I have also used the A705MN as well as the A705W (Canadian Model) they both will work on Verizon. You must have an already active sim card from a Verizon phone. Once you have that you can simply put your activated sim card in the A70 and it will work.
Verizon WILL NOT activate this phoen directly for you and will offer you NO support for it.
It is a great phone btw.
Now that is useful information.
