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

thanks for the reply. I was hoping it wouldn't come down to it. bad show for apple, really not what you want when you cash out big bucks for a phone and it fails after 10 days.

Well yeah, not what you want to see but I also can pretty well guarantee that you'll be in and out of the apple store with a brand new phone in under 15 minutes, which is nice to see from such a large company as I guarantee it'd be a **** of a headache to address the same issue with a droid through verizon etc. (ask me how I know...had a 3G antenna break in a Verizon Droid3 after 5 days of use...took me two weeks to convince them it was an issue and even then they tried to give me a refurb)

one more thing, when I restored it it says it will install iOS 5.0.1 9A406 (originaly 405 was on it). don't know if that helps, but reading from this board I'd say no.

After flashing on beta3 iOS 5.1 my phone can't activate. After DFU restoring on previous original 5.0.1 all correct. SIM failure has again returned :-)

I been wait for official release.

Apple hurry up! )))

I've got the iPhone showing in iTunes now, but iTunes isn't offering any options except "Eject". now what? is there a way out? could it really be just the SIM card?

Selam Olgun,

Burda yazan tum problemler, benim Iphone 4s cihazimda da var, Avea kampanyasi ile aldim, micro sim kartim degismesine ragmen, 5.0.1 sebebiyle yazilimsal bir sorun oldugunu iddia ettiler. sen sanirim bir operator kampanyasi ile almadin dimi?

Beta versiyonunu da deneyecegim bi artik.

hi there,

it cant simply be a bad sim reader as the change in software has affected the issue. if it was just the reader or the sim this would have no effect.

You don't like to read do you?  By performing a hard factory restore it downgrades the software version to a prior one.  By doing so, with the sim issue still persisting, you have eliminated the fact that the software version running on the phone was the cause of the issue.

So 3 weeks into new iPhone I had this issue...tried several things - rebooting, airplane mode on/off, etc. etc.   Called AT&T...they sent me a new SIM card.  Fingers crossed but after one week...NO PROBLEMS!!

AT&T said I could have come into a store to get a free new SIM card but I don't live near one...so they sent it to me free of charge.

This might be the only real answer!!

joefrom RI, were you meaning me?

if so, i think you're back to front.

if the update to 5.0.1 means the sim card reader stops working

and

the update from 5.0.1 to 5.1 beta means it works again

then

it cannot be a faulty sim reader alone

if it was a faulty sim reader

then the software would make no difference to the outcome

so...

my iphone 4S (5.0.1 9A406) is behaving strange, when I restore it in itunes it works well and does not lose the signal. The problems start when I connect the WI FI, after a while he again begins to lose the network. I do not understand why it begins after connecting to the WI FI. hope it's firmware problem and not the phone.Sorry for my english.

tarasfrommiami: I have the same problem here! Even with iOS 5.1 beta 3. This is my second iPhone 4S with the same problem...

prrar - then it is a problem in firmware. So it is good, i hope the apple will solve this problem.

now I'm positive that it's a hardware problem: either the SIM card or the reader, as I have managed to instal the 5.1 beta 3 iOS. as the SIM that is refusing to work is a cut one, maybe it could be it that is causing the problem. but then again, why did it work in the first place? it does move about a little bit inside the tray. I'll try again once I get the new SIM.

Good news!!!! I've been experimenting with the issue for a while now. The best course of action is to go to an Apple store with a reserved spot at the Genius Bar. Make sure to reserve it beforehand and check in with a specialist when you arrive or they won't know you're there. The sim card itself is causing the issue in the phones; and they can replace and activate a new one in just a few minutes. I got a new 4s, researched all claims of newer software(jailbroken, developer, and official releases), went to the service carrier(they are happy to replace a sim, but Apple is more accustomed with their own equipment. Both are happy to take care of the issue and replacement over the phone, but it's much faster in person), tried multiple devices(iPads/ iPhones and sim cards, and also tested the issue under different conditions(hot, cold, damp, motion-stop tests(nice way to put it). Everyone was stumped with this one, but replacing the sim card is the only solution; and the only problem. It's cause is from continued use and heat from the device.

Are you desperate and want a guaranteed temporary fix? Freeze it! Just get the device cold(not too cold or you'll force a shut down, or worse, cause condensation to destroy the internals). This will work long enough to make a call.
