The coverage map was updated again today. It looks like we've lost a huge amount of roaming on the west coast. WA-542, WA-547, WA-530, WA-20, US-2, WA-207, WA-410 and US-97 (between US-2 and I-90) all appear to have no service now.
Roaming on the east-west highways surrounding I-5 in Oregon is gone, and roaming in west Oregon and northern California have vanished too.
I'm hoping this is an error...if not I will likely be an AT&T customer very soon.
