The "home network charges" roaming model has unnecessarily
over-complicated this issue. The problems they face to get GPRS roaming
working wouldn't have to be there. Those problems are home grown. Change
the roaming model and those problems will disappear.
The "visited network charges" roaming model (i.e.ZEBRA) doesn't have any
issues with GPRS roaming at all, neither technically nor logistically.
In fact GPRS service comes as a side effect. This is because a roamer
becomes a local user of the visited network (temporarily) and therefore
gets local GPRS service there just like anybody else (provided that the
visited network has GPRS of course). The home network has nothing to do
with it. No issues with roaming whatsoever. No extra equipment required.
No adjustment to any roaming agreements necessary.
One more reason why the alternative model is a serious contender.
