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

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.

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.

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!

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

First thing I'd try is a soft reset (hold down power button and home button til it turns off), then back on. Reset network settings, reset whole phone. Take SIM out, soft reset, put SIM in, turn on. If no luck then, get a new SIM card. If all of the above fails, its probably the reader within the phone. SIM cards can be so fun...

I have developer account, but it is not allowed to download beta 5.1. I know that I should be enrolled into program, standard or corporate to use beta sdk. But I do not want to pay just to try if beta 3 solve the problem.

I'm in the same situation. I bought my 4S in Belém, Pará, Brasil, and after 10 days, it started the SIM bug and the lost of signal. I tried 2 restores, one of the them with the SIM and a backup and the other without the SIM and with full restore. All the same! I also have a developer account but without paying the anual tax, you cannot download the beta. Well, let's wait the final release 5.1.

same thing happened to me this morning. After 2 apple techs they sent me to verizon. he did something on his end and told me to just take the sim card out.

works now. He said the next update shoudl fix it.

I had to restore the whole phone too.

Bought a 4s a few weeks, No Sim just appeared today for the first time. AT&T store guy removed and re-inserted SIM and it's working again. How long will it work? :dunno

Wow, what a mess, eh?

Hi Sethms,

I can confirm you that 5.1 beta 3 fix my sim problem, before that i had the problem every 15 mins. Remember, you don't need pay for the developer program, download it from another site which is sharing the update.

Greetings,

Francisco

Everyone who have sim failure problem just update to new beta3 iOS 5.1. And your problem will be solved.

In order to update you don't need developers account. Just download iOS 5.1 beta3 http://www.multiupload.com/UN5F70GHG0

Then you NEED TO UPDATE(shift+update) via iTunes. Pay attention UPDATE not RESTORE. If you restore you cant then activate your phone.

FINALLY I GOT WORKING IPHONE 4S

Thanks Francisco for help. But I did a mistake with restore and not update. I did not copy my UDID, and now my iPhone is unable to activate. I tried to downgrade to 5.0.1 and make update to 5.1 beta, but could not manage it. Will try something at evening.
