The Mormons left New York voluntarily to join a large group of converts in Ohio. Some left Ohio to settle a new 'Zion' in Missouri, but those who remained in Ohio were eventually forced out by persecution and violence. The Mormons were kicked out of Missouri by violence and a government issued extermination order. They then went to Illinois, where they also faced severe persecution. After their prophet, Joseph Smith, was murdered, the local government asked them to leave the state.
They then travelled to what at the time was Mexico (now Utah). They thought that by escaping the country and going to a land that was unwanted by any other white people, they might find peace. They did find peace and were accepted by the Native Americans, but Utah was annexed by the United States shortly after and an army regiment was sent to monitor their activities and act as the government in the territory.
Persecution. The Mormons were chased out of Missouri and asked to leave Illinois... so they moved further west, where there was nobody to kick them out.
Religious and political persecution forced the Mormons to move from several states in the east and midwest. In Illinois, their prophet Joseph Smith was murdered due to a political disagreement and the government asked the Mormons to leave in order to preserve the public peace. At this point they decided to move to a place that was largely uninhabited so that they could practice their religion in peace.
The Mormons moved west in search of a new home, not a new phone. Phones weren't even invented yet (this was in the 1840's). The Mormons had been persecuted and kicked out of Ohio, Missouri, and Illinois, so they went further west into what was then Mexico in search of a place where they could live in peace.
The Mormons traveled west in wagons, with handcarts and later by train.
The Mormons were seeking religious freedom. They had been harrassed and kicked out of previous settlements in Ohio, Missouri, and Illinois, so they went west to leave the United States (because at that time the area that is now Utah was part of Mexico).
The Mormons were receiving massive persecution, being moved from New York to Kirtland, to eventually Utah. So basically, they wanted a place to worship their religion in peace
The signifigence of the Mormons moving west was for them to escape religious percsecution
Members of the Church of Jesus Christ of Latter-day Saints (commonly called the "Mormon" church) faced extreme persecution and violence in the east and Midwest, so they went further west in search of a place where they could practice their religion in peace.
