1&1 Germany SIM card: we found no prepaid tariff for visitors

Is a 1&1 Germany SIM card a good choice for a visitor?

Probably not for a holiday. When we searched 1&1's mobile site on 8 October 2026 we found no prepaid tariffs. What it sells are contract tariffs, including ones with a one-month notice period, and a SIM that comes as a triple-format card or an eSIM. A visitor staying a week has no use for that. Someone living in Germany for several months might.

What does 1&1 actually sell?

According to 1&1's site, its All-Net-Flat tariffs start from 9.99 euros a month as an introductory offer for the first three months, then 14.99 euros for 50 GB or 19.99 euros for 150 GB, and unlimited-data tariffs sit above that. It labels some tariffs as having no minimum term, with one month's notice. Prices and offers change, so check the tariff page before you decide. We are quoting these only as the figures shown in the search listing of 1&1's pages that day.

The eSIM is offered free with a contract, and 1&1 says activation can be done within three minutes with no postal delivery. The pages we read do not say what identification or German address a contract needs, and do not mention visitors at all.

What does 1&1 say about its network?

On its coverage page 1&1 claims about 95 percent 5G coverage across Germany in early 2026, with a goal of nearly 100 percent by the end of 2026. Where its own 5G is missing it says you are normally on LTE, and that almost everywhere in Germany you get at least a 4G signal.

One detail matters for how to read those claims. 1&1 notes that in areas not yet covered by its own network it uses national roaming on Vodafone's network, and that a connect rating it cites takes that into account. In other words, the experience depends on where you are, and you should look at 1&1's network check for your route. We did not find an independent comparison on 1&1's site and are not making one.

1&1 versus a prepaid or travel eSIM

If you want a German number for a visit, a prepaid SIM from Deutsche Telekom, Vodafone or O2 is the more usual route, though all need identity checks. A travel eSIM bought before you fly avoids that and works on an unlocked phone. We compare the options on the Germany comparison page.
