It isn't ever easy, that's for sure.

I will say that Verizon isn't going to be inexpensive. It's fairly comparable to AT&T's international pricing:

That monthly data allowance is brutal. 100MB is nothing. The worst part is, pricing will stay high because the target markets are business and infrequent travelers. Business travelers need that US phone # to stay in contact, so their companies will pay. Infrequent travelers don't go anywhere enough to make the money and hassle of switching to a prepaid SIM at the destination be worthwhile.

If you're willing to ditch the iPhone, Project Fi fits your requirements.
