Well Folks - I am a Piglet!
I have used 1gb of data on Fi in less than 24hrs.
admittedly 500mb is SpeedTest.
I like the service, while I've only had it in town and not outside of town, it's worked real well.
But with my Daughter being an Apple fan and having unlimited data - I think I'm headed over to the VZW store for a nano sim.
Even if I translate the $50/mo for data to 5gb on Fi. I still have my daughter on VZW and though I could convert her to a capped plan, I think in the long run, I'm better off sucking up VZW data. The eMail from Fi this morning was a shock, since I've never ever worried about data usage.
The day may come when she pay's her own way, but at least until she finishes college, it's all me.
