I got my phone last week. I was unable to activate my phone from home (no network found), so traveled to a Sprint home area where it activated quickly. While there I made one Republic WiFi call. Since that time I have been unable to roam, I only connect in Sprint areas, never roam. I can connect to any open WiFi network and get email, etc, but my Republic Wireless app status always shows "WiFi calling disabled, click to configure". I routinely disconnect/forget the wireless network and reconnect, but this seems to make no difference. I have taken out the battery for over a minute, but still no joy.
