Ask Slashdot: Unlimited Data Plan For Seniors?

New submitter hejman08 writes with a question probably faced by many whose parents, grandparents, and other relatives rely on them for tech support and advice, specifically one about finding an appropriate data plan for his grandmother, of whom he writes: She is on her own plan through Verizon with 1GB of data, and she literally blows through it in three days or less every month, then complains about having nothing to do. They have Wi-Fi at her senior center, but only in specific rooms, and she has bad ankles and knees so she wants to stay home. Internet service would cost 80 a month to add where she lives. What I am wondering, is if any of the genius slashdotters out there know of a plan that- regardless of cost of phone, which we could manage as a gift to her, once- would allow her to have at least 300 minutes, 250 texts, and truly unlimited data (as in none of that Unlimited* stuff that is out there where they drop you to caveman speeds within a gig of usage), all for the price of less than say, 65 a month? The big 4 carriers don't seem to have anything that would work for her. What would you recommend? (I might start with a signal repeater in a utility closet, myself, or some clandestine CAT5 from a friendly neighbor's place.)
