And I want to reverse the operation, go on with O2 but since process started, my O2 number will be closed, is it a way to cancel it. I already cancel the operation from other supplier but I also need to inform O2 to take action and not closeedit o2_Gerrit 22.04.2026 moved to English O₂ Community: Mobile

Hello, I am planning to order a SIM-only home internet contract (around 50 Mbps for €14/month). Before ordering, I would like to clarify a few points: If DSL or fiber becomes available at my address later, will I be able to cancel the SIM contract before the 24-month minimum term? If yes, what would be the cost? Is there any option to switch (transfer) from the SIM contract to a DSL or fiber contract? If yes, are there any fees for this change? At the moment, I have checked and DSL/fiber is not available at my address that is in Dresden.   Edit o2_Kathi 22.04.26 Moved from the section o2 Mobilfunk to English o2 Community

hello im a student 19 living in Germany for university. i signed a contract for unlimited data last year on june for 30 euros a month .i got a call during august of last year and the caller told me since i was a loyal customer they would reduce my plan to 20 euros.

Hello everyone, I have been scammed by someone from o2. On 03/16/2026 i have received a call from employee from o2 that said that my contract has expired and he have offered me since i was a member since 2023 to renew my contract with some benefits like that my monthly payment is going to be 26 euros and i will have 100GB. On the very next month when i was checking my banking application i saw that i have been charged for almost 46 euros, or course i have called o2 to look for my rights and the employee there said that he spoke with his ' 'Administrator ' ' and everything has been taken care of. He said that I will receive an information regarding the situation but I didn't receive anything. Couple of day ago I called again to see what is going on why nothing has been changed, I have explained the whole situation like I am now for 4th time and nobody gave me any information. I asked the lady that I spoke the last time to tell me what is going to happened and she told m

Hello, I have two sim contracts:A) sim contract unlimited 5G (no public IP), which I am using as a hotspot for my laptop when I’m abroadB) sim contract unlimited 5G (with public IP, activation paid, and APN set on netpublic), that I am using to host a remote VPN service. On B, which has a dynamic public IP address, I set up a DDNS service that works perfectly. Periodically, my DNS name gets updated as expected with the public IP that the router receives via DHCP. If I am using A, I can't connect to my service and cannot even ping the router. Device A has no public IP address, but it gets an IP address from the cell like 10.178.7.176, and an external one like 176.2.66.7. The same service I host on connection B can work just fine from other connections that are not from O2. For example, I tried other mobile connections of other ISPs, and I could both ping router B and connect to my VPN service.

I had been using standard O2 monthly plan for €29.9.Additional €20 was deducted towards Mobile Business Engine Gmbh services for the month of  March,2026. So neither I know about them nor I had used any of their services. And without my consent this was deducted and  would request for cancelation of the so called services and would request your help in recovering the debited amount. Edit o2_Kathi 17.04.26 Moved from the section Digitales Wohnzimmer to English o2 Community

I've moved abroad from Germany in February. Right after, I've notified O2 online and provided the required documents.O2 cancelled my line, but not my wive's, which is under the same contract. I've sent a new request and provided the required papers again, but nothing happened and I'm still being charged.I'd like to see it solved right away. edit o2_Manga: veschoben von o2 Mobilfunk: Vertrag & Tarife zu Englisch: MobileEdit: converted to question // o2_Rebecca, 07.04.2026 15:26 Uhr

I want to leave O2 please help!!!

I would like to report that my mobile phone was stolen on 11 April in Germany. It's under contract with o2. I have already blocked my SIM card and obtained a police report regarding the incident.However, I am unable to find an option on your website to report the theft. Since I do not speak German, I am also unable to contact English speaking customer support by phone.Could you please guide me on how to officially report the stolen device and advise me on the next steps? I would also like to know how I can proceed with an insurance claim, if applicable. Edit o2_Kathi 14.04.26 Moved from the section o2 my Handy to English o2 Community

The free headphones with nothingphone 3 did not arrive. What to do?

I've moved from the EU to Latin America. O2 doesn't offer services here, so I want to cancel my contract. I've sent two letters to terminate it. The first was on September 11th. I received an email saying it was under review, and in October I received another bill even more expensive cause of a roaming I didn’t use cause as fast as I landed I turned off the data. I sent another letter and again received a notification that it was under review, but no confirmation. I'd like to know who I can contact remotely, preferably in English. I've sent emails and haven't received a response. The last time I contacted them, they said they couldn't find any cancellation letter. I no longer have my SIM card, so I can't make calls without incurring exorbitant costs, which is why I'm communicating via email. When I signed up for the prepaid SIM, I was told I could cancel at any time. I always get the option to end my contract in my O2 page but I can't find where.

Hello, I need help with my O2 prepaid S plan (€9.99 / 12 GB). For one month, my internet has not been working at all, even though my SEPA payment was successful and I can still make calls and send SMS.I have checked my APN settings (set to internet), restarted my phone many times and toggled roaming, but nothing works. When I dial *105#, it says ‘service not available’. It seems there is a technical block on my data profile. Could a moderator please suggest some solutions?

Hello,I am using an O2 prepaid SIM with the O2 S Pack.Please disable any automatic data recharge or automatic data pack (such as 1GB for 3.99€).I do not want any automatic activation of additional data when my current data is used.I prefer to manually choose and activate a new pack (for example upgrading to O2 M Pack when needed).Please confirm once this is disabled.Thank you.Regards,Sivasankaredit o2_Gerrit 12.04.2026 moved to English O₂ Community: Mobile

Hi everyone,I have a question regarding O2 in Germany.I have two contracts with O2 (one for my phone plan and one for a device installment plan). I made a payment of €65, but I used the wrong reference number (Verwendungszweck), so the payment was assigned to the wrong contract.Has anyone had a similar situation?Does O2 automatically transfer the payment to the correct contract, or do I need to contact customer support?I tried using their chat, but the bot keeps looping and I can't reach a real agent.Thanks in advance for any help!edit o2_Solveig April 7, 2026, 4:38 p.m. Moved from o2 Mobilfunk -> to English o2 Community
