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

Guys lets help Apple help us ... settings then about then model ... mine is MD269LL ... help please ... this invalid sim issue is really

the 5.0.1 was a disaster ... before it was just sim failure ... after update : no service every 3 minutes ... Support please explain what the **** is this

Update: got worse since iOS 5.0.1, happened about 5 times today, going to genius bar on Thursday, problem is how to get photos off the phone as I have a Windows 7 and they import upside down and cannot be edited!

I am very dissapointed with my new 4s, I got it 2 weeks ago from australia, it is factory unlocked, when it was ios 5.0 it went to searching for carrier every 20 min, and my battery last about 8-9 hours fully charged and no games 3g, wifi and 10 min of talking avarage, now after update (fully restored two times as new phone) it is even worse! Battery lasts 6 hours in iddle with all functions off (wifi, location services) and now I get sim failure and invalid sim every 20 min and when I try to make a call, also when it shows full gsm signal it is actually offline nobody can call me or sms, i can notice it only when trying to make a call as it goes to searching or to invalid state after this. I tried my wifes sim from iphone 4 same problem and she has no problems at all with my sim in her phone! I will never buy a new phone from apple so early better wait for halve a year or so.

ok, now a complete update with my issues:

- phone looses range regulary, after that the no sim issue comes, followed by no service. A hard reset or trying to call somebody multiple times helps for like a couple hours

- often when having carrier range and I try to call I get clicking sound and then after 30 seconds it says that call failed. After two-three attempts it starts connecting properly

- battery lasts short... no need to elaborate on that, you all know it

- yesterday I played around with the phone on wifi, later on I turned Bluetooth on and drove home having phone in my pocket. At home the phone was off and pretty hot. I couldn't turn it on for 15 minutes...

My first iPhone -> and I am negatively surprised with all those issues. Never had such a bad experience with apple before...

I am counting on a quick 5.0.2 release to address those basic issues, as not being able to make a call with a phone is to me an EXREMELY BASIC issue.

I just buy brand new iphone 4s 32 gb and same problem,Service is looks like working, but when i try to call someone its fail down and again tryin to search network its finding sometimes,sometimes not .So all people waiting information or update from APPLE ! Is there any one have good news ?

%101 same problem!

I`m having invalid sim error around 3 4 times in day. I need to reset phone from switch off button then it works fine till next invalid sim error.

is this software problem or ?

According to T-Mobile in Germany (and the Netherlands), the iPhone 4S "Invalid SIM" problem can be resolved by getting a new SIM-card. Apparently the latest SIMs have a different Infineon chip.

So, I tested my iPhone 4S with a brand new T-Mobile SIM card (which I had to BUY) and there are no more SIM problems and everything works GREAT now.

So yes, it is in my case a software problem because before iOS 5.0.1 I had no problems at all with my old T-Mobile SIM. It seems ridiculous that Apple has suddenly stopped supporting the older SIM cards, and now forces consumers and mobile providers to quickly buy new types of SIM.

This may cause grief and global SIM shortages if you ask me, and Apple still hasn't said or done ANYTHING to inform or help us.

Same problem here with Tele 2 Sweden as carreer. I have SIM card failure messages every so often (maybe once every other week so far, then it takes 2-5 reboots before I get the SIM card to work again). I also get the No Service message fairly often, and unlocking the SIM with the PIN does not always work.

This happened to me even on 5.0.0, just updated to 5.0.1 and I read online that other users report it might make things worthe but it is too early for me to tell.

I just tried taping over the part of the micro-SIM which is clearly in contact with the metallic ridge of the tray and will see if it helps. At least it worked after reboot.

Has anyone considered the case they have on their iphone 4s?  My wife just got a 4s brand new yesterday.  Within an hour of putting on a hard rubber case, we got "sim failure" and "Invalid SIM".

Taking the case off, then rebooting the phone (sometimes rebooting 2x) fixed the issue.  I'm not sure if rebooting more than once really was needed and it was more about a timing thing... .timing in how long the case was "off" giving the phone a chance to start working again?

The case we used was a very rigid rubber case.  I'm wondering if maybe odd pressure is being applied to the sim tray over time due to the case, causing it to either ground out the sim or make it lose contact.

Post #4 in this thread: http://forums.macrumors.com/showthread.php?t=403474  is what made me put 2 and 2 together.

As a test, we kept the potentially offending case on the phone overnight.  When we woke up, SIM FAILURE again.  She's taken the case off now and for the past 5 hours has been OK.

The issue has been reproduceable based purely on the case on the phone.

Does anyone else want to try this?  See if its their case?

Or has anyone gotten this error and not had ANY case on it?

I have a hard plastic case around mine. Had it from the very beginning. I will try without it for a while. It seems taping the part of the SIM card in contact with the metal part of the tray is not helping.

I had no case on my 4S on October 20 when I got the "sim failure". Re-booted and got it again in an hour.

Got new sim at AT&T and have not had the problem since. Have tight case on phone now with no problem.

For me it seems to have been the sim card causing the problem.

Just started having this issue today after having my 32gig 4s as of the first day they were released.  Only way I can fix it is to take the sim card out and put it back in and that works for about a few hours or so, then "SIM Card Failure".  Thanks Apple, I am becoming more and more dissappointed with every product I buy from you recently.  Called the store and they are out of stock for a replacement.  So I guess I have to make due with a useless phone for a while.  I assume Apple doesn't even pay attention to these forums anymore as nothing ever gets fixed.  Do I have sucker written on my face somewhere?

Got the same problem. I bought the factory unlock version in Hongkong. The first phone I tested, just showed invalid sim. So they gave me another one. After 24 hours, it started to show invalid SIM, and needed to be turned off and on again. It happened about 6 times in 48 hours.

Update:  case was off all day and it had "sim failure" at least 5 times.

Got a new SIM from a local AT&T store after talking to tech support.

So far so good. About 3 hours now
