I'm on ATT now but switching to Sprint soon. How does Sprint handle calls forwarded from landlines that are provided by cable service? My initial thought was that they're probably treated like landlines and count against minutes, but then I thought maybe not since they're not traditional landlines. What about calls that come from VOIP callers - they're not landlines in the traditional sense either? I know neither cable provided or VOIP calls are considered mobile, but they're not traditional landlines either. I'm considering switching to one of the EverythingData Family plans so that's why I'm focused on the minutes calculation. Thanks in advance for any replies.
