On a cell phone it's a flat rate, but if you call someone long distance on a landline phone it gets more expensive.
On a cell phone it's a flat rate, but if you call someone who lives far away on a landline phone then the fee goes up.
「遠くにいる人」は “someone who is far away” で、「遠くに住んでいる人」は “someone who lives far away” との言い方もありますが、”someone who is a long distance away” と “someone who lives a long distance away” でもいいです。遠くにいる人に電話をする事を “make a long distance call” と言いますが、 “make a far away call” はなぜか言いません。
