Minute units will be eliminated and the best thing is: The new travel option is free for customers using the tariffs O2 Blue All-In Professional L and XL as well as O2 on Business L, so there won't be additional costs for business tariffs.
With the new EU+ Travel option business travelers always have full cost control, as the international flat-rates apply in the 27 EU countries as well as in Switzerland, Norway and North America. EU+ Travel will first be available for customers who book either O2 Blue All-in Professional L and XL, or O2 on Business L.
