I brought O2 prepaid sim card online 1 week ago. I tried to activate through Video-Ident and they did not accept my Indian Passport (also my German residence Permit was not sufficient) and asked me to approach the Deutsche Post. The Deutsche Post person tried to identify my passport but the machine did not accept it. Then I tried the two O2 shops in zähringerplatz and kanzleistrasse konstanz and they said they cannot activate a sim card that is bought online. They also told to buy a SIM card from their shop which they could activate and that cost 25 Euros compared to the 10 Euro card I have ordered online !
So as an Indian in Germany I cannot identify myself and use the O2 sim card !
