A Boost Mobile Phone cannot be used on or taken to a Verizon Wireless Store or Carrier and be used on Verizon Networks. First off places like boost want to gain customers so they will give customers a phone for far less then what it costs them and they will lock the phone (Carrier Subsidy Lock) so it cannot be used on another carriers service some savvy customers have found that they can unlock a boost mobile phone and take it to sprint or ting and it will sometimes work, Why? Because Ting, Republic Wireless and other Sprint MVNOs Use Sprint Network so theres really no difference here you will be on the sprint network regardless using the Same Bands (Frequencies)Taking your Verizon Wireless (Or Other Carrier SIM) Will not work in that Boost Mobile Phone as the frequencies that boost uses are not the same as Verizon.
