Hello,My mobile internet has been severely throttled to a slow crawl for 3 months across all apps, whether I force 4G/LTE or use 5G on my Samsung Galaxy S24. My device settings are completely fine, APN is set to 'o2 internet', and my data volume is completely untouched.I was locked out of the website due to a security firewall/cookie issue, but I am now reporting this via Wi-Fi. Because the issue follows me everywhere, it is clearly not a local cell tower failure, but a system-side profile glitch in your internal database (Aktivierungshänger des Datenprofils).Could an o2 moderator please check my contract profile in the backend database, release any stuck data caps, and trigger a fresh HLR-Reset / SIM-Reset on network level?

Hello. I noticed an unwanted subscription 'O2 Unlimited Games Premium' on my account, which I never purchased or authorized. Could a moderator please cancel this service and issue a full refund for this charge? Thank you.

Hello everyone,I recently purchased a new O2 SIM in Germany and successfully activated it. I received a confirmation message stating that my SIM was activated. However, I still need to download and install my eSIM profile on my device to complete the setup.The problem is that, when I try to download the eSIM profile, I am asked to verify my identity by receiving an SMS. Since the eSIM profile has not yet been installed on my device, I am unable to receive the SMS required to complete the installation.This has left me stuck in a loop: I need the eSIM profile installed to receive SMS messages, but I need to receive an SMS to download the eSIM profile.Could someone please guide me on how to resolve this issue? Is there an alternative way to verify my identity or activate the eSIM profile without SMS verification? Any help or advice would be greatly appreciated.Thank you in advance for your support!

Hello O2 Team,I bought a new O2 Prepaid SIM card on October 12, 2026, and topped up €10 with the expectation of activating the 20GB data option.However, after using 1 GB, my internet stopped working. It seems standard pay-as-you-go rates were charged instead of booking the 20GB pack, leaving my credit balance at €3.64.Could an O2 moderator please check my account and help set up the 20GB data package or apply a goodwill credit adjustment?Thank you!

I activated an O2. Unlimited Trial SIM, but my speed is locked at exactly 1 Mbps on both LTE and 5G. I have full signal bars and manually configured the correct APN settings, but nothing changes. Could an O2 moderator please check my contract status and perform an internal Profil-Reset / SIM-Reset?

I currently have an unlimited data on demand contract. After my daily allowance of 10GB ends I'm unable to top up high speed internet by sending the SMS “WEITER” to 80112. I have tried switching my phone on and and off, taking the sim card out and putting it back in, and turning airplane mode on and off but nothing works. This has been happening for the last 2 days in a row. Does anyone have a solution? Thanks!

I got scammed by this guy who was at O2 shop Am Harras. First of all he was extremely disrespectful towards me for no reason. I went to the shop in January to get my contract extended, I was enquiring about different offers, the guy was not cordial at all to inform what offers are cost effective. Anyhow, I got my contract extended and he asked me to sign the contract. While I was about to leave he told me that you get this free sim card. I didnt need it but he asked to keep it and I just put it in my bag. Today When I checked my invoice I was charged 73 euros. When I called customer care to enquire about why I was charged so much, I got to know that there are two contracts active on my profile. I had no idea about it. WHEN I WENT TO SHOP I WAS TOLD THAT YOUR CONTRACT IS EXTENDED AND WAS NOT INFORMED THAT HE IS MAKING ANOTHER CONTRACT IN MY NAME. THIS IS A FRAUD, I REQUEST TO IMMEDIATELY CANCEL MY SECOND CONTRACT AND REFUND MY MONEY.I have a feeling this guy did it INTENTIONALY and it i

Hello, I need some help in English as I cannot navigate the German hotlines.My O₂ Prepaid M package expires tomorrow, October 13th at 14:58. However, my number transfer to SIMon mobile is scheduled for Wednesday, October 14th. My city registration/anmeldung is also on the same date, 13th around the time when my O2 prepaid will end. Is it possible to just extend this until the end of the day, for a few more hours? I do have 15GB left over in my plan.Can a moderator please activate the legal "Weiterversorgung" (continued service bridge) for Tuesday afternoon through Wednesday morning so that my mobile data and network connection stay active until the transfer? I do not want my current plan to auto-renew for a full month just for a few hours of overlap. Thank you!
