Some iPhone 4S owners reporting SIM card problems

Some iPhone 4S users have already had to deal with batteries that drain far faster than normal. Now a new group of owners of Apple's smartphone have perhaps discovered yet another issue with the device. TUAW.com reports that some iPhone 4S owners have posted up messages on Apple's support forums claiming that the smartphone no longer recognizes the SIM card inside.

Apparently at some point the phone displays error messages stating that their SIM card is invalid or even that they have no SIM card inside the phone at all. Some of the reports have users rebooting their phones to solve this problem but it looks like for most of the people who have reported this issue, the iPhone 4S just doesn't seem to "feel" the SIM card inside it.

This newest issue doesn't appear to be related to the owner's wireless carrier as AT&T, Verizon and Sprint customers have all experienced it. It's not clear if this might be a hardware fault or a software bug, either. It's also possible that some people just got an iPhone 4S with a faulty SIM card. Regardless, the best advice for people experiencing this latest issue is simply going to your wireless provider and getting an all new SIM card.

SIM cards die. It's a simple fact of life. Unless the iPhone specifically fries them. Or unless it's about SIM cards users cut with scissors (courtesy of YouTube) in which case you have no one to blame but yourself about short-circuits. Anyway, don't see how this is really newsworthy. Maybe on MacRumors-r-us, not here. Cheers.

I just spend some time and read through the apple thread on this. It actually sounds like a sim card issue rather than a phone issue. If you read how people describe it they all say it happen within a few days of getting the brand new phone and then got either a replacement phone (i.e new sim) or a replacement sim from their carrier. This solved the issue. Sure sounds like a sim card issue.

Could this be a production of bad sim cards?

How can a phone they released last year still have so many problems?

Current Apple CEO: /waves hands magically, "What problem?" ROFL

Not having this issue. Phones been running flawless since day one.

@kiddingguy: it's probably just being magnified. I mean it is apple news good or bad.

Magnified?? It clearly says "some" not all.

Yes, but "some" on a tech news site usually requires at least a fairly large number.

This happened on iPhone 4, iPad 1, Sony Ericsson, Nokia and every other phone I had.

Not had this problem so far on 4S. Probably I need to change my phone's sim everyday to loosen the contacts a bit to replicate this problem.

Strrrange, for some reasons I donot have these issues (as also with battery).
Lucky me I guess.
Or is it just a tiny bit of all 4S users that are experiencing these issues. And are magnified??

Anyone here experienced that issue? Would be interesting to know how many of these are people who cut their own Micro SIM.

That's what I did. I preordered the 4S, was waiting for me when I got home from work, plugged it into iTunes restored it from the backup of my 3GS I had just made and was treated to a “No SIM” where it should say AT&T. Tried pulling the sim (which was difficult as mine didn't come with the SIM tray opening tool, so I had to find a paper clip to use) used an eraser on the contacts thinking it might have some residue and that did do something, instead of saying no SIM it said something else “No Signal” I think but can't remember exactly.

I figured the phone must be a factory reject but decided to try putting the unactivated microSIM from my iPad in just incase and whola “No SIM” changed to AT&T with full bars but I still couldn't use the phone to do anything with no account tied to that SIM.

I didn't have the patients to wait til morning when the AT&T store would be open to get a new microSIM so I pulled the SIM from my 3GS lined up the contacts with those on the DOA microSIM and trimmed using it as a guide, half expecting the end result being a useless 4S and now a useless 3GS.

It did actually work tho; the trimmed SIM fit more snug in the tray which is probably a good thing as the real deal floated around in the tray quite a bit. It works fine now, I had planned on going and getting a replacement but since its working I don't really see the need to.

My iPhone 3G used to do that... A good smack and a reboot solved it everytime, but you probably can't do that on the Glass On Glass new iPhones
