Was getting Sim Failure, no sim and no service, two maybe three times per day. Updated to 5.1 beta3 using links and instructions earlier in this thread. So far so good. Also, I can now stream to my B&W Zeppelin air from my 4S. Fantastic ! Thanks for the great support from fellow iPhone 4S owners ! - Mick
My 64gb iphone 4s has said no sim for a day now and it's only 1 week old. Is there a beta version that I can download on my mac? I tried the link mention 6 pages back and it downloaded a .exe file which I cannot use and after control+clicking check for updates I selected the file and received an error saying it was not compatible. Any ideas?
Had the same problem with iPhone 4s Verizon. Spoke with Verizon and found out sim card was never activated. Also the sim card that was installed was a global sim card, needing a global plan to be activated. The fix included 3 options; 1. Add global plan to account, found one with no cost, and the activate the sim card. 2. Reboot iPhone so you have service, then remove sim completely. 3. Go to Verizon store and get a new sim, one that is not global and have them activate it. Hope this helps :)
Hello guys.I had the same problem untill yesterday when,thanks to you guys,i found out about the update to 5.1 beta.i tried that and now i am experiencing no problem,from about 24 hours.No sim card failure,i can send messages at ease,the signal bars are not fluctuating anymore.Previously,i tried anything ,from changing my sim card to multiple restores.I even discussed the problem with both Apple and Orange here,in Romania,but,differently from your countries,here nobody seemed to know about this problem and that is so weird!Thanks to you guys,i never panicked,realised that is only a software problem and that is going to get fixed,somehow.Now i have a functionaly iphone 4s and i'm very happy.Thank you for sharing.
I did the Restore method to ensure that the firmware 9A406 running. Prior to that it was on 9A405. Its 18 hours and counting now that I haven't had to power-cycle my 4S every 30-60 mins just to get carrier network working again. No invalid sim or sim failure errors so far and surprisingly battery is at 50%. Prior to doing this, i have to re-charge the phone every 6 hours.
4S GSM/3G factory-unlocked from Korea being used in Indonesia currently.
on orange in uk
getting sim failure at least 15 times a day - have to turn off and on again just to get service
replaced the sim card - same fault
got a new 4s - same fault
restored to factory settings - same fault
put my card in someone elses iphone 4 - works fine
they put their sim in my 4s - sim failure
must be a fault with the phone? this is the 2nd phone and exactly the same problem with a new sim card too!
apple tried saying something about orange not activating my number to their network properly but why did it work in the iphone 4!
most amazing iphone ever?? ive had 2 and they dont even work!!!
any one who can shed any light id love to hear from
For the past week, every time I switch on my iPhone 4S, I get a SIM CARD FAILURE message and it never finds, but continues, to look for a service from ORANGE. Is this an issue for ORANGE or APPLE? I can't phone ORANGE to ask them because the phone doesn't work with the SIM FAILURE.
I notice other people here are suffering too. But there doesn't appear to be any word from APPLE about fixing it.
Do I deduct 7 days of payment from my service plan owing to the phone not working?
ssmakh and ESVV, Have you tried installing iOS 5.1 beta 3? I may be wrong, but I think EVERYONE (or almost everyone) in this forum who has had the SIM FAILURE problem and installed this "update" has found success. The installation instructions and links to the download site have been given in several earlier posts. Good luck. Mr. Luigi
It appears this is a known issue that Apple has not addressed.
I have the same problem with a new 64GB 4S that tech support tried to fix but now has asked I bring into a store for a swap out. But the time involved (including activation with my corporate server, download 35GB in iTunes, and the 4 calls today for support is going to take abotu 20 hours of my time.
It's been 4 days and I miss my Blackberry. Never had issues at this level. And the Blackberry was 20% the cost of the iPhone. It may do more, but my time is worth something as well.
Here are the links to a Nov 2011 article by Zdnet on this being an ongoing issue:
and to a temp fix with double-sided tape, no less!!!
Thanks Amazon! I hope posters who are still expressing frustration regarding their non-functioning iPhone 4S's are reading your updates. Whereas there may be some who will not find success by installing iOS 5.1 Beta 3, my somewhat quick scanning of this forum does not reveal a single person who has installed the update and not found relief from their SIM PROBLEMS.
Have a good day and, again, thanks for continuing your commitment to this discussion forum.
I've had this same issue with my 16gb 4s. Extremely disappointing when I was soo happy with my 4 and now I get his error 4, 5 times a day. Have to reboot the phone everytime I want to use it.
Will be going to my local CeX on Friday and purchasing a new Galaxy Nexus... Sorry Apple, gonna have to say goodbye
36 hours after updating to IOS 5.01 (9A406) still running properly and battery lasted whole day. Did a few tests by going to areas where 3G signal is weak and walking back to area where signal is good. Phone switched from 3G-EDGE-3G properly under 20 secs.
Looks like phone is finally normal.
Just additional information:
Phone came with IOS 5.01 (9A405) factory unlocked, Korea version. I got both a 32g White and 64g Black. Black is still unopened as it is a gift for someone, will be doing the battery charging on the Black in a few days and will use the same sim card in the Whitey.
Will report back if Black encounters the same issue and if the 5.01 (9A406) fixes it if it encounters the same problem. I'm hoping it does because that narrows it down to software errors instead of hardware error within a reasonable doubt.
