tonyhughes: Im quite happy. Looking at our corporate plan, the shared option is gonna work out way better for out voice and data bills. One of my users has 3 data devices!.
The data isn't shared though is it? Freitasm said earlier it is only voice minutes.
EDIT: Being able to share a data bundle across a handset SIM and a data only SIM in a USB modem etc would be great Telecom :-)
