I've been using iOS for 5 years and only recently I picked up a Galaxy s5 in a shop to try it out (haven't bought it, was just playing with it). There was no network in the shop, so I tried to send a text and noticed that the text didn't fail instantly like it happens on my iphone. The phone tried to send the text and to an extent put the text in the 'outbox' mail. Is there such a thing for an iphone? When I don't have any network coverage I don't seem to be able to send a text but as soon as the network is back the phone doesn't even try to send it. Thanks!
