Invalid SIM Card on iPhone 4S (5.0.1)

Brand new iPhone 4S with ATT. Got invalid sim message less than 24 hours after activating. I tried rebooting and the airplane mode reboot - neither fixed the problem for long. Then I went to the local ATT store where they installed a new sim. Its been almost 24 hours so far and no invalid sim message. Phone seems to be operating normally.

Same f*cking problem! Vodafone, Czech Republic. After 5.0.1 update and few days of using I had "Invalid SIM card" once every day. Restart helped but I must do it every day! I ordered iPhone 4S in first Czech wave, no battery issues but only this. I don't know how to fix it, maybe 5.1 update? What do you think send it back or wait? I don't think it is a hw problem...

I have 5.0, never updated to 5.0.1. and have had this issue intermittently for 48 hours now. My husband on the other hand, also has a 4s updated to 5.0.1, does not have this issue. --yet!

we've tried: 1)resetting phone 2) remove sim card, cleaning and the replacing the card. this worked for 8hrs. 3) turn off cellular data 4) restoring... and yet, still "No SIM"

I'm going on 24 hours straight now. I'm beginning to have iPhone withdrawal.

I heard that it is a problem with antenas and switching betwen them. If phone has back conectivity to them it shows "invalid sim". There must be a good signal between both antenas, so if you have one bad you phone loses conectivity. I don't know if it is true.. I am going to try iOS 5.1.0 beta for developers tomorrow

I also have the same problem i was working on iphone 4 it was great and when apple release iphone 4s i bought it so i thought it will better than the old one and i update it to 5.0.1 firmware now i am using an old phone just waiting for the problem with sim card to be fixed . it's a great phone but i am not using it unfortunately cuz it keeps searching for signal and invalid sim and low signals can't do a call i wish i didn't change my iphone 4

So,

I installed iOS 5.1 beta for developers, restore from iCloud and everything is fine for a few hours now. I had only 2-3 signal marks with 5.0.1 and now I have stable 4 marks, looking good. I will reply tomorow if it is still all right.

F*ck! When I posted last reply SIM problem is back, so I don't really know, maybe new sim on monday 😟

The only thing that worked for me was a new sim.

5.1b didn't fix it, I can't see that 5.0.2 will.

Get a new sim ;)

I stopped in my Apple store and the guy I spoke to had no idea about this, never heard about it. Of course he didn't want to talk to me because I wasn't buying anything... his eyes were all over rather than looking at me while I was speaking.

Anyway, if it happens again I'm going to try the Genius bar first since they have some sim cards there.

🙂thanks for getting back sem7ex i am currently having the worst day yet for no sim messege i will get a new sim asap but i have no hope for it as others have tried and failed!

neott how long have you had your new sim for?

also does anyone know if apple is working on this problem? i can find much news about it all.

right now i have a 😠IPOD4s😠

neott,

and the sim card was same? same type and design?

I am goind to try my sim card from iPad now..

I contacted the customer Service in France about that invalid sim problem on a brand new Iphone 4 S.

I received the answer that their engineers are working on the issue and I should install the next update asap.

The customer service is calling me from time to time to see if there is somthing new and to give me some information to make me wait.

So it seems that it is a software issue ( that anyway most of us already suspected) and that next update hopefully ....

The sim looked pretty much the same contact wise.

I put in my new sim 3 days ago, no issues at all since then.... So far ;)

Guys please help. All you with SIM problems, are you able to make a call? When I try to call, it just holds calling screen (no metter if I press Cancel button). Then in 30sec period operator logo changes to "Searching". Sometimes in few minutes I am able to recieve calls again. When I just got iPhone out of box and updated it I was able to make few calls that day, but from then 3 days in row 0 successful calls from my side. But I am able to answer when phone sees my operator and somebody is calling. Also I can call on my 4s when microsim is removed (without sim tray).

Next week I will try to get big SIM, cut it and see what happens. As I saw on other forums, some operator SIM cards with specific design works. And from photos I see that SIM that I had on my 3G should work, but it was deactivated and changed to original microsim, that does not work on 4s.

Thank you Apple for all the time I already wasted for trying to solve problems, that you should be solved before releasing iPhone 4s and iOS 5.

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..
