Q: Invalid SIM Card on iPhone 4S (5.0.1)

At least the error message changes every couple times I restore. Invalid SIM, No SIM, SIM Error. This is upsetting. Restoring, no longer works. If I wanted an Ipod Touch, I would've gotten one. You'd think that Apple would have cleared this issue up, seeing as this thread/problem seem to have been going on for 3 months, but they haven't. Steve Jobs wouldn't tolerate this. I've been with Apple since the II GS, but they are ruining all the brand capital that has been built up over the last couple of decades. PLEASE FIX THIS!!!  Sad in Brooklyn.  

PS.   How are the Droids? Heard the battery life is an issue, but if I can call or check email its a win!!!

I've contacted Apple, and since my Phone is under warranty, they replaced it with a new iPhone 4S. What I liked about it, that it has iOS 5.0.

In my previous iPhone, it was 5.0 and never had issues till I updated to 5.0.1.

I'm using this new iPhoen for 2 days now and never got any issues of 'No Service' nor 'Invalid SIM'. So I will keep my phone on 5.0 and won't update, till we see how 5.1 final works

Happens all the time to my 32gb white 4s (vodafone uk). And it seems to be happening with more regularity, like about 10+ times a day.

I've tried restoring from back-up and all that but it only worked for about 48hrs.

I'm seeing that replacing the phone / sim card isn't helping anyone either, unless anyone here has heard to the contrary?

anyone know if apple are planning on solving the problem with an update / new model sim card or sim tray or new whatever is causing the failure?

Hi

I've the same issue ! My SIM works fine for two months, then the invalid SIM error comes up. At the moment, many times a day it will be happend.

I upgraded the iPhone 4s to 5.0.1 9A406 but it not solved the issue. The remove of the sim PIN not help and at last factory reset also.

In the moment my iPhone is to minum configuration but it consum power, at the end of the day it is empty.

Janba,

it is nothing to do with the sim security. if it is a security it must not start or work at all. but the sim starts working after every trial or reboot. may be after 2hrs or 3hrs of inactivity you find the surprise. once you reboot it agaian starts working. the same sim would work fantastic in ip4 but not in ip4S. it clearly says the problem is only in ip4S. i am also waiting for apple to come out with some solution.

I agree with you sathyam,

it took me a week to replace my iPhone 4S and during that time I used my iPhone 4. Using the same sim card and never got those issues with it.

It is clearly an iPhone 4S issue and iOS 5.0.1. iPhone 4S with iOS 5.0 don't get these issues. so if you're on warranty, change your iPhone and ask them to give you one with iOS 5.0

Is there any way to downgrade the OS to 5.0 and try?

iOS firmware contains 2 parts (firmware, baseband), firmware is the main OS itself, baseband is the software for the GSM or sim ...

if you have the SHSH for your device for iOS 5.0, then you can downgrade, but that will only impact the firmware... and it's impossible to downgrade iPhone 4(S) baseband, and I guess the issue here is not the firmware, it's the baseband of iOS 5.0.1.

In other words, even if you could downgrade to 5.0, you still have 5.0.1 baseband, so the issue will remain.

Thanks for the info. let me think over . in the meantime anyone gets any sort of solution pl update

Invalid SIM Card on iPhone 4S (5.0.1) I have the same problem. I have my iphone restauardo 4S 3 times and still the same error.Now I have a 4S Ipnoe I can only use with iPod.
Someone at Apple can help us with this serious problem that leaves us without phone? Please correct this fatal error when.

Greetings from Bulgaria. Same problem here. The update iOS 5.0.1 (9A406) didn`t solve the problem.

I hope Apple will help us ASAP.It`s very dissapointing to see how iphone 4s become to ipod  like the guy before me said:)

Hope to see the iOS5.1 update soon in Itune. Hope this fixes our problem. Request Apple to release this update soon.

regard

I phoned Apple and they told me the only thing is to change SIM. I've changed 2 new SIm cards and the error still.
Someone please take note Apple and release a solution to users
thanks

Here the same SIM problem.

I've got iPhone 4S since November 2011. Everything right until January 2012. Symptomes: Every day in the morning the message "Invalid SIM". After restart all OK. In the end of the month I got several messages a day: "no sim installed", "Without network". Other times the network indicator was strong but in real i was nor connect to the network. I've changed the micro-SIM 2 times but nothing was solved. I went to the operator that sold me the iphone, in Portugal, and now i'm waiting for a "repair" or a new iphone. Meanwile i have to wait 2 or 3 weeks.

It's impressive that the called by apple "the best iphone ever" has this problem for so many time unsolved. This is an high-end phone. It should not have ... a SIM problem....... Plese Apple, shame on you. Solve the problem.

@grgi- can you please send me the link to download 5.1 beta 3
