ETravelSim does not provide a true unlimited data eSIM for Germany. The plans that use “Unlimited” in their name give a fixed allowance of 4GB/day; once this limit is reached the speed drops to 128 kbps, which means data usage is still capped and the connection is throttled.
Instead, ETravelSim offers fixed‑data plans that allow full‑speed data until the allotted amount is used. For example, 4GB/day plans are available for 5 to 30 days, priced between $11.16 and $65.00, and a 50GB plan for 30 days is available at $29.19 or $49.99. These options may be more cost‑effective for travelers who need larger amounts of high‑speed data.
