Q: My factory unlocked iPhone (AT&T) doesn't recognize my SIM card

Fellow Apple users,

 

I recently got my iPhone factory unlocked by filling the AT&T online iPhone unlock request form. I got a confirmation email from then & I waited 24 hours before doing a restore on my phone.

It tool me some time to upgrade to latest iTunes on my machine & latest iOS on my phone. All wen well until I reached the iPhone configuration wizard. After setting the language, region & Wi-Fi connection, attempts to activate the iPhone times out while contacting the Apple servers. I tried connecting through iTunes as well but it's been consitently throwing an error -

 

"There is no SIM installed in the iPhone you are attempting to activate. Please disconnect & insert a SIM card in your phone".

 

I tried disconnecting & reconnecting multiple times but with no luck.

 

Have any of you faced this issue & know how to get out of this? Any help would be appreciated.

 

Regards,

Shaz L.

iPhone 3GS

    Hi, I believe I have the same ihone and os as u. I also had the problem of it being recognized by the latest version of iTunes. The reason on my phone was that I hadn't used it or had it active for a few years and hadn't been updated along with iTunes thus iTunes newer version didn't recognize it. My solution was to take an old computer out of mothballs that I had and that had an older version of Itunes on it. It was instantly recognized and I was able to get to the Congratulations page, ( congratulations you have successfully unlocked your iPhone). One thing though, if you find an old version resist the prompt to update iTunes for if you update it you'll lose your only chance to have it recognized Good luck, I hope this helps. Robert

    You might want to look at the date stamps on the posts you're responding to.

    You're absolutely right, my bad. I don't usually get on forums but I just last evening had to deal with the problem and was surprised someone else was experiencing it also. Again my bad, Robert

    I am having a similar issue after I restored my iphone 3g. I am able to see the desktop but the phone will not recognize my carrier, it does not says invalid sim or no service, just when I check on settings, general, about, it says carrier not available. The phone was unlocked, jailbroken. I tried to restore it because it was acting weird (volume key not responding, etc).

     

    Version 4.1

    Modem firmware 5.15.04

     

    I appreciate any help and thanks in advance.

    And if you actually read the terms of service here, or spent a few minutes searching the forums, you would know that discussing jailbroken/hacked phones is forbidden by the terms of service.

     

    You can not get help here.

     

    Find an answer elsewhere or buy a new phone.

    I found this very useful. My dad somehow got my old phone stuck where I couldn't do anything and this allowed me to restore to factory settings.
