The O2 network establishes the Exabyte era in German mobile communications: In the past twelve months, customers sent almost 1 billion gigabytes of data volume through the O2 mobile network. This corresponds to about one Exabyte of mobile data. Never before has so much been consumed. With this data volume, you could stream music for more than 1.5 million years at a stretch. In a competitive comparison, the O2 network is therefore at the forefront when it comes to mobile data usage in Germany.
