Your phone could be carrier locked. Where did you get it from? How long has it been like that? Has it ever worked before with your SIM?

Assuming you just got it, and have never used it before with your own SIM, I believe your iPhone to be carrier locked.

You can use the IMEI number to try and find the carrier it is locked to, if it is possible to unlock, and the cost and time it takes.

For an iPhone 4, the IMEI can be found A/ on the tray of the SIM card, or B/ in Settings>General>About, or C/ by dialing *#06# or D/ by pressing on the "i" that appears before the activation screen when you first start an unactivated iPhone.

Services of this kind are available online on eBay and from independent websites. Just google something like "factory unlock service for my iPhone 4."
