Ich verstehe Deutsch, kein problem. :-)
Sorry, my fault. I didn't read the whole text, which states it clearly. The available pictures are probably rendered, so they don't show 2 signal strength icons (which indicates a phone is dual sim).
According to the CPU speed, I would bet it has an MTK6516 chipset, the same one as all the Chinese clones. It is usable, but there is no 3D and the performance is poor. But if you don't plan to use the advanced phone functions heavily, it might be a good choice, especially for that price.
