The Negative at the beginning: is totally inadequate describes how and where you have to insert the SIM card. I have it stupidly attempted to manage the then resides within the stick disappeared, whereupon the stick had to be broken with a small SIM. The regular-sized SIM was then fitted, after I had tried all variants of introduction - required would be a small graphic that shows the position of the bent corner of the SIM, if not in the stick but then at least in the user manual (helpful hint there: Insert the SIM at the designated location in the stick a - sincere thanks for this great advice ...) - it thus penalized.
Otherwise the drive will also work with Aldi Talk. (To be sure, the included software not ALDI-Talk capability. Tariffs and flat rate so you need to book before with any other unit, but after that can also surf the Telekom stick on Aldi resp. E-Plus).
So overall an Internet Stick, which does what it should.
