TMobile and Verizon are incompatible. As are every other two separate phone services. The only way to use a TMobile sim card in a Verizon phone, is to get the Verizon "unlocked".

yes its a world phone

For a cell phone to be unlocked, it means that the phone is able to use any SIM card from any phone network type. For example, a locked Verizon Wireless phone would be unable to accept and function with an AT&T SIM card, whilst an unlocked Verizon Wireless phone would be able to accept and function with an AT&T SIM card.
