With O2, you can cancel your contract in various ways. We will show you the options and provide a cancellation letter for download.
Canceling your O2 mobile phone contract: Ways to cancel, notice periods, and conditions
At o2, you can find all the information you need about canceling your contract in your “My o2” customer account. You can also find out about the notice periods and conditions for cancellation in the comprehensive FAQs. As is often the case with 24-month contracts, a minimum term of usually 24 months applies here too.
- If your contract was automatically renewed after the minimum contract term expired, the Telecommunications Act (TKG) reform means that, as of December 1, 2021, you can cancel your contract with one month’s notice.
- Some older tariffs still stipulate a regular notice period of three months before they are extended. This corresponds to the previous standard.
- o2 itself points out that after the minimum contract term has expired, the contract can be terminated with only one month’s notice.
- By phone: You can initiate the cancellation by phone. Example number: 040 51 90 06 642. However, please check the current number and availability on the o2 website.
- By mail or fax: Send the cancellation letter to: Telefónica Germany GmbH & Co. OHG, Customer Service, 90345 Nuremberg, Germany, or by fax to, for example, 01805 571766.
- Online: In your “My o2” account or in the app, you can often mark the cancellation (“Mark cancellation”) and then confirm it by phone if necessary.
- Information on the contract term: In your original contract, the minimum contract term may be 24 months. If the cancellation period is missed, the contract is usually extended automatically – however, since the TKG reform, this is now only for one month and no longer for 12 months. Exceptions for special tariffs (e.g., “o2 Genion S without cell phone,” “o2 o,” and “o2 Blue Flex”) may have different notice periods – please check the exact tariff agreement here.
Legal changes, special termination rights & information on termination letters
Since the TKG reform came into force, many rights of mobile phone customers have improved. Anyone wishing to terminate their o2 contract should therefore be aware of the current legal regulations. Particularly important are the shortened notice periods after the minimum contract term has expired and special termination rights in the event of price changes or relocation. The form of the termination letter also plays a decisive role in ensuring that the termination of the contract is legally effective.
- Statutory notice period since the TKG reform: Contracts may continue to have a minimum contract term of up to 24 months. After this minimum term has expired, a three-month notice period is no longer mandatory—a one-month notice period applies, whereby providers must provide a “cancel button” or comparable electronic cancellation option in the event of automatic renewal.
- If the provider permanently fails to provide contractually agreed services (e.g., insufficient Internet bandwidth), you have a right to a reduction in price and termination.
- Special termination rights: Price increase by the provider: You may terminate the contract within three months of the change without observing the regular notice period. Moving abroad or to a location where the provider cannot provide the contractually guaranteed service (e.g., Internet: required bandwidth is not available). In this case, termination is possible with a notice period of one month. Death of the contract holder: Termination is usually possible (e.g., by heirs).
- Note: In the case of mobile phone contracts, a special right of termination, for example due to “no network,” is not usually automatically granted.
- Information in the letter of termination – what you should pay attention to: If you cancel in writing (by mail, fax, or online form), the following information must be included: your full name and address, customer number or contract number with o2, the SIM number or phone number of the contract (e.g., mobile phone number), the date the contract began or the minimum contract term (if known), and your request:
- “I hereby terminate my mobile phone contract with o2 at the earliest possible date,” if applicable, a note about transferring your phone number, your signature (for cancellations by mail or fax) or clear authentication for online cancellations, date and place of the cancellation notice.
- Further information:Remaining credit: If you have prepaid credit or vouchers, check the terms and conditions – credit may expire or be restricted at the end of the contract. Outstanding installment payments for devices: If you are paying for a cell phone or tablet in installments (“cell phone financing”) as part of your contract with o2, these installments are often still due after cancellation until the purchase is paid for in full.
- Returning hardware (e.g., routers, rental devices): For landline/internet contracts with a rental router, you may need to return the hardware to o2. If you fail to return it, o2 may demand compensation for the value.
Number portability from o2
If you would like to transfer your existing phone number to another provider at the end of your contract, please note the following:
- Transferring your number is generally possible – you can submit a porting request even during the contract period.
- Fee: o2 sometimes charges a fee for this – please check the current price in your contract or on the o2 website.
- Deadline: You should request porting as early as possible, especially if you want to switch at the end of your contract – this will ensure there are no or minimal gaps.
- Procedure: The new provider requests the porting, and o2 releases the number. Your old contract continues to run until it ends as normal – therefore, please note the examples with “termination on the end date.”
