Android phones allow you to automatically add your carrier's code to make long distance calls more conveniently, without having to spend time decorating or typing those numbers. The function can be configured natively, without having to install any extra applications on the smartphone. Thus, the prefix is applied directly when initiating the call.
In addition, you can save on calls if you have a discount package or even free minutes on long distance calls (DDD and DDI) using the specific code of your cellular service provider
