Recently, I have been charged with a bill that's way beyond my expectations. I checked the account just to be sure if the clerk's claim was real, and it was. The clerk said it had something to do with 'java games'. But as far as I can remember, I haven't subscribed to any providers. And, I don't know what services I have been subscribed to since the SIM is being kept at the router at all times, wherein it doesn't store nor receive any messages at all. Could you please tell me a way to know all the things that charges from me?
