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

Yes, solved by getting a new SIM card from my provider.

Had Apple (France) on the phone yesterday.

They told me they are aware of the problem and are working on it in conjunction with the operator to find a solution.

They also told me the solution would be to have a SIM replacement, but only after they have solved this problem.

This solution is due to some time next week.

Meanwhile, they offered me a phone replacement beacause I proved that inserting my SIM into another iPhone 4S (with 5.0.1) would not cause any problem.

I am waiting to receive the phone today or tomorrow. Will write here if it solved my case.

Else, we need to wait for Apple to work out a solution with the operators involved.

Interesting. Neither Apple Poland nor T-Mobile PL seem to have any clue about this issue. They're shooting in the dark with random advice like hard reset, clean restore etc.

This is all very weird because this phone (4S 64GB black) worked fine for like a month until I started to get "Invalid SIM" a few days ago. It seems that the intro of this problem was somewhere around the intro of 5.0.1.

Yes, this problem is relagted to:

iPhones 4S

iOS 5.0.1

Some SIM card series

So if you get lucky and get a good serie for the SIM replacement, problem is solved. (apparently)

Exatcly same here. Just called T-Mobile PL and they said that they don't offer 128kb cards, just 64kb and that I am the ONLY person who has this problem. They suggested to go to one of their stores and have the sim card checked... hmmm

Have received my iPhone 4S replacement after not even 24h.

It solves the problem for me as I will keep the phone on 5.0 and not update it!

I'll write something here if I get any news from the provider concerning the SIM problem.

Suppose, if they solve it, other provider around the world will have a solution too.

I`ve got the same problem on Iphone 4 after upgrade to iOS version 5.0.1 - no inbound calls or sms while iPhone is switched on with locked screen. And Its not a sim card problem, because its working fine in old iPhone3G.

Apple guys, please solve this issue as soon as possible - I cannot use my Iphone4 anymore!!!

P.S. I did upgrade via WiFi. I`ll try to restore iPhone via iTunes, but not sure it will helpfull.

Went to the Apple Store yesterday. They told me to get my provider to give me a new SIM card. I told this to my provider Vodafone, but they asked me to call their tech support first. So i guess i'll do that, they won't solve the problem, but in that way i can get a new SIM card for free, if not they wanted me to pay for it lol.

I haven't had problems since Saturday though, and it is only every now and then I experience this problem. It's very annoying when it happens though.

Just talked to customer support at Tele 2 Sweden.

They are aware of the issue and working with Apple on fixing it. They claim they have no other type of SIM card (according to other posts in this thread, changing SIM card helps, so I guess they mean they don't have any other SIM card type in stock).

The fix will be in form of a software update, so it seems that replacing SIM card will not be necessary once the update is out. They say the update might come this week but it's not sure.

Unsurprisingly, they were quite elusive when it comes to eventual compensations for having basically rented the most expensive iPod ever in lieu of having a working phone... Will also have to call back to get updates... this is promising...

Upgraded from a 3GS to a 4S about a week after it's release (both on Orange UK). Came with new micro-sim and worked fine for about 3 weeks and then got the 'SIM FAILURE' message out of the blue.

Initially no amount of restores and restarts would get the phone working again and once you restore you can't use the phone again, the sim didn't work in my old 3GS after that failure as well. Spoke to Orange who went through everything again and sent me out a new sim card.

New card worked for about 3-4 hours before the error came back, however this time I could re-boot my iPhone and it would work again fine for 2-3 hours at a time.

Spoke to Orange again and they said the phone needed replacing and it had to go through Apple (which I think is a joke as I bought the phone from Orange and they're my retailer... anyway). I've sent my phone off to Apple yesterday and I'll wait to see what the problem is, was nervous about sending it back as they said if they can't replicate the problem they'll send the same phone back again!

I guess worse case is I cancel my contract with Orange and get an Android instead... not that I want to but I can't live with this problem. I loved my 3GS and never had a days problem with it, very annoyed by this. I'll update when I hear back from Apple.

I'm experiencing the same problem. I hope this is only a software issue. My new iPhone 4s has become an overpriced iPod touch.

So initially my iPhone 4s (black, 32gb, purchase in the uk from apple store on launch day) went "invalid sim" about once per day, switch off and on resolved.  Got a new sim from Vodafone, no change.  After upgrade to 5.0.1 went "invalid sim" 6 or 7 times per day.  Made appointment with apple genius bar (40 mins drive away), took screen shots every time it happened for a couple of days, showed apple guy the screen shots, he replaced the phone immediately.  No problems since (5 days).

guys i just got iphone 4s white 16gb and i had airtel sim an indian 1 but it shows me my network and signal and i m even using internet but i cant make calls and sms's any 1 whos knw about this problem ?????

if the airtel sim card is 64KB (their micro sim cards are 64 KB), then you will have this problem. Exchanging the card for a 128 KB card which Airtel has (it is a mini sim card, which will have to be cut to micro sim size) will sort the issue immediately.  It is likely that the next ios update may sort the issue too, but for immedaite results, change to 128 KB Sim Card.  All the best

Got the same problem here with 4S provided by Orange France and with the micro sim from my iPhone4. Things got better(actually everything was fine) when I switched off the SIM Pin Code but the problem came back since I upgraded to 5.0.1. I restored, rebooted, reinserted my SIM card multiple times but can't get rid of the problem. A friend of mine got his MicroSim the same day I did (back in June 2010) and got his 4S 5 days ago (upgrade from iphone 4) : he never had a single problem.

I called Apple France they told me they never heard of this problem and that I should get a new SIM before sending back my phone. I'll get my new SIM in 48H, if it doesn't solve the problem I will try to get my iPhone replaced. Once some tech guy at Orange told me that this is a known problem but it looks like few people a informed.
