On 17 of January 2017, around 23.45, I was on the phone but suddenly I heard a message saying that I would have just 1 minute. Suddenly I lost the phone call, perhaps the 1 minute... Then I tried to call back to previous number and I heard a message: "System is busy please try later". I have waited 10 minutes, restarted the phone and then I tried to do a call and once again I was unsuccessful. So I tried to call to 789 and I heard the same message. Right now seems I don't have"permission" to do phone calls and to access to the internet but the weirdest thing I can text!
