Im looking for a messaging/ texting app that works on LTE when your iphone is turned off or dead? Any ?
SMS or iMessage? It sounds like SMS needs the phone to be on and on wifi/cellular for the watch to send SMS (depending on carrier.)
iMessage should work without the phone.
Yes imessage or email should work with the phone off. But im looking for any other apps that offer texting non iphone phones if and when your phone dies.
as I understand it that is not currently possible. SMS (short message service) is a voice service and needs the handset on and connected to a cellular tower to relay the message.
