Is it a bug with the sim card? I think more likely to be a software problem. The strange thing is that the data counter remains the same, it is as if I had not spent any additional data.
I only know what is being spent because I get warning message from my cellphone carrier.
The data is always spent near or after midnight.
Tried block all data with Android Firewall. No luck, the log remains clear.
Tried edit the APN's password. Fixed for one day, on the next day in the morning, data was spent again, even with the wrong password
It seems to be a recurring problem with the 805 model, other people are having the same problem.
I'm in stock Android 4.4.2 with Dorimanx's kernel, but this problem also happened with the stock kk kernel.
I really appreciate if someone could help me with this problem.
PS: Sorry for my crappy english
