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

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 (

ну хоть откатился и то радость! вот не понятно, почему нам не дают хотя бы откатится до 5.0.0

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.

А если через DFU и вручную выбрать файл прошивки? Не получится?

Strange help -_-

нет, они запретили откатывать прошивки на младшие версии.. я пробовал, ругается iTunes

May be they haver a shaman in their store! :-D

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.

Just Install the iOS 5.1 beta (developer only) and it will works fine.

Wait for about 1 - 3 hours and tell us. When u reinstal 5.0.1 no problems too, but after some time...

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!!!!!!!!!!

Ya svoi v Bangkoke kupil... Teper' dumayu chto delat' s nim... kajdyi vecher odna i ta je istoriya- SIM CARD FAILURE!!!

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

5.1 Beta 1 DOSN'T solve the problem.
