Hello,I am currently using a ZTE_C128E0 router. However, the network connection is extremely unstable, and the speed is so slow that I can hardly use the internet at all. Could you please clarify what the cause of this problem is?There are 4 indicators in the router like that; battery: on, LAN icon: on, SMS: off, signal strength: blinking,As the internet is practically unusable, it is causing significant inconvenience. I kindly ask you to resolve this issue as quickly as possible.Thank you.

I have been going through problems with my O2 app for 3 weeks now. Firstly it started with me buying 20 euros of credit on the app and it didn’t reflect into my account. I tried to go fro the hotline, but without credit, they dont attend me. Not even in emails. Then I bought my credit in the supermarket, 15 euros, it reflected after two days, then I bought data but it didnt reflect and the credit dissapeared. I tried to go to the O2 hotline but they didnt help either. I have prepaid.How can I solve it?

Hi. I returned from holiday 2 days ago to find that the signal in my area is very poor. I can't watch videos or steam music, apps won't refresh and websites time out. I saw online that the is a problem with the transmitter in my area- postcode 81247. 1- Is there an estimated time that the transmitter/ station will be fixed? 2- can my unused data be transferred to the next month in my contract? I cannot use it as I had planned to do.   Edit by o2_Katja: Verschoben von Mobilfunknetz

Hi everyone,I’ve been an O2 customer for over two years and recently tried to switch from my O2 Unlimited Smart package to a smaller plan while keeping my old number. I was advised by a customer service representative, to get O2 Mobile M Flex Online (2024) (€14.99/month, €12 SIM, cancellable anytime), with the assurance that my number would be ported automatically.Unfortunately, the porting failed twice. Instructions from another officer were incorrect and didn’t work. While abroad, I sent multiple emails and WhatsApp messages but couldn’t reach support. To avoid losing my old O2 number, I extended it under O2 Mobile XS Flex (2024) and canceled the M Flex SIM, which didn’t serve its purpose.I have now received a bill for €67.38, which includes O2 my Data Unlimited (€39.99) and a connection fee. These charges were never agreed upon and were waived in my contract. Since the SIM wa

Hello, my second SIM card was blocked because I entered the wrong PIN code 3 times (I now have the correct one). I need to restore it, but I have lost my PUK code and I can't access my O2 account. I can't solve the problem through the hotline because I don't speak German. Can you help me?Tanks 🙏

I cannot top up the account , and have no connection at all even with prepaid pack activated. It says  Das Lastschriftverfahren ist aktuell nicht möglich. And won’t take money from my connected Sepa account

But the problem still remains. Edit o2_Kathi 22.08.25 Moved from the section o2 Mobilfunk: Rechnung to English o2 Community: Mobile + Title adapted for a better overview

Recently I had experienced what can only be described as the worst hotline customer service ever, that person straight up didn’t want to sell / help me with anything while I was the one telling them their job, and to my luck I had to deal with the same person 3 DIFFERENT TIMES all of which were horrendous.Now the thing that infuriate me the most is that I’m not receiving any SMSs anymore after the call to rate my experience, like where should I go with this?The number I want to receive these text messages on is (713) at the end

Hi! I can't activate my prepaid O2 card.I have already tried several times on the website: https://sim-aktivieren.o2online.de/.What happens is that, after I enter the “Call number,” the following message appears: Die angegebene Rufnummer ist nicht bekannt. Bitte überprüfen Sie Ihre Eingabe.This happens every time I try.

Dear O2 Support Team,I am writing to request assistance with an issue regarding a recent order I placed with O2.On Sunday, I ordered a mobile phone and a SIM card with a contract. I also made a first payment in response to the offer email I received from O2. Shortly after, I received a confirmation email stating that my order had been approved.Later in the week, I received another email asking me to confirm my email address by logging into my account. However, I have been unable to log in or complete the confirmation. The system asks for a user ID, contract number, or phone number, but none of the information I enter is recognized — most likely because I never received a contract, SIM card, or phone number.To add to the confusion, I received another email saying that my My-Handy order had been rejected and that my payment would be reimbursed. However, I then received yet another email again asking me to confirm my email address — which I still ca

1. What are third-party services?These are extra services charged through your invoice but provided by other companies or your mobile provider. Examples include ringtones, games, chat services, prize draws, or streaming subscriptions.2. Why can they be a problem?Many people sign up without realizing it (e.g., by tapping on ads or pop-ups). The costs often only show up later on your phone bill. Cancelling can be tricky, since the contract is with the third-party provider, not your mobile company.3. How to cancelContact the third-party provider directly (details are usually on your bill or in a text message). Ask our customer service for help. They must give you the provider’s contact details and support you with the cancellation. If you subscribed a service of O₂First of all, you should cancel the subscription within 14 days notice.
