Android iphonesubinfo

I have an issue executing service call with su and without su. When running the command on device's console I get:

su -c service call iphonesubinfo 5 i32 1 returns

Result: Parcel(
0x00000000: fffffffc 00000023 00740041 00650074 '....#...A.t.t.e.'

Is there any extra permissions that needs to be granted for su?
