The GSM dataroam mode is very similar with the GSM roaming mode. All the settings above apply to dataroam, but you still have to configure GPRS Roaming. After selecting the GSM dataroam mode go to BTS Configuration/Core/GPRS Roaming. In case you use your LabKit with Hosted Core, you should setup the following values:

  • NNSF Bits: 8
  • Explicitly map network nodes to IP addresses: 1=
