entirely new market; mobile
delivery of information
•
Content owners are very
interested in the new medium
•
WAP is independent of GPRS and
other bearers; WAP services can
already be launched today

Charging for GPRS Services
•
Rule #1: KEEP IT SIMPLE
•
Monthly fee as primary charge
•
VERY low additional per-bit charge
•
•
•
Will go unnoticed by the average user
Will deter abuse by heavy users
Additional charges for accessing special
value-added services
