Hi O2,     I'm currently having a mobile number, but I have my email registered before then I can't use this email to link my phone. Can you unregister my email? 

I prepaid for Roaming Plus World to cover my trip to Mexico, but for the last 2 days I have had no access to data. I received an SMS a week ago saying it was almost up and I'd have to buy more, but nothing since. I also can't add more via Meino2. I have also tried toggling to a different network and restarting. Please help! Edit o2_Kathi 29.10.25 Moved from the section Packs, Optionen & Ausland to English o2 Community

So I paid an amount of 75 euro that was showing outstanding amount on my o2 so I paid it on 15th of September but without a reference number directly to the o2 account usually its deducted automatically but since i had low balance it was credited back but I paid an amount of 75 euro in that day I already spoke with the customer service they tried to tell me to ask the Finance department but the problem was when I did try to talk the support person was not able to hear me. I've made multiple payments without the reference other seems to work but I don't understand how that 75 euro doesn't seems to please help me with the payment because of my o2 account it doesn't update my payment and then I get a monthly added payment together thats why my 75 euros is stuck somewhere (Rohan khatri (XXXXXXX DATUM 13.09.2025, 15.06 UHR ) this is the reference on my payment since I paid directly to the o2 account this was the reference but for other payments it worked but not this one o2_Giulia, 24.10.20

Yesterday I got home to find that someone who had stolen the apartment key months earlier had come into the apartment with the key and stolen the PlayStation 5 that I had had for about a week. Is there anything I can do besides reporting it to the police? o2_Giulia, 24.10.2025, 14:28: verschoben von Mobilfunk zu Hause & HomeSpot zu English O₂ Community

 I can't add my bank details for recharge my phone what is the solutionEdit o2_Bianca 16.10.25 09:06Uhr: Moved from o2 Prepaid to English o2 Community mobileEdit o2_Kathi 21.10.25 Title adapted for a better overview

Hey there! I had a little mishap and accidentally deleted my pre-installed eSIM. Any chance you could help me get a replacement QR code so I can set up my “my O2” account?

I have already ordered new iPhone 17 with contract on 08.10.2025 but still no further information and not yet received what should I do to get information or status about ordered phone could you please answer me about that 

Over the last days my internet mobile data are ridiculously low causing me stress as cannot do basic things that I pay quite high price to doi have been an O2 costumer for quite a few years already and this behaviour is unacceptable.I suspect you don't on purpose to pay extra for higher speed suddenly as these types of text messages came from you instead of explaining why on earth I experience such low useless speed. Also , my contract of 40€ high speed home + mobile unlimited calls and internet was successfully paid and even several times exceeding 100€ per month as never understood why you charged some outrageous bills while using it few times for a while abroad. Now although my contract finished in September, I do continue to pay as I assume without interrupting it , should continue with same rates and terms - but what I experience is totally unacceptable.If it's not fixed by Monday the 13th October - I will switch to another more trustworthy provider as this should be denounced als
