Please see my iPhone 4S details;
- Version: 5.1 (9B179)
- Carrier: STC 12.0
- Model: MD239AE
- Serial Number: DNQH15VGDTD2
- IMEI: 01 304200 700144 6
- ICCID: 8996 6012 1003 3157 867
- Modem Firmware: 2.0.10
Purchased Date: Feb 5, 2012
From: STC (SAUDI TELECOM CO.) "UNLOCKED".
Worked fine using sim card from STC 3G (IN SAUDI ARABIA)
Worked fine using sim card from China Unicom 2G (ROAMING IN SAUDI ARABIA)
Worked fine using sim card from STC 3G (ROAMING IN UAE, DUBAI INTERNATIONAL AIRPORT)
Worked fine using sim card from STC 3G (ROAMING IN BEIJING, CHINA) on February 10, 2012
Worked fine using sim card from China Unicom (2G) from February 10, 2012 to March 6 or 7, 2012
Used iTunes to updates on 6 or 7th of March
Seems working fine
I received a phone call from a friend, while calling I noticed network signal dropping and the NO SERVICE appeared.
Visited Apple Store in Beijing and had a appointment with Genius Bar on March 10, 2012 at 11:10 AM and this is the outcome;
- Reset all
- Restore to factory setting
- Used their own sim card
- Turn on/off flight mode
- attempt to restore older ios, but won't accept
They suspect a hardware problem, but without any specifics.
I updated the device with the last ios released on 11 or 12 of March.
I replaced sim card from China Unicom with a newer sim card 2G and got a newer micro sim card (3G)
Both cards are not working and (NO SERVICE) still there after restore and reset all been done.
** All sim cards from STC, China Unicom were tested on other brands and worked.
** All sim cards also were tested on iPhone 4 (my wife's phone) and working fine.
Finally, I am about to run over this device or use a hammer and send the junk to Apple. I am an old man & can't afford to be stressed.
Before I do that, can anyone HELP or can APPLE find a solution!!!!!!

Ok I am not an expert but I myself am waiting for a new sim card from STC for someone to send me by mail here in Canada. But here are my suggesions (any high level users , please share your suggestions for the No service issue):
- Make sure your Iphone 4s is Factory unlocked when you purchased from STC (maybe it was locked to STC carrier and that is why you are having problems when using Chinese Carrier.
- Try to get someone back home to send you a fresh New 3g STC Sim card. Note they will disable your current one when issued.
- Maybe you can attempt to set up the phone as a New phone (instead of restore from backup) with the Saudi Chip inside and activate this way.
- Finally call 902 from your STC sim card (they do not charge roaming) and explain your problem to them.
The good news is NO service is better than invalid sim. Since you bought your phone from the carrier (STC) they should be able to solve / replace your problem.
Finally if you want peace of mind and you have extra money, just buy a factory unlocked phone from the Apple Store in China but make sure they activate it with the SAUDI chip in it before you leave the store.
Though i am Tamayouz (VIP) user with STC i never bought any device from the carrier. I always bought from England Apple Store or Canada Apple store because of the Genius Bar support and so it is factory unlocked.
I wish you all the best of luck. I hope STC solve your problem , or you will have to wait to go back to KSA and visit them to solve it.

I has been close to 4 months that I have had to turn my phone off and on about 50 times a day to get my signal back. Since I installed 5.1 the device is stable and working just fine. I know it is early days yet to get to excited, but one can only hope that the new iOS ver 5.1 has solved the problem.

Thank you for the suggestion mobi007.
I had my phone working fine for almost one month using STC and China Unicom. Both worked local & roaming. My iPhone 4S is a factory unlocked.
I had a chat with Apple support (USA) and they suggested that I check with STC.
My phone is still in "NO SERVICE" mode.
***I am about to make up my mind and cut ties with Apple & its products forever***

hello Mr Garnik
Are calls getting dropped on your iphone 4S when you keep your "Cellular Data ON" ?
My 4S keeps on dropping calls at fixed intervals whenever I keep "cellular data ON" ( 3G or EDGE).
If i turn it off then calls are not dropped.
I'm Using Orange-Armenia.

found this on another thread not on an apple dicussion forum hope it helps
We had the same issue , invalid sim card after updating to ios 5.1 , after many frustrating hours of trying everything from trying new sim cards from our provider....3 in total...to standing around the Apple Store for hours only to be told there was nothing they could do as the phone was out warranty...nice huh? Apple product screwed up by Apple software update....nothing they can do? My son took the phone to a little kiosk in the mall that does unlocking...and he figured it out! The phone was originally locked to another provider other than the one we are on so when the software updated it locked it back to the original provider...invald sim.....but get this , the original phone bricked with a fatal hardware issue so we were instructed to take it into the Apple store for a replacement.....turns out that all the replacement phones are locked to AT&T and then unlocked to be used with your provider , after we updated the software it locked it back to AT&T ....we are on Rogers. My son took the phone back into the Apple store armed with this information , they checked their records and low and behold were able to unlock it again....problem solved.
THE APPLE STORE CAN FIX YOUR PHONE!!!! Don't take no for an answer
