later i realize that I would have been better of just getting the phone without a sim contract as O2 has better prepaid offers. is there any possibility I can cancel my sim contract and switch to prepaid plans while keeping my handy contract as it is? I know contracts signed physically can not be cancelled within 14 days but I also read that if i get a phone with it, it is possible. Any advice will be highly appreciated. Thank you. o2_Giulia, 06.12.2025, 09:43: verschoben von O₂ my Handy & Finanzierung zu English O₂ Community: Mobile

Hello team, I had ordered for a new O2 cable connection and received the modem today.  However, the activation date is almost a month from now. The mail I received also said a technician appointment is not required. Considering the following, would it be possible to activate my connection sooner? Any help would be greatly appreciated. Edit o2_Kathi 25.11.25 Moved from the section DSL, Kabel & Glasfaser zu English o2 Community

I’m getting non-stop spam calls for over two months nowMostly from Austria, France and Spain. In two Months total 400 calls. How to make them stop. They Impersonate as PayPal Verification. I don't want to use unknow callers function as I cant block local unknown German numbers. Let me know. 

I´ve been using O2 about three years. Last 6 months I experience regular (2-4 times per day) VDSL disconnection at the same time. So I have to reload my router 2-4 times every day accordingly, also the home infrastructure (repeaters and smart IoT). I´m quite busy and can´t afford this job. So I contacted the technical support about four times to fix the issue. They opened a ticket and resolved it within two hours without doing anything.So now, I understand it´s the German quality and I have to move to something else, not German. I expect to get Starlink today, test it. If it´s good quality I will say goodbye and cancel the contract.Could you explain why VDSL is disconnected regularly and technical support does nothing (curiosity before saying goodbye)?

Hello, I had a problem with my order. I ordered a macbook pro 5 and it is handed to dhl. I told support team my age many times but they still wrote my birthday incorrectly. Instead of 29 nov they wrote 28. I don’t know what to do know and I dont want to cancel the order. And I ordered it through a call so I can’t login and change my data edit o2_Manga: verschoben von Meino2 zu Englisch: Mobile

Hello,I have a DSL connection from O2. I moved in to a new apartment last month and I got the existing contract transferred to my name. I am receiving letters regarding the SEPA authorisation but unable to do it online. I am unable to create my account as well. Please help. I do not want the payment process to be manual and auto-deduct is the best option for me. But unable to set-up. Thanks.Regards,ArijEdit o2_Larissa: transfered to English o2 Community: Broadband / DSL

Hi,My Prepaid M plan was automatically renewed despite having no balance on my account. For about a year, the plan was only renewed when I topped up myself. However, this time the renewal occurred without my knowledge.I currently need call minutes, so I would like to switch to a different plan and do not intend to use the current plan this month. Can you help me with reversing this renewal or changing my plan?Thanks!

Hello O2 team,I need your support regarding wrong advice/misleading information I received in an O2 Shop.What happened: On 13.11.2024, I visited an O2 Shop. I wanted to get an offer for a Google Pixel 10 Pro + Watch 4. The employee told me that in order to get this offer, she needed to cancel my existing contract (“Mobile Unlimited on Demand Flex”). She then created a new tariff for me (Mobile M Online) and told me that it would cost €14.99 per month because of a discount. I agreed based on this price. I have now learned that the real price is €29.99 per month, and the discount she applied is a Kombi-Vorteil, which only works if I have two active contracts. However, the employee cancelled my old contract her

My cable internet is so slow, like I‘ve the 250mbps but it’s always only until 30-50 when I run the speed test and it’s been months! Or almost a year now. This is so bad! I’ve done all the instructions like troubleshooting etc. still it’s the same. Tonight, it’s worst! No internet at all! Come on O2, this isn’t fair!edit o2_Gerrit 10.07.2025 moved to English O₂ Community: Broadband & Landline

I bought a o2 prepaid M sim for 14,99 euros and activated it on 6th oct 2025 (its says 14,99 euro/4 weeks). Its been more than a month now and my sim is still working and it shows Mein Guthaben: 14,71 €. I am confused...what I have to do, do I have to top up or its a postpaid thing. my tarrif: o2 Loop - 9 cents (Pay now via bank account and get extra GB)EU roaming (Speed Plus)
