How To check how many remaining attempts on your Sony Xperia?
Open phone keypad as if you were to dial a call number
Type exaclty this: *#*#7378423#*#*
A SIMLOCK menu appears: go to "Service Info" > "SIM Lock"
Look for the line containing "Network"
This should looks like this: [X] Network 5
IMPORTANT: If the number at the end of the line is equal to 0 (zero), this means that all attempts have been used and you will not be able to enter our code, you will get a message like "unable to unlock network".
