I'm unable to send sms messages from the watch
I got an apple watch series 3 off of a friend they used the cellular feature on it and had a line. When i got the watch we reset it and i just connect to it through Bluetooth feature. Im unable to send sms messages from the watch it says "imessage failed to send" when i try? The people i message are android and cannot receive message. Im not sure what to do.
