2 Problems..Sim Card Problems

If the Iphone works, all you have to do is reinstall Itunes.

Are you using a legitimate ATT sim card or are you jailbroken using Tmobile or some other GSM provider? you can try putting the phone into DFU mode. Have it plugged into the computer. and turn it off. Then hold both the upper sleep/wake button and the bottom Home button for 10 seconds. Then when you get to ten release the top sleep/wake button and continue holding the bottom home button until itunes gives you a message about it recognizing a phone in recovery mode. This should allow you to restore the phone.

do as it says you need a valid SIM to restore an iphone and it is possible to have a SIM go bad. There is nothing that can be done until your sim is infact working and valid and it MUST be an AT&T sim no other sim will work for restore.

Thank you for contacting Fixya Support I am glad to assist.

What you may need to do is eject the SIM card and then re-insert it and try to update your iPhone via iTunes again.

According to Apple, the iPhone has to contain compatible SIM cards from a supported Carrier and only those cards may be used to activate iPhone.

So make sure you have the right SIM card that is supported by the current carrier you have for your phone service.

I hope this information helps.

Hey I can solve this!!!!!!!!! ok step 1 : do you have friend that has a sim card? well if you do ask to barrow it then insert it step2: go to itunes and your iphone should come up step 3: ask him or her to insert there Billing Zip Code (i forgot to mention this, when itunes reconizes the iphone it will ask you to register it or whatever click continue) and ask your friend to put his or her personal **** such as email address an LAST 4 DIGITS OF SOCIAL SECURITY NUMBER!!! step 4: when thats done it have to install then it will let you into itunes then sync your music,videos yadda yadda yadda then pop out the sim card WARNING do not put your real sim card or it will do this **** all over again ALSO i do not know yet how to make calls or just look up fring its a app(FOR FREE on itunes) that allows you to make calls WITHOUT SIM CARD look it up
Overall (depending on the speed of your computer ) it should take 5-10 minutes and aslo you have your friends number programed onto your iphone but its better than trying to guess the PUK/SIM PIN

Calm down. Could be a number of things causing lost service. Restart the PC with iphone disconnected. Bring up itunes, plug in iphone and let the activation sit for a couple of minutes. If status does not change about sim card, eject the sim card using a paper clip, insert that paper clip into the tiny hole on the top of the phone. disconnect the phone, insert the card again, and reconnect. Let me know if this helps.
