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,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. 

I came back from a trip abroad, in which I used another sim with a local company.However i am being charged 60 euro for using my internet outside of the eu.

I live in Munich, and I am fortunate to have excellent reception conditions of O2 5G network. I decided to use O2’s unlimited home internet service based on a SIM card."And now I have a serious and persistent problem with my home  sationary  5G acses point ( TP-Link DECO X50  5g  (HW 2) ) internet service whit O2 SIM card. From the very beginning, I experienced minor difficulties when using multiple devices at home. However, the situation has significantly worsened: I currently have around 10 devices connected, and the internet has become almost unusable.Whenever any medium-demand activity occurs on any device, the entire household experiences a complete slowdown. For example: Opening any website with multiple connections or heavy advertisements often causes the internet to fail for all users.

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

Hello,I speak English, so I hope it’s okay to write in English.I recently ordered a new prepaid SIM (monthly cancellable) from O₂. I received an email saying that the SIM card was handed over to the post about a week ago, but I still haven’t received it.I realized that I missed the building number in my address when placing the order. There is also no tracking ID, so I cannot check where the shipment is.Could you please advise:What should I do in this situation?How long should I wait before requesting a resend?Is it possible to update or correct my address now?I am an international student, and I urgently need a German phone number, so any support would be greatly appreciated.Thank you in advance!Edit o2_Antje: Moved from Prepaid to English Community / 10.11.2025

Hi. I have two separate contracts with o2. xxxxxxxxx207 and xxxxxxxxx366. I requested an extension for one of them (xxxxxxxxx207) on June 2nd. But both were renewed. I wanted to cancel one of them (xxxxxxxxx366) because I hadn't used it since ordering it about a year ago, but instead, even that one was renewed. So I had been losing money for a year and now I will lose money again until the end of this new contract, which I didn’t want and didn’t ask for.I had asked this on the live chat two weeks ago. But it was not helpful.Kindly help me resolve this issue. Moved to English: Mobile // 03.10.2025, 18:37 Uhr, o2_Rebecca
