iPhone 5 CDMA and R-SIM8 - NO SIGNAL
 

Hi, I have an iPhone 5 CDMA version locked to AU KDDI JAPAN.
I bought a R-SIM 8, installed the patch with iOS6.1.4 and all works fine.
Then a updated via OTA to iOS7 and I have no signal. It says "invalid SIM" and didn't recognize my SIM card. Even the menu to select the carrier doesn't show anymore.

Ps: the nano sim I'm trying is TIM from Brazil.

What can I do? Please help me.
Thanks!

try with un-cut nano sim!
it will work

I'm test R-SIM 8 with cut SIM of Oi and uncut SIM of TIM. Both are recognized. My problem is 2G/3G/SMS, but for call, it's OK.

My iPhone is problematic Sprint CDMA.

My sim is uncut man.

Como vc atualizou? Eu atualizei pelo próprio iPhone e quando reiniciou já apareceu "SIM inválido". Tiro e coloco o chip e nem aparece mais aquela opção de escolher a operadora. Só fica "SIM inválido". Meu chip da TIM é normal, não é cortado.
Se puder dar uma ajuda, agradeço!

rsim 8 doesnt support ios7 for 3G and SMS

For sprint device? Maybe, for now. I have myself 4s running iOS 7 with RSIM 8 and its working good except for USSD commands

Eu atualizei pelo iTunes com um SIM da Oi cortado, mas no momento estou usando um da nano da TIM.

I updated through iTunes with a cut Oi SIM, but at the moment I'm using a nano TIM.

Vou tentar dar um restore pelo iTunes usando o chip original da KDDI e depois colocar o R-SIM8 com o nano da TIM.

I'm gonna try do restore with the original carrier SIM, then try to put R-SIM8 with uncut nano.

Olá,

Talvez você pode ter escolhido o modo errado no menu do R-SIM. Eu fiz um teste escolhendo MODE1 FOR ios6 i4S e deu o erro de SIM Inválido. Minha solução: colocar um SIM de outra operadora (que não seja Claro, pois não funciona em ela) e escolher o modo correto (MODE2 FOR ios6 i5). Funcionando é só voltar pro seu SIM da TIM e repetir o processo usando o MODE2. Espero que funcione.

Hello,

You may have chosen the wrong way in the R-SIM menu. I tested choosing MODE1 FOR iOS6 i4S and gave the error Invalid SIM. My solution: put a SIM from another carrier (other than the Claro because it does not work on it) and choose the correct mode (MODE2 FOR iOS6 i5). Working, just go back to your SIM from TIM and repeat the process using MODE2. Hope it works.

Mas depois que eu atualizei para o iOS7 nunca mais apareceu essa opção do R-SIM. Muito estranho...

But after I updated to iOS7 I don't get this R-SIM option.

Go to Settings-Phone, and look below. There's SIM application menu. You can choose the option there.

I looked and there's nothing, only data network, LTE, roaming, personal access, call time, data use and restore statistics.

Like I said, putting a SIM card from another carrier, this manu appears automatically. Then redo the process with the SIM card before.

I found something else by putting a carrier other than the original, you can take that same problem.
