    I think that SIM issue is much worse than Battery issue, it looks like SIM issue has every third iPhone, thousands posts in the forums.. really bad and no news from Apple..

    *Update* I realize this doesn't help most of you because you're running 5.0.1 already, but I had 5.0 and was also having this issue. I restored and updated my phone yesterday. I haven't had a problem since. Going on 24hrs now. fingers crossed!

  • ptnik Level 1 Level 1 (0 points)

    That's exactly the symptoms I also have. Call failed, network lost, searching... back on again (but no mobile data even though it shows 3G).

     

    Making calls without the sim tray, that I had not tested... and it probably shows that there's something really weird in the software apple is using. (As well as having Invalid SIM errors in CDMA customers!)

    hello again just some info i have noticed when my signal goes down to 1 bar (orange uk) it hangs there for a while then the no sim sim failure invalid sim happens so i turn off my phone and back on and then i have searhing for a while then no service then full signal and 3g this makes me think its something to do with the dual antennas dropping signal and sending the wrong message to the phone i hope this can be a fix as my new sim has done nothing an orange uk havent even heard about the issue so i would to know if apple has recognised the problem yet???

    also this tends to happen between 6am - 6pm ???

    ABSOLUTELY Ridiculous. Apple need to fix as soon as possible, keeps dropping signal- how can i possibly use a mobile that wont recieve or make calls or texts and shows 'invalid sim' !!!!

  • momneedscoffee Level 1 Level 1 (0 points)

    Well, I was in the middle of a phone call and it went all "invalid sim" on me. So between that and the keyboard keys/lock sounds not working when set to work (they go in and out - crap shoot if it works or not) I set up an appointment tomorrow. This is ridiculous. I had less problems on my outdated 3GS.

    Ok, went to Apple, they did a full on reset. We'll see what happens next.

    I have invalid SIM @ Singapore too. Had change a new SIM card and new iPhone 4S still can't resolved. From my discovery, this is due to we are using Multi-SIM for our iPhone and iPad. I even switch my iPad to airplane mode and to Wifi , it still gave me the problem. Now, I change my iPad to another SIM card and I doesn't have this problem for 24hrs. Proven that Apple need to come up a new OS to resolve this quick else all user will be unhappy with it and switch to another phone model soon.

  • ptnik Level 1 Level 1 (0 points)

    Finally a glimpse of hope...

     

    I had a contact from Vodafone telling me that this was indeed caused by some SIM cards - and they'll now be sending a couple different ones to see if this gets proven once and for all.

     

    For the worst part, it seems that this issue will potentially plague most of their SIM cards - and they're trying to find cards from another supplier/manufacturer that have no issues with the 4S.

     

    In any case, I still find it very weird that Apple could do such a mistake - SIM cards have been a "standard" for years, and never had any issue before... and now, on a brand new equipment they would have such "basic" incompatibilty problems? In any case, I just hope this finally fixes it... as these weeks with the iPhone 4S have completely shattered my trust in the iPhone and iOS experience (I have to manually call a "dummy" number just to make sure I'm reachable and have a signal, every 10 or 15 minutes... and every delay I get in receiving 3G data prompts me to instinctively do yet another reboot.)

     

     

    Just for reference, symptoms have changed slightly as well. Now, besides multiple Invalid SIM errors every day, instead of showing a 3G status and having no data connection; now it simply shows no data indicator at all. Just the operator "full strength" indicator. I still can't make any call: shows call failed, and goes through the usual process: no bars, searching, back again. But now, it seems to be able to recover the mobile data connection back to 3G without rebooting - until I get a "proper" Invalid Sim, that is.

     

    ... Just hope it really is the SIM card... and if, as they say, this happens with their most popular SIM manufacturer, I expect a few thousand more complaints starting to pop up in the coming weeks/months.

    Am from Singapore as well - hv the same error as well.  I hv been having numerous phone calls with the Singtel call centre and all asked if I was using the multi sim card - but not one told me me that multi sim was incompatible with IPhone 4s.  Furthermore I only bought the ph a week ago. They made me do all sort of stupid tests and then said I wld hv to go down to comcentre to technical dept.  It was when I was there I was told it was an incompatibility issue - then why the **** did they not inform me of this when I bought the phone and specifically told them I was gonna use a multi sim. It is gruel irresponsible of Singtel to mislead us like this.  If the cow ter guy at comcentre cld tell me this and then proceed to tell me it was pointless to change the phone - tat means they are already aware of the problem right????

     

    I am so furious with them - I waited for the 4s and now I can't use it effectively- what the **** do I do? They shd give us the option to swop to the 4 cos I was told it doesn't hv the same problem

    Hello again just a quick update I have spoke to my carrier orange uk and he said he has had a lot of complaints with the issue and that it's more likely down to the sim card (I don't think it is!!) any way ordered anothe micro sim and thought I would do a full restore and set up as a new phone after it was done I had no invalid sim messages for the rest of the day I used to get one guaranteed when I woke up but nope all was good so far tho today in uk it is 2:20 and I've had 2 invalid sim messages usually I would hav had 9ish and also my signall has been awesome and 3G all day so the restore did help but didn't fix which makes me think it's gotta be the IOS only thing is are APPLE bothered now they have our money so far I think not.

    I'll update when I get my sim

  • raul oscar Level 1 Level 1 (0 points)

    Hello, I'm from Argentina, purchase an unlocked iphone 4s, and I put a line of the company Movistar. At first it appeared at all times the message invalid sim. Upgrade to 5.0.1 and now I get that message not only gets the company logo and full antenna signal, but I can not use the phone to receive / make calls. Something strange, if it works over 3G navigation.
    If not go to the phone company here in Argentina or Apple, I do not think either can give me a solution
    Greetings from Argentina

    Right here we go again I finally rang apple technical support and they made me an appointment at my closest apple store for tomorrow when I rang and explained the invalid sim I keep constantly getting and told him about my full restore which didn't fix it he said what I expected that it sounds like a HARDWARE problem not software as I thought because this has happened from ios 5 to 5.0.1 and 5.1 beta so a developer has posted aswell so I'm getting my new replacement iphone4s tomorrow I will give it a week and let you all know if I get the error again?

    I'm still hoping I'm wrong and that it is software problem but if an apple technical support guy says hardware well I think we're doomed till we replace I reccemend you ring up ASAP!!!
