Apple Watch not sending messages
I received my Apple Watch Sports today and found that I was able to send messages to people close by (as in, same building) but not to people further away.
Specifically:
Watch > iPhone (on same wifi as Watch/my iPhone) sent and received okay
Watch > iPhone (not sure if on wifi at all) not sent
Watch > Samsung S5 (not sure if on wifi at all) not sent
Has anyone else had this problem? Is there a setting I have missed?
Apple Watch, iOS 8.3
