Do You Need a SIM Card for a One-Week Holiday in Germany? (2026)
The verdict for a one-week holiday
Not a physical one. Every German SIM, prepaid included, requires an identity check before it activates, VideoIdent with your passport, and the typical prepaid bundle runs a 28-day cycle, four times your stay. A travel eSIM installs by QR before you fly, needs no ID check, and covers the week from EUR 3.47. The one-week eSIM ranking has the plans.
Why the physical SIM loses a one-week trip
Germany requires identity verification on every line with a German number (TKG), prepaid off the supermarket shelf included. That means finding a starter kit, then a VideoIdent session with your passport, then minutes to hours of waiting before the SIM works. The reward is a bundle like ALDI TALK, 25 GB for EUR 8.99 per 28-day cycle: excellent value for a longer stay, but you fly home with three unused weeks on the clock.
The two real reasons to do it anyway: your phone has no eSIM support, or you need a German number that receives SMS, which a travel eSIM cannot do. For everything a holiday actually uses, maps, messaging, tickets, photos, a data-only eSIM is the right tool and the cheaper one.
Frequently asked questions
Can I buy a physical SIM card for one week in Germany?
Yes, but it is the slow option. Every German SIM, prepaid included, requires an identity check before it activates (VideoIdent with your passport), and the typical prepaid bundle runs a 28-day cycle, four times a one-week stay. A travel eSIM installs by QR before you fly, with no ID check, from EUR 3.47 for the week.
When is a physical German SIM worth it for a visitor?
When your phone does not support eSIM, or when you need a German number that can receive SMS, for example to verify a German bank account or receive delivery notifications. In both cases buy a prepaid starter kit (ALDI TALK, 25 GB for EUR 8.99 per 28-day cycle) and plan for the VideoIdent check on arrival.
What does one week of mobile data in Germany cost as an eSIM?
EUR 3.47 to EUR 12.90 as of August 2026 on seven-day windows: Saily 1 GB at EUR 3.47, Airalo 3 GB at EUR 6.88 and 10 GB at EUR 12.90. Unlimited for the week is EUR 23 at Ubigi.
