Read messages on the arduino WITHOUT THE GSM shield

Hello,
I recently got chance to work with the arduino gsm shield. Unfortunately I failed to get my own. So I was wondering if anyone could give me any help in reading messages by the arduino without the gsm shield .I am using the arduino uno.

Thanks.

Reading messages from where? If you are referring to text messages, you MUST have a GSM chip with SIM card to receive them. Whether that GSM chip is on a shield, or not, doesn't really matter.
