We score every German prepaid plan on five dimensions: price per gigabyte, annualised cost (4-week tariffs renew 13 times/year), 5G availability, host network, and EU fair-use cap. Prices verified May 13, 2026. Network scores from connect Netztest 2025, Opensignal Germany Q1 2026, and the Bundesnetzagentur coverage register.
Coincidence isn't the reason — it's the market clearing price for 25 GB on a 4-week cycle. The supermarket chains all source from the same three networks (Telekom, Vodafone, O2) and Drillisch acts as the white-label MVNO behind several. Once one brand priced 25 GB at €8.99/4w, the others followed.
Headline price yes, true annual cost no. A €8.99 4-week tariff renews 13 times per year — that's €116.87/year. A €9.99 monthly tariff is €119.88/year. So 4-week tariffs at €8.99 actually save you €3/year vs. monthly at €9.99 — small but real.
Pick one with same-day activation: Vodafone CallYa eSIM (VideoIdent, ~20 minutes), O2 Prepaid eSIM, or any supermarket SIM with the SIM card itself bought at the store. ID verification (passport scan or VideoIdent) is required by German law before activation.
Some do. Vodafone CallYa, O2, LIDL Connect, ja! mobil, Penny Mobil, and Lebara all advertise prepaid eSIM. Telekom prepaid eSIM is partly available but not on every tariff. Supermarket brand eSIM swaps usually require a one-time SMS code from an already active SIM, which is a friction point for new customers.
