Google Translate: Where a mobile phone company provides an internet tariff with "unlimited" data volume in general terms and conditions,, it may not drastically limit the speed of data transfer after exceeding a limit . This was decided after a complaint by the Verbraucherzentrale Bunde Association (vzbv) against E-Plus, the district court Potsdam.
E-Plus had promised an internet access with unlimited data for its mobile tariff "Allnet Flat Base all-in". The power restricted the company in the same clause but crucial one: customers could only transmit data to a volume of 500 MB per month in fast speed. Then they were allowed to continue while using the Internet at no extra charge - but 500 times slower than before, because E-Plus slowed the transmission speed of 21.6 megabits to 56 kilobits per second.
