Sending and Receiving email with only Apple Watch Series 3
I have Apple Watch Series 3 (GPS and Cellular; AT&T; version 4.0.1). My iPhone is 6s (version 11.0.2).
How can I send and receive email using only my Apple Watch without my iPhone being nearby?
If my iPhone is completely turned OFF, I cannot do it.
If my iPhone is turned On, and next to me, of course, I can do this!
If my iPhone is On, locked, connected to my home WiFi (that has Internet Connection), and I am miles away wearing my Apple Watch, next to WiFi (that has Internet Connection and no Password requirement), can I Send and Recieve email?
If so, is this the only method?
Is this method unique to AT&T, as a Carrier, or all Carriers?
