Does VZW charge a 2nd activation fee if I exchange phones within the 15 day window?

No, it also does not restart the 15 day buyers remorse either, so they keep going off the original acount service.remember only 1 activation.your buyers remorse is also 15 days from when the service was activated by not the phone being used and does not restart when swapping out for different model.
