Here's what I want to do: I want to be able to buy an iPhone at full contract price, and only have it active with a data plan. Specifically, I have a Verizon Share Everything data plan that currently is hosting four iPads (no phones) and I want to pop an iPhone on there in the exact same fashion and have it use data from the pool. I don't want a voice plan, I don't want a texting plan. I don't want it to do any sort of voice calling or SMS/MMS messaging beyond iMessage (and any third-party messaging apps). I literally want this to function like an iPod touch with cellular (if such a mythical device were to ever exist) or like a really small iPad mini with cellular. That said, I know that Verizon (and I'm sure the other three major US carriers as well) will not let me outright do this as they'll require a voice and messaging plan for such a device to be activated on their network. That being said, could I: - Get either a Verizon iPad mini (either of the first two generations), Verizon iPad Air, or any cellular iPad Air 2/mini 3 with an accompanying Verizon SIM card - Activate said iPad on the plan (so that it activates the SIM card on the plan with just data) - Then pop out that SIM card (and presumably turn off data on the iPad) and pop it into any otherwise compatible Verizon iPhone 5/5c/5s/6/6 Plus and have it continue to be using just the data plan that I activated the iPad to have joined? Does this work? It's more roundabout than is optimal, but if this is the way to get what I want (which, again, is an iPhone running on Verizon's network as part of my pre-existing share plan with data only), then I'm totally down to do it.
