I guess I still like the idea of having my phone and iPad on different networks for travel, especially car trips where we might be finding holes in one network's service. It doesn't cost any more since the iPad cellular service is independent of the phone contract.
Network overloads and holes in service are not "disaster planning", but rather provider reliability metrics. IMHO, disaster planning is for storms, earthquakes, and other natural disasters that might deprive one of technology for some period of time. Of course, having a secondary provider will protect one against network overloads or holes in service, provided the second provider is truly an independent provider (different infrastructure). I missed your intent given the title of the post.
