Christopher Columbus was convinced that he could reach Asia by sailing west.
Early explorers used ships as their exploration vehicles. Both polar ocean waters are filled with icebergs and sailing in them is not only dangerous but extremely cold. Until the technology -- reinforced hulls, for example -- supported expeditions into these extreme situations, Antarctica could not reached.
Columbus was trying to reach Asia by sailing west in order to establish a direct trade route for valuable goods such as spices and silks. He believed he could reach Asia by sailing westward instead of the traditional eastward route, which was blocked by the Ottoman Empire.
You should say "you could be reached on a phone no", not "you could be reached at a phone no"But the no at the end of both your phrases is also grammatically incorrect.So you should really say "you could not be reached on a phone," if I understand correctly the meaning of you phrase.
