Germany eSIM, Prepaid SIM Cards & Wi-Fi Guide (2026): Telekom, Vodafone & O2 Coverage

Why travel eSIMs beat airport SIM kiosks in Germany (which require video ID passport verification), plus network coverage comparisons across DB ICE routes and the Alps.

Why a Travel eSIM Is Fastest in Germany

Under German telecommunications law (§172 TKG), buying a physical prepaid SIM card at a German supermarket (ALDI Talk, LIDL Connect) or Telekom/Vodafone shop requires mandatory passport identity verification (Postident or video ID call). Installing a pre-activated Germany/Europe travel eSIM (5 GB to 20 GB for €8–€22) before takeoff gives you instant 5G data upon landing at FRA, MUC, or BER with zero paperwork, and includes EU roaming if you hop across the border to Salzburg (Austria), Basel (Switzerland—check plan), or Strasbourg (France).
