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

Same problems in Romania and after installing 5.0.1

Different sims and restore and all the other stuff didn't work

Fail in network issues. I hope that next up-date software will solve this problem.

Latvia,Tele2 LV, iPhone 4s, 16 gb, 5.0.1

Using it for 2 days, yesterday I made 3 calls out of 50, today 0 out of 30, something like that. And yesterday I was able to receive something about 15 calls, today the same. Today at day all the time had “No Service” message, now at home it shows 3 service bars and can receive calls from my second phone, but can’t call anyway. Here in Latvia is no Apple store, so I have 14 days from purchase date to return it and get all money back, it was unopened for 3 days so I have 9 days left.

I thought that I pay for quality, not for brand. But now it looks like message from Apple to the world: “Look, we can sell very raw product and even with it beat selling records.” There is no any official message from Apple that they know that this problem exists (I don’t believe that they don’t know) and that problem will be solved.

I like iPhone 4s very much, but I would like it more if it would be able to act like a real phone. If in a week there won’t be any information or updates from Apple that this will ever be fixed, I would have no choice, only to return this to shop and buy phone with Windows or Android. If I would want iPod, I would buy iPod. I needed iPhone, but got iPod. No, that’s not the deal. And there is no prove that this problem will EVER be solved.

Since turning off cellular data I haven't had a problem, the battery has also only gone down 8% in 4 hours whereas it would have been 30-40%.

So it looks like this is the cause, as least for me. Is this a known fault in 5.0.1??

Same problem here. Bought an iPhone 4S (White, 32 Mb - AT&T) on Monday, and toninght I began getting "Invalid SIM" error messages. After turning the iPhone off and on again, I was able to get again a signal but then the call dropped and the same error message appeared again.

Have someone report this long thread to apple feedback? Cause if you dont, its useless to keep complain on this thread..

I've been in China for 3-4 weeks over the past 2 months and this has happened two times. Its like the phone just stops recognizing the SIM card. I can pull it out and put it back in and there is NO message on the phone. Generally when its like this I can send text messages but cant recv anything. Its beyond frustrating.

pluck007: I am glad that you got your phone replaced and I'm happy that it's now working for you. since you are also in Poland, can you tell me whether the phone you purchased was bought through T mobile PL or did you buy it from Apple in Poland or somewhere outside of Poland? And most importantly: how come you got it replaced so fast, considering that there is no Apple Store in Poland (I mean the physical store). thanks. My phone was originally bought in London and I just gave it back to Apple here in PL via Cortland... they told me I'd have to wait 21 days :-(((

Guys, I don't get Invalid Simcard message anymore, but I still do loose network, but you know what, it happens only when I am on using my data network. I've spend last 1,5 days at home and was always on wifi and didn't have any problems. Today I went out to the grocery store and lost signal for 20 mins till I took the simcard out and put it back. I think it's a trend. last time I've lost connection was outside the house as well.. So I still have hopes it's a software issue and will be solved with the next update. Fingers crossed..

BTW, I've call Apple Care yesterday and they said, there is no solution for this issue yet... 😟

Update from my side:

About "No service":

Left phone for night, in the morning got "No SIM" message. Rebooted phone, it found operator. As I can see, while I get service I can recieve calls, it's great. Sometimes if somebody calls me - I can reply. After conversation - no network again. But every time when I try to call by myself I can't even cancel a call - I lose network and its Searching for 1-2 minutes. I don't know what exactly I did, but now my iPhone acts like a phone for 20%, kind of good news.

About battery:

I have disabled 3G, location services, wifi all stuff and with 100% battery before sleep now i've got 66%. Used for 1 hour and 9 hours of waiting (I was reading a book on min brightness)

How did you switch 3G off?

Settings->General->Network->Cellular Data

But I think this did not help me a lot. Also disabled PIN check does not help. But maybe it will work for you, good luck then!

Well.. You switched off data transfer at all. There is no any way to switch 3G on 4S as I know.

Cellular data off works for battery draining but I did get a sim failure during the night :( just less frequent.

Well after switching Cellular data off there is no 3G icon near operator.

By the way very weird thing - after night in morning i get "No sim" message, during day it's most time in Searching and No service state and at evening I almost dont have "No service" problem.

This problem needs to be fixed ASAP, but as I can see you, guys, have it for one and a hald month. How much more time will it take? I feel very upset because of this.

Altec,

I have the same problem!

I've changed the microSim 2 times already.

Are you on Cosmote network?

...I still refuse to believe that it's the iPhone flaw! 😮
