1-month plansThe best deal is no use without signal. Check the network where you live, study and travel.
Plans by networkMost mobile providers don’t cut prices across the board. They add data for the same price, drop the connection fee or lower the monthly price for selected plans. On prepaid there is often a cheaper starter pack, extra starting credit or an annual pack with more data. The big networks add cashback or a switching bonus. Many deals start in early or mid November and end in early December.
If you are under 28, Telekom, Vodafone and O2 give you Young plans with more data or a lower price all year round. A Black Week deal is only worth it if its average per month is below the Young plan that suits you. Our comparison shows both side by side.
Black Week deals are usually for new customers. If your contract has passed its minimum term, you can cancel with one month’s notice and take your number with you. If you are still in your minimum term, ask your provider whether you can switch to the deal plan.
Black Friday is on Friday, 27 November 2026, Cyber Monday on 30 November. Mobile providers often start their Black Week deals in early November. Each card shows when the deal ends.
