Hello O2 Team,urgent Matter here: My 2 Multisimcard are not functioning as i have just tried to insert them today. I purchase the phone last April 1,2025 and they said everything was okay. In addition my previous contract is up to May 3,2025 only. So we badly needed this tommorow. The iphone has the e.sim and functioning well, but the other 2 sim cards has no signal and cannot call other numbers and we put it on to the other two phones. Please kindly informed the solution asap. ThanksSincerely,Ramil

Hello! 1 months ago to buy phone with monthly payment from O2 I went to O2 in Friedrichstrasse Berlin. He applied for the phone and made me a sim card contract my phone application rejected so I wanted to cancel the contract in the same day. He took back my contract and sim card and he said he send cancellation request and give me a document written by hand. I didn’t trust the guy so I requested cancellation by myself as well and I got a e mail that says it processed. But today I have got a bill 20 euros from O2 that the number which I don’t have possession. What should I do right now? Should I sue O2 to get cancellation from a sim card that I don’t have? Why they are not just cancel? 

Dear O2 Support Team,I am writing to report a serious issue with my mobile internet connection. Despite being on a contract with a speed of up to 300 Mbit/s, I am currently experiencing download speeds of only 3.17 Mbit/s and upload speeds of 514 Kbit/s, as shown in the attached screenshot from a recent speed test.This issue persists whether I am connected to 5G or 4G. I have tested both options and the speed remains equally low.My address is:Langbürgener Straße, 81549 MünchenI chose this plan specifically because I rely on a stable and fast internet connection. Given the current situation, I am unable to use the internet as needed.Could you please urgently check if there are any network issues in my area or with my connection

Hi,I canceled my contract and kept waiting for the instruction on return of the router. I never received any instructions for the return through email or by post. This month I received a bill of 86.25 Euros stating "Compensation for non-returned rental devices". The router has been lying packed in the box for the whole period. How could I return it without the instructions? After the bill, while creating this issue, I found the link of "self return portal" on this forum. I already did this process and today I sent the router back.I request you to return of my deducted money.Thanks.

Hi,Is anyone else having problems with internet? I don‘t have a proper internet connection since about 3 months. The power LED starts to blink all the time and I lose my connection and honestly I am very frustrated with this. They switched my router, I had to buy a new sim card for €15 and I still don‘t get a good internet connection.edit o2_Gerrit 03.05.2025 moved to English O₂ Community: Mobile

I lost my phone recently and I want to get a replacement sim card but I didn’t do the full registration in my O2 app to actually order a replacement sim. Can anyone help please?

I have had so much difficutly and frustration with O2. After waiting 3 weeks for the “fastest” shipping, my router arrived. I tried to set it up and checked with my landlady who ended up telling me that a cable connected router doesn’t event work with my apartment. I need to get a 5G/LTE wifi setup. Now I need to return and cancel the Fritzbox that was sent to me and order the correct 5G home wifi setup. Not even going to go into my concerns about getting properly refunded for ordering the incorrect router yet.Changing my O2 tariff has actually been impossible.I get stuck on the shopping cart page when I try to move forward to pay for the new setup. I have tried on my phone and on my laptop. Neither work. Next I tried to login into my O2 to change the “tarif” and select the 5G option. The website has a seizure and gets frozen in a loading state. What is going on?? I’ve never experienced so much difficulty trying to set up a simple

Hello, I really need some assistance here. I just undertook a contract with o2 for Internet, and when inputting everything into my FritzBox 7590 AX, the DSL connection will not work.I had the same problem with another supplier, so am sure its the DSL line problem, and not the supplier.I am 100% sure everything is connected properly, and the connection box in the basement looks to be fine, from the limited research I did. My hausmeister said to contact o2, but if anyone has any suggestions what the possible issues are, what the general next steps are, or how to go about it, I’d really appreciate it.edit o2_Gerrit 02.05.2025 moved to English O₂ Community: Broadband & Landline

Hi, I have Free M Boost online contract and have been customer since Aug 2018. Can I receive any benefits in purchasing phone through O2. I am interested in Xiaomi Redmi Note 14 5G.

