I have an old Nokia 2280 on Telecom Pre-Pay, but perhaps this is relevant to more than just this particular phone...

When my phone has no space for new text messages, and I someone sends me a SMS, my phone displays "No space for new messages" on the screen. Obviously the network has somehow 'pinged' the phone to let it know there is a new SMS, and the phone then communicates to me that it is full, so it can't receive this message. Fair enough.

My question is - what happens after this? When I get this "No space..." message on screen, I usually free some space up straight away, but the past few times this happened I never receive the SMS. Actually, I can't remember if I ever have.

Does the Telecom network continue to 'ping' the phone every so often until the SMS is received, or does it think the message has been delivered, and never try again? I'm interested to know how this communication works for CDMA SMS delivery.

(Oh, and I don't need anyone to remind me to just "keep space free for new messages" to avoid the problem - my question is more about how the network works in this situation - I'm not annoyed with the behavior, more curious.)

Cheers,

Ash

EDIT: OK, so I should have searched the forum first, and I would have found this thread. I'm still curious though, this must mean my phone sends some kind of 'message received' confirmation back to the network, even though it can't display the message?
