If you are unable to connect with your 598U by Sierra Wireless while roaming, try the following resolution:
From the Mobile tab in the Settings window of Sprint SmartView, ensure Roaming Selection is set to Auto or Roam Only. (If Sprint Only is selected, you will be able to connect only when you are in the network coverage area – that is, when you're not roaming).
If these steps do not resolve the issue, then please contact us for assistance.
