I have the Pro1 working nicely on Canada's Freedom Mobile network. For those interested, I had to manually select the home network, "Freedom," whilst in a home network service area, then manually select the roaming network, "Nationwide," whilst outside the home network. After rebooting, the phone remembers the networks, switches automatically and properly identifies the roaming network as a roaming network so that Android's "Roaming Data" setting can be used to control data (Internet and MMS) when outside the home network.
I am having a problem getting VoWiFi working. According to the Freedom retail location staff member with whom I spoke, VoWiFi was already enabled for the number associated with the SIM card that I am using. After filling out the e-911 registration form for the number, on line, I received a text message saying that VoWiFi had successfully been provisioned. However, the VoWiFi options do not appear in the normal Settings menu, and, in the "*#*#4636#*#*" menu, the "provisioned" menu items for VoWiFi, VoLTE and Video Calling are disabled (and "off").
Any ideas? I have not called 611 yet, hoping that I might be missing something dead simple.
