You need to restroe your phone with iTunes. When the unlock is successfull, you will receive a congratulations message.
Sounds like you haven't completed the unlock process.

Thanks for your response. I did restore my phone with iTunes. I won't mind doing it again (to ensure if I did it the worng way before) but the problem is that when I connect to iTunes now, it doesn't give me any option other than to Eject the phone after giving the above mentioned "No Sim' error.
Also on the phone, it keeps on searching for the carrier & then finally displays "No Service" at the left top. Also, it allows me to configure the phone till the point it tries to activate my iPhone where it times out & there is nothing I can do further.
Some extra information if it may help - i bought my 3gs in USA from AT&T & now trying to use it in India with an Indian carrier.

Does anyone have a resolution for my SIM problem?

I have the same problem. iphone 3gs, unlocked by At&t, restored ios several times but still stuck in "There is no SIM card installed in the iPhone you are attempting to activate."

I wish I could see my Home Screen. I followed the steps as mentioned in your second link about unlocking (mentioned below) -
- Ensure that you've waited the recommended wait period provided by your carrier.
- Back up your iPhone.
- Erase the contents of your iPhone.
- Swap the old SIM card with the one for the new carrier.
- Complete the setup assistant and restore your backup.
Only thing that I have not done (not sure if that matters) is the part where it says swap the old sim card with new one. I did not have my old sim card so I had my new sim in the phone all the time during the restore. When it didn't work I tried to do a restore once again in recovery mode without the sim & then inserted when asked.
None of the above stesp worked for me. Is it mandatory to have the old sim (AT&T in my case) to complete the unlock?
Let me know.

So it would seem... Hence the reason it is not working for you.

As it's a matter of my iPhone, I just want to make sure if your last response is just a guess or it's really the only way it can be done. I somehow find this point not so relevant.
If the above is anyway true then do you know of an alternate option because there is no way I can get my AT&T sim now.
Let me know.

Was your phone jailbroken, hacked, or unlocked by someone other than AT&T before you processed an official unlock request with AT&T?

Then you now own a brick. It is permanently damaged. Buy a new phone. That one will never function as a phone again.

make sure you are not in "airplane mode" when you are "activating"... same thing happened to me until I switched off airplane mode. once I did that, it recognized the sim just fine and activated. once unlocked... I believe it should activate with any sim, including one that has no service (like mine)

where do you go to fill the AT&T online iPhone unlock request form.