So I order my first e-sim thinking that it would arrive via email, instead of by post. Given my circumstances that I haven’t arrived in Germany yet, I had no idea. Thus, I made my second order thinking it might be a system error.  Once I’ve arrived, I saw in my mailbox that I have received two! I immediately went to the closest O2 shop to cancel the second order. They did, and affirm me that I won’t receive charges. Since the e-sim was never activated no longer than 14 days. Fair enough.  Just as I thought this is behind me now. I received the bill of two numbers still! I called the customer service, they said they will inform me after discussion with their within 24 hours. Sadly I never heard from them again, nor I can find a customer service email.  What can I do :) 

Hi Friends,Yesterday I took the extension for my new contract from the o2 store and They give me a new plan it cost 27.60 euro per month only for my sim card.I ask the guy is there any plan that cost less than this and he told me that you can either keep the same plan or took new plan of 27.60 per month with unlimited internet.After I discus this with my friends they told me that there is other plan with low cost and also I checked my o2 app I realized that I get cheated with this o2 shop guy. So what I do to cancel my contract or is it possible?Edit o2_Kathi 25.04.25 Title adapted for a better overview

Hi everyone,I really need advice. I ordered an O2 eSIM online but missed the confirmation email (because it was in German and I don’t speak German yet).Since I didn’t receive or activate anything, I thought the order was canceled or didn’t work. An hour after that, I went to an O2 shop in person and signed up for a contract there, thinking it was my only one. After that, I got some emails from O2, but I assumed they were just about the shop contract. I didn’t check the O2 app at all — until the first bill came — and then I realized I actually have two phone numbers and two contracts! I tried to cancel everywhere (hotline, chat, email), but they told me nothing can be done after 14 days.The problem is: I never even installed or activated the eSIM on my phone. I can’t afford to pay for two contracts at the same time. Is there anything I can still do? Maybe an “außerordentliche Kündigung” (special cancellation

I can't take it anymore.Since December 2024, I’ve been having internet issues, and things are only getting worse.It’s reached a boiling point – I can’t attend Zoom classes properly, I can’t watch videos without massive delays and lags.For the past two months, I’ve been fed empty promises that something is being fixed, and that I would get a refund – but I still haven’t received anything.I had been using mobile internet for a year and a half without any problems – everything worked perfectly.But unfortunately, at a very important moment for me – during exam preparation – the situation has become a disaster. This ruins all the previous good experience.I can no longer say that O2 is a reliable internet provider.O2 is not a reliable internet provider – and that’s really disappointing.Can you please finally fix the situation?My contract with

Hi all,The cable internet was not working now. I have been with cable internet for more than 22 months. I have followed the process by removing the power cord and switching on the router 6660. The power and the Wlan light stays on but there is no internet. I called the o2 holiness and they said they would arrange a technician, but no one turned up. Could anyone here help?

I recently ended my contract and was informed that my number has been released for transfer. However, due to unforeseen delays, my new service provider was unable to complete the porting process in time.Can you extend the retention period for my number to allow the transfer to be completed? I would greatly appreciate your assistance in holding the number for a little longer so that I do not lose it.Please let me know if any additional information or action is required from my side.

Hi,I signed a contract in the O2 Shop yesterday. Only to realise when I got home that the attendant actually wrote the email down as gmaill (with 2 Ls).The rest of the email is written correctly (the same as I used for this account). I would like to correct that if possible.Best Regards

Hi everyone,I hope someone here can help or share their experience.I had the o2 my Home L contract with 100 Mbit download speed and used a FRITZ! Box 6660 Cable router.I canceled this contract on 21.04.2025 and ordered a new contract (o2 Home XL, 500 Mbit), which was supposed to start today (22.04.2025) — using the same router as before.However, after restarting the router and checking the connection, I still receive only 100 Mbit download speed, the same as with the old contract.My questions: Is it normal that the speed upgrade takes a few more days after the new contract start date? Do I need to do anything on my side (like reset the router to factory settings or contact support)? How can I check if the new contract is already active on my line?
