Germany's mobile networks — Deutsche Telekom, Vodafone Germany, and O2/Telefónica — blanket all 16 states with strong 4G/LTE and fast-growing 5G in Berlin, Munich, Hamburg, Frankfurt, Cologne, and the ICE rail corridor. A Germany eSIM activates at Frankfurt (FRA), Munich (MUC), or Berlin Brandenburg and keeps you online through the S-Bahn, on long-haul Autobahn drives, and in the smaller Bavarian or Black Forest villages where free Wi-Fi is thin. Most regional eSIM plans include EU-wide roaming at no extra cost.
