IPhone :: AT&T Unlock 4 Without A Sim Card Installed?
Apr 19, 2012
I just put in my request to unlock my iPhone 4 from AT&T.My contract has expired, and my old phone number is no longer active as of about 2 weeks ago, I also no longer live in the US (I've already travelled abroad), but they said that it would have no problem to unlock my iPhone as it's all done via iTunes. I still have my old AT&T Sim card, but the number is not activate and like I said I'm in another country.
I have heard for the unlock process to be completed you need an activate sim card installed in the phone. Does it matter what carrier's sim I use (can I use a local one?) or does it absolutely have to be an AT&T sim? I'm in Dubai now and have an active prepaid du sim card (they said it can easily be cut to micro-sim).
Contacting AT&T from here is a nightmare (the "international" number they gave me won't dial out and the website won't let me access my old account info since it's closed now and thus can't access their web chat either).

I got unlocked iphone 3GS through AT&T yesterday, and after email confirmation followed instruction, plugged in with itune, did factory restore succesfully. But after that itune didn't activate my phone, showed me message 'There is no SIM CARD installed in the iPhnoe I called AT&T again, they said initial unlock wasn't successful, so they reset unlock again and asked me to do again factory restore and then activate through itune.Unfotunately I can't do that now, because after previous restore I can't see any update, backup, restore button in itune, only showing me above message 'No Sim card~'. Now AT&T asked me to contact Apple, since they unlocked iphone. Apple is asking $29 , but they are not sure if they can resolve this. Also I am not in USA, so not carrying any AT&T or US number. Apple is suggesting buy new AT&T SIM and do this factory restore again, not sure if it will help.
Now I have 2 case open with AT&T and Apple, but both are passing envelope to each other. I'm feeling like a fool, since my iphone was working earlier with local unlock, but became greedy by hearing that AT&T is officially unlocking phone (which they did I guess So thought of upgrade to latest versions etc. I think I digged my grave.

It was working but signal from etisalat carrier was not so I turn it off until the apple logo appear but it cannot reboot it. Then I restore and updated the phone with itunes but know this message appear " There is no SIM card installed in the iPhone you are attempting to activate." The Man who sold me this iPhone told that this phone is from America and I thought it would work here like any other phone but in this case it doesn't work at all.

After upgrading the IOS version to 5.1.1 into my iPhone 4 I started receiving the message "No SIM Card Installed" constantly. I reset the phone and worked for a while, but then the message poped up again. Even the Airplane Mode "on/off" solved temporarily the problem but as the same as above, the message poped up again. I went to the local carrier store here (in Brazil) and the attendant told me this new version was not compatible with iPhone 4, only the 4S version. Anyway, I'm trying to restore the old version but when attempting to update, it goes straight to the 5.1.1 version. Is there any way to update until the 5.0.X instead?

I have an unlocked iPhone3GS that I used in Thailand for 2 years with a Thai SIM card. Now I am back in the USA and I got a AT&T SIM card without a contract. I wanted to update to the newer version of iOS so I contacted AT&T and had them do an authorized iPhone unlock. I backed up my iPhone and then restored it in iTunes. After restarting the phone iTunes told me there was no SIM card installed in the device. I've taken the AT&T SIM card out and put it back in but nothing changes.

Hey there, i've seen this question on here a few times, but no advice for my situation has been given.
Like many other's, my iPhone 3GS was working perfectly until i did the new software update. The sim card is installed, i have taken the sim card in and out, and done a phone re-set by holding power and home buttons until the apple symbol appeared. The problem persists. I am now travelling in Vietnam, so contacting my provider or an Apple store isn't an option. The phone is outside of its guarantee. I had the phone unlocked in China, if this makes a difference.
Any advice would be appreciated.

however, I want to replace it with the 16Gb card I have from my old phone. The problem is that I think that there might already be some applications on the existing SD card and don't want to lose them when I change over.I haven't been able to get it to work. My PC will only take normal sized SD cards, so that back-up option isn't one I can use. how I can take a back-up of the existing SD card, or even simply to transfer what's on it to the 16Gb card?
