Sorry, but I don't understand the specific technical thing. I live in Germany, so what does it mean for me? I need only a normal Sim-Card and must only pay for speaking time as for regular calls? My provider is Eplus. Can somebody explain me what I would need to handle encrypted calls? The only thing I understood was that I didn't need a data plan!!! That's make me happy. :)
Many thanks in advance.

So no, this has nothing to do with a common data plan. But well, HSCSD is not that much supported (and doesnt guarantee the high bitrate - only 1 timeslot is guaranteed I think, not the 8 you could get max.) , but I think CSD could be enough. _______________________________________________ devel mailing list [email protected] https://lists.openmoko.org/mailman/listinfo/devel
