I am guessing ur not on AT&T? Have u contacted ur carrier to see if they support the iPhone? And did u cut the sim sown urself? I have cut a sim down before with a sim cutter and the sim be to old and cut off parts u need for service. So I had to get a new one.

No way, I got my iPhone unlocked from AT&T too. Never got that congratulations message, but es soon as I connected it to iTunes, after deactivating it, I got service within 5 seconds.
So, either you have a problem with your SIM card, or if not, I would call AT&T again and wouldn't let go, until my problem is solved.

First thing I would suggest doing is calling AT&T again to re-confirm that your phone is unlocked
2nd thing is I would just request a brand new sim from your carrier provider and test it again
If they don't have a microsomes version, then I would be really careful on cutting it

Do you have a friend with a sim from another carrier that you can test?
My guess is you may have incorrectly cut the sim, even though its working in another phone, iphones require sim cards to be cut pretty precisely to read the data from

M having 4 microsims from 4 different carriers and all are workin in my other iPhones,but not in this one.
Whenever I inset sim, it's showing the proper carrier but in network, it show no network .
And when I turn off auto carrier, it shows every carrier,, and when select the carrier to which my sim belongs ,it gives error the carrier ur selected is no longer available . Today again I did the complete restore of my iPhone and again message displayed that my iPhone is unlocked and after that no service error continues.... Please somebody help me out... Could it be possible that my iPhone might be having antenna issue???

I has to be some hardware problem. Any service around were you could check it?

And you already attempted the turning on/off airplane mode?
It may look to be some specific issue with that phone then, and may be an antenna issue, cant say for sure
Has it ever received a carrier signal before it was factory unlocked?

Hello guys, I am too having the exact same problem as Santoshrok. I had the seller contacted ATT to unlock, then I restored it, it says "Congratulations, your iPhone has been unlocked".
Question from EVO "Has it ever received a carrier signal before it was factory unlocked? " No, it was "No Service" since the day I got the phone, and I thought the unlocking will solve the issue, but that's not it.

It just have to be a hardware problem. Hope that you have service near by.

The LAST OPTION I would suggest you do, even though you restored multiple times, did you restore to an earlier iOS version?
This is assuming your phone contains the necessary SHSH blobs for those versions.
That would be the last thing I would suggest doing to see if it "can" be an iOS version, but never hurts to try!

From EVO "..The LAST OPTION I would suggest you do, even though you restored multiple times, did you restore to an earlier iOS version?..
Not sure why we want to restore it to the earlier iOS version since the phone is at factory unlocked stage. One would think that they would let Itunes does its job as long as it's in working status.
