Germany's cities have strong 4G and 5G, but the country is famous among its own residents for Funklöcher — dead zones — on trains and in rural areas. If you expect to work on an ICE train or rely on maps in the countryside, plan for gaps.
Short answer: a 5–10GB Germany plan with validity covering your trip suits most visitors. Download tickets and offline maps before long train rides, and don't schedule important video calls on the train.
What a Germany eSIM costs
At the time of writing (October 2026), Wanderly's Germany plans start at $2.99 for 1GB, with 10GB for 30 days around $8. The median across data-only Germany plans is about $0.80 per GB — well under the $1.43 median across 187 countries in the Wanderly eSIM Price Index. Full options on the pricing page.
Some of the cheapest per-GB bundles last only a few days. The 10GB/30-day option suits most trips of one to three weeks.

Germany on a multi-country trip
Germany borders nine countries. Heading to Austria, the Netherlands, France or Switzerland? A Europe bundle can be simpler — but Switzerland is outside the EU and not every bundle includes it. See the best eSIM for Europe and the best eSIM for Switzerland.
