I am looking for some options by which I can encrypt my calls. First I am looking for a device that comes with features. It does not matter if it is a Android, or Windows or Blackberry phone. I need option by which I can encrypt them. I think Android might be having that functionality. But using third party apps is safer. I tried contacting the telecom provider about this. They said there are not such service, and if you need the same then you can try blackberry phones.
