Some iPhone 4S owners reporting "No SIM card installed" error messages

Some iPhone 4S owners reporting
Back in mid-October an iPhone 4S owner posted a thread stating they were using their phone when it start producing SIM error messages, finally ending with a “No SIM card installed” message. Seventeen pages of responses later, this seems to be a reoccurring issue with no direct tie to any particular carrier or geographic location.

One site, Woo Servers, points out the iPhone 4 use micro-SIM rather than the mini-SIM form factor that was used in previous models. Woo Servers believes that the issue is directly related to a design flaw of the eject mechanism on the new SIM card tray. The blog post states that sometimes the eject mechanism touches the metal contacts on the SIM, creating a short circuit. It goes on to detailing ways to create a barrier with a non-conductive material, such as tape.

The Woo Servers blog post was originally posted back in July of 2010, obviously in reference to the previous model, the iPhone 4, and there has not been any word from Apple on this issue. Perhaps with the additional onslaught of iPhone 4S users experiencing the error as well, we will eventually hear from the creator itself.

Yeah, but if they didn't have the force close/battery life crap they would have no ammunition against Android. Let em think they know what they're talking about ;)

Its not just sim card reading errors,in shops we are noticing how iphone 4s are having major trouble keeping caller display on, the switch disappears due to problems with sim reading,multiple attempts at reloading the sims are needed to get the switch for turning on caller id to reapper. Some iphone 4s take at least 6 or 7 attempts to read contacts from sims to import into the phone. So now its apparent the iphone 4s,drops calls or greats silent out going calls,poor battery life,echo on speaker,tinted screens and has sim reader problems just to start with. The worst part is when this already faulty product goes past the one year warranty apple just tell people where to go..............straight in and spend all their money again on another faulty iphone

Don't you work for sprint? Sprint iPhones don't even use a sim card unless they use them outside the US.

Taco, you are correct. Sprint iPhones do not utilize the SIM card unless you are going overseas. But since its the same exact model device that is sold on all 3 major carriers it still does have the SIM card inside of it. So, regardless of whether you are CDMA, if the SIM card has an error the phone will still have an issue. Seems silly, but thats the reality of it.

LOL. Be prepared for every iTroll to thumbs down your post. The iPhone 4 had problems with periodically not recognizing its SIM card (a friend got a replacement phone 6 months into their ownership; the Apple store staff said they had replaced a few others for the same reason). Whether this is another antenna-gate, only time will tell.

It's cool. I'm used to it. In my opinion, the thumbs down button is basically the "I don't have a response to this comment that is worth posting BUT IT MAKES ME MAD" button. Which is why I never give thumbs down... I always have something to say :)

Weird...on my ANDROID phone I keep getting an error: "You do not have an iphone....your phone will work properly now...thank you"

"..after it finishes crashing, or after you recharge it for the 7th time of the day"

You do realize that the whole force close and battery life issues are sort of a thing of the past? While they are still present on some devices, the new phones releasing don't really have that problem. The iPhone4S on the other hand, well... you know.

the sheer number of iphone 4 we have gotten back instore which have 'frozen' or stalled during the upgrade to ios 5 process or a short period after is shocking. Fortunately for those us who work in retail most of those phones are over the measly apple one year warranty so we can't help them and let them complain to apple helplines elsewhere

Again if you work for sprint there wouldn't be any phones outside of warranty you're dealing with.

What? An issue with iPhones due to a problem with its hardware design? That could NEVER happen! In all seriousness, if people are having an issue then I hope that Apple fixes it. I also hope that the eject mechanism is redesigned for the next model, if it truly is the source of the issue. Of course, it could just be those evil Android fairies messing up those poor innocent iPhones in order to piss off their owners.

what i want to know is if this error is coming from the cdma iphone as well or is it just the ones that are using sim cards for service.

I know you seriously aren't trying to attack iPhone issues here. Oh heaven forbid one to mention all the issues a typical Android phone has, like the ones people complain about on your precious Motorola phones. Apple fixes everything with their phones.

Attack? So mentioning an iPhone issue is an attack on the iPhone? Yikes. WAAAAAAIT a second. Apple fixes everything with their phones? You mean like how pretty much EVERY AT&T customer needs to have a case for their iPhone4? Yeah. They sure fixed it.
