Problem: SIM card removed

[MihailSaint]

Hello!

Sorry for my bad English, I have Xperia S - for the last 2 months of no problems, but now the trouble "SIM card removed   The mobile network will be unavailable until you restart with a valid SIM card inserted.  Restart ..."

At mobile operator SIM card replaced with a new, 3 days the problem was not observed but now reappeared. Most often seen in network activity (using the mobile network 2G/3G)  and games (possibly due to heating). I also noticed that this problem started to appear after update 4.0.4

I have exactly the same problem, and it only seems to happen when switching between 2g and 3g or turning on airplane mode.

I hope someone has an answer for us

Same here, but in random and only when activating Airplane mode. After returning to normal mode (turning off Airplane), network is fine so I'm ignoring it and crossing my fingers for sony to fix it in JB:smileylaugh:. Yes, happened only in ICS. Never occured in GB.

Recently I made a factory data reset, but the Android version 4.0.4 and left the problem persists-_-
