How Can I start a business of making phones like Nokia, Motorola, etc?

First you need to know which components you need in your phone, the source of them. Then someone will design decent software.  

Then 

You need a place to build the phone and also a place to make the outer shell to hold the components then staff need to be trained then advertising and get big business to you. Naked is a big job in the company investing millions big enough to produce a new product.
