i'm trying to create a app that allows users to immediately receive all information pertaining to their data/ remaining pulsa.
1. detects what sim card is slotted in
2. collects the data from telkomsel/xl
3. Displays it on screen
It should be very simple. You just need a database stored in the phone for all carriers and how to access the data. you also need to parse the recieved data from the carriers.
