Yes this is particularly nice if you buy a discounted Verizon gift card online - you can load it to your account so that it can't be used by the seller.
Yeah I had similar problems with the att switch program also.

Why not get Google Fi whenever you need international and use which ever one that you feel are better value with AT&T/Sprint/Verizon or which ever MVNO that you like? There surely are better method...
I don't think I've ever seen band 2 on the north side. The far south side and south suburbs doesn't have B2 either. AT&T needs to get moving on that.
