I bought a discontinued HDX 7 Verizon LTE 4G for 70 $ on sale on amazon for $70 as I needed something for mobile..and then bought this sim kit . Have not had a phone prior to this for decades. I primarily want to use it for data only online access should I travel. Got this card, fiddled a bit but installed fine. At the time of setup, I was automatically given a 1gb free trial by Verizon. All automatically. so for now I am very pleased. We shall see what happens at end of trial. Tip for users of HDX you will need to uninstall a lot of unnecessary apps as it will eat up you data usage doing its housekeeping stuff you dont care about. Bottom Line. so far . .all worked well.
