SIM cards & mobile data
Get connected the moment you land with an eSIM, then move to a German SIM once you can register. Prepaid needs no Anmeldung; contract SIMs usually do.
eSIM for day one
A travel eSIM gives you data immediately, before you have a German address — handy for maps, appointments and calls on arrival.
Prepaid vs. contract
Prepaid SIMs (Aldi Talk, Lidl Connect, etc.) need no registered address and no Schufa. Cheaper monthly contracts usually require both.
