THIRTEENTH CONGRESS OF THE 
REPUBLIC OF THE PHILIPPINES 
Second Regular Session 
INTRODUCED BY SEN. MANNY VILLAR 
EXPLANATORY NOTE 
The Mobile Telephones (Re-programming) Act creates a number of 
offenses relating to the electronic identifiers of mobile wireless communications 
devices. In particular it becomes an offense to reprogram the unique International 
Mobile Equipment Identity (IMEI) number which identifies a mobile telephone 
handset. It is also possible to interfere with the operation of the IMEl by the 
addition of a small electronic chip to the handset and this too is made illegal. 
If this bill becomes a law, all the major mobile telephone network providers 
will be able to bar mobile telephone handsets, when these are reported stolen or 
lost, by reference to the IMEl number. However, if the IMEl number of the stolen 
or lost telephone is changed, it will not be possible to implement the barring 
process and the telephone will be able to continue in use. 
It is clear from international Global System for Mobiles (GSM) standards 
that the IMEl number should not be changed and that it should be resistant to 
change. Indeed there is no legitimate reason why anyone other than the 
manufacturer of a mobile telephone (or its authorized agents) should need to 
alter an IMEl number. 
It is expected that the creation of these new offenses, taken together with 
the implementation of a handset barring system across all networks, should help 
remove the incentive for mobile telephone theft.
