Shortly after installing the rom, a SMS was sent, but it has a cost, and is an international SMS!
I found that is automatically sending SMS to number +918527121333.
This is a tracking system that sends a SMS when the SIM card is exchanged.
To solve it simply, I suggest removing the apk and install another SMS manager such as Handcent SMS.
See the code attached, inside the app Mms.apk number is +918527121333
The phone is a GT-S5360B and everything works, and it has no relationship with csc.apk and your settings.
The settings menu has the android option "SIM alert" and "remote" that did not work, perhaps because anything is missing, anything Samsung apk.
