iPhone 4S unlock failed

[Alex Chen]

Hi, Guys

I bought a refurbished iPhone 4S about 1 month ago, and I've called AT&T to unlock my iPhone 4S, and finally they sent me an unlock successful notification email. However, when I tried to restore the iPhone 4S as per the instruction provided by Apple, it always said that the carrier of my SIM card is not supported.

"Only compatible SIM cards from a supported Carrier may be used to activate iPhone. Please insert the SIM card that came with your iphone or visit a supported Carrier's store to receive a replacement SIM card."

Since I'm not in US right now, and I don't have a AT&T Access ID, so I can't call AT&T directly nor launch a Wireless Chat with them.

Did anybody of you guys suffer such problem before? Do you have any suggestion? Thanks very much in advance.

Try this. It's worth a shot:

Take the sim card out. Wipe the phone and connect it to iTunes and when iTunes detects it, it should get
in contact with Apple servers to unlock it. Of course, all of this is under the assumption that you have
access to a computer with iTunes.

I would try removing sim and going into recovery mode
Phone off hold home button while connecting it to computer

Let if restore and activate before putting any sim cars in

Do you have access to an AT&T sim card you can pop in to activate the phone?

I've even had luck with a Nextel SIM on an iPhone 3G when I unlocked it. What carrier are you trying to activate with?

Thanks, but it doesn't work for me.

Yeah, I indeed have a AT&T sim card, I can activate my phone with that sim card, but I get the same error message after plugin in the sim card from another carrier.

The carrier I'm trying is ChinaMobile.

Yeah, I think so, but due to something, I can't call AT&T directly... not sure if there's any email address we can contact them directly, without the AT&T Access ID.
