Sim Card Failure No Sim with iPhone 4S Anyone Else?

When it comes to iPhone 4S issues I truly believe I had them all and after this new updated I gave it a shot and this is what I did.

First, I tried the regular restore as shown by Apple but for some reason my device wasn't eligible for it so I did the following;

1. backed up my iPhone

2. downloaded the so called tweaked update (9A406) from Apple site

3. connected iPhone to mac, started iTunes and pressed ALT key and clicked on restore and pointed to the downloaded (9A406) ipsw file and iTunes did the rest

after restore I did as a NEW, not from backup. plugged in my microSIM I was having issues with and for the last day or so NO, and yes that's right NO issues. I can finally use my phone... so I made a phone call after phone call, sms after sms. Changed the SIM pin, turned it off, removed SIM card I did all kinds of testing to see if the issues would come back and so far and keep in mind it's been some 24 hours or so everything's working as it should. Battery life is great. After some 24 hours of normal usage I still have 66% left and keep in mind I was doing all kinds of testing since my last full charge.

So for me so far so good, but like I said it's been only some 24 hours.

I try a lot of methods. I restore with DFU, like new phone, restore network settings, chage sim card to another and always problem comes back in few hours. And even new update to 5.0.1 (A406) didn't help. I wrote to Apple bug report, they asked me to send them logs from my iPhone. I'm like idiot sending this logs for a month and nothing, they even didn't answer to my bug reports on site. More then month I didn't have fullworking phone.

Apple, is it normal???

an update from my post 9 days ago... to reiterate, bought my new iphone 4s in Seattle 12/9 at ATT store... traveled to Oakland next day... sim card issues started some 30 hours after buying phone (after traveling)... got new sim at ATT in Oakland Saturday December 10... absolutely NO sim issues since (in LA since 12/12)... battery life still ***** IMO, but the MAIN issue of the phone not working due to Sim issues seems to have been resolved with new card ONLY, I did NOT upgrade to this new beta OS.

Not sure if we'll ever really know what the problem is, if a bad batch of sims, AREA of bad batch of sims, bad hardware in iPhone, a combination thereof, who knows... but, if it were me, for those of you still suffering the SIM issue, I would keep going back to get new ones, at different stores, and see if it doesn't cure itself. Since APPLE is not being of ANY HELP on the issue (it seems this OS update is useless for most), and lots of us have had luck with new sim cards, seems like the best solution at this time.

From Mexico: I have this problem about 24 hours after leave the store. I updated to 9A406, but the problem is still there!!! It´s incredible that this happen with and Apple device. An also, it´s incredible tha lack of "official" info from Apple. The silence is not going to resolve our (their) problems!

Not good, none of the ideas did not help .. The problem there is no Apple store in Israel which requires me to send the device abroad .. waiting to see if Apple finally fix the problem by updating the software. Just hope it's not a hardware problem

I tried all manipilations with sim card (changing, cleaning pins, scotch tape on pins) and upgarded to 9A406 according to official instruction. It worked for one day and now I still get "sim errors" 2-5 times a day! reboot iphone and sim is OK once again. Looks like it's a sw bug for me and I'm a IT guy with some expirience in such cases.

But what really frustrates me is that officially 5.1 is all about photostream feature with no reference that Apple acknoledges this issue and commits to fix it.

I sent a letter to Samsung PR department with a link to this forum, hope those guys will make buzz in press and Apple will work better.

btw I still love my iPad.

IT IS SO FRUSTRATING! I am getting so ****** off with it, it seems whenever I change mobile cell antenna that I'm connected to it happens! 😠

APPLE - SORT IT OUT!!! URGENTLY!!!

Going to try the latest 9A406 update but I can see on here that it has not worked for many so I'm not giving it much hope. Surely it can't be THAT hard to solve this problem?!

Has anyone been able to download and install iOS 5.0.1 (9A406) on an iPhone 4 NOT 4S?

I have an iPhone 4 NOT 4S and the issue is also on my phone, the problem does not appear every day but it is present from time to time.

Thanks

My iphone 4s works well with 5.0 but in 5.0.1 it cannot make call or send message. It shows no service in 3 hours and invalid sim in 5 hours. It is really annoyng . I checked 5.0.1 9a406 and 5.1 beta 1 and 2 but it cannot fix. Please help. Iam from Vietnam using Viettel network.

Problem Fixed! I have an iPhone 4s with AT&T and the phone unexpectedly displayed an error message that my SIM card was invalid. It then subsequently displayed "No SIM" in the upper left-hand corner. I tried all of the fixes listed on this post and nothing worked, so I gave up and drove to the AT&T store. I learned that it was a faulty SIM card that wasn't making proper contact with the phone. It is not an iPhone hardware issue. The rep at the store went to the back and re-issued me a brand new replacement SIM card on the spot for no charge. The process took about 5 minutes for the rep to activate my new SIM card and I was off. There was no charge to replace it and all of my data is intact. I would recommend anyone with this problem to not waste their time trying all of the fixes and just go to your local wireless carrier and let them fix it for you for free. Again, this is not a hardware issue - it's a SIM card defect.

I changed three times the SIM card.

The problem you had is a different problem described in this forum most of the problem began after the software upgrade to 5.0.1 to solve the battery problem was with version 5.
I just sent my iPhone to an Apple store so I could take a new one, hope the problem will not happen with the new device.

I had the 4S for a couple of weeks running iOS 5.0.0 and then updated to 5.0.1 - the trouble started.

Got SIM Error. Raised the issue with Apple and updated to a new 5.0.1 which didn't fix the issue.

Then got a new SIM Card from Vodafone. Problem got worse. Talked to Apple and got a new iPhone 4S within 24 hours.

The new phone was shipped with iOS 5.0.0 so I let it run for a while - no problem.

Updated OTA to 5.0.1 (the unpatched one) - no problem.

Updated via iTunes to 5.0.1 (the patchd one) - no problem.

Since several hours now I don't have any problems and battery life is very good.

Too early to dance on the table but I sense the new iPhone is not having any issues.

This problem is really weird I know that Apple is working hard on getting the problem resolved. If the new iPhone fix the issue than it's just adding another variable to the quotation.

Hope everyone is getting out of the troubles and have HAPPY HOLIDAYS!

So Mr. scowol tell me this... If it's the microSIM issue then why did my problems go away when I did the update and used the same microSIM?

Or why is the same microSIM in question working just fine on my wife's iPhone 4?

So next time before you start commenting please check your facts.

4S is the issue and as we can see in some cases it takes a new SIM and in others it works with the update.

In my opinion, the problem is also related to hardware.

Probably one sub model (P/n: MD234C/A Model A1387) in Apple's defective.
The fact that some iPhones have not encountered a problem and some did. And those that replaced the iPhone, did not have a problem anymore.

PROBLEM FIXED! (Iphone 4S, 16GB, last version of IOS 5.0.1, Vodafone IT, micro sim (not cutted))

The sim-error problem started wiht IOS 5.0.1. I've changed 4 SIMs and restored the iPhone more than 10 times, also with the last version of IOS 5.0.1 (9....6) Error appared 5-10 times a day.I was loosing hope when I read Stephan's post... I've followed his procedure :

<QUOTE>

1. Plug in to iTunes and back up.

2. Hold down the power (top) button and the home (bottom) button together for approx 8 seconds.

3. Release the TOP BUTTON ONLY after 8 seconds. As iTunes begins to restore the phone you can release the bottom button.

4. The phone will go back to the factory settings. You can then restore from your save back up.

Now everything works!!! 50hrs and no sim error!!!
