Limits
No 911.
A Wāteo device cannot call emergency services. If you need 911, carry a phone that can, or run a VoIP app with a registered address.
No voice, no SMS, no phone numbers
Wave and Beam work between handles. Calling a phone number is up to whatever app you install, and that app's provider.
Coverage is the sponsors'
You get the coverage of the carrier you pick. Current sponsors: none signed yet.
It's a pilot
Things will break. When they do, it goes here.
