It says the sim card that you currently have installed in this iphone is from a carrier
that is nit supported. What to do or how to restore it
did you purchase a new or used iphone?
Did you buy it unlocked? See here if your carrier is a supported iphone carrier http://support.apple.com/kb/ht1937
So you purchased this iPhone brand new from an authorized Apple reseller? Which one and where?
check sim valid in other phone or you call support center of company cellphone
