Also a strong fit

Same eligibility, a different shop or network. Every plan is in the full market overview.

This ranking reaches the same winner as the general one. It wins on both weightings, so the change shows up further down the order: Ease of buying moves from 30% to 50% and Coverage moves from 25% to 10%.

Only plans with a seven-day validity window are ranked here: a 3-day plan strands you on day four, and a 30-day plan makes you pay for three weeks you will not use. The under-two-weeks page ranks the longer windows.

How we ranked this for one-week visitors5 criteria, weights published

A reader we describe as one-week visitors is not the average reader, so this page does not use the average weights. Ease of buying carries 50% here against 30% on the general ranking, and Coverage carries 10% here against 25% on the general ranking. The weights were fixed on 17 August 2026, before the prices were collected.

What is ruled out, and why

A blocker is not a drawback. It is something that makes the product unbuyable for this reader, and it caps the score at 1.0 however good the tariff is otherwise.

What one week of data actually costs

The seven-day ladder, as of August 2026: Saily 1 GB for EUR 3.47, Nomad 1 GB across 35 European countries for EUR 4.73, Airalo 3 GB for EUR 6.88, 5 GB for EUR 9.03 and 10 GB for EUR 12.90. If you refuse to count gigabytes, Ubigi sells unlimited Europe data for EUR 23 and Holafly for EUR 23.65, both over exactly seven days.

For a week, 3 GB covers maps, messaging and photo uploads; streaming video is what pushes you to 5 or 10 GB. Every plan here activates by QR code in about two minutes, works on any unlocked eSIM phone, and needs no identity check, because none of them carries a German number.

That last point is the one thing to plan around: these plans are data only. WhatsApp calls work; a text from a bank does not arrive. Staying past a couple of weeks, or need a German number? Take the under-two-weeks plans or the short-stay ranking instead.

The same tariffs, ranked for other readers

Every persona page ranks the same catalogue. Only the weights differ, and each page states its own. If you are already down to two tariffs, the full market overview puts every named tier side by side on price, data and EUR per GB.

How we compared these

Five criteria, weighted for this reader and published above, fixed on 17 August 2026 before the prices were collected. Every price comes from the provider's own page, dated in the catalogue. A blocker caps a product at 1.0. Unlimited allowances are capped at 200 GB when calculating EUR per GB, or every unlimited plan would win that column automatically.

One limit worth stating: the catalogue carries one fit score per persona, not a score per criterion, so the ordering reflects that score and the editorial reasoning behind it rather than an arithmetic weighted total. Per-criterion scoring is the next data pass; until it lands, the weights explain the ranking rather than compute it.

Of the 23 plans in the catalogue, 14 score 4 or 5 for this reader, across 8 providers. Where fewer than three providers clear that line, the third card is still the next best option available and is labelled for what it wins on, not presented as a strong fit.

Sources: provider tariff pages and dated German price sources, accessed August 2026. Some links earn a commission at the same rate for every provider, so no weighting favours a payer.

Frequently asked questions

How much does an eSIM for one week in Germany cost?

EUR 3.47 to EUR 12.90 as of August 2026, all over seven-day windows: Saily 1 GB at EUR 3.47, Airalo 3 GB at EUR 6.88, 5 GB at EUR 9.03 and 10 GB at EUR 12.90. Unlimited data for the week is EUR 23 at Ubigi and EUR 23.65 at Holafly.

How much data do I need for a week in Germany?

About 3 GB covers maps, messaging, search and photo uploads for a normal tourist week. Streaming video is the multiplier: with daily streaming, take 5 to 10 GB. Hotel and cafe Wi-Fi is widespread in German cities, which keeps most visitors under 3 GB.

Should I buy a German prepaid SIM instead for one week?

Usually not. A German prepaid SIM requires a starter kit and a passport identity check (VideoIdent) before it activates, and the typical bundle runs a 28-day cycle, four times your stay. It only wins if you must receive SMS on a German number, for example for a German bank account.
