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

Thank you for the insights.

If what you say is true, then I think it would be sensible for Apple to maintain a list of carriers that can support their unlocked phones, or at least put the language that describes the requirments into their sales materials.

I had an unlocked 4s that experienced the "sim failure" problem on t-mobile USA and my only option was to return the phone to Apple for a refund.

Of course, not supporting normal SIMs and GSM networks could just be a colossal mistake. We'll find out when the next version of iPhone Baseband and Modem firmware is released. If you have access to the iOS developer program, I'd love to know if the Beta of 5.1 fixes your problem ....

Thanks for the insights, what you write makes some sense. As I wrote, I wasn't sure whether it was the new SIM or the tape. However, here's where I'm lost. I cut my wife's SIM down to a uSIM as well, and she's not experienced any problems. So it would seem that it is a combination of SIM and iOS version. I (and more importantly she) don't feel like testing it out by updating her OS to 5.0.1 to see if she starts experiencing the problem.

I'm just thrilled that my phone is working again.

I'm in the process of installing iOS 5.1 on my wife's iPhone 4S that has the "invalid SIM" issue. Previously, nothing helped (incl. hard reboots, full restore, SIM PIN switched off, tape put on the SIM card etc.). If 5.1 beta doesn't help, I'm returning the phone.

Doing the same right now! 4S 16 gb from Finland!

I live in Russia, St. Petersburg and got this phone as a present. With some troubles...

I can't buy microSim of my operator (Tele 2 Russia) becouse they have only standart Sims, so i cutted it.

On my last iPhone 4 it worked very nicely, but with 4S... iTroublePhone =(

I'll write after installing 5.1 beta

I got fail =( I didn't register my UDID =( so waiting for imzdl =(

I live in SPb too and my Megafon is my cellular operator. I've changed 5 SIM-card already (2 micro-SIM and 3 regular SIMs) but my iPhone 4S 16Gb from UK works with troubles too. I get some "SIM failure" messages but mostly it is just "no network" error. Seems there is not cellular operator in Russia who can provide 128k sim-cards..

По-русски писать можете? =)

Я ставил 5.1, а UDID еще не активировали мне ( В итоге проишвка встала, а активировать телефон не могу. Даже не знаю что делать, если не получится заставить телефон работать по нормальному, ехать в Финку менять?...

Having issues too with my microSIM(non cutted) with Orange France. Requested new SIM got it yersterday. They don't know if it's a 128k and there is nothing written on it besides MFD 12/2010. The chip on the new sim looks different, the pins/pads are having a more curved shape and it looks like the chip is not touching the sim tray anymore. I'll keep you posted in 24h if the problem is solved (or not).

Я откатился. Зашел в DFU и он предложил восстановить телефон. Залил вот обратно 5.0.1

А как мне подтвердят UDID то я снова залью 5.1 и активирую

Пипец как обидно что телефон по-нормальному не пашет. Потратили кучу денег а оно не пашет (

Nothing, that's the thing. I took the phone to the store, they had a look at it there, checked that everything was working ok. They took out the SIM card and put it in again, something I also tried myself, and that's it. It's been working fine ever since.

Hehe could be!!

The guy in the store told me to contact my provider and ask them to give me a new SIM card. My provider told me to contact their tech support first though. I decided to wait and see if the problem would appear again, but so far it hasn't.

У меня те же проблемы что и у Вас, только с Билайном, 16 Gb из Франции. Я меняла SIM-карты, восстанавливала заново ( и как новый телефон и из резервной копии), но все по-старому. Не работает, хоть ты тресни. Пропадает сеть, звонить дает только после перезагрузок и то через раз и через пару часов пишет "Ошибка SIM", чтоб его этот Iphone!

This is rediclous!!! I bought my phone during my trip and now I can't go back and exchange it... "Sim card failure" message appears almost every day... I even had my simcard replaced hoping it would help... I still have hopes for a new iOS update... if it doesn't fix the problem and there is a flaw in hardware, what's gonna happen?? I don't think Apple will recall those millions of iPhones they sold for the past few months. 😟

I need answers, Apple!!!!!!!!!!

An update:

The TAPE method of covering the conduction points along the SIM edge did not work. The issue recurred later that day. I removed the tape and took the next logical step and called support at Apple and Verizon.

I sat through support via phone with both Apple and Verizon.

I learned from Verizon that the SIM card is required in the phone for the phone to operate, even if you do not use the SIM CARD and are on a CDMA network. It is an apple design "Feature".

In my case, the Apple team claimed to isolated the issue down to the SIM or Carrier. This bumped me to Verizon support.

For Verizon users, Verizon can apparently remotely deactivate the SIM on your phone to prevent it from getting the SIM FAILURE problem, but it disabled the Global capability of the phone. Since I am back in the US and not traveling for another month, I opted for the deactivation and SIM replacement. Since they deactivated my SIM, I have had no issues. Verizon is sending me a new SIM via Fedex with an expected delivery of today.

The Verizon support person indicated this has been a common issue and the problem appears to be from a large batch of faulty cut or faulty manufactured SIM cards provided to APPLE at the manufacturing facilities.

My new SIM will arrives today. Fingers crossed

Talked to third line support in Sweden/Swedish today. They acknowledged the problem, mentioning three different kind of SIMs and that they were on the problem. They couldn't do anything right now but hoped the new iOS will fix it.

What I can see from the beta testing, that'll'nt happen in 5.1!?
