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

It appears that exchanging phones sometimes works and sometimes doesn't.  An exchange of phones can be difficult for some of us because of where we live.  Also, there are probably enough exchanged phones in the pipeline now that when you get a "new" exchange phone it could very well be a refurbished phone (something about that bothers me).  So that all of us could get a sense of how effective an exchange of phones is in solving this problem, could those of you who have exchanged for another phone kindly post one of the following:

Option 1:  Exchanged phones...Everything works fine now.

Option 2:  Exchanged phones...Still have the SIM problem.

Sorry to impose, but this may help some of us to decide whether it is worth the effort to go through the process of getting a replacement phone.

Thanks very much, Mr. Luigi

Hi All,

After many weeks of terror my iPhone was exchanged. The new one is Model MD261B and came with iOS 5.0.

Since it has been working for some days (and nights) without a failure I have no intention to upgrade it to 5.0.1.

BTW it's amazing how it works fine, I was getting used to the trouble.

Best Regrds,

Jose Geraldo

i did same i got new iphone 4s Model MC921LL and it work fine with IOS 5.0.1 .

and i hope all did same give your iphone for exange at the moment there is no other solution

Wow,

It seems I'm not alone.

I have a uk ips4 which, for nearly a week, has been telling me I have an invalid sim.

I have ordered a new sim but am now concerned about its success.

It is running 5.0.1 at the moment and although I can understand the prospect of it being an update issue can anyone explain why the same problem doesn't exist on my ipad2 with the same oft ware and sim?

I have now had my 3rd iPhone 4s fail moved to another country had the last phone for 5 days working then it crashed lost phoning ability, updated to 5.01 rest restored 5 times,

But this one has a better battery life, than the last two,

And nothing no sim,sim failure,  can't make any calls in or out.

And they won't replace it in another country, so I have to go back to the country where I bought it from,

So apple is not exactly good at making phones any more, I want my money back, and will I get it I doubt it very much.

Ironically, ios 5.1 beta 3 fixed my 4 month sim card problem 1 day ago. It seems like apple wont do anything until someone push them. Before it's Steve and now it's all the users.

I think that the final version 5.1 will solve the problem with the loss of the network. Let's wait and hope that apple will do everything possible to solve the GLOBAL PROBLEM.

And one more thing.If the apple does not solve that problem then lose a lot of fans around the world, and then begin a gradual decline.

Hi Andy

I joined your club on Christmas Eve!

Hello S2

4S was a head ache.  As everthing @ home is Apple based!

I hope Apple reads this and in Steve's word it is s***.

So I tell everone on this board to do the same as I checked this board 3 weeks ago at 46 pages and today 56.

No news from Apple.

Sam

I've installed new release of 5.1 beta firmware today (5.1 beta 3) and my 4S works normally now. I've installed new 5.0.1 as well as both releases of 5.1 betas (beta 1 and beta 2) and it had not fixed the problem for me. But now everything works smooth and my iPhone dosn'l lose a network every 20 minutes like it was before.

Hi Alsammak

Welcome )) , i just keep getting updates of couple of apple disscussion threads on email including this and it is very interesting when apple fix this. I read and reply from my S2 and now just smiling reading all this, btw another two people got s2, so total 6 including me, 6 people LEAVE!!! apple, before they ALL wanted iphone some of them had 3GS and it is all after my free "AD" for apple phone. What i did, i just gave them link to this customer "support" page and gave them my dusty "iPOD4S" 64GB from my drawer. Another notice, I have friend who bought iphone 4S 64 white for his wife on new year.... It is on the way back to store! And this is not SIM FAILURE as mine, when she makes a call people does not here what she says just silence, why I telling this here.. becouse apple is not what it was when Steve was there!!! And it is a SHAME! to sell such "phones" keeping in mind that it is the most expencive smartphone! And now it is the most buggy! And this is all ok if they fix it! But now apple is the most ignoring company! Mark my words, after 3 or more moths something will change on phone market and it will be not good for apple and probaply this forum will play not last role in apple's phones sad future (not talking about iPad or mac pros.. keep waiting for iPad3).

Have a nice day!

Andy

Hey guys!!

I also had this problem. Changing SIM Card solved it...this has to do with compability issues. The first SIM card i had was recent. Didn't work, was getting the "invalid sim" message all the time. Bought a new one and the chip looked different. Worked like a charm, never got the message again...

Best of luck!

Cheers

I got the same issue with my iPhone 4S, bought in Canada (model MD244C, iOS 5.0.1 (9A406) ).
