I currently have a bunch of USB modems on Verizon on a data-only plan, which has lower rates for data than plans that include smartphones. I would like to add a tablet to the plan. The thing is, I don't want to haul around a 7"+ tablet - I'd like a tablet that's only 5". Of course, once you get to the 5" screen size, everything is a phone. Is it possible to get a smartphone (I'd pay full retail for one) to act like a tablet instead of a phone for billing purposes? I.e. I pay $10 or $20 a month, share data with the rest of my devices, and have no voice/text support? I was thinking I could activate a sim on a tablet then toss it in a smartphone and just use the smartphone as a tablet (I don't care if WiFi hotspot doesn't work), but Verizon sales people keep telling me it won't work, and I haven't seen anyone who has said they've done this before. Would like to know if it'll work before I shell out for a Verizon smart phone.
