I have a report from a usually reliable source that he did not receive today's IPAWS/CMAS/WEA test message, and he surmises this might be because his phone handset is forced to VoWIFI. I have a number of other reports, mostly though not all, from the broadcast engineering community; nobody reported expecting a CMAS and not getting it, so that's not data here. Is anyone on the list involved with the FEMA/IPAWS/CMAS link, or knows someone who is, and has a channel to clear this query up through? I could be unsurprised to find that the carrier VoWIFI proxies missed out on proxying SMS Cell Broadcast, which I gather provides the underlying PHY for CMAS. Cheers, -- jra -- Jay R.

I now have a counter report that the Cellular Control Channel necessary to get these alerts to a cellphone *is not proxied by carrier WIFI-connect*, by design. I'm familiar with his credentials, and I'll assume he knows what he's talking about, cause *I* know what he's talking about, and he sounds like he's talking sense. :-) Thanks to everyone who responded. If you *did* get an alert, *and you know you were not in range of ANY cell network*, only WIFI proxy, that wasn't supposed to be possible and I would still like to hear about that.
