This iPhone is not currently setup to work with carrier you're attempting to use. Please insert another SIM card from a supported carrier or request that this iPhone be unlocked.
What should i do for the above proble, how should i know my phone is unlocked?
Your iPhone is locked to a wireless carrier. You will have
to contact that wireless carrier to see if they offer unlocking
and if you qualify.
What does it say when you look at Settings=>General=>About=>Carrier?

In your other post https://discussions.apple.com/thread/5001329?tstart=60
you say the iPhone originally was on contract with Orange UK. You will have
to work with Orange UK to get the iPhone unlocked.
