When using your AirCard® 402 by Sierra Wireless, from the Sprint Mobile Broadband option in the Settings window, ensure Roam Mode is set to Automatic. If Roam Mode is set to Sprint, you will only be able to connect when you are in the Sprint network coverage area – that is, when you're not roaming.
When you are roaming (connected to a network other than Sprint), roaming fees may be incurred and certain features (such as Sprint Location Services) may not be available.
To enable roaming, from the Sprint SmartView software, click on the Settings window and set Roam Mode to Automatic. To disable roaming, set Roam Mode to Sprint (you will be able to connect only when you are in the Sprint network coverage area).
Note: Use the Roam Guard menu to specify whether you would like Sprint SmartView to display a warning message when you are about to connect to a roaming network for which there may be additional roaming charges.
