When does my mobile service actually end?

Your contract ends at the next valid cancellation date after your notice period. For 24-month contracts the notice period is 1 month before the contract end date. Once the minimum term has expired you can cancel monthly with 1 month's notice.

Can I withdraw my cancellation if I change my mind?

Yes. You can withdraw a submitted cancellation via the 1&1 Control Center or by calling customer service up to four weeks before the contract end date.

Are there early termination fees?

No. 1&1 does not charge early termination fees for standard mobile contracts cancelled at the regular end date. If you cancel mid-term (Sonderkündigung) due to a price increase or service failure, no fees apply either.

What happens to my 1&1 email address after cancellation?

Limited access to your 1&1 email account remains available for a period after the contract ends, but you will no longer be able to change your password. It is recommended to migrate or forward emails before the contract terminates.

Can I keep my mobile phone number when leaving 1&1?

Yes. You can port your number to your new provider. Request the number porting (Rufnummernmitnahme) directly with your new carrier before cancelling with 1&1 — the port itself triggers the termination of the old contract.

What if I miss the cancellation deadline?

If the minimum contract term has already expired, you can cancel at any time with 1 month's notice — the contract simply continues on a rolling monthly basis. If you are still within the minimum term and miss the deadline, the contract auto-renews and you must cancel again for the next period.
