Reading Sim HPLMN data on phone bootup?

Question

Hi All,

Is there a way to read the sim HPLMN on phone boot up after the modem service is up. According to my knowledge we would need to write a service which has to be invoked in the init.rc file and this services communicates with modem service and gets the sim related data's.

Is the right way to do it or is there any other way which allows my service to read the HPLMN number of the sim on phone power up

Thanks, Nik..
