I found the issue !

On our embedded platform, there a CPLD which drive the reset, the power 
and the flight mode of the GSM chips.

And, guess what ? There has been an update of the CPLD sometime ago. And 
this update enables always the flight mode ... !!!

So that, depending of the board I used, the version for the CPLD was 
different (not all my boards were updated), sometimes I could send SMS, 
sometimes not, sometimes the GSM modem was blocked, ...

An update of CPLD code fix the problem !

Sorry for the noise :)

It's time to take a tea and be happy.

Anthony Viallard.
