Comparing it to mobile phone, telephone is not very good. It is because when you have the mobile phone, you can receive text messages and calls at the same time.
Telephone is not savvy because it consumes electricity although you are not using it. It is cheaper to use mobile phone. It is not good for personal use. There will be times that you will not be comfortable using it because of its lack of features. It is very not easy by using this only.
