Choose a Germany eSIM by matching the allowance to your trip length and expected use, then check the existing network table for phone compatibility. The page keeps its country-specific operator, band and median-speed information, while the sections below help you compare plan sizes and use the Bundesnetzagentur map for your route.
Start with the length of your stay, then allow for navigation, messaging, streaming and work use. A fixed-volume plan gives you one data pool across its stated validity period.
Best for: A short city or business visit where mobile data is mainly for maps and messages.
This is the smallest fixed-volume profile for a stay of up to seven days.
Usage tip: Use Wi-Fi for video, photo backups and app updates to keep more data available while you are out.
Best for: Trips of up to two weeks with regular navigation, messaging and light social-media use.
The 3 GB allowance remains available across the stated fifteen-day validity period.
Usage tip: Download maps before rail journeys or country drives and use mobile data for live directions.
Best for: Longer stays or travellers planning regular streaming, video calls or work-app use.
A larger thirty-day data pool gives heavier activities more room than the short-trip profiles.
Usage tip: Compare your normal phone usage with the available allowances and monitor usage during the trip.
Your eSIM roams onto Germany's own operators. These are the networks and the frequencies they run — check your phone supports them before you travel.

Germany has extensive rural and forested areas with no mobile service on any network; foreign phones often lack B20 (800 MHz) and B28 (700 MHz), which are critical for rural and indoor coverage.
The Bundesnetzagentur mobile monitoring map compares operator-specific outdoor 2G, 4G, 5G and 5G SA coverage. Use its operator and technology filters for your itinerary, then confirm the network details for the selected eSIM product.
Check the area around each hotel, apartment or work location. The regulator notes that building materials, device support and network load can make indoor experience differ from predicted outdoor coverage.
Use the map along the route as well as at the destination. Terrain and your phone's band support matter, so compare the device with B20 and B28 in the existing network table.
Check the selected product's country scope and the map for the exact location. For a route that continues into another country, compare the appropriate country plans with a regional Europe option before departure.
For broad compatibility, compare your phone with the 4G and 5G bands in the existing Germany network table. B20 and B28 are useful lower-frequency bands for wider-area and indoor coverage, while the listed mid-band frequencies add capacity in supported locations.
Keep the QR code and installation instructions available offline, and complete each step according to the selected product's instructions.
When validity starts: Validity-start rules can differ by product. Check the selected plan details before installation and travel.
