Rather than edit the wiki, I figured I'd ask first.
Would anyone find it useful to list what works on which type of WiFi?
Example:
GoGo:
T-Mobile Wi-Fi calling and texting works (well I never tried the calling but, but it connects as T-Mobile WiFi)
iPhone imessage works
Panasonic:
T-Mobile Wi-Fi not available, so no texting.
iPhone iMessage works
