The point is that this forum (especially this topic) is to provide support. If you need to know about Vz. - you would need to contact their CS.
There is no question that Vz covers outlying areas better - for at least the next year. As you probably know, especially if you have 3 or 4 lines on your account, you will be paying double for the privilege. As you also know, you won't get free out-of-country roaming - but that fact doesn't affect most people. .
