Hi all, i've this problem: after upgrade to ics random my Ray tell me: "Sim removed: reboot".
Then i reboot and the phone work correctly.
I've already tried this step:
1 - do a factory reset.
2 - format the sd card and do a pc companion "repair software".
3 - Do a "repair software" with Seus.
Nothing works for now, i'm in advice that this problem come up when i use 3g, yesterday i keeped the connection in umts and the problem doesn't come up.
Then i change it in 3g and the problem come up again.
The Ray is Italian (i think), the sim is coopvoce (an virtual operator tha works on TIM line).
The problem come up when i update to ICS, with Gingerbread and the latest firmware of Gingerbread the phone works great and i haven't problem (sometimes don't connect to data but with a switch to airplane mode all works again) so i think isn't a problem of the sim.
Already send an email to support waiting for reply.
What can i do for this problem?
I hope someone can help me.
Sorry for my bad english and tx for answers...
Uhmmm i've uninstalled 2x battery and the problem doesn't come up for one day...
Next days i'll keep tou update
Great! Let's hope that is the culprit!
Nothing, it not work.
Tomorrow i go to coopvoce and change the sim for trying one nw, in email they tell me that they change my sim without problem.
Other than the SIM card, can't think of anything else ....
Ok, i've changed the sim, now watch what succeed...
I'll keep you update.
Will be waiting ....
For now working good 🙂
Great! Finally .... 
Same problem here with Xperia mini. After upgrade to Android 4.0.4
Tryed other SIM Cards and the problem persists. It happens when the phone blocks screen.
It starts soon after the upgrade.
Hi Agdrocha, suggest repairing phone software.
