My nexus 5x kicked the bucket yesterday, so I've been griping about having to buy a new phone. While looking around, I noticed that you can order data-only Fi SIM cards intended for tablets, which don't have a monthly fee, just the $10/gb for data.
My SO is on my plan, so we pay $20 (my line) + $15 (his line) + data. What's stopping us from cutting one of the lines, putting a data-only SIM in his device and calling it a day?
I guess he'd have to do the google voice hacks to keep phone capabilities (and potentially pay like $20 to keep his number if he wants to) but that seems relatively minor in comparison with saving $15/mo. Am I missing something?
