Hello,I have a mobile plan with O2 (around €45/month for 2 SIM cards), which is supposed to provide high-speed internet access.However, I am only getting around 15–20 Mbps, while two of my colleagues with similar plans and similar pricing are achieving 300–385 Mbps.I have already tried the following:Restarting my device Testing the SIM card in another phone Changing locations within the cityUnfortunately, the speed remains consistently low.I would kindly ask you to check my line or SIM configuration, as there may be an issue such as throttling, incorrect provisioning, or network assignment.Thank you in advance for your support.

i am on a business trip in Germany these days and my o2 number had no signal at all. It seemed the number was blocked by the o2 system. I activated this number in China before I boarded the plane. Can anybody help me solve this problem?Edit o2_Paul: Category change

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

Hi, I made a bank transfer with all the details provided on October 25th and the 20 euro have still not been credited to my account. I had to go to o2 shop to top up another 20 since my month is about to renew. I would like to know where my transferred money is, if I will get it back in my account or if it will eventually show up on my balance on o2. Can you please help me track this transaction, or give me some guidance in regards to it?Thanks! Edit: Moved to our english community, o2 Michi 30.10.22, 18:32

It seems there is a fraud/scam happening right now with O2 users. Recently I received an SMS about this Fightclub stuff and I never paid attention to it nor click the link. I ignored it and then next is that it already sent me welcome message. I still ignored it because I know it is a fraud/scam message. I did not worry because I did not do anything. To my surprise, I was already charged a membership fee not only 1 but 4 times. That easy, my account has been compromised and was charged directly. I felt the security level is a weak and to me it is very ALARMING!!!!!!!! I reported right away to O2 via email. They have not responded yet. Let see how it goes. I requested for a refund as well because this is a clear weakness in the security.07.03.2026 verschoben von o2_Katja aus Mobilfunkrechnung

Hello, I am writing to report an issue that has been occurring repeatedly with my mobile plan. Each time I have been in Spain, I have been charged approximately 5–10€ for connection and service fees. However, my mobile plan includes roaming within the EU, so these charges should not apply. This issue has been happening consistently since at least December 2025. I would appreciate it if you could review my account and refund all incorrectly charged amounts related to these incidents.

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 me that I have to

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 

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
