I think for many participants, using the GSM with old phones is the modus
operandi. Sure, many use dual-SIM smart phones, but from a point of view of
allowing the most devices to participate, I would prefer to have 2G instead of
only a 3G net. My plan is explicitly to again service voice to old phones that
don't speak AMR, and completely switching off 2G would be a step in the
opposite direction, probably a disappointment to many participants. It's sad to
do it, but if we have to, let's rather switch off 3G.

Much nicer would be to have spectrum for both. Can we try to ask around some
more? Did they say why they can't / will not allow it? Seems to me that limited
use inside Leipzig Messe for a few days hardly interferes with their network...

Would you like me to help with that, does it make sense if I also try to
contact operators somehow, or would it just interfere with your contacts? ... I
have no idea how I would reach the right people, but I could certainly try.
