I'm thinking of getting an Android phone (a Samsung Galaxy S2) but I need to know whether it queues SMS messages (when there's no carrier) and then sends them when it's in signal again, or whether you have to re-send as on the iPhone. As I don't get a very good mobile signal at home this feature is very important for me.
This is a general Android question that applies to all devices.
Messages (SMS) are queued if there's no signal. See screenshot (device is in airplane mode).
